Hello fellow Ottawa gardeners! As the crisp autumn air settles in, from downtown patios to sprawling yards out in Kenmore, our thoughts might turn to pumpkin spice and cozy sweaters. But wait, before you hang up your trowel completely, there’s more to fall gardening than just raking leaves! This season is actually the prime time for a super useful task: perennial division.
Ever notice how some of your favourite perennials – those plants that come back year after year – get a bit overcrowded, or maybe the centre starts looking less lively? Perennial division is simply the process of carefully digging up these established plants and splitting their root clumps into smaller, healthy sections. You get more plants (bonus!) and revitalize the original one.
Why tackle this now in the Ottawa area? Fall offers cooler temperatures and usually decent moisture, which means much less stress and shock for the plants compared to the summer heat. It gives their roots a chance to settle in and establish themselves before the ground freezes solid. Think of it as giving them a helpful refresh before their long winter nap! It’s a key part of smart gardening and landscaping maintenance. Stick with us, and we’ll dig into which perennials love a fall split and how to do it successfully.
The ‘Why’: Unpacking the Benefits of Fall Division in Our Climate
So, we know what perennial division is, but why bother doing it in the fall here in the Ottawa region? Isn’t it tempting to just tidy up and call it a season? Well, grabbing that shovel one more time before the snow flies can pay off big time for your garden’s future. Living in our Zone 5a climate means we have a specific window of opportunity, and fall often fits the bill perfectly. Let’s dig into the rewards!
1. Giving Your Plants a Health Spa Day
Imagine being crammed into a crowded bus for years – not fun, right? Your perennials feel the same way! Over time, clumps get congested.
- Better Air Flow: Dividing perennials thins them out, allowing air to circulate freely around the base. This helps prevent fungal diseases that love damp, crowded conditions – kind of like airing out a musty basement.
- Rejuvenation Station: Does the centre of your favourite Hosta look a bit sad and sparse? That’s common! Division allows you to remove any old, woody, or dead bits in the middle and replant the vigorous outer sections. It’s like a fresh start for your plant pals. Healthy roots mean healthy plants ready for next spring’s growth spurt. Good soil and healthy roots are fundamental to successful gardening.
2. Size Matters (Keeping Things In Check)
Some perennials are enthusiastic growers (we’re looking at you, Bee Balm!). Left unchecked, they can start bullying their neighbours, hogging sunlight, water, and nutrients.
- Maintaining Order: Division is the perfect way to manage the size of your plants, keeping your garden design looking intentional and preventing aggressive plants from staging a hostile takeover. Think of it as gentle landscaping crowd control. It keeps your borders looking sharp, whether you’re in Nepean or tending a smaller urban plot.
3. More Plants? Yes, Please! (Free Propagation)
This is arguably the best part – free plants! Every time you divide a perennial, you create multiple new plants from the original clump.
- Expand Your Garden: Fill in bare spots elsewhere in your yard without spending extra money at the nursery. Score!
- Share the Love: Got more divisions than you need? Share them with friends, family, or neighbours! It’s an eco-friendly way to spread beauty and gardening joy. Plant swaps are fantastic community builders. Plus, if you’re tackling a big fall tidy-up anyway, perhaps using a service like the Kenmore Garden Clean Up Service, you’ll have plenty of divisions ready to gift.
4. Less Stress = Happy Plants (Especially in Fall)
Remember how we mentioned cooler temperatures in the intro? This is HUGE. Trying to divide and replant perennials during Ottawa’s sometimes scorching summer heat puts immense stress on them (transplant shock is real!).
- Cooler Air Temps: Fall’s crisp air means the leaves lose less water (transpiration).
- Warm Soil Temps: The ground is still warm enough from the summer sun for roots to grow and establish before the deep freeze sets in.
- Autumn Rains: Mother Nature often helps with watering, although you’ll still need to keep new divisions consistently moist until the ground freezes. Efficient watering is key; some gardeners even use methods outlined in this to ensure roots get the hydration they need.
