FAQs

How many seeds are in the pack?

Each pack contains approximately 60 seeds.

Does this variety need a lot of space?

No, it is a compact variety reaching 600 mm in height, making it ideal for patios, raised beds, or small plots.

Can I grow this in a pot?

Yes, it is well-suited for container gardening as long as the pot has adequate drainage and size.

Is it frost-hardy?

While robust, it is an annual typically grown during the warmer growing season; protect young plants from late spring frosts.

How do I harvest the side shoots?

Once the main head is removed, continue to water and feed the plant; the side shoots will emerge from the leaf axils and can be cut when they reach a usable size.

Troubleshooting

Plant looks stunted or wilts after transplanting

The roots were likely disturbed. Always transplant with the original soil ball intact or use biodegradable pots.

Leaves being eaten by insects

Apply fine horticultural netting over the crop to create a physical barrier against caterpillars and cabbage white butterflies.

Main head flowering prematurely (bolting)

Ensure consistent watering and check if the plant is receiving too much heat. Applying mulch can help keep soil temperatures cooler.

Setup, Compatibility & Care

  1. Sowing: Sow seeds in seed trays or direct into the soil in spring. Because this variety dislikes root disturbance, using biodegradable pots is recommended so you can plant the entire pot directly into the ground.
  2. Sunlight: This variety requires a full sun position to thrive.
  3. Pest Protection: Brassicas are highly attractive to local wildlife. Use fine-mesh garden netting or bird scarers to protect young leaves from hungry insects and birds.
  4. Spacing: If planting in rows, space plants approximately 450 mm apart to ensure adequate airflow.
  5. Maintenance: Water consistently to keep the soil moist, especially during hot, dry spells, as this prevents the plant from 'bolting' or going to seed prematurely.
