What to Plant in September: Trees, Shrubs, and Perennials for Fall Success

Did you know the Fall is an ideal time to plant? With cooler temperatures and increased rainfall, the soil stays moist, and plants have plenty of time to establish strong root systems before winter sets in. If you're thinking about adding new trees, shrubs, or perennials to your garden, September is the perfect month to get started!

Here are some excellent options for planting in the fall:

Evergreens and Deciduous Trees

September is an excellent time for planting trees! The trees and shrubs that hold their leaves all year and provide colour and interest, even in the coldest season, will have time to establish their roots and get a head start in the spring!

  • Japanese Waterfall Maple: The beautiful, finely cut foliage of this small tree will add wonderful texture to beds, foundation plantings and even containers close to your patio or deck.
  • Dogwood: Dogwoods add beauty with their white or pink flowers in spring and vibrant red leaves in the fall. The Pacific Dogwood - a native to British Columbia adds a stunning feature while having great drought tolerance!
  • Korean Silver Fir: With its green needles that curl back to the stem displaying bright silver undersides. Purple Cones appear on young trees.
  • Colorado Blue Spruce: a sturdy and tough tree that tolerates extreme cold, high winds, and heavy snow. Perfect to plant for a privacy screen or a touch of colour with its bright blue-green needles and dense branches.
  • Magnolia Tree: Known for their beautiful blooms in the spring, Magnolia Trees can come in a variety of shapes and colours! 
  • Montrose Charm White Spruce: A fast grower, this tall narrow columnar tree has needles that are light green and very short. Once established, it is cold-hardy and drought resistant. This columnar tree is perfect for landscaping, borders, small spaces, and erosion control.

Why Fall Planting Works

The key to fall planting success is the moderate weather, which allows plants to focus on root development rather than top growth. With more consistent rainfall, you can expect less watering compared to summer planting, and the cooler days reduce the risk of transplant shock. Fall planting allows just enough time for the roots of a plant to become established before winter. And that acclimation period is extremely important! Planting in the fall has built-in advantages for establishing young plants as well. Autumn’s cooler temperatures, along with its shorter daylight cycles help trees and shrubs acclimate with less stress. With less heat, drying winds and less hours of sun, their root system is much more likely to keep up, and less likely to dry out as well. Less watering needed and less stress. Roots continue to grow until the deep freeze comes. But they also start growing in very early spring when the ground thaws before their new leaves burst forth! In essence, a fall planting sets the stage for a tree, shrub or perennial to be ready for fast growth the following spring. And more importantly, not have to spend all its resources and efforts on simply surviving!
