What to sow inMay

Plant in a block, not a row — they're wind-pollinated and need neighbours. Each plant gives you 1-2 cobs, so don't be stingy with numbers.

You only need 2-3 plants. Seriously. Pick them small (15cm) or they turn into marrows overnight.

Dwarf varieties need no support. Pick every few days — once they start producing, they don't stop (unless you let pods go to seed).

Bolts at the slightest excuse. Sow every 3-4 weeks, pick frequently, and choose slow-bolt varieties. It's a race you can win if you stay on top of it.

Sow early spring or after midsummer — it'll bolt faster than you can blink in the heat. Worth it though. Fast-growing and very rewarding.

Sow after midsummer for best bulbs — earlier sowings often bolt. Don't transplant bare-root, it hates root disturbance. Use modules.

Sow direct — dill absolutely hates being transplanted. Short rows every few weeks for continuous supply. Gets to 90cm, so give it a sheltered spot.

Build a strong frame — they get seriously heavy. Pick every 2-3 days or they go stringy and the plant stops producing.

Pinch out flower buds to keep leaves coming. Harvest from the top to encourage bushy growth. Loves heat — don't even think about putting it outside before June.

Each seed cluster produces several seedlings — thin to the strongest. Don't chuck the leaves, they're delicious wilted with butter.

Beautiful and productive. Pick outer leaves and it keeps going for months. Rainbow chard looks stunning.

Drop seedlings into deep holes and just water in — no need to fill the hole. They'll fatten up on their own.

Cut the main head first and you'll get side shoots for weeks. Purple sprouting is the real star — worth the long wait.

Big hungry plants — give them space and feed them well. Leave to cure in the sun before storing and they'll keep for months.

Limit each plant to 2-3 fruits for bigger pumpkins. Sit them on a tile or slate to stop rot from underneath.

Sow seeds on the surface — they need light to germinate. Start early in a propagator. Cutting celery is much easier than trench celery if you're new to it.

Pinch out side shoots on cordon types. Feed weekly with tomato feed once the first truss sets. Don't overwater — flavour comes from a bit of stress.

Start early — they're slow growers. Pinch out the first flower to encourage bushier growth and more fruit overall.

Need heat to germinate — use a propagator or the warmest windowsill you've got. The more sun they get, the hotter the fruit.

Outdoor varieties are tougher and easier than greenhouse ones. Keep picking and they keep producing — ignore them and they swell to marrow size.

Build a strong frame — they get seriously heavy. Pick every 2-3 days or they go stringy and the plant stops producing.

Start very early — January isn't too soon. Limit to 5-6 fruits per plant if you want decent-sized aubergines rather than marbles.
