Causes of cutting failure

The reasons for cutting failure are as follows:

1, the branch itself.

Need to choose, annual cuttings, for breeding. It's easy to survive. The rooting rate of annual robust branches is more than 50% higher than that of two-year branches.

The growth potential of shoots is relatively easier to form adventitious roots than perennial branches. If you choose branches with buds for cutting propagation and let them bloom without treatment, most of them will end in failure.

2. Their own conditions affect rooting.

Some cuttings contain substances that are not easy to take root, such as organic acids, resins, tannins, etc., which will affect the occurrence of their own rooting. These substances will prevent the ability to take root.

Reduce the formation of plant growth hormone. Generally, the base of cuttings is soaked with rooting powder solution.

On the one hand, it is helpful to remove the organic acids remaining on the surface of the incision and inhibit the substances that affect rooting. On the other hand, using rooting powder to stimulate the scion is easier to take root and improve its vitality.

3. Effect of moisture on cutting.

If the cutting seedbed is too dry. Seriously affected the water supply. Water is the source of life. The new roots germinated at the base of cuttings absorb water first.

If after cutting. Water can not be replenished due to a large amount of evaporation, and the activity of new roots decreases, which is easy to cause scion withering and cutting failure. In order to improve the rooting survival rate of scions, measures such as heat preservation, moisture preservation and shading should generally be taken. Reduce or reduce the side effects caused by transpiration.
