Preseason Prep: Setting the Stage for Success 

Alright, let's get this gardening party started even before we touch the soil! Preseason prep is like the backstage magic that sets the stage for a show stopping garden!

  • Sparkle Time for Your Tools! First things first, let's give our trusty gardening tools some love! Cleaning and sharpening your trowel or hoe will make digging and weeding feel like a breeze! And don't forget to ensure those shears are spick-and-span and ready for action.

  • Hose and Watering Can Check Up! Time to play detective! Let's thoroughly inspect those hoses, irrigation systems, and watering cans for any sneaky leaks or cracks. Catching these early means we'll be fully prepared when the season kicks off and not waste a single drop!

  • Garden Bed Reconnaissance Mission! Let's take a stroll around our beloved garden beds and be on the lookout for any signs of winter's frosty farewell, like frost heaved soil or even broken fences.

  • Soil Spa Day! How's our soil feeling after its winter slumber? Let's check its condition – is it looking a bit compacted or perhaps longing for some enriching goodness? We might need to treat it to some compost, organic matter, or even a cozy blanket of mulch to boost its structure and drainage!

  • Dream It, Plan It, Grow It! Now for the fun part – let your imagination run wild! Think about what you want to grow this year. Maybe it's time to try your hand at a vibrant vegetable patch or welcome some buzzing pollinators with a burst of new flowers!

  • Maximize the Magic! Remember, our Calgary growing season is like a fantastic sprint, so let's make every inch count! Map out where everything will go, keeping in mind the genius of companion planting, the sun's loving rays, and the smart strategy of crop rotation if you're growing veggies.


When to Plant: Navigating Calgary's Short Growing Season

Timing is everything, my friends, especially in our Calgary gardening adventure! Knowing the planting sweet spots is absolutely key to a flourishing garden.

  • The Short and Sweet Season: Our growing season is definitely on the shorter side, which makes understanding the right planting windows super important.

  • Indoor Adventures (6-8 weeks before the last frost – mid-May average): Get a head start with those heat loving superstars like tomatoes, peppers, and eggplants by starting them indoors in late February to early March! Even our fragrant friends basil and oregano will thank you for an early indoor boost! And for those gorgeous perennials like lavender or echinacea that need a bit of extra time to get going, start them indoors about 6-8 weeks before that last expected frost.

  • Outdoor Welcomes (After the Last Frost – typically mid-May): Hold your horses, and hoses, for those more sensitive green babies like tomatoes, peppers, and cucumbers until the very real threat of frost has waved goodbye!

  • Direct Sowing Fun (Late April to Early May, depending on soil): Get those cool season champions like carrots, radishes, and beets right into the ground around late April to early May! They're tough cookies and can handle those cooler soil temperatures, even if the weather is still playing coy.

  • Early Bird Planting (Late April to Early May, depending on soil): And for our hardy veggie heroes like lettuce, spinach, and peas, you can usually get them in the ground as early as late April to early May, as long as the soil is playing along!

Choosing the Right Plants for Calgary's Climate

Let's talk about picking the rockstars of the plant world – the ones perfectly suited to our Calgary climate, specifically our hardiness zone!  Choosing plants that can handle our cooler temperatures is a game-changer.

  • Hardy Heroes are the Way to Go! Selecting plants that are well-equipped to withstand our sometimes chilly conditions is crucial for a happy garden.

  • Perennial Powerhouses for Calgary: Get ready to welcome back these beauties year after year! Hostas, daylilies, peonies, and coneflowers are fantastic choices for our colder climate!

  • Veggie Victory with Cold Tolerance: You can absolutely grow delicious veggies here! Look for winners like kale, spinach, peas, and radishes – they thrive in our shorter growing season!

  • Herbs that Hang Tough: Add flavor and fragrance with resilient herbs like thyme, rosemary, mint, and chives. Planting them in a cozy, sheltered spot or even in containers can give them an extra edge against cooler snaps.

Smart Water Management for Calgary Gardens 

Alright, water wise warriors, let's talk about keeping our gardens lush and vibrant while being super smart about our precious water resources in Calgary's often dry climate!