- Less Competition: Weeds are generally slowing down in the fall, giving your newly divided perennials a better chance to settle in without competition. This whole process is a key part of getting your beds ready for winter, complementing other tasks detailed in guides like .
Fall vs. Spring Division: A Quick Ottawa Comparison
| Feature | Fall Division (Late Aug – Early Oct) | Spring Division (As soon as soil is workable) |
|---|---|---|
| Pros | – Cooler air = less stress – Soil still warm for root growth – Often better natural moisture – Frees up busy spring gardening time | – Full growing season ahead for establishment – Easy to see emerging shoots – Avoids disturbing fall/winter interest plants – Good for summer/fall bloomers (divide opposite bloom) |
| Cons | – Risk of frost heave if roots don’t establish – Can be harder to locate dormant plants – Might sacrifice fall flowers on late bloomers – Winter survival depends on good root growth | – Can be wet & muddy – Plants expend energy on roots and top growth – Busy season! Lots of other tasks demanding time. – Hot, dry spells can quickly stress new divisions |
Essentially, for many common perennials in our Zone 5a climate (like Hostas, Daylilies, Peonies, Irises), fall division works beautifully. It allows the plant to focus solely on root development before winter. Spring division is often better for grasses and plants that bloom late summer or fall (like Asters or Sedum ‘Autumn Joy’). Think of fall division as setting the stage, whereas spring tasks often involve different priorities, such as feeding your lawn following tips like those in the . Just like lawn care differs from garden bed maintenance – you wouldn’t use the same approach detailed in the for dividing your perennials!
Dividing perennials might seem like just another chore, but it’s truly an investment in the health, beauty, and longevity of your garden. And if the task feels a bit overwhelming alongside other fall cleanup, remember there are always professional Landscaping and Gardening Services available to lend a hand. Happy dividing!
Timing is Crucial: Your Ottawa Fall Division Calendar
Alright, garden superheroes, let’s talk timing! When it comes to dividing perennials in Ottawa, getting the schedule right is almost as important as remembering where you left your favourite trowel. Our unique climate, swinging from sticky summers to bone-chilling winters, gives us a specific sweet spot for this task. Miss the window, and your newly split plants might throw a frosty tantrum. Hit it just right, and they’ll settle in beautifully before their winter slumber.
The Golden Window: September to Mid-October
Think of early fall in Ottawa as the ideal moving day for many of your perennials. Generally, the best time is from late August or early September through to about mid-October. Why then?
- Cooler Air: The scorching summer heat is (usually!) behind us. Cooler air means less water loss from leaves, reducing stress on the plant. Phew!
- Warm Soil: The ground is still holding onto summer’s warmth. This encourages roots to grow and establish before the ground freezes solid, which usually happens sometime in November around here.
- Nature’s Watering Can: Fall often brings more reliable rainfall than summer (though don’t count on it entirely – keep that hose handy!).
- The 4-6 Week Rule: The goal is to give those new divisions about 4 to 6 weeks to develop roots before the ground freezes hard. Working backward from a typical early-to-mid November freeze-up in Ottawa puts us squarely in that September/early October timeframe.
When to Divide Common Ottawa Perennials
Your Fall Division Hit List (The “Go For It!”)
These common garden residents generally love being divided in the fall in our area, especially since most are spring or early summer bloomers:
- Hostas: Get too crowded? Fall is perfect for splitting these shade lovers.
- Daylilies (Hemerocallis): Super easy to divide and bounce back quickly.
- Peonies: Best divided in the fall to minimize disruption to next year’s blooms. Be gentle!
- Bearded Iris: Divide every few years after they finish blooming, usually late summer/early fall.
- Astilbe: Does well with fall division in moist, shady spots.
- Phlox (Garden Phlox): Helps rejuvenate clumps and improve air circulation.
- Bleeding Hearts (Dicentra): Can be carefully divided once dormant in the fall.
- Coral Bells (Heuchera): Divide when the centre gets woody or lifts out of the ground.
