At last! It is time to start gardening in Calgary! Well, at least time to start getting ready to garden…! Depending on how much snow we get this month, some of April’s tasks may not be do-able until the end of the month, but here’s my garden to-do list, in order of priority, and modified from the Calgary Horticultural Society’s monthly to do list for April. For some descriptions of what was happening in my garden last April (a verrrry late spring), click here.

What is hardening off?
Early April:
· Start seeds of fast-growing annuals. This year I am growing cosmos, lavatera, cleome, purple millet, and euphorbia ‘snow on the mountain’. Most of these could be direct-seeded outside in May but I like to start them inside for earlier blooms.
· Care for seeds already started in March. This means keeping them under fluorescent lights which are only an inch above the leaves, cutting them back to the first set of leaves to encourage branching, thinning, repotting and fertilizing. I also have an electric fan blowing on my seedlings to help them develop strong, sturdy stems.
Clean and fill bird baths (as soon as weather permits.)
Mid-April
· Take the kids to the garden center, let them pick out their favourite pansies, come home and help them pot them up. Put the pots on the front and back steps… because the pansies can take our spring temperatures and because it’s time for some colour out there, dammit!
Whenever I get the chance:
· Pick up thawed dog poop. Ewww.
· Finishing pruning trees and shrubs except birches, maples, roses and spring-flowering shrubs like lilacs.
· Clean out the “greenhouse” (actually, it’s more like a shed in my case).
· Sweep patios (mine get covered with spruce needles and cones over the winter – what I collect gets put in other areas of the garden as mulch).
· Rake debris from the lawn when it is dry enough to walk on (wet soil gets compacted and that’s a bad thing).
· Cut down any of last year’s perennials that are still standing as soon as ground is dry.
· Start pulling back winter mulch (leaves, in my case) from the crowns of growing perennials – but don’t actually remove it until May. This way the sleeping ladybugs don’t get disturbed too early, and the garden is still somewhat protected from the crazy temperature swings that we will inevitably get!!
Late April:
· Start seeds of the fastest growing annuals: sweet peas, nasturtiums, sunflowers and morning glory.
Set up rain barrels and check eavestroughs.
