Chard (Swiss chard or leaf beet) is an easy-to-grow, productive vegetable perfect for UK gardens. With colourful stems and nutritious leaves, chard is both ornamental and delicious. Hardy and tolerant of most conditions, it provides harvests almost year-round with minimal care. It's one of the crops I recommend most to anyone who's given up on spinach — I grow Bright Lights every year and it never seems to mind whatever the British summer throws at it. This comprehensive guide will show you how to grow chard successfully.

I've been growing vegetables on my Yorkshire allotment and raised beds since 2012. Everything I write is based on what I've actually grown, failed at, and eventually got right in a real UK climate.
Quick Growing Facts
- Sowing Time: March to August
- Harvest Time: 8-12 weeks after sowing, then continuously
- Growing Time: 8-12 weeks to first harvest
- Difficulty: Very easy
- Position: Full sun to partial shade
When to Sow Chard
Chard can be sown almost continuously for year-round harvests:
- Outdoor sowing: March-August for continuous harvests
- Spring sowing: March-May for summer and autumn harvest
- Summer sowing: June-August for autumn, winter, and spring harvest
- Succession sowing: Sow every 3-4 weeks for continuous supply
- Indoor sowing: Can start in modules in February-March for earlier crops
Soil Preparation
Chard is very adaptable and tolerates most soils:
- Soil type: Any reasonably fertile, well-drained soil
- Add organic matter: Dig in compost or well-rotted manure for best results
- pH level: Slightly acidic to neutral (pH 6.0-7.5)
- Tolerant: Tolerates poorer soils better than many vegetables
- Rake fine: Create a fine, level seedbed for direct sowing
How to Sow Chard
Direct Outdoor Sowing (recommended):
- Create drills: Make drills 2.5cm (1 inch) deep, 38cm (15 inches) apart
- Sow seeds: Sow seeds 10cm (4 inches) apart along the drill
- Cover and firm: Cover with soil and firm gently
- Water well: Water thoroughly after sowing
- Germination: Seeds germinate in 7-14 days
Indoor Sowing (for earlier crops):
- Sow in modules or small pots in February-March
- Sow 2-3 seeds per module, 2.5cm (1 inch) deep
- Thin to strongest seedling
- Plant out when 5-7.5cm (2-3 inches) tall
- Space 30-38cm (12-15 inches) apart
💡 Top Tip
Each chard ‘seed’ is actually a cluster of 2-4 seeds, so multiple seedlings will emerge from each sowing position. Thin to the strongest seedling to allow proper development, or leave small clusters for baby leaf harvests.
Thinning Seedlings
Proper thinning ensures good-sized plants:
- Thin when seedlings are 5-7.5cm (2-3 inches) tall
- Final spacing: 30-38cm (12-15 inches) apart
- Water before thinning to make the task easier
- Thinnings can be used as baby salad leaves
Ongoing Care
Chard is very low-maintenance:
- Watering: Water regularly during dry spells to prevent bolting and keep leaves tender
- Feeding: Generally no feeding needed; can apply liquid fertiliser if growth is slow
- Mulching: Apply mulch to retain moisture and suppress weeds
- Weeding: Keep weed-free, especially when young
- Remove flower stalks: Cut off any flower stalks that appear to prolong leaf production
- Winter protection: Cover with cloches or fleece in severe weather for continued harvests
Common Problems
Bolting: Running to seed prematurely. Caused by drought or cold shock. The RHS notes chard is more heat- and bolt-resistant than spinach, so it copes better with UK summers. Water regularly and use bolt-resistant varieties for early sowings.
Leaf miner: Larvae tunnel in leaves causing brown blisters. Remove affected leaves; doesn't usually affect plant health.
Slugs and snails: Can damage young plants. Protect with barriers or organic pellets.
Birds: May peck at leaves in winter. Protect with netting if necessary.
Harvesting Chard
Chard provides continuous harvests with cut-and-come-again picking:
- Timing: First harvest 8-12 weeks after sowing
- Pick outer leaves: Harvest outer leaves first, leaving inner leaves to grow
- Cut, don't pull: Use a sharp knife to cut leaves 2.5cm (1 inch) above ground level
- Regular picking: Harvest regularly to encourage more production
- Leave some leaves: Always leave at least 4-5 leaves on the plant
- Baby leaves: Can harvest as baby leaves when 7.5-10cm (3-4 inches) tall
- Continuous harvest: Plants can produce for 6-12 months with regular picking
- Winter harvest: Hardy varieties continue producing through mild winters
Storage
Chard is best eaten fresh but can be stored briefly:
- Fresh: Store in the refrigerator for up to 5 days
- In water: Stand stems in water like cut flowers to keep fresh
- Freezing: Wash, chop, blanch for 2 minutes, cool, then freeze for up to 12 months
- Cooking: Use leaves like spinach; stems can be cooked separately like asparagus
Recommended Varieties
Colourful Varieties (ornamental and edible)
Bright Lights
A rainbow mix of red, yellow, orange, pink and white stems — the variety I grow myself for sheer reliability and looks.
Rainbow Chard
A similar colourful mix to Bright Lights — a good alternative seed source for the same vibrant effect.
Rhubarb Chard
Deep red stems and veins with good flavour — striking in a bed and excellent for adding colour to dishes.
Bright Yellow
Bright yellow stems with a mild flavour — good if you want a single strong colour rather than a mix.
Traditional Varieties
Fordhook Giant
White stems, large leaves, and very productive — the reliable choice if you want maximum yield.
Lucullus
Pale green, crinkled leaves with excellent flavour — a good traditional choice for the kitchen.
Perpetual Spinach
Narrow green stems with a spinach-like flavour and excellent hardiness — the best substitute if spinach keeps bolting on you.
Essential Tools for Growing Chard

Chard and beetroot are the same species — chard was simply bred over centuries for its leaves and stems rather than its root, which is why a chard plant left to its own devices will eventually try to form a small, woody beet.
Frequently Asked Questions
Why does my chard keep bolting?
Bolting is usually triggered by drought or a cold shock early in growth. Chard is more bolt-resistant than spinach, so this is less common, but consistent watering and avoiding very early sowings helps prevent it.
Will chard survive winter outdoors?
Yes, in most UK gardens — chard is hardy and will keep producing through a mild winter, especially under a cloche or fleece. In exposed or very cold spots, growth slows considerably but the plant usually survives.
How long does a chard plant keep producing?
With regular cut-and-come-again picking, a single sowing can keep producing leaves for 6-12 months. Plants eventually bolt or become woody, at which point it's worth sowing a fresh batch.
Can I grow chard in a container?
Yes — chard does well in a container at least 25cm deep, and its tolerance of poorer soil makes it more forgiving than many vegetables if your compost isn't perfect.
Is rainbow chard as productive as plain green varieties?
Yes — varieties like Bright Lights and Rhubarb Chard are just as productive as traditional green types such as Fordhook Giant, with the bonus of colourful stems.