Hold Your Horses! (Wait Until Spring for These)
Some plants just don’t appreciate being disturbed right before winter. It’s often better to divide these in the spring as new growth appears:
- Ornamental Grasses: Most grasses prefer spring division.
- Chrysanthemums (Mums): Need all season to establish for winter survival.
- Asters: Bloom late, so dividing in fall sacrifices flowers and weakens them before winter.
- Sedum (like ‘Autumn Joy’): Late bloomers; wait until spring.
- Butterfly Bush (Buddleja): Can be borderline hardy here; spring division is safer.
- Russian Sage (Perovskia): Doesn’t like fall transplanting.
A Simple Ottawa Fall Division Calendar Concept
Think of your fall gardening schedule like this:
- Late August/Early September: Scout your garden beds. Which perennials look overcrowded or weak in the center? Make your division list. Check your tools. If some early bloomers (like Iris) are ready, you can start now. Begin serious weather watching. Ensure you have good compost ready as part of your Soil preparation for the new planting holes.
- Mid-September to Early October: This is PRIME TIME! Focus on dividing the plants from the “Go For It!” list. Work methodically. Water new divisions deeply. Seeing the transformation can be really satisfying – if you want inspiration, check out our gallery for examples of thriving gardens.
- Mid-October Onwards: Getting risky! Only divide if absolutely necessary (like rescuing a plant during construction). If you do, be prepared to offer extra winter protection, perhaps with a good layer of mulch applied after the ground starts to freeze (a task often done alongside final mulching and edging). Focus shifts now to leaf cleanup and other winter prep. If the overall fall workload seems daunting, remember that help is available, whether you need a full Ottawa property cleanup service or more localized support like a Marionville property cleanup service. Even smaller tasks, such as those handled by a Kenmore Garden Clean Up Service, often include preparing beds for winter.
Listen to your garden (and the weather!). While September-October is the general rule, use your eyes and ears (well, weather apps!).
- Plant Cues: Are the plants looking a bit tired? Have they finished blooming for at least a few weeks? Are the leaves starting to yellow naturally? These are good signs they’re winding down for the season.
- Weather Forecast: Avoid dividing during a surprise late summer heatwave. Aim for a stretch of cooler, preferably overcast or showery, weather. Keep an eye on the long-range forecast – if an unusually early deep freeze is predicted, get dividing sooner rather than later!
- Microclimates Matter: Your garden’s specific location plays a role. A sheltered garden in Manotick near the river might have a slightly longer window than an exposed, wind-swept garden further out in Greely. Pay attention to your yard’s conditions.
Quick Tips for Success:
- Water the plant well a day or two before dividing.
- Dig widely around the plant to get as much root ball as possible.
- Use a sharp spade, garden knife, or forks back-to-back to gently pry or cut the clump apart.
- Ensure each new division has healthy roots and several buds or shoots (eyes).
- Replant promptly at the same depth they were growing before.
- Water thoroughly after planting and keep moist until the ground freezes.
By respecting the fall division calendar tailored to our Ottawa climate, you’re setting your perennials up for renewed vigor and a spectacular show next spring. Happy dividing!
The ‘How-To’: A Step-by-Step Guide to Dividing Like a Pro
Alright, let’s roll up those sleeves and get down to business! Dividing perennials might sound intimidating, but trust us, it’s more like careful plant sharing than scary surgery. With the right approach, you’ll be multiplying your favourite plants like magic. Here’s how to tackle it step-by-step, making your Ottawa garden beds even more beautiful.
Step 1: Gear Up!
Before you even think about digging, let’s get your toolkit ready. Having everything on hand makes the process smoother (and less muddy back-and-forth to the shed!). You’ll likely need:
- A Sharp Spade or Shovel: For digging up the plant. Sharp is key – it makes clean cuts and requires less brute force.
- Garden Forks (2 ideally): Excellent for prying apart fibrous roots without tearing them too badly. Think back-to-back leverage.
- A Sturdy Garden Knife or Old Serrated Knife: Great for slicing through tougher crowns or tightly packed roots. An old steak knife works wonders!