  • Water Wisdom in a Dry Climate: Conserving water isn't just a good idea; it's essential for a thriving Calgary garden.

  • Watering Like a Pro: Forget those daily sprinkles! The secret is to water deeply a couple of times a week – this encourages strong root growth. Remember, Calgary's soil often drains quickly, so deep watering helps.

  • Mulch: Your Garden's Best Friend! Get ready to become besties with mulch! This amazing stuff helps conserve precious moisture, regulates soil temperature, and keeps those pesky weeds at bay. Use organic mulch like wood chips or straw and spread a layer about 2-3 inches thick around your plants.

  • Rain Gardens: Nature's Brilliant Filters! Prepare to be amazed by the magic of rain gardens!

    • What's the Buzz About Rain Gardens? A rain garden is like a beautifully landscaped superhero that collects stormwater (rain and melted snow) running off your yard and driveway. It's a shallow depression filled with loose, deep soil that acts like a natural sponge and filter.

    • How the Magic Happens: When it rains, stormwater is channeled into the rain garden. Then, the amazing combination of plants, layers of soil, and gravel work together to filter and absorb that water. Silt and leaves stay on top, while other pollutants are broken down by the soil and plants.

    • Why Rain Gardens Rock!

      • They are champions at protecting our watershed by managing sediment and pollutants.

      • They help reduce river bank erosion and those annoying localized flooding issues.

      • In areas where big stormwater solutions aren't possible, rain gardens are a fantastic alternative.

      • They're not just functional; they're planted with beautiful, hardy, low-maintenance, and water-wise plants!

      • Get ready for some delightful visitors! Rain gardens attract birds, butterflies, and even mosquito-eating dragonflies!

      • They complement any landscape and boost the beauty of your neighborhood!

      • By capturing runoff, they limit the amount of water rushing into our storm drain systems, further reducing flooding and stream bank erosion.

      • They're amazing at reducing the nasty pollutants that often wash from our yards and roads straight into our precious waterways.

    • No Mosquito Party Here! Don't worry about creating a mosquito haven! Properly built rain gardens drain within 48 hours (usually much faster), which isn't enough time for mosquitoes to breed!

    • Rain Gardens at Home: Imagine a charming, slightly sunken area in your garden, perfectly placed to catch rainwater flowing from your roof! That's a residential rain garden, a shallow depression with loose soil and gorgeous, hardy plants that naturally filter runoff before it hits the stormwater system!

  • Rain Barrels: Catching the Liquid Gold! Get ready to embrace the wonderful world of rain barrels!

    • Wise Water Warriors: Rain barrels are fantastic for using water wisely, helping us reduce our reliance on the city's water supply, especially during those thirsty summer months.

    • Barrel Benefits Galore! Captured rainwater is amazing for keeping your yards and gardens healthy, and it also helps contain water on your property, reduce soil erosion, and stop pollutants from washing into our waterways!

    • The City and Green Calgary to the Rescue! Get this – The City of Calgary has teamed up with Green Calgary to offer a brand-new $50 rebate on up to two rain barrels starting April 1, 2025! This is an incredible opportunity to make water-wise gardening even more accessible!

    • Rebate Details You Need to Know! If you purchase rain barrels from Green Calgary or a local vendor in Calgary after March 31, 2025, you can submit an application with your original receipts and get $50 back per barrel (up to two per household). This awesome program can rebate a maximum of 3,000 rain barrels!

    • Where to Snag Your Rain Barrel! Green Calgary rain barrels are available for pre-order and will cost $75 + GST after the rebate, starting April 1, 2025. You can also find them at these locations on the following dates between 9 a.m. and 1 p.m.:

      • April 19th - IKEA (8000 11 St. S.E.)

Maintaining Your Calgary Garden Throughout the Season

Once we've planted our little green friends, the journey continues with regular care!

  • Consistent Watering is Key: Keep up that deep watering routine a couple of times a week.

  • Mulch Magic Continues: Keep an eye on your mulch layer and replenish it as needed.

  • Frost Patrol! Calgary weather can still surprise us, so be ready to cover your precious plants with frost blankets or old sheets if a late spring or early fall frost is on the way.

