How to Grow Spinach and Chard in the UK

Spinach and chard are two of the most rewarding leafy greens you can grow in a UK garden — fast, generous, and forgiving once you understand their habits. True spinach gives you tender, melt-in-the-pan leaves in a matter of weeks; chard keeps cropping for months on end, often shrugging off frost and looking gorgeous while it does it. This guide covers both, with honest UK timings and a plan to dodge their one big foible: bolting.

If you only ever grow one pair of leafy greens, make it these. They suit beds, raised beds and large pots, they're happy in a bit of shade, and you pick from the same plants over and over rather than harvesting once and starting again.

Why grow spinach and chard

Leafy greens are the crop that quietly earns its keep all year. A short row keeps a kitchen in fresh greens for weeks, and because both spinach and chard are cut-and-come-again crops, you pick the outer leaves and the plant simply grows more. There's no "harvest day" — just a steady supply you graze from whenever you cook.

They're nutritious in the way that actually matters to a beginner: you grow them, you eat them, and home-grown spinach picked an hour before dinner is a completely different vegetable to the bagged supermarket version.

Both are genuine cool-season crops, which is good news for the UK. They germinate and grow well in the mild, damp conditions that define most of our growing year — spring and autumn especially. That's also why they're among the easiest crops for beginners: you're working with the British climate rather than against it, unlike heat-lovers such as tomatoes or peppers that need coddling.

The one catch is that true spinach hates heat. Give it warm, dry, long summer days and it sprints to flower instead of making leaves. Once you know that, you simply garden around it, and chard is there to fill the summer gap that spinach leaves behind.

True spinach vs chard vs perpetual spinach

These three crops get muddled constantly, partly because two of them have "spinach" in the name and only one of them is actually spinach. Sorting them out is the single most useful thing in this guide.

True spinach (Spinacia oleracea) is the real thing: soft, rounded or pointed leaves, mild and tender, ready in six to ten weeks. It's the quickest of the three and the best raw in salads. It's also the diva — it bolts (runs to seed) the moment summer gets warm or the days get long, so it's a spring and autumn crop, not a midsummer one.

Swiss chard (Beta vulgaris) isn't spinach at all — it's a leaf beet, closely related to beetroot, grown for its leaves rather than its root. The leaves cook down much like spinach but the plant is far tougher: slower to bolt, far more heat-tolerant, and the broad central stems (white, or bright pink, yellow and red in the rainbow types) are a vegetable in their own right. One sowing crops for many months.

Perpetual spinach (also called leaf beet or spinach beet) is another leaf beet — essentially a plainer-stemmed cousin of chard. It tastes closer to true spinach than chard does, but inherits the leaf beet toughness: it laughs off the heat that finishes true spinach, and a spring sowing will often crop right through to the next spring. It's the best all-rounder of the three for a beginner who wants spinach-style leaves with the least fuss.

For a deeper look at the leaf beets — including how to grow them, harvest the stems, and keep them going through a UK winter — see our dedicated guide to perpetual spinach and chard. The short version: grow a little true spinach for tender spring and autumn leaves, and lean on chard or perpetual spinach to cover the summer and the colder months.

Choosing varieties

You don't need a long list. A couple of reliable varieties of each will keep you in greens all year.

True spinach

• 'Medania' — a dependable, slow-to-bolt variety that's earned its place as a UK favourite. Good for both spring and autumn sowings, and more forgiving of warm spells than older sorts. A sensible first choice.
• 'Perpetual' — confusingly named (it's a leaf beet, i.e. perpetual spinach, not true spinach), but worth knowing as a packet name. If you want genuine staying power and spinach-ish leaves, this is the one to reach for.
• 'Apollo' or other bolt-resistant F1 types — modern F1 hybrid spinach is bred to resist bolting and stay productive longer. Worth the slightly higher seed price if you've struggled with plants running to seed.

Chard

• 'Bright Lights' — the famous rainbow chard, with stems in pink, gold, orange, crimson and white. As ornamental as it is edible — it earns a spot in a flower border, not just the veg patch.
• 'Fordhook Giant' — the classic heavy-cropping white-stemmed chard. Big, glossy, productive leaves and broad stems; the workhorse choice if you mainly want eating volume rather than colour.
• 'Rhubarb' / 'Ruby' chard — deep red stems and veins, slightly stronger flavoured, and very handsome.