- A Tarp or Wheelbarrow: A place to put the plant once it’s out of the ground, keeping your lawn cleaner.
- Watering Can or Hose: Essential for watering before and after.
- Gardening Gloves: Protect your hands!
- Pruners: To trim back foliage if needed.
- Compost or Other Organic Matter: For amending the soil – more on this critical step below!
We’ve learned a thing or two about successful gardening over the years (you can learn more about us and our experience here), and having the right tools, especially sharp ones, makes a world of difference.
Step 2: The Great Escape
Okay, deep breaths! Time to gently evict your perennial from its current spot.
- Water First: If the ground is dry, water the plant well a day or two before you plan to divide. Moist soil is easier to dig.
- Dig Wide: Start digging several inches away from the base of the plant, creating a circle around it. You want to get as much of the root ball as possible, not slice right through the main roots.
- Go Deep: Angle your spade slightly inwards and downwards as you dig around the circle.
- Leverage Gently: Once you’ve dug all the way around, use your spade or fork to gently lever the plant clump out of the ground. Try to lift from underneath the root ball. Get a helper if it’s a really big, established clump!
- Place it Down: Move the entire clump onto your tarp or into the wheelbarrow.
Step 3: Divide and Conquer
Now for the main event! How you divide depends on the plant’s root system:
- Clumps with Fibrous Roots (like Hostas, Daylilies): These often pull apart relatively easily.
- Shake or hose off some excess soil so you can see what you’re doing.
- Look for natural division points.
- Try inserting two garden forks back-to-back into the center of the clump and prying them apart. Work your way around if needed.
- You can also use a sharp spade or knife to cut through denser clumps. Aim for clean cuts.
- Tough, Woody Crowns (like Peonies, some Astilbe): These require more surgical precision.
- Use a sharp, clean knife to cut the crown into sections.
- Crucial: Make sure each division has at least 3-5 ‘eyes’ (the little reddish buds that will become next year’s stems) and a healthy portion of roots. For peonies, less than 3 eyes might delay flowering.
- Spreading Roots (like Bee Balm, some Phlox): These often form a network. You can usually just dig up sections from the outer edges, which are the most vigorous, or lift the whole clump and separate pieces with healthy roots and top growth shoots.
General Dividing Tips:
- Aim for Healthy Pieces: Each new division should have a good balance of roots and potential growing points (buds or shoots).
- Discard the Bad Bits: Cut away any old, woody centers or diseased/rotted parts. Be ruthless – you only want healthy material.
- Keep Roots Moist: Don’t let the divisions sit out in the sun and wind to dry out while you work. Keep them shaded and mist them with water if needed.
Step 4: Home Sweet New Home
Don’t just jam those divisions back into the ground! Give them the best possible fresh start. This is where good soil preparation is non-negotiable, especially dealing with the heavy clay common in many Ottawa neighbourhoods like Barrhaven or Nepean.
- Dig a Generous Hole: Make the new hole wider than the root mass of your division, and about the same depth.
- Amend, Amend, Amend!: This is vital for clay soil. Mix a generous amount of compost or other well-rotted organic matter into the soil you removed from the hole. This improves drainage (stops roots sitting in water) and aeration (lets roots breathe). Clay holds nutrients well, but it needs organic matter to improve its structure for happy roots. Good soil is the foundation of good gardening.
- Break up the Sides: Loosen the soil on the sides and bottom of the hole with your spade or fork so roots can easily penetrate outwards.
Step 5: Tuck Them In
Almost there! Time to plant your lovely new divisions.
- Depth Matters: Place the division in the center of the prepared hole. The ‘crown’ of the plant (where the stems meet the roots) should sit at the same level it was originally growing. Planting too deep is a common mistake and can lead to rot. Planting too high can expose the roots.
- Fill ‘er Up: Gently backfill the hole with your amended soil, working it around the roots to eliminate large air pockets.
- Firm Gently: Lightly tamp the soil around the base of the plant with your hands. Don’t stomp it down like you’re packing concrete!
