Home-grown cucumbers are delicious, so it's well worth raising your own crop from seed. Cucumber seed needs warmth to germinate, and should be sown indoors during April or May.

It's worth checking the seed packets before you buy and looking for varieties that produce all-female flowers, such as ‘Bella’ F1, ‘Baribal’ F1 or ‘Saturn’ F1. These varieties will form fruits without you having to pollinate the flowers by hand.

You will need

Good quality compost

Small pots

Watering can

Plant labels


Prepare 5cm pots by filling them to the top with seed-sowing compost. Gently push one or two seeds 2cm deep into the compost in each pot. Sprinkle more compost into the pot and tap the pot gently to level the surface.

Place a label in each pot if you are growing different varieties. If you are just growing one type, keep the pots in one labelled tray.

Soak each pot well and let the water drain through. Then move the seedlings to a warm, sunny windowsill to maintain a temperature of at least 18°C. You should see the seeds germinating in 7-10 days.
