What to sow in Newcastle

Newcastle's coastal proximity moderates temperatures, but cold North Sea winds ('the haar') can set growth back in spring. Choose sheltered spots and start tender crops indoors — once summer arrives, the long daylight hours help crops catch up.

What to sow in Newcastle right now

Based on a last frost date of 9 May, these are the crops you can get going in Newcastle this month.

Swiss chardBeautiful and productive. Pick outer leaves and it keeps going for months. Rainbow chard looks stunning.
Plant out
LeeksDrop seedlings into deep holes and just water in — no need to fill the hole. They'll fatten up on their own.
Plant out
SweetcornPlant 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.
Direct sowPlant out
CourgettesYou only need 2-3 plants. Seriously. Pick them small (15cm) or they turn into marrows overnight.
Direct sowPlant out
French beansDwarf varieties need no support. Pick every few days — once they start producing, they don't stop (unless you let pods go to seed).
Direct sowPlant out
SquashBig hungry plants — give them space and feed them well. Leave to cure in the sun before storing and they'll keep for months.
Plant out
PumpkinsLimit each plant to 2-3 fruits for bigger pumpkins. Sit them on a tile or slate to stop rot from underneath.
Plant out
Pak choiSow early spring or after midsummer — it'll bolt faster than you can blink in the heat. Worth it though. Fast-growing and very rewarding.
Direct sow
FennelSow after midsummer for best bulbs — earlier sowings often bolt. Don't transplant bare-root, it hates root disturbance. Use modules.
Direct sowPlant out
CelerySow 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.
Plant out
DillSow direct — dill absolutely hates being transplanted. Short rows every few weeks for continuous supply. Gets to 90cm, so give it a sheltered spot.
Direct sow
TomatoesPinch 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.
Plant out
PeppersStart early — they're slow growers. Pinch out the first flower to encourage bushier growth and more fruit overall.
Plant out
ChilliesNeed heat to germinate — use a propagator or the warmest windowsill you've got. The more sun they get, the hotter the fruit.
Plant out
CucumbersOutdoor varieties are tougher and easier than greenhouse ones. Keep picking and they keep producing — ignore them and they swell to marrow size.
Plant out
Runner beansBuild a strong frame — they get seriously heavy. Pick every 2-3 days or they go stringy and the plant stops producing.
Direct sowPlant out
AubergineStart very early — January isn't too soon. Limit to 5-6 fruits per plant if you want decent-sized aubergines rather than marbles.
Plant out
BasilPinch 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.
