Lagerstroemia speciosa has lush leaves and does not bloom.

Wisteria, not flowering; It should belong to the seedling growth period, or the flowering period has not yet arrived. It takes at least 8 ~ 10 years for wisteria to blossom. It is required that the planting ground has deep soil layer and good drainage performance, and the flowering period is from mid-April to early May.

Wisteria, also known as wisteria. It belongs to Leguminosae and Wisteria, and it is a climbing and winding deciduous vine. It is distributed in most areas of China. Before planting wisteria, scaffolding should be set up, and thick branches should be tied to the scaffolding to climb along it. Because wisteria has a long life and thick leaves, the scaffold material must be strong and durable. Or trim and control the height, and cultivate a tree shape to facilitate its normal growth.

Generally, when young trees are first planted, the branches can't form flower buds, and adult seedlings will bear peanut bud. If it doesn't bloom for several years, it's because the tree is too strong, with too many branches and leaves, and the tree is weak, so it is difficult to accumulate nutrients. The former uses partial root cutting and sparse branches and leaves, while the latter can blossom by adding fertilizer. Fertilizer should be properly applied with more potassium fertilizer. Topdressing is usually 2~3 times during the growth period. After flowering, 5~6 buds can be cut off from the middle branches and weak branches to promote the formation of flower buds.
