When does Lagerstroemia indica flower bud differentiate?

Wei Zi: Flowers are purplish red.

(2) Cuiwei: blue-purple flowers and dark green leaves.

(3) Red tail: fireworks red.

(4) Yin Wei: The flowers are white or slightly cocoon-colored, and the leaves are light green.

Cuiwei, with the best blue petals, is a panicle with the top of a new branch, which is 20 cm long. Each flower has 6 petals, which is wrinkled like a roulette wheel. The tree is full of flowers, gorgeous as a sunset, so it is also called full house. The result is a capsule, which looks like soybean and contains many seeds. It expires on 1 1 month.

The Yangtze river basin began to sprout in April, with strong germination. The formation of flower buds is about the beginning of June after the branches stop growing; At this time, the temperature is above 30℃ and there is little rain, which is beneficial to flower bud differentiation. Flowering inflorescences are usually around June 20, and only a few days need to be taken out, and the basal buds will begin to bloom. If the temperature is lower than 30℃ and there is more rain in June, the top will continue to extend, the inflorescence will be pulled out, or a few branches will bloom. Allow yourself to grow, dense and slender, easy to aging, few or no inflorescences, or flowering every other year. The single flowering period is 5-8 days, each inflorescence can bloom for about 50 days, and the flowering period of the whole plant group is longer than 120 days. Generally, young trees bloom 7- 10 days earlier than old trees. If it is rainy in summer and the temperature is below 30℃, the flowering of old trees will be delayed, only a few flowers will bloom, but young trees will not. However, the newly transplanted Lagerstroemia indica was injured in the root and had poor water absorption ability, but it blossomed on time. Long-term shading cannot be tolerated, otherwise it will rarely bloom and grow poorly. The flower branches are 30-50 cm long, grow healthily, have long inflorescences, and more flowers are preferred; Slender branches and long branches, short inflorescences and few flowers.
