When to plant spring onion in Mortlake
- Sow in the ground: mid Feb to early NovMortlake area, temperate oceanic
Worked out from 30 years of climate records for Mortlake. Microclimates vary: frost hollows and hills run later.
A quick, easy onion grown for green stems rather than bulbs, ready in 8 to 10 weeks. Sow little and often almost all year in Adelaide. Bunching (Welsh) types can be cut again and again or left to form clumps.