- Spacing: Consider the mature size of the plant when deciding where to place your divisions. Give them room to grow! Think of each division as getting its own mini new garden installation – give it the best start!
Step 6: Water, Water Everywhere
Your divisions are thirsty after all that excitement!
- Water Deeply: Immediately after planting, water each division thoroughly. You want the water to soak deep down, encouraging roots to grow downwards.
- Keep Moist: Continue to water regularly, keeping the soil consistently moist (but not waterlogged) until the ground freezes. Fall rains help, but don’t rely on them solely. This is the most critical factor for survival over winter.
- Mulch Later: Apply a layer of mulch (like shredded bark or straw) after the ground begins to freeze. Mulching too early can keep the ground soggy. The goal of fall mulch is to keep the ground frozen and prevent frost heave (where the freeze-thaw cycle pushes plants out of the ground).
Bonus Tips & Tidying Up
- Label Your Work: If you divided multiple types of plants, label your new divisions! You’ll thank yourself next spring.
- Share the Wealth: Got more divisions than space? Offer them to friends, neighbours, or look for local plant swaps!
- Clean Up Crew: This process can generate a fair bit of plant debris and displaced soil. Tidying up your garden beds afterwards is important. If you’re tackling a large project, remember that professional cleanup help is available, whether you need a general Ottawa garden clean up service or something more specific to areas like Marionville, such as the dedicated Marionville property cleanup service.
While we’re happy to share our gardening tips, remember that every garden is unique, and sometimes hands-on help makes all the difference in larger landscaping projects. If you choose to use professional services, including ours, always ensure you’re comfortable with their operational details, typically found in sections like a company’s Privacy Policy and Terms and Conditions, before work begins.
There you have it! Follow these steps, and you’ll be dividing perennials like a seasoned pro, ensuring healthier plants and more blooms for years to come. Happy dividing!
Tucking Them In: Planting and Winter Care for Ottawa Conditions
Okay, team, you’ve bravely divided your perennials – give yourselves a pat on the back! Now comes the equally important part: tucking those new plant babies (and the refreshed originals) snugly into bed for their long winter nap. Getting the planting and winter care right is crucial for survival, especially with Ottawa’s frosty reputation. Think of it as giving them a cozy duvet and a goodnight kiss before the snow flies.
Planting Perfect: Depth and Drainage are Key
We touched on this in the ‘How-To’ section, but it bears repeating because it’s that important:
- Right Height Planting: Remember Goldilocks? Not too deep, not too shallow, but just right. Plant your divisions so the crown (where the stems meet the roots) sits at the exact same level it was growing before. Burying it too deep invites rot, especially over a wet winter. Planting too high exposes the crown and roots to harsh winds and freezing temperatures.
- Drainage, Drainage, Drainage! This is non-negotiable, especially if you’re gardening in areas with heavy clay soil, common around places like Barrhaven or parts of Nepean. Clay holds water, and while plants need moisture, sitting in icy water all winter is a death sentence for most roots. Amending the planting hole generously with compost improves structure, allowing excess water to drain away while still holding enough moisture. Good drainage prevents soggy, frozen roots and helps avoid root rot come springtime.
Water Wisely Until the Freeze
Think of your newly planted divisions like marathon runners crossing the finish line – they’re thirsty!
- Deep Drink After Planting: Give them a thorough soaking right after planting to settle the soil around the roots and eliminate air pockets.
- Consistent Moisture: This is the critical part. Keep the soil around your new divisions consistently moist (like a wrung-out sponge, not a swamp) right up until the ground freezes solid. Check every few days, especially if fall rains are scarce. Even though the tops might be dying back, those roots are working hard underground to establish themselves. Don’t let them dry out!
The Magic of Mulch: Benefits for Winter Protection
Mulching in the fall isn’t about keeping plants warm, surprisingly! In Ottawa, its main job is to keep the ground frozen. Sounds weird, right? But here’s why it’s vital landscaping practice:
- Preventing Frost Heave: Our winters often feature annoying freeze-thaw cycles. When the ground freezes, then thaws slightly, then refreezes hard, it can literally push shallow-rooted plants (like new divisions!) right out of the ground. This exposes their delicate roots to deadly cold and drying winds.
