Cause analysis of Lagerstroemia speciosa with few or no flowers.

The flowers in Wei Zi are beautiful and colorful. It is said that there is no Hundred Days Red in the flowers, but Wei Zi has the reputation of "Hundred Days Red" because the flowering period in Wei Zi can last from June to September. In many southern cities, Wei Zihua is planted on both sides of the road and is very beautiful in summer.

Osmanthus fragrans is a deciduous shrub or small tree that can grow to a height of about 7 meters. It likes fertile and moist soil, is also drought-resistant and has strong adaptability to soil. Widely cultivated in warm areas of the south.

Judging from the growth habits, Osmunda japonica is actually a relatively strong flower, which is extensively managed and resistant to tossing, and is often cultivated as a bonsai. So why do so well-cultivated plants reduce or not bloom? Then let's find out why.

Reasons of Lagerstroemia speciosa's lack of flowers and non-flowering.

Osmanthus fragrans is really easy to raise. If it doesn't die of drought, it basically won't be fed. The only difference lies in the number of flowers, or whether they can bloom. The reasons why Lagerstroemia indica does not bloom (less) are summarized as follows.

1, insufficient light

Lagerstroemia indica is a typical sunny flower, which needs sufficient light during its growing period. If the light is insufficient, it will grow white and bloom less or not.

For example, a large area has been in a rainy state for a long time this year, and so has Zhejiang. There are also fewer flowers and smaller bulbs on this side of the road. In fact, this is caused by insufficient light.

Last summer, the crape myrtle on both sides of the truth was very lively, with big bulbs, but this year it is very poor, and even some crape myrtle trees don't bloom at all.

If crape myrtle is planted in the ground, I suggest you plant it in the best light. If it is a potted plant, it should also be placed in a well-lit position. Of course, if there is no sun for such a long time as this year, it will be difficult.

If you say that your crape myrtle still rarely blooms or does not bloom, then you need to consider the following three aspects.

2. Frequent droughts

If the soil layer in the planting area is less, or the potted Lagerstroemia indica suffers from drought because of too extensive management, it will also cause Lagerstroemia indica not to bloom or rarely to bloom. Because frequent droughts will hinder the growth of Lagerstroemia indica buds, the buds will disappear because of drought before they grow well.

Although the management of Osmunda japonica is extensive, it should be given enough fertilizer and water. If you don't eat or drink, you have to work. No one can stand it!

3. Serious lack of fertilizer

If it is potted Lagerstroemia indica, topdressing is also necessary on the premise of ensuring water content. We don't need extra topdressing for Lagerstroemia indica planted on the ground, but potted Lagerstroemia indica will grow thin and unable to bloom because of lack of fertilizer if it is not topdressing.

After all, there is limited room for growth and limited access to nutrients. If you don't want to use water-soluble fertilizer, you should at least put enough base fertilizer in the pot, and at least ensure that fermented organic fertilizer is applied once a month during the growing period, so that the management is relatively extensive and the nutrients needed for the growth and flowering of Lagerstroemia indica can be ensured.

If it is potted Lagerstroemia indica, we should pay attention to controlling the amount of nitrogen fertilizer, pruning frequently in the bud stage of branches, increasing the amount of phosphorus and potassium fertilizer to achieve the effect of full flowering of trees, and do not let a branch grow to one or two meters and bear a big flower ball.

4. Lack of pruning

If your Osmunda japonica is full of sunlight and water, but only has few flowers and small bulbs, then you need to consider pruning.

Osmanthus fragrans is resistant to pruning. Usually, after the leaves fall in winter, we will cut the branches of Lagerstroemia indica bare, that is, to the height required by the main stem. After pruning, they will be completely wooden stakes, so that new buds will sprout at the top of the stakes in spring. These new buds thrive and often produce very large bulbs.

If Lagerstroemia indica is not pruned in winter, or lightly pruned, the old branches of Lagerstroemia indica will send out many new buds in spring, so the nutrients are scattered, the new branches will grow thinner and shorter, and the natural flower balls will become smaller, but the number of flower balls will increase, which is also beautiful in general, but the flowering effect is different.
