Lagerstroemia indica does not germinate. What should I spray?

Lagerstroemia indica is a deciduous tree species, which began to shed leaves in the middle of 5438+ 10 under natural conditions. In order to prolong the leaf viewing period after flowering, the old leaves can be picked in early September. Note that the leaves on the branches should not be picked at once, but in batches.

After picking leaves, water should be sprayed on the branches and the remaining leaves frequently. New leaves will appear in 15 ~ 20 days, which are small, red, thick and shiny. All the branches that are not lignified are purplish red, which can be enjoyed in 12 months, and will not affect the flowering and leaf emergence in the following year.

Step 2 apply fertilizer

Based on the principle of thin application and diligent application, nitrogen, phosphorus and potassium fertilizer are applied together in early March to promote bamboo shoots, phosphorus and potassium fertilizer are applied once from late May to early June to promote flower bud growth, and flowering fertilizer is applied once from late July to early September to make flowers bloom more brightly.

3, plastic pruning: Osmunda japonica has thick branches and a large amount of new buds, which is very resistant to pruning. After flowering, the residual flowers should be cut off, which can prolong the flowering period. At the same time, some cross branches, diseased branches and radiation branches should be cut off in time to avoid consuming excess nutrients.
