How to water
As for the correct irrigation of the Lewisia, it is important to proceed during the period of vegetative activity, therefore during the hottest months of the year. The plant does not need to be irrigated in autumn or winter because it suspends the vegetative activity altogether. The wetting must be kept constant throughout the flowering period and must be gradually reduced until it is suspended when the loss of flowers begins to be noticed. Generally, during the months of vegetative activity of the Lewisia, one proceeds with the baths once every two weeks. It is important to always check the substrate before proceeding, in order to avoid the formation of water stagnation and consequently cause root rot. As far as irrigation water is concerned, Lewisia has no particular needs.
How to cure
Regarding the correct exposure of Lewisia, it is necessary to place the plant in particularly sunny areas. It is good that our Lewisia can enjoy direct sunlight for several hours a day in order to achieve copious flowering. However, an important trick is to place the plant in a place sheltered from the rain as Lewisia absolutely does not tolerate humidity. As far as temperatures are concerned, the plant is able to withstand even the harshest climates and the lowest temperatures as during the winter months it completely suspends its vegetative activity. For multiplication, it is advisable to proceed with cutting or seed, placing the sprouts directly in some boxes to be kept in a drawer with soil composed of peat and sand. The sprouts will be planted once the rooting has taken place.
How to fertilize
Proper Lewisia fertilization occurs during the flowering period, therefore during the hottest months, and should be suspended completely with the arrival of autumn. We recommend the use of a slow release granular fertilizer that contains the fundamental chemical substances such as: phosphorus, nitrogen and potassium. The fertilizer must be sprinkled all over the ground. It is good to fertilize about once every two months. The best soil for Lewisia is loose soil that is rich in sand and peat. It is also important that this substrate is well drained and has a pH that is around 6.8-7. An important trick is to combine the soil with gravel that can help drain water. If the Lewisia was cultivated in pot, the soil must be completely renewed every time we proceed with the repotting.
The Lewisia does not particularly fear the attack by small parasites. Rather, it is good to check for the presence of snails or slugs, especially during the spring months that correspond to the vegetative resumption of the plant. In fact, these insects feed on the leaves of Lewisia causing holes. The plant suffers very easily from root rot. It is easy to generate this pathology every time we proceed with excessive wetting of the soil. The root rot quickly leads to the death of the plant. As for the climate, Lewisia does not fear the colder temperatures. This plant, in fact, completely loses its leaves and flowers during the winter months in order to protect itself. Rather, the Lewisia is more afraid of rain and is therefore recommended to store it in a sheltered place.
