Where to grow peppers in your garden

The main thing to know about peppers is that they like a lot of heat and sunlight, so always grow them in the sunniest and most sheltered spot in your garden. A sunny window sill is also a good candidate for growing peppers – in fact, smaller varieties such as chilli peppers will easily grow on a sunny window sill indoors. 

The thicker and juicier your peppers, the more sun and warmth they will need to grow properly. If your garden/window sill isn't south facing, choose a thinner variety that needs less sun and less growing time to reach maturity. Try banana peppers, for example. 

How to grow peppers


1. Begin by planting seeds in a seed container or growing bag between February and late April. Remember, peppers like it warm and moist, so keep them in a greenhouse or indoors until the weather's warm enough for them to be planted outside.

2. When the seedlings are about three inches tall and have begun to form leaves, transplant them into pots or a garden bed. Pay attention to soil quality: if yours is poor, replace the top layer of your garden soil with nutrient-rich compost. If growing in containers, they'll be fine outside from mid-May onwards; plant out into open beds in late May.

3. Once your peppers plants are established, pinch out the side shoots if you don't want your peppers to be too big. Water regularly and harvest the fruit when it's full sized, green, and shiny. You can also leave them to ripen before picking, but that will give you a smaller harvest. 

Top tip: Peppers are prone to pests such as aphids; control them with a natural pesticide such as a castille soap and water solution.
