How to Grow Mint in Canada Without Letting It Take Over Your Garden

 

If you’ve ever tried growing mint in your garden, you’ve probably experienced both its charm and its chaos. This aromatic herb is one of the easiest and fastest to grow—so much so, that it can take over entire beds if not properly managed.

I’m Darrell Smith, owner of DH Garden Centre in Kitsilano, Vancouver, and DH Landscape Solutions. Over the past 25 years working with landscapes and 11 years running the garden centre, I’ve helped hundreds of customers wrangle runaway mint and turn it into a thriving, manageable herb. In this guide, I’ll walk you through everything you need to know about growing mint successfully in Canada—from container choices and soil tips to propagation and winter care.

Why Grow Mint?

Mint is a must-have in any home garden. Here’s why:

• It’s perennial, meaning it comes back every year (with a little care).
• It’s fragrant and freshens up both your garden and your kitchen.
• It’s great for herbal teas, mojitos, salad dressings, pest control, and natural remedies.
• It’s a pollinator magnet—bees and butterflies love it!

But it’s also aggressive. Mint spreads through underground rhizomes that can sneak under fences, crawl across pathways, and pop up in places you never intended. That’s why smart growing techniques are key.

Choosing the Right Mint Varieties

Mint isn’t just one plant—it’s a whole family. Each variety has its own look, scent, and culinary value. Here are some top picks for Canadian gardens:

• Spearmint: Classic, sweet, and perfect for drinks.
• Peppermint: Stronger, menthol-like scent. Excellent for tea.
• Pineapple Mint: Variegated leaves and tropical scent. Eye-catching!
• Chocolate Mint: A dessert lover’s dream. Grows well in partial shade.
• Apple, Orange, and Ginger Mint: Fruity and exotic—great for infusions.

All these varieties thrive in containers or raised beds with partial sun. At DH Garden Centre, we often recommend trying multiple types—but keep them separate to avoid flavor blending.

Ideal Growing Conditions

Mint grows easily in Canada’s climate—especially in Zones 5 through 8. But it still has preferences:

• Light: Partial sun is ideal (4–6 hours/day). Full sun is fine if you water consistently.
• Soil: Rich, well-draining, slightly acidic soil with compost. We recommend our DH Organic Herb Mix.
• Water: Consistent moisture is key. Don’t let the soil dry out. Use mulch to retain water.
• Fertilizer: Monthly light feedings with compost tea or organic fertilizer during growing season.

Containers Are Your Best Friend

To prevent mint from spreading uncontrollably, grow it in containers. Here’s why this works:

• It contains the root system (rhizomes).
• Makes it easy to move indoors in winter.
• Prevents flavor blending when growing multiple types.

Choose a pot at least 12 inches deep with good drainage. You can even bury pots in your garden beds to disguise them while keeping mint roots contained.

🪴 Darrell’s Pro Tip: When potting up nursery mint, go a size or two larger than the original pot and loosen the root ball to encourage outward growth.

Propagation: Multiply Your Mint

Mint propagates like a dream. You can grow more from divisions or cuttings:

Propagation by Division

1. Remove a mature mint plant from its pot.
2. Slice the root ball into halves or quarters with a sharp tool.
3. Replant each section in new containers.

This is perfect for renewing overgrown plants or giving away to friends.

Propagation from Cuttings

1. Snip a 4–6 inch stem below a leaf node.
2. Remove the lower leaves.
3. Place in a jar of water or moist potting soil.
4. Roots appear in 1–2 weeks. Transplant once they’re 1 inch long.

You can also lay mint cuttings horizontally in soil and lightly cover them—roots will sprout from the leaf nodes.

Harvesting and Pruning for Productivity

Regular harvesting is essential. It keeps the plant healthy and stops it from flowering too early (which can reduce leaf quality).

• When to harvest: Late morning, just before the sun peaks. Aromatics are strongest.
• How to harvest: Snip above a leaf node. This encourages bushier growth.
• How often: Every 1–2 weeks during peak season. Never harvest more than one-third at once.

Mint can be pruned like a hedge. Keep it low and bushy instead of letting it grow tall and leggy.

Seasonal Mint Care in Canada

Canada’s climate calls for a seasonal approach:

Spring (April–May)

• Start new plants indoors or outdoors once frost risk is gone.
• Re-pot or divide established plants.
• Feed with compost and top up mulch.

Summer (June–August)

• Water consistently.
• Harvest often.
• Watch for pests like aphids or spider mites—treat with neem oil.

Fall (September–October)

• Heavily prune back and mulch if overwintering outdoors.
• Divide and repot for indoor growing.

Winter (November–March)

• Outdoors: Mulch deeply or move pots to sheltered areas.
• Indoors: Place in a bright window. Water lightly once a week.

Troubleshooting: Common Mint Problems

Even the easiest plants need attention. Here’s what to look out for:

• Yellowing leaves: Overwatering or poor drainage.
• Leggy growth: Not enough light. Move to a sunnier spot.
• Flavorless leaves: Crowded planting or poor soil nutrients.
• Mint rust: Fungal disease. Prune infected parts and avoid overhead watering.

🧪 Darrell’s Note: If flavors seem dull, avoid planting multiple varieties too close together. Some gardeners report flavor blending when varieties share the same root space.