If you're brand new to growing and want the lowest-effort option, start with 'Fordhook Giant' chard or any perpetual spinach: both germinate readily, ignore the weather, and crop for ages. Add a packet of 'Medania' true spinach for those tender spring and autumn pickings.

Where to grow

Both crops are easy-going, but a little thought about position makes a real difference to how long they last before bolting.

Light. Give them an open spot in spring and autumn — they'll appreciate the light when it's in short supply. In summer, though, the opposite is true: a bit of dappled or afternoon shade actually helps, because it keeps the soil cooler and slows bolting in true spinach. They're among the few crops genuinely happy in part shade, which makes them brilliant for a bed that doesn't bake all day. If you have a tricky shadier corner, this is the crop for it.

Soil. Aim for rich, moisture-retentive ground. These are leafy crops, so they want nitrogen and they want to stay damp — dry roots are the fastest route to a bolted plant. Dig in or mulch with plenty of garden compost before sowing; if your soil is thin or sandy, working in organic matter to hold water is the best thing you can do. Our guide to improving your soil covers this, and if you make your own, see how to make compost. A surface mulch of compost on a no-dig bed does the same job and keeps moisture in beautifully.

Containers. Both grow well in pots and troughs — useful if you're short on ground. Use a container at least 20cm deep, fill with a good multipurpose compost, and be ready to water often, as pots dry out fast and dry roots trigger bolting. See growing food in containers for the basics.

Sowing

Sowing is simple. The skill is all in the timing — getting your seed in during the cool windows and steering true spinach clear of midsummer.

True spinach — spring sowing (March–May). Sow direct into prepared soil from March once the ground is workable. Make a shallow drill about 2.5cm deep, sow seeds thinly, cover and water. Seeds need cool, moist soil to germinate well — warm soil actually suppresses germination, which is another reason midsummer sowings struggle. Thin seedlings to about 15cm apart for full-size plants (use the thinnings as baby leaves).

True spinach — autumn sowing (August–September). This is the sowing many gardeners rate most highly. Sown in late summer as the heat fades, plants establish in the cooling weather, give you autumn pickings, and — with a cloche or cold frame — stand through winter to crop again in early spring. Far less prone to bolting than late-spring sowings.

The midsummer warning. Don't sow true spinach in June or July expecting leaves. Long days plus warmth means it germinates (if at all) and bolts almost immediately. If you must have summer spinach, sow a bolt-resistant variety in the coolest, shadiest spot you have and keep it soaked — or, far better, grow chard or perpetual spinach instead and let them carry the summer.

Chard and perpetual spinach (April–July). Sow direct from April through to July. The seed is actually a cluster, so a few seedlings often come up together — thin them to one strong plant every 25–30cm. They size up bigger than true spinach and crop for far longer, so you need fewer plants.

To keep true spinach coming steadily rather than all at once, use successional sowing: sow a short row every two to three weeks through the spring and autumn windows rather than one big batch. A row or two of each at a time is plenty for most households. The planting calendar helps you map the gaps so you're never without greens or drowning in them.

Care

Once it's up, this crop asks for very little — but the one job that matters, it really matters.

Watering is everything. The single biggest cause of disappointment with spinach is dry roots, which trigger bolting — the plant abandons leaf-making and shoots up a flower stalk, after which the leaves turn bitter and tough. Keep the soil consistently moist, especially in dry or warm spells and especially for true spinach. A good soak two or three times a week in summer beats a daily splash. Mulching around the plants helps hold that moisture in.

If your plants do run to seed despite your best efforts, don't take it personally — true spinach is genuinely quick to bolt, and a hot dry week can do it. Our guide to why spinach bolts and how to stop it walks through the triggers (heat, long days, dry roots, crowding) and the practical fixes, from choosing bolt-resistant varieties to providing summer shade.

Feeding. On reasonably rich soil you won't need to feed much. For long-season chard and perpetual spinach, a liquid feed every few weeks, or a top-up of compost mulch mid-season, keeps the leaves coming. Leafy greens respond well to nitrogen — too little and growth stalls and pales.

Weeding and spacing. Keep young plants weed-free so they aren't competing for water and light. Don't crowd them: plants packed too tightly stress more easily and bolt sooner, so respect the spacing when you thin.

