FAQs

When is the best time to sow Cabbage Kalibos seeds?

Sow seeds indoors from March to May for a late summer and autumn harvest.

What type of soil is best for Cabbage Kalibos?

A fertile soil rich in nitrogen is essential. Prepare the soil in early spring by adding well-rotted farmyard manure. Lime may be needed for acidic soils.

How far apart should I plant Cabbage Kalibos?

Plant cabbages at a distance of 50cm (20") apart to allow adequate space for growth.

How do I protect Cabbage Kalibos from pests?

Use protective netting or fleece to deter birds and insects, and place a collar around the stem of each plant to prevent cabbage root fly attacks.

What are the mature dimensions of Cabbage Kalibos?

Plants typically reach a height of 45cm (18in) and have a spread of 25cm (10in).

Is Cabbage Kalibos good for cooking?

It is best enjoyed raw in salads where its vibrant color is most prominent. The color reduces significantly upon cooking, but it can still be used in cooked dishes for its flavor.

What are the germination conditions?

Seeds require a temperature of 20-25°C (68-77°F) and consistent moisture until germination, which usually takes 4-7 days.

Troubleshooting

Seeds not germinating

Ensure consistent temperature (20-25°C) and adequate moisture. Check that the compost is fresh and free-draining. Germination can take 4-7 days.

Seedlings are leggy and weak

Provide more light once germinated and reduce temperature slightly. Ensure they are not overcrowded.

Plants attacked by birds or insects

Immediately cover plants with protective netting or fleece. Ensure netting is secured around the base.

Holes in leaves

Identify the pest (e.g., caterpillars, slugs). Handpick pests or use appropriate organic pest control methods. Ensure netting is intact.

Plants wilting despite watering

Check for cabbage root fly by gently inspecting the stem base and soil. Use collars around the stem. Ensure the soil has good drainage to prevent root rot.
