How to prune jasmine

Pruning methods

Pruning of forsythia can regulate the tree's vigor, save nutrients, make the branches evenly distributed, and make the plant shape beautiful. Most importantly, it is conducive to flowering. The timing and method of pruning forsythia is a key part of growing forsythia well.

Prune the branches within 10 days of the flowers withering, leaving 2 to 3 flower buds on each branch.

Apply nitrogen fertilizer twice after pruning, once every 10 days, to promote the growth of new branches. When the new branches grow to 15 cm, apply phosphorus fertilizer again 3 times, once every 7 days. It can promote the formation of flower buds and the development of buds and flowering.

Note: The flower buds of forsythia are formed on the branches of the first year, so it is not suitable to be pruned in autumn and winter. Pruning in autumn and winter will cut off the flower buds formed in summer, resulting in no flowering.

Pruning techniques

The pruning of forsythia is mainly divided into shaping and root pruning. Here are some specific pruning tips:

When planting, there should be sufficient basal fertilizer in the basin, and plenty of water and fertilizer should be used to grow the plants until mid-July, when pruning is just in time. Control watering after pruning and water when you see the leaves curling. Apply phosphorus fertilizer twice more in September and carry out normal maintenance in October. Ensure sufficient sunlight in November, and prune again after flower buds appear in January. When flowering, the branches should be about 10 cm and full of flowers.

Usually it is pruned twice, once in spring after flowering and once again after a period of growth. To ensure beautiful shape, pruning can be carried out in late March and early April. After side buds grow out, some of the side buds can be removed according to the growth of the branches.

If the plant is not pruned or cut short for a long time, the branches and leaves will become sparse and the flowering will gradually decrease, affecting its appearance.
