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.

Articles about this plant
Celeriac: get it out of the ground before the first hard frost hits
With parsnips and carrots, the rule is: wait for frost. With celeriac, it's the opposite. Leave it in the ground too long and you risk soft, rotten spots on the bulb – here's what to watch for on timing.
Brussels sprouts: top the plant now so the sprouts fill out
Your Brussels sprout plants are tall, but the sprouts along the stem stay small and loose? One cut in late September stops the upward growth and sends all the energy into the buds. Now is exactly the right moment for it.
Planting shallots in autumn: the small bulb that earns its keep
Shallots are probably the most overlooked autumn task in the raised bed. Plant now, harvest next July — with barely any effort and no green thumb required.
The September switch: clearing summer crops and planting your autumn bed
September is the month of the big changeover. Tomatoes are winding down, courgettes are getting tired — and the space they leave behind is some of the most valuable growing ground of the whole year.
Planting garlic in September: how to start now for the 2027 harvest
Garlic is one of the few crops where you do the work in autumn and collect the reward in summer. Plant now and you'll have large, aromatic bulbs by next July — or wait until October if you prefer the sweet spot.
Earthing up leeks: the trick for white shafts in your raised bed
