Chilli Plant’s Compost Buyer’s Guide

The right chilli seed compost can make a huge difference to the health of your chillies. Chillies like good draining soil, with a pH of between 6 and 7. The best fertiliser you can find is pointless if the soil doesn’t hold the good nutrients, so ensure that the water doesn’t flow through the soil too quickly.

Chillies have very shallow roots, so the best compost needs to be loose to allow the roots to spread out. There are many things you can add to your soil to improve the texture, but the right chilli compost should be loose enough in the first place.

Many eco-conscious gardeners opt for a peat free or reduced peat compost. These composts contain a mix of organic materials mixed with inorganic material. 100% peat free is best for the environment, but even those with low levels of peat can significantly reduce your footprint. Check the label and remember that if it doesn’t say ‘100% peat free’, it most likely contains peat.

The best time to plant your chilli seeds is the beginning of March, but you can plant them as early as February and as late as April. When planting your chillies, ensure they are planted in warm compost, and keep the soil moist at all times. Chilli plants love warmth and light, but they can be damaged by the sun. They should have some sunlight, but not so much that they get scorched.

Conclusion

Perfectly grown chillies require the right compost, and it’s the New Horizon Vegetables Growing Compost that tops our list as the best compost for chilli seeds. It’s sustainable, peat-free and great quality – perfect for the eco-conscious chilli grower!
