FAQs

When is the best time to sow Kale 'Yurok' F1 seeds?

You can sow indoors from early spring onwards, or directly outdoors from mid-spring to early summer. The key is to transplant them to their final positions during the summer months for autumn/winter harvest.

How much space do the plants need?

Plants should be spaced approximately 60cm (24 inches) apart to allow for their full growth and yield.

How do I protect my kale from pests?

Using fine netting is recommended to prevent Cabbage White Butterflies from laying eggs on the leaves. Regularly inspect plants for any signs of pests.

Can I grow this kale in pots?

Yes, due to its compact nature, 'Yurok' F1 can be grown successfully in large containers, provided they offer adequate depth and good drainage.

What is the 'H4 hardy' rating?

H4 hardy indicates a high level of resistance to cold temperatures, meaning the plants can withstand significant frost.

How long does it take for the kale to be ready for harvest?

Harvesting can typically begin from early autumn and continues through to late winter, depending on when the seeds were sown and planted out.

What makes Cavolo Nero different from other kales?

Cavolo Nero, also known as black kale or Tuscan kale, typically has flatter, darker leaves with a slightly sweeter flavour compared to the more common curly kales.

Troubleshooting

Seedlings fail to germinate

Ensure seeds are sown at the correct depth and the compost remains consistently moist and warm (10-15°C).

Plants are weak or stunted

Check for adequate sunlight, consistent watering, and soil fertility. Ensure proper spacing (60cm apart).

Holes in leaves

Apply netting to protect plants from Cabbage White Butterfly. Check for other common brassica pests.

Yellowing leaves

This can indicate over or under-watering, or nutrient deficiency. Adjust watering schedule and consider feeding with a balanced liquid fertilizer if needed.
