Little gardeners welcome: Start a family-friendly container garden

When you picture a vegetable garden, you might imagine a big backyard with neat rows and wooden fences. But don’t let limited space stop you! Even if you only have a balcony or a sunny patch of concrete, you can grow delicious vegetables without a backyard.

\n \n

Container gardening is a fun, low-maintenance way to grow your own food. It's especially great for families, helping kids learn where their food comes from while enjoying the satisfaction of growing something themselves. Best of all, you don’t need fancy tools. All you need are containers, soil, water, and sunshine.

\n

Start simple with peas and lettuce. If you’re new to gardening, start with easy crops like peas and lettuce. They grow quickly, don’t need deep containers, and love Calgary’s cool spring and fall weather. They’re also fun and fast for kids to harvest.

\n

Choose the right containers. Size matters. Plants need enough room for their roots to grow and for soil to hold moisture. 

\n

Here’s a quick guide:

\n
    \n
  • 5-gallon containers: Tomatoes, peppers, cucumbers, beans
  • \n
  • 3-gallon containers: Carrots, lettuce, beets, green onions
  • \n
  • 1-gallon or less: Herbs and radishes
  • \n
\n

You don’t have to buy fancy pots. Try wooden boxes, plastic bins, or even an old laundry basket. Just be sure your container has drainage holes to prevent root rot. Avoid dark or metal containers, as they can overheat on sunny days.

\n

Kid tip: Let kids decorate containers with paint or markers before planting.

\n

Use good soil and drain well. Skip digging up your yard. Garden soil is too dense for containers. Use a high-quality potting mix made for containers, which holds moisture while still draining well. This is especially important in Calgary’s dry climate.

\n

To improve drainage:

\n
    \n
  • Ensure each pot has holes in the bottom
  • \n
  • Cover holes with mesh or a coffee filter to keep soil from spilling out
  • \n
  • Raise containers slightly off the ground using bricks, pot feet, or rocks
  • \n
\n

Pick the right spot. Most vegetables need at least six hours of sunlight each day. Calgary’s sun is strong but not always consistent, so check your space throughout the day. Move containers to follow the sun if needed.

\n

Vegetables also prefer warm soil, ideally above 15 degrees Celsius. Wait until late spring before placing your plants outside full-time.

\n

Water smart. Containers dry out faster than in-ground gardens. During hot summer days, you may need to water daily or even twice a day. Stick your finger about an inch into the soil. If it’s dry, water. If it’s still moist, wait. Busy family? Consider using self-watering containers. They make it easier to keep up with watering, especially during hot weather or weekend trips.

\n

Feed your food. Container soil doesn't hold nutrients long-term. Mix in a slow-release fertilizer when planting. Every couple of weeks, give your plants a boost with diluted fish emulsion or liquid seaweed. Compost also adds helpful nutrients if you have it.

\n

Seeds or seedlings?

\n

Starting from seed is less expensive and gives you more variety, but it takes time and care. If you're short on time or energy and want to skip to the good part, pick up seedlings from a local garden centre. Whether you grow from seed or buy seedlings, remember to harden off young plants by gradually introducing them to outdoor conditions before planting them permanently.

Best veggies (and fruit!) for Calgary container gardens

\n

These plants grow well in containers and can handle Calgary’s climate:

\n
    \n
  • Leafy greens: Grow fast, tolerate some shade, and can be harvested more than once
  • \n
  • Peas: Love cool weather and grow well with a small trellis
  • \n
  • Radishes: Quick to grow and great for kids
  • \n
  • Carrots: Use deep containers and enjoy pulling them up at harvest
  • \n
  • Tomatoes and peppers: Need full sun and support cages
  • \n
  • Zucchini and cucumbers: Pick bush varieties and give them support to climb
  • \n
  • Potatoes: Use large buckets or grow bags (fun for kids to dig up)
  • \n
  • Strawberries: Easy to grow in containers or hanging baskets. They like full sun and produce sweet fruit all summer long
  • \n
\n

Why try it?

\n

Container gardening is more than just a way to grow food. It helps families connect with nature, slow down, and enjoy time together. It teaches kids about responsibility and where their food comes from, all while creating something delicious and rewarding.

\n

Final tip: Calgary’s weather can be unpredictable. Be ready to cover your plants or move containers if a cold snap hits, even in late spring.

\n

Happy planting!
