The Easiest Crops for Kids to Grow

The secret to growing with children is speed. A small child measures time very differently to a grown-up, and a seed that takes three months to do anything will be long forgotten before the first leaf appears. So the trick is to pick crops that are fast, fun and almost impossible to get wrong — the sort of thing that rewards a bit of attention within days or weeks rather than seasons.

This guide rounds up the best crops for keeping young gardeners interested, each with a little angle to make it exciting and one practical tip to help it succeed. It's part of our wider getting kids growing section, so once you've picked a winner here you'll find plenty more projects to try together.

Fast wins — ready in days or weeks

These are the crops to reach for first. They sprout quickly, ask very little, and almost never fail — exactly what an impatient five-year-old needs.

Cress (about a week)

Cress is the undisputed champion of child-friendly growing. Scatter the seeds on damp kitchen roll or cotton wool, pop it on a windowsill, and you'll see green shoots within two or three days. By the end of the week there's a little forest to snip and eat in an egg sandwich.

The real magic is that cress needs no compost, no garden and barely any patience. Children can grow it in an eggshell with a face drawn on, in a yoghurt pot, or spelling out their initials on the tray. Our full guide to growing cress has all the fun variations.

Tip: keep the kitchen roll damp but not swimming, and give it a bright spot out of direct scorching sun. Snip with child-safe scissors and supervise the cutting.

Radishes (3–4 weeks)

If you want a real vegetable on the plate fast, radishes are the answer. Sown straight into a pot or a patch of soil from March to September, they're ready to pull in as little as three to four weeks. Children love yanking them out of the ground to reveal that bright pink surprise underneath.

Tip: sow thinly so the roots have room to swell — if they come up in a thick clump, thin them out so each plant sits a couple of centimetres apart. Sow a short row every couple of weeks for a steady supply rather than a glut all at once.

Salad leaves (cut-and-come-again)

Loose-leaf lettuce and mixed salad leaves are brilliant because they keep on giving. Instead of waiting for a whole heart to form, you snip the outer leaves and the plant grows more — sometimes for weeks. That "cut-and-come-again" trick feels like a small miracle to a child, and it puts a homegrown salad on the table again and again from one sowing.

A windowbox, a trough or an old colander all work well. For the full method — varieties, timing and how often to pick — see our guide to growing lettuce.

Tip: sow a pinch of seed every two to three weeks from spring through to early autumn so you never run out, and keep the compost just moist to stop the leaves turning bitter.

Big and exciting — crops with wow factor

Once the quick wins have done their job, these slightly slower crops bring real drama: height, hidden treasure and proper harvests worth waiting for.

Sunflowers (the height contest)

Nothing captures a child's imagination quite like a sunflower racing skyward over the summer. Sown in a pot indoors in April or straight outside in May, the giant varieties can soar to two metres or more — often taller than the grown-ups by August.

Turn it into a competition: let each child grow their own, mark their heights on a stick or a wall, and see whose wins. It's a lovely excuse to get outside and measure together. Our growing sunflowers guide covers the best tall varieties and how to keep them standing.

Tip: push a cane in early and tie the stem loosely as it grows — a tall sunflower can topple in a summer downpour or a gusty spell. Leave the seedheads up in autumn and the birds will thank you.

Potatoes in a bucket (a treasure-hunt harvest)

Growing potatoes in an old bucket or a sturdy compost bag turns harvest day into a proper treasure hunt. You tip the whole thing out onto a tarpaulin and dig through the compost with bare hands, finding potato after potato hidden in the soil. The look on a child's face when they unearth a dozen spuds from one seed potato is hard to beat.

Plant one or two seed potatoes (the special ones sold for planting) into a large bucket with drainage holes in spring, top up with compost as the shoots grow, and tip it out around midsummer for first earlies.

Tip: only ever plant proper seed potatoes from a garden centre, not old supermarket spuds — and remind children that potato leaves, flowers and any green tubers are not for eating.

Runner beans (fast and tall)

Runner beans grow at a pace children can actually watch. Sow the big, easy-to-handle beans in May or June, give them a wigwam of canes, and within weeks they're twining upwards and covered in cheerful red flowers, followed by long pods to pick all summer. The seeds are large enough for small fingers to plant one by one, which makes them a satisfying job.

