Lemerocereus: Home Care, Replanting And Propagation

A plant like Lemerocereus is directly related to the cactus family and can be found in the wild in South Africa. It was named after the botanist Charles Lemaire. This famous Frenchman lived in the 19th century.

In the wild, this plant has the appearance of a polyhedral column, which reaches a height of 15 meters and a diameter of 50 centimeters. This cactus branches out in the middle of the stem, making it look like a candelabra.

Many flower growers would like to have such a plant in their collection, but it is rather capricious and prone to various diseases. So it is quite difficult to grow Lemaireocereus at home.

The most common choice for growing in the apartment is Lemaireocereus marginalus (Lemaireocereus marginatus). On a fairly strong stem there are clearly distinguished ribs, on which the whitish dense bristles are located. Spiky straight spines reach 10 centimeters in length.

Mature and old specimens have cream or white flowers that reach 7 centimeters in length. After flowering, edible prickly soft fruits with an oval shape appear.

Possible problems

  1. Stem ends are dry and there are spots of soft rot - this is due to overwatering. Cut away the affected areas and make sure the cactus is well cared for (ventilate the room regularly, do not over water and keep the room temperature as high as necessary).

  2. Soft brownish spots on the cactus surface- infected by stem rot. Remove the affected areas by cutting them out and treat the substrate with carbendazim solution.
  3. Fluffy whitish spots have appeared on the surface - powdery mildew worms have settled in. If the infestation is small, it will be enough to wash the problem area with a wet rag. But if there are many pests, you will need to treat with a suitable product.
