Spring Awakening: Getting Your Calgary Garden Ready

Calgary’s springs arrive with mixed weather—sudden warm days followed by sneaky frosts and drying winds. With a little planning, you can give your garden a strong start and make the most of those short growing windows.

1) Do a quick garden health check.

• Clear away remaining debris from last year: fallen leaves, spent stems, and any diseased material.
• Inspect structures: trellises, edging, hoses, and garden tools for winter wear and tear.
• Note what survived the winter and what didn’t, so you can adjust your plan.

2) Test and improve the soil

• If you haven’t tested recently, please get a basic soil test to check pH and nutrients. Calgary soils can vary widely.
• Add compost or well-rotted manure to boost organic matter and soil life. This helps with moisture retention during dry Chinook weather.
• If your soil is heavy clay, mix in some coarse sand or organic matter to improve drainage.

3) Prune and divide with care

• Prune deciduous shrubs and perennials while they’re still dormant, focusing on removing dead or damaged wood.
• Early spring is a good time to divide overgrown perennials (hostas, daylilies, sleutel) before they wake up too vigorously. 
• Clean up woody perennials after pruning to avoid encouraging new growth that could be damaged by late frosts.

4) Mulch and protect plants

• Apply 2–3 inches of mulch around beds to conserve moisture, suppress weeds, and stabilize soil temperature.
• Use a light mulch layer over tender seedlings if a late frost threatens, and uncover on milder days.

5) Lawns: wake up and welcome spring

• Rake out dead grass and moss, then overseed bare patches if needed.
• Consider a light top-dress with compost to improve soil fertility and help drought resilience.
• Avoid heavy fertilizers too early; Calgary lawns benefit from a slow, balanced feed once the soil has thawed and warmed.

6) Plan for frost risk and timing

• Calgary’s last frost can still surprise you into May. Keep hardy seeds and transplants—such as peas, spinach, radishes, lettuce, and kale—on the ready in protected spots or started indoors.
• Start warm-season crops only after soil temps reliably rise, and danger of frost has passed; use season extenders like cloches, row covers, or a cold frame if you’re eager to get an early start.

7) Start a few cool-season crops

• Plant cool-tolerant greens, root crops, and brassicas as soon as the soil can be worked.
• Direct-sow carrots, beets, and radishes, or transplant broccoli and cauliflower starts once the ground has dried enough to work.

8) Water wisely

• Calgary summers can be dry and windy. Install a simple drip irrigation or soaker hose setup to keep water where it’s needed.
• Water deeply but infrequently to encourage deep roots. Early-morning watering helps reduce evaporation and disease.

9) Consider natives and drought-tolerant plants

• Native grasses, wildflowers, and hardy perennials often resist Calgary’s wind, cold snaps, and drought better than delicate ornamentals.
• Plan a pollinator-friendly corner with a mix of native plants and a few well-chosen ornamentals to keep blooms coming through spring and summer.

A quick Calgary spring garden checklist

• Clear debris, inspect tools and beds

• Soil test and amend with compost

• Prune, divide, and clean up perennials

• Mulch beds and protect tender plants

• Rake lawns, over seed patches, and fertilize lightly

• Start cool-season crops; hold off warm-season crops

• Install irrigation and practice deep watering

• Consider native and drought-tolerant plants
