Kale is a fantastic crop to grow in containers, especially if you're limited on space or simply want to add some greenery to your patio.
Quick Answer
To grow kale in containers, choose large pots or grow bags, use a quality compost mix, sow seeds from March to June, and ensure regular watering and feeding.
Getting Started with Container Kale
Growing kale in containers requires a bit of planning, but it's quite straightforward. Here's what you need to know:
Choosing the Right Container
The first step is selecting the right container. You'll want a pot or grow bag that's at least 30 cm in diameter and depth to allow ample room for root growth. Ensure your container has good drainage holes to prevent waterlogging, which kale dislikes.
Soil and Compost
Use a high-quality multi-purpose compost, ideally enriched with some slow-release fertiliser. Kale enjoys rich, well-draining soil, and adding some perlite or grit can improve drainage.
Planting Kale
Once you've got your container and soil ready, it's time to plant. You can start growing kale from seeds or young plants.
When to Plant
In the UK, the best time to sow kale seeds is from March to June. Start indoors if the weather is still frosty. If you’re using young plants, you can transplant them outdoors from April onwards.
| Month | Action | Notes |
|---|---|---|
| March | Sow indoors | Protect from frost |
| April | Transplant outdoors | Ensure frost-free |
| June | Final sowing | Harvest in autumn |
Planting Techniques
Sow seeds about 1 cm deep and space them about 15 cm apart if direct sowing. When transplanting seedlings, make sure to harden them off for a week before planting out to reduce shock.
Caring for Your Kale
Once your kale is planted, you'll need to care for it to ensure a healthy crop.
Watering and Feeding
Kale prefers consistent moisture, so water regularly, especially during dry spells. A liquid feed every few weeks will support leaf growth, particularly if using containers.
Pest Control
Watch for pests like aphids and caterpillars. Hand-pick or use a gentle spray of water to dislodge them. Consider using netting to protect young plants from pigeons, which are common in the Midlands.

Frequently Asked Questions
Can kale grow in winter?
Yes, kale is frost-tolerant and can continue growing slowly through winter if the weather is mild, especially in sheltered areas.
How often should I water container kale?
Water when the top inch of soil feels dry. In hot weather, this could be daily, but usually 2-3 times a week is sufficient.
What varieties of kale are best for containers?
Curly kale and dwarf varieties like 'Dwarf Green Curled' are particularly suited for container growing due to their compact size.
