Position
Chilli plants thrive in a warm, sunny environment, requiring a minimum of 6 hours of direct sunlight each day. Their tender nature makes them particularly sensitive to heat, so choosing a sheltered spot is crucial, especially in cooler climates.
Soil
For optimal growth, it’s essential to use well-draining soil that is rich in organic matter.
Chilli plant prefers a pH level between 6.0 and 6.8.
Rich nutrient-rich soil and adding half a bag of Volcanic Rock Dust (R25 per bag) and a bag of Superfrass (R25 per bag) will assist in rapid growth
Watering
Water regularly to keep the soil moist but not soggy. The plants prefer deep watering to encourage strong root development.
Too much water can lead to root rot, so make sure the soil is well-drained.
To grow in the ground, choose a spot with well-drained, fertile, moisture-retentive soil. If your soil is poor or very heavy, dig in a few bucketfuls of organic matter, such as garden compost or well-rotted manure, before planting.
Watering
Regular watering is a must for chilli plants, but it’s important to avoid overwatering, as these plants are sensitive to waterlogging. A good rule of thumb is to water when the top inch or two of soil feels dry to the touch.

(lose water from their leaf pores), which in turn affects how much water their roots absorb from the soil. If air humidity is low, plants transpire quickly and become at risk of wilting if water is lost from the leaves faster than it can be absorbed by the roots.
Mulching
Chillies need a steady supply of moisture to grow and crop well, so water as needed, aiming to keep the soil or potting compost evenly moist. Flower buds may fall off if plants get too dry.
If you’re growing your chilli plants in the ground, remember to mulch the soil with a thick layer of organic matter. This simple step will help you retain moisture and keep your plants healthy.
Fertilising
Feed chilli plants in containers with an organic, high potassium, liquid fertiliser weekly, as soon as flowering starts. Plants growing in enriched soil may not need regular feeding, but doing so can help to boost yield.
Pruning
Good ventilation and regular pruning can help prevent pest and disease issues.
Pinching out the growing tip of chilli plants is not usually needed to ensure a good crop, but can be done once plants reach around 30cm (1ft) tall to produce a bigger crop of smaller fruits. Be prepared that pinching out can delay fruiting.
When grown outdoors, fruiting may be reduced, especially in cooler summers.
Pests & Diseases
Several sap-sucking insects can cause problems, particularly when plants are grown indoors, so check them regularly. Aphids, grey mould, and red spider as well as fruit flies may sting ripening fruit. Use our EM Control
Harvesting:
Harvest chillies when they are ripe, which is usually indicated by their colour. Harvest before the colder months, as chillies need warmth to ripen properly.
Remember to pick your chillies regularly. This not only encourages more fruit production but also keeps you actively involved in your plants’ growth.
You can harvest and eat immature chillies, but they may be milder in flavour.
