Pruning treatment: all the dead and diseased branches of Lagerstroemia indica are cut off. 4. Propagation method: Lagerstroemia indica keeps warm before winter.

How to judge the death of Lagerstroemia indica 1 and observe its growth state?

If we want to judge whether Lagerstroemia indica dies, we need to observe the growth state of the plant. If you find that the leaves of Lagerstroemia indica are dry and yellow, no new leaves will grow, which means that Lagerstroemia indica is dead. If the leaves of Lagerstroemia indica grow buds after falling, it means that it is still alive.

Step 2 observe the trunk

To judge whether Lagerstroemia indica is dead, you can prepare a sharp sterilized knife and cut a wound on the trunk or root of the plant. If the wound is green or white and does not rot and turn black, Ziwei is not dead. It should be noted that this method may hurt Lagerstroemia indica.

3. Pruning treatment

When pruning Lagerstroemia indica, it is necessary to cut off the weak branches, dead branches and diseased branches with poor growth, so as to prevent the loss of redundant nutrients and promote the growth of new branches, and then spray diluted potassium permanganate solution on the fracture of Lagerstroemia indica to maintain the normal growth of the plant.

4. Breeding management

When cultivating Lagerstroemia indica, fertilization should be applied 1-2 times a month in the peak season of plant growth to promote flower bud differentiation, and heat preservation measures should be taken for Lagerstroemia indica before winter. Straw ropes or mats can be wrapped around the trunk of plants to avoid frostbite.
