Ginger

A genuine but niche UK project: ginger needs sustained warmth above 15°C for its whole eight to ten month growing season, so it only works in a heated greenhouse, conservatory, or a committed sunny windowsill, never outdoors. Plant a fresh rhizome piece in spring and dig your own knobbly, intensely flavoured ginger by late autumn.

Sowing Guide

What you'd find on the seed packet

Sow Depth

2–3cm, growth bud facing upwards

Spacing

One rhizome piece per 20–25cm pot

Germination

4–8weeks to first shoots at 25–28°C: cooler spots are much slower and less reliable

Thinning

Not applicable: grown as a single rhizome per pot

Grower's Note

Choose a plump, unwrinkled rhizome piece with at least one visible growth bud ('eye'), ideally from a specialist supplier rather than a supermarket root, which may be treated to prevent sprouting. Soaking overnight before planting can help.

Recommended Varieties

Named UK-supplier varieties are rare: most home growers use an untreated culinary rhizome sourced from an ethnic grocer or specialist online supplier rather than a named cultivar.

Watch Out For

Needs sustained warmth above 15°C all year round: this is a heated-space-only crop in the UK, unlike anything grown outdoors or in an unheated greenhouse

Waterlogged compost rots the rhizome fast: use a free-draining mix and a pot with generous drainage holes rather than keeping it permanently wet

Shoots are slow to appear and easy to mistake for a failed rhizome: growth can take several weeks even in warmth, so resist digging it up to check

Common Questions

About growing Ginger in the UK

Can I grow ginger outdoors in the UK?

No. Ginger needs sustained temperatures above 15°C for its entire eight to ten month growing season, so UK gardeners can only grow it under glass: a heated greenhouse, conservatory, or a warm, bright windowsill indoors.

How much ginger will I actually get?

Modest amounts. Expect roughly 200–400g of fresh rhizome from a single piece planted in spring, harvested the following autumn. It's a rewarding project rather than a way to stock the kitchen.

Can I use a supermarket root to start ginger?

You can try, but supermarket ginger is sometimes treated to stop it sprouting, so success is inconsistent. A fresh, plump piece with visible growth buds from an ethnic grocer or specialist supplier gives more reliable results.

When is ginger ready to harvest?

From late November, once the foliage begins to yellow and die back, roughly eight to ten months after planting. Lift the whole clump carefully and cure the harvested rhizome in a warm, airy spot for a few days before storing.
