How To Grow Ginger on the Windowsill

Ginger brings a spicy heat to the kitchen, spices up every dish and fights all future colds. However, the inconspicuous tubers, especially in organic quality, can quickly become expensive. These instructions show how you can easily plant and propagate your own ginger in the future.

Plant ginger: Healthy super tubers

Colloquially, the thickened parts of the ginger plant that grow underground are called tubers or sometimes roots. Strictly speaking, however, they form an underground shoot axis system and are called rhizomes in botany.

As a spice or culinary herb, the ginger rhizomes provide a dynamic spiciness in all kinds of dishes, either mild or powerful depending on the dosage. In Asian countries, the power of ginger has been known for many millennia: in Cambodia, India and Vietnam, ginger is an indispensable part of the cuisine. The health-promoting effect of ginger has also been proven. Its consumption can inhibit the proliferation of bacteria and viruses, promote blood circulation, strengthen the immune system and also improve digestion.

Ginger can also provide vitamins and minerals: Vitamin C, calcium, magnesium, potassium, sodium and phosphorus are contained in the rhizomes.

Planting ginger: Instructions for propagation

You can easily cultivate ginger on your own windowsill – cheap and uncomplicated. You only need a little equipment and a little patience.

What you need:

Organic ginger tuber(s)
Filled water glass
Pot(s) (at least 25-30 centimetres high, with drainage holes)
Sharpened knife
Nutrient-rich, permeable and preferably lime-free substrate

And this is how you proceed:

Start planting in spring, as this is when the ginger is at the beginning of its growing season.
Several pieces can be taken from a ginger rhizome, each of which can then develop into an independent plant.

Remove the pieces with a sharp and clean knife. It is important that there is a sprouting bud (a so-called “eye”) on each piece taken out. The buds on the ginger can be recognised as small, usually roundish bumps. Each piece should be about five centimetres long.

Before planting, place the ginger pieces in a glass of water for at least 12 hours.
Loosely fill the planter with the substrate. Leave a watering margin of at least one centimetre.
Place two to four ginger pieces in each pot so that the eyes protrude slightly at the top.
Finally, water carefully - that's it.

After planting ginger: The right care

Until the first ginger harvest, a little patience is needed, as well as good care, of course. After planting, the ginger must stand in a bright, warm place. The substrate should never dry out completely over the next few weeks until new green shoots appear. However, it must not get too wet either, otherwise the rhizomes could rot.

Tip: Use a spray bottle to dose the amount of water more evenly.

Harvesting ginger at last

Several months can pass before the tubers are finally ready for harvesting. While the above-ground shoot forms several long shoots, the underground sections continue to grow and develop into complete rhizomes again.

As soon as the plants show the first yellow discolouration above ground, you should gradually reduce the watering and finally stop it altogether. Then the harvest time has finally come. It is up to you whether you harvest the tubers as a whole or continue cultivating a part of them.
