When is the best grafting time for fruit trees?

The best grafting time of fruit trees is spring.

Grafting season: In fact, plants can be grafted all year round, but grafting in spring and autumn is the most common, followed by grafting in summer, and grafting in spring is the best season for most trees. In winter, trees are dormant, sap stops flowing, and bleeding is the lightest, but it is not easy to produce callus, scions and rootstocks are difficult to heal, and scions are easy to starve to death.

Grafting in summer is mostly twig-to-twig, twig-to-hardwood grafting. In summer, the temperature is high, the evaporation is large, the management after grafting is difficult, and the scion is easy to die. Grafting in autumn is not easy to lignify. Generally speaking, spring is most suitable for tree grafting. Moreover, the temperature, humidity and light in spring are the most suitable seasons for healing tissue growth.

Extended data:

Key points 1: Strata should be aligned.

All dicotyledonous plants have cambium between bark and wood (bark is wood, that is, cambium is the top layer of the tree), and cambium is also the growing point of plants, growing inward and outward.

When grafting, the cambium must be aligned, that is, the line at the junction of bark and wood of mother wood and scion should be well butted, otherwise the scion is not easy to survive.

Point 2: The wedding interface should be wrapped tightly.

Grafting is very important, there is no link, even if you do the previous link well, one link is not done well, which will greatly reduce the survival rate.

Here is a formula: do it (autumn buds, spring and summer buds). If the dressing is not tight, the scion will be dehydrated and lose its vitality before survival, and in severe cases it will die. When binding, use plastic straps and seal them.

Point 3: Don't graft with sprouted scions.

Grafting should be carried out before the temperature warms up and the grafted buds are full but not germinated, and the survival rate of grafting with sprouting branches will be reduced.