- Consistent Temperature: A layer of mulch acts like insulation, moderating soil temperature fluctuations. It helps keep the ground frozen once it freezes, preventing the damaging heave-ho cycle.
- When to Mulch: Timing is crucial! Wait until after the ground has started to freeze, usually sometime in late November or early December in Ottawa. Mulching too early, while the ground is still warm and potentially wet, can trap excess moisture around the plant crown, leading to rot, and might even provide a cozy winter home for voles or mice (not the tenants you want!). Before applying mulch, ensure the area is clear of excessive leaf debris, especially right around the plant stems; if fall tasks are piling up, remember options like a professional Ottawa garden clean up service can help get your beds ready. Proper cleanup is needed across the region, whether you’re downtown or require assistance further afield, like with a Marionville yard cleanup service.
- How Much Mulch: Apply about 2-4 inches (5-10 cm) of loose mulch over the soil around the plant, but do not pile it directly against the stems or crown. Leave a little breathing room right at the base to prevent moisture buildup and potential rot.
Choosing Your Winter Blanket: Types of Mulch
Plenty of materials make good winter mulch:
- Shredded Leaves: Free and readily available! Run your lawnmower over dry leaves to chop them up. Avoid thick, whole leaves like maple, as they can mat down and suffocate the soil. Oak leaves are great as they don’t compact as easily.
- Straw: Clean straw (not hay, which contains weed seeds) is light, airy, and insulates well.
- Shredded Bark or Wood Chips: These look tidy and break down slowly, adding organic matter over time.
- Evergreen Boughs: Cut branches from your Christmas tree (after the holidays!) or other prunings make excellent, airy insulation.
A Little Extra TLC (Optional Winter Protection)
For most hardy perennials divided correctly and mulched properly, the above steps are sufficient. However, for borderline hardy plants, brand new tiny divisions, or plants in particularly exposed, windy locations (perhaps on a rural property near Richmond or Osgoode), you might consider extra protection:
- Snow Cover: Nature’s best insulator! Encourage snow to accumulate over your beds (a snow fence upwind can help). Don’t pile salty snow from driveways onto your garden beds, though!
- Burlap Wraps or Screens: For sensitive shrubs or small trees, a burlap screen on the windward side can reduce windburn. Ensure it doesn’t trap moisture.
- Rose Cones (Use with Caution): Sometimes used for tender roses, but ensure good ventilation to prevent moisture buildup and disease. Often, mounding soil or compost around the base after the ground freezes is a better option for roses.
Proper fall planting and winter care are essential components of ongoing garden maintenance in our challenging climate. It sets the stage for vigorous growth and beautiful blooms next spring. Planning these tasks, or perhaps scheduling professional help for larger landscaping jobs, can make the season less stressful. If you’re an existing client needing to adjust your service schedule, you can easily do so via the customer portal. And if you’re seeking help, always look for clear communication; getting a detailed quote is important, and providing feedback ensures everyone is on the same page – we even welcome direct comments through our estimate feedback form.
By tucking your perennial divisions in properly, you’re giving them the best chance to survive Ottawa’s winter and thrive for years to come. Sweet dreams, little plants!
Kenmore Gardener’s Cheat Sheet: Quick Fall Division Wins
Okay, Kenmore green thumbs (and fellow Ottawa area gardeners!), feeling the fall frenzy? Dividing perennials doesn’t have to be another chore to dread. Think of it as setting up next year’s garden party! Here’s your quick cheat sheet for getting those fall division wins without the headache.
- Timing is Key (The Sweet Spot): Aim for September to mid-October in the Ottawa region. This gives roots time to settle before the ground freezes solid (usually Nov). Cooler air + warm soil = happy plants.
- Pick Your Players Wisely: Focus on spring/early summer bloomers. Good fall candidates include:
- Hostas
- Daylilies
- Peonies (do these only in fall!)
