The ornamental value of crape myrtle mainly comes from the blooming flowers. If it does not show its normal posture during the flowering period, it means that there are more or less problems in the maintenance process. What are the specific problems? Let’s find out together.

Reason 1: No shaping and pruning during the growth period.

Reason 1: No pruning during the growth period.

If the branches are not properly pruned during the growth period, it will not only affect the shape of the plant It is not only beautiful, but also consumes a lot of nutrients, which is detrimental to the germination of flower buds, thus affecting normal flowering and resulting in less flowering.

Reason 2: The room temperature is too high in winter

Excessively high room temperature affects the normal dormancy of plants, causing physiological functions to still be vigorous and consuming nutrients, leading to premature germination and leaf withdrawal. In the next year, there will be few or no flowers due to the weakness of the plants in the normal growth period. .

< h2> Reason 3: The soil contains high saline-alkali content

The most suitable soil for the growth of crape myrtle is slightly acidic and neutral soil. When the saline-alkali content exceeds 0.1%, the pH exceeds Planting in soil with ph value 7.5 will affect the normal growth and flowering of plants.

Reason 4: The light temperature is not suitable

The origin of crape myrtle is dominated by high-temperature climates. Therefore, care must be taken during maintenance to maintain a temperature suitable for the normal growth of the plant. Otherwise, its normal physiological functions, such as transpiration and photosynthesis, will be affected. It affects the production and storage of required nutrients, resulting in insufficient nutrient supply during the flowering period and difficulty in flowering.

Reason 5: Attacked by pests and diseases

Infection by various diseases and insect pests will seriously affect the accumulation of nutrients and the normal growth of plants, and can easily cause flower and bud drop.

In addition to increasing the resistance of the plant itself to diseases and insect pests through reasonable maintenance and management, pesticides should also be sprayed in a timely and appropriate amount to effectively prevent and control pests and diseases.

Reason 6: Excessive or insufficient water and fertilizer

If excessive water and fertilizer are applied during the growth period of crape myrtle, it is easy to cause the branches and leaves to become elongated. Most of the nutrients originally supplied to the flower buds and buds are consumed by the roots, stems, leaves and other organs, resulting in the flower buds needing Lack of nutrients causes little or no flowering.

In addition, too high a concentration of fertilizer was applied during the budding period, and the amount of watering was not properly controlled, so that the excess fertilizer in the soil could not be diluted, which would easily cause the flowers to fall after root burn. buds; insufficient water and fertilizer supply during the flower growth period will inhibit the normal growth of the plants, and it is also easy to have few or no flowers.