  • Herb Happiness: Remember those tender herbs? Giving them a sheltered spot or planting them in containers can really help them thrive in our cooler climate.

Addressing Specific Calgary Gardening Challenges

While we're on a roll, let's tackle some common Calgary gardening hurdles head-on!

  • Taming Calgary's Alkaline Soil: Our soil can sometimes lean towards the alkaline side. Don't worry! We can amend it with things like peat moss or sulfur to gently lower the pH and create a more welcoming environment for our plants.

  • Bouncing Back from Pests and Diseases: Every garden can face unwanted visitors. Let's explore organic and low-impact methods for keeping common Calgary pests and diseases at bay, ensuring our plants stay healthy and happy.

  • Stretching the Season: Who says the gardening fun has to end with the first hint of frost? We can use tools like cold frames or row covers to extend our growing season and enjoy fresh produce and beautiful blooms for longer!

Building a Rain Garden in Calgary: A Step-by-Step Guide 

Ready to dive into the exciting world of rain garden construction? Let's do this! Remember to contact Utility Safety Partners at 1-800-242-3447 or submit a locate request online before you start digging to ensure you don't hit any underground utilities! Safety first!

  • Location, Location, Location! Choose a spot that's a natural low point in your yard where water tends to collect. Make sure it's at least 10 feet away from your house foundation to be extra safe.

  • Sizing it Up: The size of your rain garden will depend on how much water drains into the area and your soil type. There are handy online calculators to help you figure this out!

  • Soil Secrets: Get to know your soil! A simple test can tell you what you're working with. Amending it with lots of organic matter is key for good drainage and filtration.

  • Digging In! Carefully excavate a shallow depression with gently sloping sides. The depth will typically be between 6 and 12 inches in the center.

  • Layering for Success: Create layers within your rain garden to help with drainage and filtration. This often includes a layer of gravel at the bottom, followed by a mix of sand and topsoil.

  • Planting Powerhouses! Select native, water-wise plants that thrive in Calgary and can tolerate both wet and dry conditions. Think about incorporating a variety of plants to attract pollinators and add visual interest! Local nurseries can offer fantastic suggestions.

  • Water Flow Management: Make sure the runoff from your downspouts or low areas is directed right into your new rain garden. You might need to create a slight swale or channel.

  • Welcome Home, Plants! Water your newly planted rain garden regularly for the first few weeks to help them get established.

The Role of Soil Health in Water Management and Plant Growth

Let's dig a little deeper into the amazing world beneath our feet – soil health!

  • Healthy Soil = Happy Plants (and Better Water Management!): Healthy soil acts like a sponge, improving both water retention during dry spells and drainage during heavy rains.

  • Compost is Your Superpower!: Different types of compost offer unique benefits for our Calgary soils, enriching them with nutrients and improving their structure.

  • The Magic of Cover Cropping: Even in small urban gardens, cover cropping can work wonders for improving soil health and water management.

  • Say No to Compaction!: Avoiding walking on wet soil helps maintain its structure and allows for better water infiltration and root growth.

Natural Garden Boosters: Canola Oil's Surprising Gardening Secret!
Did you know that a kitchen staple like canola oil can be a secret weapon in your gardening toolkit? Canola oil is a fantastic eco-friendly option for managing common Calgary garden pests like aphids, mites, and scale insects. Simply mix a teaspoon of canola oil with a quart of water and a few drops of mild dish soap, then spray lightly on affected plants. This safe, natural approach helps protect your garden while keeping it healthy and thriving!

Connecting Water Wise Gardening to Climate Resilience in Calgary

Our individual gardening efforts can have a bigger impact than we think!

  • Rain Gardens: Our Allies Against Intense Rainfall: Rain gardens help manage the increased runoff from more intense rainfall events, reducing the strain on our stormwater systems.

  • Rain Barrels and Efficient Watering: Saving Water When We Need It Most: By capturing rainwater and using water wisely, we're conserving this precious resource during drier periods, contributing to climate resilience.

  • Every Little Bit Helps!: As homeowners, we all have a role to play in adapting to climate change, and water-wise gardening is a fantastic way to contribute!
