Chillies are susceptible to a range of pests and diseases that can affect their growth and yield. Here are some common issues to watch out for:
Pests
– Aphids: These small insects feed on the sap of the plant, causing leaves to curl and distort. They can also transmit viruses to the plant.
– Whiteflies: These tiny, white insects can quickly infest chilli plants, sucking sap from the leaves and causing them to yellow and wilt.
– Spider mites: These pests thrive in hot, dry conditions and can cause stippling and webbing on the leaves of chilli plants.
Diseases
– Powdery mildew: This fungal disease appears as a white, powdery coating on the leaves and stems of the plant, leading to stunted growth and reduced yield.
– Blossom end rot: This condition is caused by a calcium deficiency in the plant, leading to dark, sunken spots on the bottom of the fruit.
– Grey mould (botrytis): This fungal disease can affect chilli plants, causing a grey, fuzzy growth on the leaves and stems.
To manage these pests and diseases, it’s important to practice good garden hygiene, including regular removal of dead or diseased plant material. Additionally, using natural predators, such as ladybugs, can help control aphid populations. For fungal diseases, proper spacing and ventilation can help reduce the risk of infection. In severe cases, organic or chemical treatments may be necessary to control pest and disease outbreaks. Regular monitoring of your chilli plants is key to catching and addressing issues early.
6. Pruning and harvesting
After your chilli plants have grown to about 20cm tall, it’s important to start pruning them to encourage bushy growth. Pinch out the growing tips to promote lateral branching and more fruit production. This will also help to prevent the plants from becoming too leggy and top-heavy.
Pruning tips:
– Use clean, sharp scissors or pruning shears to avoid damaging the plant
– Pinch off the tips of the main stems just above a leaf node
– Remove any small, weak or damaged branches to focus the plant’s energy on producing larger, healthier fruits
Once your chillies have reached their mature color, it’s time to start harvesting. The best time to pick your chillies is when they have reached their full size and have developed their mature color. For milder flavor, pick the chillies while they are still green. If you prefer a hotter taste, allow the chillies to ripen to their mature color, whether it’s red, yellow, orange, or any other hue specific to the variety you are growing.
Harvesting tips:
– Use clean, sharp scissors or pruning shears to avoid damaging the plant
– Cut the chillies from the plant, leaving a small stem attached
– Handle the chillies carefully to avoid damaging the delicate skin and releasing the capsaicin, the compound that gives them their heat
By following these pruning and harvesting tips, you can ensure that your chilli plants stay healthy and productive, providing you with a bountiful harvest of flavorful and spicy chillies.
7. Overwintering tips
After the chilli plants have finished producing fruits, it’s important to prepare them for overwintering. Here are some tips to help your chilli plants survive the colder months:
Protect from frost
As chilli plants are tender, they will not survive the winter outdoors. Before the first frost, bring your chilli plants indoors to a warm, well-lit area. This could be a sunny windowsill or under grow lights. Make sure the plants are protected from drafts and cold temperatures.
Reduce watering
During the winter months, chilli plants go into a period of dormancy. This means they require less water. Reduce watering frequency, allowing the soil to dry out between waterings. Overwatering during the winter can lead to root rot and other issues.
Prune and tidy up
Before bringing your chilli plants indoors, give them a good prune to remove any dead or diseased foliage. This will help the plants focus their energy on new growth during the winter. Tidy up the soil surface and remove any debris to prevent pests and diseases.
Provide adequate light
Indoor conditions may not provide as much light as the plants are used to outdoors. Consider using grow lights to supplement natural light and ensure your chilli plants receive at least 12-16 hours of light per day. This will help them stay healthy during the winter months.
By following these overwintering tips, you can help your chilli plants survive the winter and prepare them for a successful growing season next year.
