Care at home

Reproduction

Dorstenias are usually propagated by seeds or cuttings. Seeds germinate easily at a temperature of 21 ° C; crops should be covered with a plastic cap or glass to retain moisture. 

Temperature for succulent

A very heat-loving species, easily enduring summer heat. Bushes that have fallen into a state of rest can be kept at normal room temperature.

Lighting

Most species require fairly intense lighting. 

How to care

The flower adapts to a wide range of growing conditions. In the summer heat, it is advisable to take the bushes outside. In this case, you should gradually acclimatize the succulent to new lighting and air temperature conditions. This process should take about a week or two. Dorstenia can shed its leaves in the fall; in most cases, this is a natural process that does not cause concern. Plants that are dormant in winter should be placed in a well-lit place.

Substrate

Nutritious and well-drained soil. 

Dorstenia foetida

Feeding

Dorstenias need feeding a little more than other succulents. During the period of active growth, use fertilizers with a low nitrogen content, diluted to 1.4 times the recommended dose every 2 weeks. 

Flowering time

Summer. 

Air humidity

Spray periodically during the warm season in the morning. 

Watering

In hot and dry weather in summer, watering should be abundant and fairly frequent. Before each watering, the soil should be almost completely dry. Actively growing specimens should not be subjected to periods of prolonged drought, otherwise the tree will shed its leaves to conserve moisture. In winter, just try not to overdry the soil. The appearance of new shoots in the spring should be a signal to begin regular watering.

Varieties:

Dorstenia foetida

 A beautiful plant, sometimes reminiscent of palm trees, with thick, erect stems that are often branched at the base.

At the tops of the shoots there is a crown formed by simple, dark green, oblong-oval leaves. A conical caudex is often formed at the base of the stems. What might be mistaken for flowers are actually fruiting bodies - they are round, green, orange or pink.