Winter protection. Chard and perpetual spinach are tough enough to stand most UK winters outdoors, though they slow right down and may look battered after hard frost — they usually bounce back in spring. Autumn-sown true spinach is hardier than the spring crop and well worth covering (see below).

Harvesting cut-and-come-again

This is where these crops shine, and where beginners often under-harvest. You don't wait and pull the whole plant — you pick the outer leaves regularly and leave the central growing point to keep producing.

True spinach. Start picking once leaves are big enough to bother with — baby leaves at five or six weeks for salads, larger leaves a little later for cooking. Take the outer leaves first, working round the plant, and never strip it bare: leave at least a third of the leaves so it can recover. Picked this way, a spring sowing keeps going for several weeks before it eventually bolts.

Chard and perpetual spinach. Same approach, but for far longer. Snap or cut the outer stems off at the base when the plant is established (from about ten weeks), and it'll throw up new leaves from the centre continuously. Keep harvesting and you keep the plant young and productive; let it sit unpicked and it slows down. One healthy chard plant can crop, on and off, for the best part of a year.

Pick in the cool of the morning when leaves are turgid, and use them quickly — spinach especially wilts fast once cut. Young leaves go raw into salads alongside lettuce; larger leaves wilt down in seconds in a hot pan. Chard stems take a few minutes longer to cook than the leaves, so it's worth separating them and giving the stems a head start.

Winter cropping under cover

One of the quiet joys of these crops is fresh greens in the hungry gap of late winter, when little else is going.

Autumn-sown true spinach is the key. Sown in August or September and given protection as the cold sets in, it sits quietly through the worst of the winter and then crops generously from late winter into early spring — exactly when you most want something green and home-grown. A cloche, cold frame, or low polythene tunnel makes the difference between leaves you can pick and a sad, frost-flattened row.

Under glass, the season stretches further still. A greenhouse or polytunnel bed sown with spinach or chard in early autumn will keep you in leaves through much of the winter, and the plants romp away again the moment light levels lift in February. If you grow greenhouse crops, these are a brilliant winter use for the space once the greenhouse tomatoes have finished for the year.

Chard and perpetual spinach generally need no cover at all to survive a UK winter outdoors, but a cloche keeps the leaves cleaner and pickable in the worst weather. For more on keeping the leaf beets going through the cold months, see our guide to perpetual spinach and chard.

Once you've got the hang of a few quick crops like this, it's worth a look at how to start a vegetable garden to plan the rest of your beds around them.

Problems

Spinach and chard are largely trouble-free, but three issues come up often enough to know about.

Bolting (running to seed). By far the most common problem, and it's almost always true spinach rather than chard. The trigger is heat, long midsummer days, dry roots, or crowding — the plant gives up on leaves and shoots up a flower spike, and the leaves turn bitter. The fixes: sow in the cool spring and autumn windows, never midsummer; keep the soil consistently moist; choose bolt-resistant varieties; give summer crops some shade; and don't sow too thickly. Once a plant has bolted there's no rescuing it — pull it and sow again in better conditions. The full rundown is in why spinach bolts.

Downy mildew. A common spinach disease in cool, damp UK conditions, showing as yellow patches on the upper leaf surface with a greyish, fuzzy mould underneath. It spreads in crowded, humid, wet foliage. Reduce it by sowing thinly with good air flow, watering the soil rather than the leaves, clearing away affected leaves, and rotating where you grow it year to year — see crop rotation. Mildew-resistant varieties are widely available if it's a recurring problem.

Leaf miner. The grubs of the beet leaf miner tunnel inside chard, perpetual spinach and beetroot leaves, leaving pale, papery blotches (the larvae mine between the upper and lower leaf surfaces). It's more cosmetic than fatal: pick off and bin affected leaves as soon as you see the blotches, and the plant grows on fine. A fine insect-proof mesh over the crop stops the adult flies laying in the first place. Note it affects the leaf beets and beetroot, not true spinach.

You'll rarely meet slugs as a serious problem with established plants, though seedlings are worth protecting like any other.

The same cut-and-come-again approach works for lettuce and other salad leaves — between them and a row or two of chard, you can keep a kitchen in greens nearly all year.

Whether you start with a single packet of chard or sow a little of everything, spinach and the leaf beets reward you out of all proportion to the effort. Keep the roots moist, sow in the cool windows, pick the outer leaves little and often — and you'll have home-grown greens on the plate for most of the year.
