Are you unsure which chilli pepper to grow? @london.organic.home.garden recommends chilli ‘Basket of Fire’: “It produces up to 200 chillies per plant and they mature in a rainbow of colours from dark purple, through to yellow, orange and finally red.” See their prolific outdoor-grown plant for yourself in their Insta post. Be warned though – this attractive variety packs a punch in Scoville units!
Hema – Grow With Hema
Hema, creator of blog Grow With Hema, recommends a warm and dark boiler cupboard for germinating your chilli seeds. “Within a couple of weeks, the chilli seeds will germinate with little green blobs peeping through,” she says. At that stage, they’re ready to move into a brighter part of the house.
Janie – @janie.boots
If you want to make a super early sowing of chilli seeds, use a heat mat like @janie.boots to provide a constant, warm temperature. Her preferred variety of chilli seeds need to be kept at 27℃ to germinate successfully, and she always sows them in December to give her chillies the longest growing season possible. “The head start really paid off last season and I’m still getting fresh chillies indoors from this plant I brought in to overwinter,” she says. See her fun seed set-up for yourself in her post!
Geoff Wakeling – Brimwood Farm
Geoff’s tip for growing sweet bell peppers outdoors? Start them as early as January in a heated propagator.

John Harrison – Allotment & Gardens
Deter red spider mites from your developing sweet pepper plants by misting them with water, says John Harrison of Allotment & Gardens. Misting your plants when they’re in flower is also a great way to encourage your flowers to set fruit, he says.

Ben Vanheems – GrowVeg
“Move [greenhouse] plants outside if temperatures soar,” advises Ben Vanheems on the GrowVeg YouTube channel. If your greenhouse gets too hot, then flowers will simply abort and drop off the plant, he explains. Combat unwanted flower drop in hot weather by dousing the floor with water, or by standing pots over trays of water to raise the humidity, he says. Ben’s video gives a full overview of chilli growing, including some excellent tips on how to pot on your plants.

Laura from Homegrown and Hopeful found that changing her growing environment had amazing effects on her chilli and sweet pepper yield.

The Oxfordshire Chilli Garden
Have you noticed little white marks on the outer skin of your ripening jalapeños? Don’t worry, this is just a result of the inside of the chilli growing faster than the outside.

And it’s not just jalapeños; it can happen to any plump and thick-skinned chilli! Learn more about corking and see how these experts turn their jalapeños into a rich and smoky Chipotle.

Chillies are really easy to dry and preserve for use through the winter months, says Thompson & Morgan’s in-house expert Sue Sanderson. “Take a needle, and thread the stems of the chilli peppers together on some twine so that they form a daisy chain,” she says.
