Ginger is a vegetable plant, but also a condiment. Used to flavor dishes, thanks to its peppery flavor, this rhizome also has medicinal properties. To take advantage of the benefits of ginger and obtain an organic and abundant harvest, it is important to successfully cultivate this Asian plant.
How to grow ginger successfully and get a bountiful harvest?
To grow ginger, you will need rhizomes, not seeds, because ginger does not produce any. The rhizome is an underground stem that bears aerial roots and stems. To obtain an organic harvest, it is important to choose organic rhizomes, which you can find in health food stores. These have not been treated and can therefore easily germinate. These roots meant to be planted must also be vigorous and not withered or stunted. Also, choose rhizomes that contain multiple growths. Your harvest will be more generous.
To grow your ginger in a pot, it is important to choose a large container which is also deep, to promote root development. You can opt for a planter, for example, to accommodate up to 3 ginger rhizomes per container. To promote drainage and prevent root rot, place clay balls in the bottom of the pot. Then fill 3/4 of the pot with a mixture of 2/3 potting soil and 1/3 river sand, then tamp down lightly. Plant the rhizome flat, without pushing it completely into the soil. Part of the rhizome should remain visible. Then water, taking care to do not leave standing water in the saucer.
After planting the ginger, keep the pot in a sunny room and hot avoiding exposure to direct sunlight. Note that ginger is a tropical plant that likes heat around 25°C and constant humidity. Moderate watering is recommended if your ginger has not yet developed its roots, because the slightest excess could cause your plant to rot. Wait for the first leaves to appear and the stems to rise to water the soil more regularly. Indeed, it should not stay dry. However, avoid stagnant water in the saucer or cache-pot.
Ginger grown indoors can be prone to scale insect attack. To avoid this, it is advisable to air your plant as often as possible, provided it is not cold. To do this, keep your pot for a few hours in the garden or on the terrace, especially in summer when it is not cold. In the event of a mealybug attack, soak a cotton ball in alcohol and pass it over the foliage.
When to harvest ginger?
Ginger can be harvested 9-10 months after planting. If you notice that green parts of the plant are starting to dry out, then you can dig up the rhizomes for consumption. To obtain a ginger with a more lemony taste, consider harvesting it after only 6 months of planting.
You can also fragment the harvested rhizomes in order to plant them and obtain a new harvest. However, make sure that each fragment of rhizome contains at least a bud.
That said, by respecting the needs and requirements of ginger, you will succeed in growing this condiment plant, and obtain a generous harvest, even without having a green thumb.
