Growing Tips for Durban

Starting Seeds Indoors for a Great Start

Many plants, like lettuce (July to January) and Swiss chard (June to September), benefit from starting seeds indoors. This ensures a strong start and protects young plants from extreme conditions. Ensure you use a fine seed compost and only lightly press the seeds in.

Choosing the Best Location and Soil

Most vegetables, like onions and garlic, love a sunny, warm spot. Ensure you have loose, humus-rich soil that retains moisture well but doesn't get waterlogged. Good soil preparation with compost is crucial here.

Proper Watering is Key

Plants like spinach (summer), courgettes, and aubergines have high water needs and require very moist, but not waterlogged, soil. Especially during drier periods, ensure a consistent water supply to avoid stress and ensure good yields.

Nutrient-Rich Soil for Heavy Feeders

Heavy feeders like tomatoes, courgettes, aubergines, and strawberries need plenty of nutrients to thrive. Regularly enrich your soil with compost or organic fertiliser to ensure a continuous supply. This promotes vigorous growth and abundant harvests.

Common Pests & Diseases

•

Identifying and Combating Aphids

Aphids are small, often green or black insects that gather on young shoots and the undersides of leaves, sucking plant sap. Rinse them off with a strong stream of water or introduce beneficial insects like ladybird larvae. A soapy water solution can help with heavy infestations.

•

Keeping Snails and Slugs in Check

Snails and slugs can cause significant damage, especially during wet periods, by eating leaves and young plants. Regularly pick them off, put out slug traps, or use iron phosphate-based slug pellets, which are harmless to pets and hedgehogs. A barrier of sawdust or eggshells can also help.

•

Spotting Spider Mites Early

Spider mites are tiny pests that form fine webs on the undersides of leaves and cause them to turn yellow-brown. Increase humidity, as they love dry conditions, and regularly mist your plants with water. Neem oil or a potassium soap solution can help control infestations.

•

Preventing Fungal Diseases

Fungal diseases like powdery mildew or rust often appear with high humidity. Ensure good air circulation between plants and avoid overhead watering, especially in the evening. Strengthen your plants with plant tonics or use organic fungicides if needed.
