Turmeric plant

Ideal environment

Turmeric is a tropical plant very similar to Lotus Flowers. The ideal environment to make it grow strong and lush is hot and humid. In the warmer months it should be watered regularly, without ever creating stagnant water in the saucers, which could promote root rot. If the temperatures are particularly hot, it is advisable to spray the leaves of the plant once a day. At the beginning of autumn, when its leaves begin to turn yellow and fall off, watering must be suspended to encourage complete drying of the leaves. The plant fears frost and intense cold. For this reason it will be necessary to put it in the fresh air, in the winter months, in a cool and dry environment, where the temperature never drops below 15 ° C. Watering will be resumed in spring, when new shoots will begin to be seen in the ground.

Growing tips

There turmeric plant prefers bright environments, without exposure to direct sunlight. The ideal temperature is around 20/25 ° C. In summer the turmeric can also be placed outside, but in the colder months it must be brought back home, so as not to expose it to temperatures below 12 ° C. The turmeric rhizome can be planted at any time of the year, although it is often preferred to plant it in a vase during the spring, to allow the plant to develop throughout the summer. In winter the turmeric will tend to lose its leaves and dry up. We must not be alarmed: it is a natural process in its life cycle and in spring it will return to germinate. If you like to use turmeric as a spice in the kitchen, it is possible to harvest the rhizome in winter when the species is dry. This looks like the root of the ginger, but inside it has the characteristic orange yellow color that distinguishes it.


Since turmeric is grown mainly in pots, as a houseplant, it is necessary to guarantee the earth that surrounds it the right amount of substances necessary for its growth. From the beginning of spring, when the first shoots appear, until late autumn, when the plant will begin to gradually lose the leaves, it is necessary to intervene every two weeks with a liquid fertilizer to be dissolved in the water of watering. The chosen fertilizer must guarantee the plant the right amount of nitrogen, phosphorus, potassium, iron and magnesium. In spring, on the occasion of repotting the plant, it is possible to take small portions of the rhizome that have well-developed roots and proceed with the multiplication of the turmeric. The plant does not need particular pruning. It will only be necessary to take care of removing those branches that, broken or dry, could become a vehicle of diseases for the plant.

Turmeric plant: Diseases and pests

There turmeric plant it is hardly attacked by parasites. However it is possible to notice small greenish-white insects that move on the leaves. They are the aphids, or plant lice. In this case it is necessary to intervene with a good insecticide product, which can be purchased in specialized centers or in nurseries. If, on the other hand, the leaves tend to turn yellow and then curl up, it could be an attack of the red spider. If it is a circumscribed episode it will be sufficient to increase the nebulization on the leaves (the spider mite develops more in the absence of humidity). If, on the other hand, the infestation is extensive it will be necessary to intervene with an acaricidal product. A more natural remedy is to wash the leaves with a cotton pad, previously wet and treated with Marseille soap. Then rinse the plant very well to remove all traces of the product.
