Diseases to Look Out for in Cauliflower
Cauliflower can be susceptible to a variety of diseases, including:
- Clubroot: Caused by the fungus Plasmodiophora brassicae, clubroot results in swollen roots and stunted growth. Ensure proper soil drainage and practice crop rotation to prevent clubroot.
- Downy Mildew: This disease, caused by the fungus Peronospora parasitica, leads to discoloured leaves and reduced yields. Provide good air circulation and avoid overcrowding to prevent downy mildew.
- Black Rot: A bacterial disease caused by Xanthomonas campestris pv. campestris, black rot manifests as V-shaped lesions on leaves. Use disease-free seeds and transplants, and avoid overhead watering to reduce the risk of black rot.
Caring for Cauliflower
To grow the best cauliflower, follow these tips:
- Choose a sunny location with well-draining soil.
- Incorporate compost or well-rotted manure into the soil prior to planting.
- Water consistently to maintain even soil moisture, taking care not to overwater.
- Apply a balanced, slow-release fertiliser at planting time, and top-dress with compost during the growing season.
- Use floating row covers to protect your plants from pests, such as cabbage moths and aphids.
Harvesting Cauliflower
Cauliflower is ready to harvest when the head is firm and tightly packed. The size can vary depending on the variety, but most are ready to pick when they reach about 15-20 centimetres in diameter. Cut the head off with a sharp knife, leaving a few leaves attached to protect it during storage.
Storing Cauliflower
Store freshly harvested cauliflower in a cool, dark place with good air circulation, such as a pantry or cellar. Ideally, the temperature should be between 0-4°C with a humidity level of 90-95%. Do not wash the cauliflower before storing it, as moisture can promote rot.
To extend the storage life, you can also:
- Wrap the cauliflower head in a damp paper towel and place it in a perforated plastic bag. This method can keep the vegetable fresh for up to 2 weeks in the refrigerator.
- Blanch the cauliflower florets and store them in airtight containers in the freezer for 6-8 months.
