The rubber tree (Ficus elastica), which can grow up to 2 meters tall in our country, is an indispensable evergreen houseplant. It belongs to the fig family and has its origins in East India and Indonesia. It belongs to the mulberry family. Its leaves are usually dark green or yellow variegated and its bark secretes a latex-like secretion when it is injured. This can be used to make rubber, hence the name rubber tree.

Everything about caring for the rubber tree (Ficus elastica)

This sturdy houseplant can reach a considerable height, so in the long term it will need a stake to which it can be attached in order to maintain an upright shape. It is important to note that the leathery leaves often collect dust and therefore need to be wiped down regularly with a damp cloth.

The right location for rubber trees

Rubber trees thrive in a bright location, but they should be protected from direct sunlight as this can cause the leaves to burn. A location with indirect light or light partial shade is also ideal. Temperatures of around 18 degrees Celsius are optimal for the growth of the rubber tree. However, drafts should be avoided!

Repotting rubber plant: When and how?

The rubber plant should be repotted every few years, preferably in spring when rapid growth begins again. Be sure to choose a pot that is slightly larger than the previous one to allow room for root growth. When repotting, it is important to gently loosen the root ball and ensure that the plant is at the same height in its new pot as before.

The right substrate

A loose, well-drained soil that is rich in nutrients is suitable for the rubber plant. A mixture of commercially available, but still high-quality potting soil and perlite is ideal for avoiding waterlogging and at the same time ensuring good air circulation around the roots.

The rubber tree can be propagated by cuttings. To do this, cut off a healthy shoot that has at least two pairs of leaves and place it in a glass of water. Place the cutting in a warm, bright place.

What to do if there are pests on the plant?

Pests such as spider mites, aphids or scale insects can occasionally attack the Ficus elastica. If an infestation occurs, it is important to act quickly to prevent the spread. One option is to treat it with neem oil, which is especially suitable for houseplants. The pests should also be wiped off with a cloth sprayed with water or rinsed off with a jet of water beforehand.
