What are the factors that affect the flowering of Osmunda japonica?

Reason one: no pruning during the growing period. If the branches are not pruned properly during the growth period, it will not only affect the appearance of the plant, but also consume a lot of nutrients, which is not conducive to the germination of flower buds, thus affecting the normal flowering and causing less flowers.

Reason 2: Too high room temperature in winter affects the normal dormancy of plants, so that physiological functions are still vigorous and nutrients are consumed, which leads to premature germination and leaf pumping, and plants are weak in normal growth period, and rarely bloom or not bloom in the second year.

Reason 3: Soil with high salinity is the most suitable soil for Lagerstroemia indica growth, while planting in soil with salinity exceeding 0. 1% and ph exceeding pH 7.5 will affect the normal growth and flowering of plants.

Reason 4: Inappropriate light temperature: Lagerstroemia indica is mainly produced in a high-temperature climate, so attention should be paid to maintaining a temperature suitable for the normal growth of the plant during maintenance, otherwise it will affect its normal physiological functions, such as transpiration and photosynthesis, and then affect the production and storage of required nutrients, resulting in insufficient nutrient supply and difficulty in flowering.

Reason 5: Infected by pests and diseases, the infection of various pests and diseases will seriously affect the accumulation and normal growth of plant nutrients, and it is easy to cause the phenomenon of falling flowers and buds.

In addition to reasonable maintenance and management to increase the resistance of plants to pests and diseases, it is also necessary to spray chemicals in a timely and appropriate amount to effectively control pests and diseases.

Reason 6: Excessive or insufficient water and fertilizer is in the growth period of Lagerstroemia indica. If excessive water and fertilizer are used, the branches and leaves are easy to grow white, and most of the nutrients originally supplied to flower buds and buds are consumed by organs such as roots and leaves, resulting in insufficient nutrients needed for flower buds to bloom, resulting in less flowers or no flowers.

In addition, when the buds are pregnant, the fertilizer concentration is too high, and the watering amount is not controlled properly, so that the redundant fertilizer in the soil can not be diluted, and the flowers and buds are easy to fall off after burning the roots. In the growth period of flowers, insufficient water and fertilizer supply will inhibit the normal growth of plants, and it is easy to spend less or not to bloom.
