How to judge whether the cutting is successful or not

If the cuttings can stay bright green for a long time, it means that the plants grow normally and the cuttings are successful. Otherwise, it will not succeed. Basically, the cuttings can grow roots in two weeks without dehydration and wilting.

The bed can be cut according to local conditions, and all kinds of pots, wooden boxes, plastic boxes, fish tanks and so on can be used. When this container is inserted into the bed, the lower part should be padded with drainage, and if there are holes or cracks in the bottom, less drainage can be put. Some greenhouses have brick cutting beds, which can be cut with a little trimming.

Sometimes, in order to rescue diseased plants, it is necessary to use a cutting bed with a bottom temperature in any season. Heat source is buried in the substrate with electric heating wire or electric heating clip, so that the temperature of the substrate is 3-6℃ higher than that of air, and the substrate takes root faster. Some easy-to-take-root varieties, such as longevity flowers of Sedum family and some cactus varieties used as rootstocks, can be directly inserted into the sand in greenhouses or plastic greenhouses.

Extended data

A complete plant needs at least roots, stems and leaves. The way that some organs grow other parts is called cutting, which can be divided into leaf cutting, bud cutting, leaf bud cutting, branch cutting and root cutting according to different parts. Due to the lack of root system, water stress is easy to occur during cutting, so it is necessary to pay attention to the maintenance of air humidity and remove most leaves if necessary to avoid evaporation.

Grafted into two plants, through the process of tissue regeneration, combined with each other. The part that provides the root system is called rootstock, and the branches grafted on it are called cuttings. In addition to the compatibility of marriage, we should also pay attention to the close combination of the combined parts, avoid shaking, and moisturize the cut parts.

Cutting and grafting are asexual propagation methods, and new individuals can retain the characteristics of their parents, which is suitable for rapid propagation of varieties. The difference is that the root system of cutting seedlings is formed by the variety itself, while grafting uses the roots of other different species or varieties (rootstocks).