- Bearded Iris
- Astilbe
- Garden Phlox
- Wait until spring for grasses, mums, asters, and late bloomers like Sedum ‘Autumn Joy’.
- Prep is Everything: Water the plant well a day or two before digging. Have your sharp spade, garden forks, knife, tarp, and compost ready. Sharp tools make cleaner cuts!
- Lift & Split Gently: Dig wide around the plant to get a good root ball. Lift carefully. Use forks back-to-back or a sharp knife to separate the clump into divisions, ensuring each piece has healthy roots and buds (‘eyes’). Toss the dead centre part.
- Plant Like You Mean It: Replant divisions immediately at the same depth they were originally growing. Amend the planting hole soil generously with compost, especially in clay-heavy areas like parts of Nepean or Greely. Good drainage is crucial!
- Water, Water, Water: Soak new divisions thoroughly right after planting. Keep the soil consistently moist (but not soggy!) until the ground freezes hard. This is the most critical step for winter survival.
- Mulch After Freeze-Up: Apply 2-4 inches of loose mulch (shredded leaves, straw, bark) after the ground starts to freeze (late Nov/early Dec). Keep mulch away from the plant crown to prevent rot. This prevents frost heave.
- Tidy Up Time: Dividing can make a bit of a mess! Rake up excess soil and plant debris. Keeping garden beds tidy helps prevent pests and diseases. If the whole fall cleanup seems like too much alongside dividing, remember specialized help is available, whether it’s focused like the Metcalf Garden Clean Up Service or the Marionville Garden Clean Up Service, or a broader approach like a full Metcalf property cleanup service.
- Focus Your Energy: Remember, fall division is for your garden beds. Don’t forget that your lawn has different needs this time of year, requiring specific expert lawn care strategies to prepare it for winter too.
FAQs: Your Ottawa & Kenmore Perennial Division Questions
Uh oh! Generally, you want divisions planted by mid-October for good root growth before the Ottawa freeze. Doing it very late is risky as roots won’t have time to establish. If you absolutely must, mulch very heavily after the ground freezes. If you missed the boat, maybe focus on other fall tasks – sometimes an overall Ottawa yard cleanup service can help get things shipshape for winter instead.
Look for tell-tale signs! Is the centre of the clump looking dead, bare, or weak? Are the flowers smaller than they used to be, or fewer in number? Does the plant flop open unattractively? Or is it simply outgrowing its space? These often mean it’s time to rejuvenate! Check out some garden revitalization transformations to see the amazing difference healthy, well-maintained plants make.
Absolutely! Heavy clay holds moisture, which can lead to root rot over our wet winters and springs. When replanting, dig a wider hole and mix lots of compost into the soil you removed. This improves drainage and adds air pockets. Choosing the right amendments is crucial; you can explore options for soil amendment material selection to combat that sticky clay.
What a great “problem” – sharing the plant love is wonderful! Offer your extra divisions to neighbours, friends, or family. You can also post them (often for free or trade) on local Ottawa gardening Facebook groups or community pages. It’s a fantastic, budget-friendly way to beautify the community. Thanks for thinking green and sharing!
Take a deep breath – you can do it! Peonies are best divided only in the fall. Use a clean, sharp knife to cut the woody crown, ensuring each piece has 3-5 reddish ‘eyes’ (buds) and healthy roots. Replant them quite shallowly, with the eyes just an inch or two below the soil surface. Planting too deep is the main reason they fail to bloom after dividing.
Ha! Good question, but nope, those are definitely separate jobs! Dividing perennials is fantastic for rejuvenating your garden beds and keeping those plants healthy. Lawn care involves totally different tasks like aeration, fertilizing, overseeding, or even considering professional sod installation if your grass needs a major overhaul. Think flowers vs. turf!
Conclusion: Set Up Your Spring Success Story This Fall!
So there you have it – the inside dirt on fall perennial division! It might seem like just one more gardening task before the snow flies, but tackling this in September or early October truly sets your Ottawa garden up for a spectacular spring show.
