Seed & start
Pre-culture recommended
Start indoors / cold frame first, transplant into the raised bed later.
Stachi's tip
Leek is robust and winter-hardy. Plant it deep — the white shaft develops from soil contact. Top companion to carrot (mutual pest protection). Harvest August into deep winter.

Harvesting and drying onions: when to pull them — and how to store them for months
My neighbour Frau Schneider pulled her onions too early last year. Instead of drying out, they started to rot. The difference between an onion that keeps until February and one that turns mushy in October comes down to a single sign.
Garlic from the raised bed: how to tell it's truly ready — and how to store it for a year

Pre-growing for the autumn bed: what you should already be sowing in June so the autumn doesn't stay empty
In June the bed is full and autumn feels far off. That's exactly the trap. What you pre-grow now, you harvest in October — and what you miss, you'll simply do without.
