TIPS FOR CUTTINGS

For a good cutting, you have to take a piece of stem from a « mother-plant » which has at least a leaf or half a leaf, and a bud. This cutting has to be put into breeding ground. You can say that it is “working” when the roots showed up and that it is starting to develop autonomously, forming indeed a new generation.

Then, you can multiply plants indefinitely. The cuttings have to be taken from mother-plants which are healthy and well-established. In general, the cutting has to be from 5 to 7.5cm and to have a good meristem (bud).

Before planting buds, you have to wash a length of 2.5cm on its inferior part. No part of the leaf or petiol should be buried in the ground.

Using cutting hormone can facilitate the rooting process. Once the cutting is wet, shake it slightly to get rid of the extra powder. Than plant it immediately in an adequate substrate. It would have to be watered before with a hole of 2.5cm depth. After putting the cutting in, gently pack the breeding ground to ensure its stability.

The rooting has to be quickly stimulated because the cutting keeps on losing water through the leaves and don’t have any root to replace this water. The cutting’s spray will increase the relative humidity level and lower the leaves and air temperature.  It can then allow roots multiplication while maintaining light on the plants. The ground temperature has to be kept around 18° and 21°C, and the air temperature has to be between 21°C during the day and 16°C during the night. Using the mini-greenhouses makes it easier to keep a good level of hydrometric. 

Roots should appear on the pots’ walls and it is a good thing. At the same time, rooting buds will probably get installed inside the pot. They are at the origin of the final roots.

Maybe the plant post will moulder or get green: don’t worry about it, it is perfectly normal and it won’t affect the plant. The biodegradation starts as soon as the plant pot is in a wet place. 

The rooting can be done 10 to 14 days after the transplantation, in ideal conditions and differing for each plant. If you add twice a strong high-in-phosphorus fertiliser, like 10-52-10, it will help stimulate the rooting once the roots are out. Once the cutting is well expanded, you should choose a suitable fertiliser for the plant you are growing.

The transplantation is a critical moment for a young plant. The conditions in the new environment shouldn’t be too different from the previous one, especially if it is coming from the inside to the outside. In case of need, you can try to “strengthen” the plant progressively getting it used to cold or dry environment.

The plant has to be repotted or in open soil with the pot: you have to be careful because it has to be entirely buried. The transplantation can be compromised if there is still a piece of the pot out in the open.

In order to prevent the shock, the seedlings should be fertilised with a high-in-phosphorus fertilizer like 10-52-10 and of course should be watered correctly.  If you put it twice, it will trigger an increase of the roots and will help the seedlings settle in the garden.
