Grow your own peppers
Peppers will do best if you've got a greenhouse, but if not you can still grow them in a sunny patch. Kids will love watching the peppers grow and change colour.

Did you know?

All peppers start out green and change colour as they mature.

What you'll need

  • Heated propagator (you can buy these for around £20)
  • Sweet pepper seeds
  • 7.5cm (3in) pots
  • Growbags or 22.5cm (9in) pots
  • Compost
  • Tomato feed
  • Trowel

When to start planting


When are they ready?

July to October.

Where to plant?

In a pot or grow bag in a sunny spot or in a greenhouse if you've got one.

Step-by-step guide

1. Sow your seeds into compost in a heated propagator, set to 21 degrees, in February or March. Leave on a sunny windowsill or in a greenhouse.
2. When the seedlings are big enough to handle, pot them into 7.5cm (3in) pots. Leave to grow in your greenhouse or in a sunny place.
3. When roots show at the bottom of the pot, they can be 'planted out'. Plant 3 into a growbag or put 1 plant per pot in a 22.5cm (9in) pot.
4. When they get to be about 20cm tall, give them support with a small cane and tie with garden twine.
5. Once the first peppers appear, feed them with tomato feed every fortnight to keep the compost moist (but not permanently wet).
6. Pick the first peppers when they're small, this will encourage more to follow.
7. If there's not enough sun to ripen the peppers, pick them and leave them to colour up in a warm place indoors.


You can buy a pack of seeds for less than £2.

Top tip for growing

When your pepper plants reach about 45cm tall, if they're not particularly bushy then pinch out the growing tips. This will encourage more fruit.
