How to Grow Spring Onion Ishikura Seeds: Your Complete Guide
When and Where to Sow
Begin from February to March. Use modules, sowing 4-5 seeds per module. Cover them lightly with vermiculite or compost and maintain a temperature of 14°C.
Aim to sow in April. Make shallow drills 1.5cm deep and space the rows 30cm apart.
What to Do Next
No thinning is needed. In April, move these modules to a cold frame to prepare for outdoor planting.
These can be pulled and used as needed.
Maturity and Harvesting
Expect your harvest around 12 weeks after sowing. The onions are versatile and perfect for salads and stir-frys.
This variety is excellent for successional sowing.
Plant between slower-growing vegetables to make the most of your space.
