1. Growth habit

Forsythia suspensa flower is a temperate tree species, which is resistant to cold, drought and semi-shade, and has low requirements on soil. Forsythia suspensa flower is afraid of waterlogging, so it is required to be planted in a sheltered and well-drained place.

2. How to prune the forsythia suspensa flower

The forsythia suspensa flower can be pruned into various shapes, such as a happy shape and a bush shape. Here are two pruning methods:

1. Happy shape: After the forsythia suspensa flower is planted, when the forsythia suspensa flower is about 1 meter high, the top of the trunk is cut off at 7-8 cm from the ground, so that it can be plucked in summer to promote branches in different directions to grow.

2. Shrub shape: cutting propagation is based on the strong germination of forsythia suspensa flowers. In the early spring of the second year of planting, the top of the plant is cut off 2-25 cm from the ground. When the temperature rises in spring, the roots of forsythia suspensa flowers begin to move, and the nutrients stored in the roots will be transported upward. Under the condition of increasing fertilizer and water management, the branches of forsythia suspensa flowers grow rapidly. When they grow to about 25 cm, the terminal buds are removed, so that secondary branches occur. More than 1 secondary branches can germinate on each primary branch. After ear picking, it is to collect the third-grade branches or fourth-grade branches sprouting on the second-grade stubble.

Second, the propagation method

Forsythia suspensa flowers are mainly propagated by cutting. The hard branches are planted in March, and the tender branches are planted in the rainy season in June. The cutting length is about 12 cm, and the survival rate can reach more than 9%. It can be transplanted after defoliation in winter that year. After planting Forsythia suspensa flowers, the old branches are cut off 1 cm above the ground every year to promote them to form clusters, and the sprouted new branches are more dense than the old branches.

Flower of Forsythia suspensa, which is nicknamed Golden Stripe, is a deciduous shrub with erect stems, spreading or drooping branches, brown branchlets, simple leaves or small leaves, yellow flowers, and 1-3 axillary flowers. Forsythia suspensa blooms first and then leaves open in early spring, which is an excellent ornamental tree species in early spring. It is suitable for planting in gardens and roadsides, and its varieties are: Forsythia suspensa, Forsythia simplex and Forsythia trifolia.
