Fall Watering Guide: Calgary Edition
A little attention now can make a big difference in spring.
As we settle into cooler weather, watering can feel optional. In Calgary’s dry climate, it is actually one of the most important things you can do before winter arrives.
Roots continue to take up moisture until the ground freezes. Moist soil protects against winter drought, freeze and thaw swings, and the chinook winds that dry everything out faster than you expect.
Extra Care for New Plantings
If you added anything new this year, give it a bit more attention. Calgary’s high elevation, dry air, and gusty winds can stress young roots their first winter.
A few helpful reminders:
Keep watering until the snow sticks around
Slow, deep watering is better than quick surface sprays
Check soil two inches down, since the top layer can look dry even when the ground is moist underneath
Add mulch to help hold moisture and buffer temperature swings
That first winter in Calgary can be tough on new plants. Hydration goes a long way.
Watering Tips for Calgary Gardens
Do not rely on the surface. Our soil crusts and dries quickly in wind
Deep watering encourages roots to grow down, not sideways
During chinooks, soil can thaw on top. Water if the ground is not frozen underneath
Stop once the soil freezes solid, but aim to keep it moist before then
If Your Sprinklers Are Already Off
If your irrigation is winterized, switch to a hose or watering wand during warm periods. Calgary often sees melt days well into November, so plants can still absorb water.
If you water by hand, pay attention to sheltered zones. Shady areas near fences can hold moisture longer, while exposed south and west sides dry out fast.
Before Winter Fully Sets In
Give trees, shrubs, and perennial beds a final deep soak before the first hard frost, usually late October
Disconnect hoses and drain outdoor taps because chinooks can trick lines into expanding and bursting
Shut down irrigation controllers once freeze-up is consistent
Local Notes Worth Knowing
Chinook winds can pull moisture from both soil and needles on evergreens
Calgary’s clay pockets can hold water longer, so check before adding more
Sunny days can trick plants into thinking it is spring. Water helps prevent winter burn
South and west exposures dry out fastest due to sun and wind exposure
Most years, watering can continue into mid or late November based on ground temperature
Why This Matters
Calgary winters bring long dry stretches, sudden warm-ups, and rapid drops in temperature. Without enough moisture in the root zone, plants enter winter stressed and often do not recover well in spring.
A few thoughtful watering sessions this fall can save you time, money, and replanting when the snow melts.
