Grafting time and method of Lagerstroemia indica

The grafting of Lagerstroemia indica is best in the middle of March-April, when its tree buds just sprout, or in August-June of that year. At this time, Lagerstroemia indica is in the growth period, and the grafting survival rate is high.

Lagerstroemia indica grafting method

Bud grafting: When Lagerstroemia indica bud grafting, cut a knife vertically from top to bottom on the rootstock, then cut a knife at a lower angle of 30 degrees, select the newly germinated bud from the scion, cut it down into a shield shape, stick it on the cambium, bind it from bottom to top, and wait for germination.

Split: Lagerstroemia indica split in early February-March, select stout seedlings, cut them vertically from the peripheral tree core, then take scions with 2-3 buds, cut them into wedges, put them outside, insert them into the split of rootstock, and then wrap them with plastic film.

Matters needing attention in grafting Lagerstroemia indica

Fixation: Lagerstroemia indica will fix the grafted rootstock on the branches of Lagerstroemia indica without shifting. It can graft multiple rootstock seedlings on each branch, which can improve the grafting survival rate. You can use healing agents or wooden sticks to fix the joints, wrap them tightly, and fix the residual limbs to prevent shaking.

Maintenance: In the early stage of maintenance after grafting, it is best to spray water on the branches three times a day to reduce water evaporation, keep the substrate moist and breathable, shade in time when the temperature rises in summer, and increase watering. Fertilization is not suitable for curing period.