They're one of the most rewarding crops to grow with a family — and if you've got the space, you can train them over a frame to make a living den. See our full runner and climbing beans guide for the details.

Tip: keep picking the pods while they're young and tender; the more you pick, the more the plant produces. Beans must be cooked before eating — raw runner beans aren't good for tummies.

Pumpkins (for Halloween)

Few projects feel as worthwhile as growing your own Halloween pumpkin. Sow seeds indoors in April or May, plant the young plants out in early June once the frosts have passed, and let them sprawl across a sunny corner all summer. By late October there's a homegrown pumpkin ready to carve — grown from a seed the child planted themselves back in spring.

Tip: pumpkins are hungry, thirsty and need plenty of room, so give each plant a square metre or two and a spot in full sun. Slip a tile or piece of wood under each fruit to keep it off damp soil and stop it rotting.

Sweet treats — crops kids will actually eat

The crops children grow are the crops children eat. These three turn the garden into a pick-your-own snack bar.

Cherry tomatoes (sweet snacks)

Cherry tomatoes are little bursts of sweetness that children happily graze straight off the plant. A single plant in a large pot or grow bag on a sunny patio can produce handfuls of fruit all summer, ripening from green to glowing red. Tumbling varieties even trail down from a hanging basket, perfectly placed for small hands.

Our growing tomatoes guide explains how to feed and water them for the sweetest crop — and warm, sheltered UK summers suit them better than you might expect.

Tip: water consistently and feed once the first flowers appear. Let children do the daily "is it ripe yet?" check — picking and eating a sun-warm tomato is half the fun.

Strawberries

A homegrown strawberry tastes like nothing from a supermarket punnet, and that's exactly why children love growing them. Plant a few in pots, a hanging basket or a strawberry planter, and from early summer there's a steady trickle of red berries to hunt for among the leaves. Each plant sends out runners too, so children can watch new baby plants form on long stems — free strawberries for next year.

See our growing strawberries guide for the best varieties and how to keep the slugs off.

Tip: tuck a little straw or a mat under the fruit to keep it clean and dry, and net the plants if birds beat you to the harvest.

Peas (eaten raw off the plant)

Garden peas are one of the few vegetables children will happily eat raw, straight from the pod, still warm from the sun. Popping open a pod to find the sweet green peas inside is a small thrill that never gets old, and the sweetness fades so fast after picking that you really can only get it from your own plants.

Sow them in spring with the support of some twiggy sticks or netting to scramble up. Mangetout and sugar snap types are eaten pod and all, which is even less fiddly for little ones.

Tip: sow a few extra — a fair number get eaten on the spot and never make it as far as the kitchen.

Tips for success with children

A few simple habits make all the difference between a child who's hooked on growing and one who wanders off after a fortnight.

Give them their own pots. A patch or container that belongs entirely to the child — with their name on a lolly-stick label — turns growing from a chore into a point of pride. They'll water it more, check it more and care far more about what comes up.

Start with the quick crops. Lead with cress, radishes and salad leaves so the first experience is success, not a long wait. Save the slower sunflowers, pumpkins and strawberries for when they've already tasted the reward of growing something.

Keep expectations low on the tricky ones. Some things are wonderful to grow but rarely deliver a harvest in the UK — and that's fine, as long as everyone knows it going in. Be honest from the start that an avocado stone or apple pip makes a fun houseplant but almost never fruits here, and a carrot top regrows feathery leaves rather than a new carrot. Framed as an experiment, those make great projects; framed as a promise of dinner, they only disappoint.

If you'd like a deeper look at what grows easily in UK gardens — including the reasons behind the timings — our grown-up easiest crops for beginners guide pairs nicely with this list. And once the children have caught the bug, head back to the kids' growing hub for experiments, dens and more projects to try together.

Whatever you choose, the most important ingredient is enthusiasm. Pick something fast, get a bit of soil under their fingernails, and let the first green shoots do the rest — there's no better way to turn a curious child into a lifelong grower.
