We love choosing what bulbs to plant in autumn—there’s something exciting about designing your spring garden and waiting for all those colourful flowers to emerge at the first signs of warmer weather. But have you ever wondered why bulbs need to be planted so many months in advance?

Planting flower bulbs at the wrong time can stunt their growth or inhibit blooming altogether, so understanding the science behind it can help to ensure your spring garden is successful. Here’s a breakdown of why spring-flowering bulbs need to stay in the ground over the winter, and how to get the best results from planting.

When Should I Plant Spring-Blooming Bulbs?

Flower bulbs that bloom in spring are naturally accustomed to staying in the ground over the winter. This cold period is essential to kickstarting their bloom cycle—the cold is like a period of hibernation, and once the temperature begins to rise, this signals to the bulb that it’s time to start growing! Without the transition from cold to warm, your flower bulbs will get confused and won’t develop properly.

While the bulb is hanging out in the soil for several months, this also gives them an opportunity to soak up tons of nutrients from the soil, so they’re ready to spring into action as soon as it’s warm out. This is why it’s always a good idea to mix in lots of compost and remove any weeds from the soil, so your bulbs take in all that extra good stuff, and the weeds won’t end up hogging all the resources.

Ideally, you’ll want to plant your bulbs about 6 weeks before the ground is about to freeze up. Since our weather can be a bit unpredictable in autumn, wait until the temperatures consistently hover around 5-10°C. These are comfortable conditions for your flower bulbs to go in the ground.

Tips for Planting Flower Bulbs

There’s a bit more to planting flower bulbs than simply digging a hole and tossing them in, so follow these basic guidelines to make sure they’re planted properly:

• Choose a spot that gets at least 6 hours of direct sunlight every day. This will help your flowers bloom brightly.
• Plant them with the pointy side facing upward.
• Check the directions on the packaging to see the correct planting depth. Planting them too deeply can result in lots of leaves, but no flowers. Smaller bulbs usually only need to be planted about 4 inches deep, but larger bulbs like daffodils may need closer to 6–8 inches.
• Consider applying a layer of mulch to help block out weeds and regulate the soil temperature.
• Don’t add any fertilizer to the soil until spring, when you see the first signs of sprouting. Fertilizer just confuses plants in the fall and winter while they’re supposed to be resting, so hold off on using any and just stick with compost for building up soil nutrients.

Planting new trees into the landscape is always a worthwhile investment! Not only are they pretty to look at and provide cool shade on hot days, but they add a pretty significant increase in property value. Watching trees transition through each season is always a delight, but trees in autumn are especially beautiful. But did you know that autumn is actuaslly the perfect time to plant many of our favourite trees?

The root ball of a tree is quite sensitive. After all, it acts like their “brain” or central nervous system, so if you stress those roots out too much, you’re going to have a very tired looking tree on your hands. Here in Southern Ontario, if you plant in late spring or in the middle of summer, those high temperatures may be a bit too much for the roots to handle. The cool, mild temperatures of autumn are just right for transplanting.

6 Trees You Can Plant In Fall

Want to liven up your landscape with some colourful foliage? These ornamental trees for fall are so distinctly beautiful in their own different ways—it’s hard to pick just one!  

Tulip Tree

This tree has so much style, and it grows surprisingly quickly, so if you’re a bit of an impatient gardener, you’ll love watching the tulip tree develop over the years. It gets its name from its gorgeous spring flowers, which you probably have guessed, look quite similar to the classic tulip! While it puts on quite a show in spring, it has a reputation for being especially beautiful in fall, when its sunny golden foliage turns a fiery orange shade.  

Because the tulip tree grows so quickly, its branches tend to be a bit thin, so you may want to put it in a spot that gets some protection from the wind. Just make sure it gets at least some partial sun and isn’t too shaded, or else its leaves may turn brown. Regular pruning of your tulip tree and cleanup of any damaged branches will help keep things neat and help prevent pests from showing up.

Autumn Blaze Maple 

There’s something so charming about a giant maple, and the blazing red leaves of this maple tree in autumn look so classically Canadian! It’s a perennial favourite, because it’s actually a cross between the red maple and the silver maple, and it seems to have taken on the best traits of both. Overall, it has stunning colours, a nice, balanced branching habit, and pretty sturdy limbs despite being a very fast grower.

Autumn blaze maples need full sun to grow to their best potential, but the condition of the soil is much less critical. This variety is actually quite drought tolerant and doesn’t mind poorer soils—just be sure you water it very regularly for those first couple of months after planting to help the roots establish. 

Eastern Redbud

You’ll always look forward to spring in your yard with this show-stopping beauty around! It bursts into bright magenta blossoms and looks like it’s straight off the pages of a fairytale book. They don’t grow especially big—about 30 feet tall and wide at its largest—so if you’re looking for something a little smaller scale, the eastern redbud will suit the landscape nicely.

 Ideally, you’ll want to plant your tree in a spot that gets direct sunlight in the morning, but a bit of shade in the afternoon, so a North or East-facing spot in the yard would work best. Plant it at least 8 feet away from any buildings to give it adequate room to spread, and try to put it in a spot that isn’t at the bottom of any slopes. This could cause too much moisture to collect near its roots, and this tree doesn’t like to sit in soggy soil. So long as the soil is quick-draining and isn’t piled up around the trunk of the tree, you aren’t likely to encounter any problems.  

Emerald Cedar

We had to add a nice evergreen into the mix! Having vibrant foliage to admire year-round is always such a treat. This narrow variety is upright and handsome, reaching around 12 feet at maturity, so it’s super easy to integrate into the landscape and works particularly well as a hedge border. Its emerald green foliage is finely textured and lush all year long; it’s so classically refined!

This evergreen prefers full to partial sun. It likes well-drained soils, but isn’t very drought-tolerant and prefers moderate moisture, so if we go through a long stretch without rain, you’ll definitely want to water the roots with the hose to keep conditions comfortable. You aren’t likely to have too many pests issues with the emerald cedar, but in December, you may want to wrap it up with burlap to prevent the foliage from getting winter burn. 

Heritage Birch

The bark of the birch tree is so uniquely beautiful and textured—we love the way it naturally peels off like paper, revealing fresh new bark underneath. The mature bark of the heritage birch almost has a pinkish tint to it, revealing creamy white new growth underneath. Growing up to around 70 feet tall and wide, it’s quite a sight to behold when grown with multiple trunks, instead of being trained into a single-trunked tree. 

The heritage birch actually prefers its soil to be a bit more on the moist side and is more tolerant of clay soils compared to many other common landscape trees. It’s also quite heat tolerant, so as long as it gets some extra water, it shouldn’t be too fazed by a summer heatwave. If you’re going to prune your heritage birch, wait until fall to do so—in spring, the sap is a lot runnier and will make quite a mess!

Autumn Brilliance Serviceberry

This compact tree loves to show off its personality, covered with pretty white flowers every spring, and outdoing itself with orangey-red fall foliage. It produces berries from late spring and into summer, and it has smooth grayish-silver bark. It’s a nice small tree at just 25 feet maximum height. This is a great shade choice for small-scale landscapes. This serviceberry is suitable for planting under power lines. 

Serviceberries grow best in full to part sun, and should not be allowed to dry out. This serviceberry is relatively low maintenance, and a beautiful addition to any yard.
