As the days grow shorter and the air crisper, it's time to start preparing your garden for the colder months. You would think the garden season is winding down, but there are still some essential things to do before winter takes our oh-so-beloved outdoor activity away from us. Fall is not only a season of transition but also an important time to clean up your garden and plant fall bulbs that will bloom into a beautiful display next spring. Whether you’re in the temperate coastal regions or the chillier northern climates of Canada, this guide will help you plan and execute your fall garden tasks at just the right time.
Gardening across Canada means that timing for fall cleanup can vary depending on your location.
Coastal and Mild Zones (e.g., Lower Mainland BC, Vancouver Island, southern Ontario): In these milder areas, fall cleanup can wait until later in October or even November. Frost may come late, so you have extra time to enjoy fall blooms and let your plants finish their life cycle naturally. Start by cutting back perennials, removing spent annuals, and cleaning up fallen leaves to prevent diseases and pests from overwintering in your garden. Some leaves, depending on where you have them, can act as a nice warm blanket and protection for your plants.
Cooler Zones (e.g., interior BC, Alberta, Manitoba, and parts of Quebec)
In cooler regions, it’s important to begin your fall cleanup by mid-October. You’ll want to clean up plant debris and prune dead or diseased branches before the first hard frost. This is also the time to divide overcrowded perennials, mulch garden beds, and prepare your soil for the winter ahead.
Colder and Northern Zones (e.g., northern Alberta, Saskatchewan, and the northern Territories)
Frosts come earlier here, so fall cleanup is most likely already in full swing where you are. Make sure to remove any diseased plants and tidy up the garden before the ground freezes. Covering the soil with mulch can help protect it from the harsh winter temperatures, keeping the soil insulated.
When is the Right Time to Plant Fall Bulbs?
One of the most exciting parts of fall is planting spring-flowering bulbs like tulips, daffodils, crocuses, hyacinths and alliums. The key to success is planting them when the soil temperature is right, generally between 10°C and 15°C.
Mild and Coastal Zones
You can plant bulbs later here, often as late as November. In areas where the ground doesn’t freeze until late in the year, you can wait for the first frost to plant your bulbs, giving them the cool temperature they need to set roots. I am often very late with planting my bulbs as I am just too busy shipping out all the orders to our dear customers.
Cooler Zones
In cooler regions, aim to plant your bulbs in October. The soil temperature will be cool enough for bulbs to establish roots before winter arrives. Be sure to plant them deep enough (usually about three times the height of the bulb) to protect them from freeze-thaw cycles.
Colder and Northern Zones
In these regions, bulbs should go in the ground by mid-September to early October, before the soil freezes. It’s essential to plant bulbs early enough to allow them time to develop strong roots but late enough that they don’t sprout prematurely.
Regardless of your climate zone, here are some general tips to ensure your bulbs bloom beautifully in spring: Choose Quality Bulbs! With Botanus you will be in good hands when it comes to quality and service!! Always start with healthy, firm bulbs and make sure to get the top size for each variety unless you do mass plantings and it is more about the quantity that makes the wow effect.
Prepare the Soil! Well-drained soil is key to preventing bulbs from rotting over winter. If your garden soil tends to be heavy or clay-like, mix in organic matter like compost to improve drainage.
Plant at the Right Depth! As a general rule, plant bulbs are about three times as deep as the bulb is tall. This helps protect them from the winter cold and prevents squirrels or other animals from digging them up.
Mark Your Plantings! It’s easy to forget where bulbs are planted, so marking the area with stakes or small flags will help you avoid disturbing them later in the season. For extra protection mulch your garden beds.
A layer of mulch not only insulates the soil but also helps retain moisture and prevent weeds. In colder zones, apply a thicker layer to protect plant roots from extreme winter temperatures.
And after all the clean up and planting is done we need to take care of our tools. Take the time to clean and sharpen your gardening tools ... you will be thankful you did it when you take them out in the spring and they are ready to go. Store hoses, pots, and other garden equipment in a dry space to prevent damage from frost.
Fall is your garden’s time to rest and rejuvenate, and by taking the right steps now, you’re setting yourself up for a glorious spring bloom. Whether you’re in a mild coastal zone or a colder northern region, planning your fall cleanup and bulb planting according to your climate will ensure your garden is healthy, vibrant, and ready to burst into life when the snow melts.
