When houseplants are past their prime, many can easily be replaced by propagation: using cuttings or cuttings. How does it work?

New houseplants without spending money on them? Nothing easier than that. Anyone who wants to make friends or acquaintances happy or who wants to replace their own old plants with new ones can easily achieve this by propagating them. There are different methods depending on the type of plant.

Propagation by cuttings

Propagation by cuttings is an easy way to grow new plants. The most widespread is the propagation by so-called head cuttings, they consist of a shoot tip with a stem and a few leaves. Most plants (e.g. ficus species, poinsettia, money trees, rubber trees) can be propagated in this way. Cut shoots can first be placed in a water glass or planted directly in the ground.

Root formation in the water glass

After about two to three weeks, the cutting will form new roots.

One possibility is to cut off a ten centimeter long, non-woody shoot from the mother plant and place it in a glass of water. Remove any flowers, buds and some of the leaves. Place the glass in a bright place at normal room temperature. New roots form within about two to three weeks. If the cutting remains in the water glass for too long, the fine roots will form a ball - this should be avoided so that the new plant can grow well. The cutting is then planted in the substrate recommended for its species and watered lightly.

Place the cutting directly in the ground

Cuttings should first be placed in nutrient-poor soil.

Alternatively, it is possible to stick the cut shoots directly into moistened soil. This should be low in nutrients so that strong fertilizer cannot attack the tender roots. An admixture of perlite (volcanic glass) or sand is ideal. Place the pot in a light, warm place, but not expose it to direct sunlight. Put a plastic bag over the cutting or the whole pot so that the water does not evaporate too quickly. If new shoots form, the bag can be removed. If the young plants are strong enough, they can be repotted in suitable substrate.

There is also the possibility of propagating plants by leaf cuttings. This works great with African violets, for example. Simply cut off a leaf and stick the stem in the ground. The new plants are best grown in a mini greenhouse. The high humidity gives them ideal growth conditions.

Propagate plants by cuttings

Offshoots, also known as Kindel, arise from the main shoot of the mother plant and are optically its miniature version. Often they already have their own roots. In particular, pineapples such as bromeliads or succulents, but also the popular green lily, for example, form such offshoots.

The offshoots of the green lily look like miniature versions of the mother plant.

Once the cuttings have developed some well-developed leaves, they are large enough to be severed. To do this, cut as close as possible to the mother plant with a sharp knife disinfected with alcohol, without damaging it. Put the offshoot in a pot with potting soil, press it down carefully and water it only lightly. During the entire growth phase, the plant should only be watered moderately so that the roots do not rot. The room temperature should not be below 19 degrees and the young plant should not get direct sunlight at first.

In the case of succulents, wait a few days after separating the children until the cut surface has dried. Then simply place the offshoot in a suitable substrate.

Propagate fuchsias with cuttings
