FAQs
When is the best time to sow Cabbage April?
Sow indoors from March to May for a summer harvest, or July to August for an overwintered spring harvest.
How deep should I plant the seeds?
Sow the seeds at a depth of 13mm (1/2 inch).
Can I grow these in pots?
While typically grown in the ground, they can thrive in large containers provided they have enough room to reach their 30cm height and 40cm spread.
How long does germination take?
Under ideal conditions of 20-25C, germination typically occurs within 4-7 days.
What is the benefit of using vermiculite?
Covering with vermiculite helps maintain consistent moisture levels and temperature around the seeds during the germination process.
Are these plants frost hardy?
Once established, they are hardy annuals, but young seedlings should be protected from frost until they are large enough to transplant.
Troubleshooting
Seeds failing to germinate
Ensure the temperature is consistently between 20-25C (68-77F) and the compost remains moist but free-draining.
Plants wilting after transplanting
The plants may not have been fully acclimatized. Ensure a gradual 7-10 day hardening-off period before moving to the permanent garden bed.
Yellowing or stunted leaves
This often indicates a nitrogen deficiency. Supplement the soil with a nitrogen-rich organic fertilizer.
