Does rain affect the survival after grafting?

Rain affects the survival after grafting.

Rain after grafting is not conducive to survival. In rainy days, there is no sunshine for a long time, which often leads to the growth of mold in callus or affects the survival of grafting. In case of long-term drought, serious water shortage, and untimely watering of rootstocks or scions, it may lead to early defoliation of seedlings and short-term contraction of cambium, which is also not conducive to the development of branches and buds.

Extended data:

Matters needing attention: It is best to choose strong branches with developed periphery, full bud eyes, uniform thickness and no pests and diseases as scions, and the branches should be full and full buds in the middle of the year. Using 2-3-year-old branches as scions, the survival rate of grafting is low, and the fuller the young tissue, the stronger the callus formation ability, which is beneficial to healing. In the growing season, it is best to use branches with sufficient nutrition and a certain maturity for scion grafting. Grafting of new shoots is best carried out after the vigorous growth of new shoots stops, and generally it is better to graft after 5-6 months. The survival rate of grafting from spring germination to vigorous growth of new shoots is low.
