My chilli plants always produce loads of tasty fruits when I use this type of compost – and experts say it's key to successful crops

Chillies are one of my all-time favourite crops to grow. I had brilliant luck growing my first ever chilli pepper plant indoors, and it was so rewarding to watch the fruits form. Choosing the best soil for chillies, though, can mean an even better yield.

Gardeners more commonly grow chillies in pots, which gives them total control over the soil they use. Chilli peppers adore free-draining soil – but other potting mix features can lead to a more fruitful harvest, too.
