The plants of this genus prefer sunny locations, but possibly semi-shady during the hottest hours of the day, especially in the summer; they can bear temperatures close to -7-8°C, but in areas with very harsh winters it is advisable to position them in a place sheltered from the wind. They can resist even in environments not ideal for them, but their development will be modest and the plants will not be lush.

Watering of the corokia should be done according to the period; from March to October it is advisable to water quite regularly, always waiting for the soil to dry completely between one watering and the other; avoid leaving the soil dry or soaked in water for a long time; during the cold season water only in case of prolonged periods of drought. It is important to avoid water stagnation that could cause the base of the plant to rot.
Corokia plants prefer loose soils, rich in organic matter and very well drained; let’s avoid planting in excessively gravelly and dry soil or in very heavy and compact soil. An important factor for the correct development of the plant is to check that the soil has a correct degree of humidity, verifying that the soil is not too dry and compact and, at the same time, is not water soup, a factor that could accelerate the appearance of problems and infections by fungi or root rot.
The multiplication of this variety of plants takes place by seed in spring, but this method of propagation often does not give the desired results, because most of the corokias on the market are hybrids and therefore from seed you do not always get plants identical to the mother plant, which is why the corokia generally propagates by semi-woody cutting, in autumn.
Corokia: Parasites and diseases
Corokia plants are quite resistant but can be affected by parasites and diseases that undermine their health. These plants fear scab, rust and aphids, which often attack young leaves and buds. In case of diseases and parasites, it is advisable to intervene quickly, using solutions that lead to definitive results, to ensure that the plant can grow healthily. Many products are available on the market that can help to effectively solve these problems.
