You can cause chilli plants to flower and flourish by supplementing nutrients and controlling environmental conditions. Each flower on a chilli plant has the potential to grow into a complete chilli pepper. Your chilli harvest will increase with each healthy blossom you are able to grow on a pepper plant. With adequate sunlight, water, warmth and nutrient-rich soil, a chilli plant will have everything it needs to produces a selection of healthy flowers every growing season.

- Rain water or tap water
- Sun shade (optional)
Fertilise the chilli plant twice a week according to the manufacturer's direction for dilution and application. Using a balanced nitrogen, phosphorus and potassium fertiliser promotes plant growth without overriding flower bud production. Quickly pull any visible weeds during the fertilisation process to reduce plant competition in the surrounding area.
Water the chilli plant every other day with rainwater or tap water that has been left in an open container overnight. The soil should be constantly moist but never wet. Watering sticks and meters can be helpful in maintaining proper moisture levels in the soil. Airing out the tap water allows the chlorine use to treat municipal water supplies to evaporate and makes the water safe for use on plants.
Cover the soil surrounding the plant with a layer of bark or other natural mulch. The layer of mulch helps the soil hold in moisture and heat, reduces weed growth and releases trace nutrients into the earth as it decays.
Create an optimum flowering environment by maintaining daytime temperatures right around 23.9 degrees Celsius and nighttime temperatures around 18.3 degrees Celsius. Temperatures falling more than -12.2 degrees C out of this range will deter flower growth and may cause formed flowers to fall off the plant.
Control the sun exposure to meet the light needs of the specific variety of chilli plant you are growing. Many spicy chilli plants do well in full sun, while some sweet varieties may require partial shade to flourish.
Tips and warnings
- With plants, if a little is good, it does not mean more would be better. Avoid over watering and over fertilising or you will have a dead chilli plant without any flowers.
