Osmanthus fragrans can be twisted and pulled in the primary stage without pruning the whole plant. Later, when it grows vigorously, it is necessary to pull it out, remove the branches with 3-4 leaves at the top of the plant, and cut off the weak branches and diseased branches, so as to avoid the waste of nutrients and the spread of diseases. The trimmed wound needs disinfection, and carbendazim solution can be sprayed for prevention and treatment.

When will osmanthus be pruned?

Osmanthus fragrans should be pruned in June, 5438+ 10 or February every year, and can be pruned slightly all year round.

The optimum cutting length of osmanthus fragrans is 8- 12 cm, and the depth of cutting is about 2/5 of the cutting length. Then compact the soil, water it 1 time, put it in a ventilated and cool environment, and spray it with a sprayer, 1-2 times a day. Generally, after 3-4 months, the seedlings can grow new roots.

Prune the branches and leaves of osmanthus fragrans

First, don't prune the whole plant.

Osmanthus fragrans can't be pruned in the primary stage, mainly by twisting and pulling branches. Twisted shoots artificially change the growth direction of young branches in the early stage, which plays a role in adjusting the position and improving the ornamental value. Pulling branches mainly relies on iron wire to nail stakes on the ground to control the growth direction of thick branches.

Second, small pruning.

First, we should pick the branches with 3-4 leaves at the top of the plant, then cut them short. Keeping more than half of the branches can promote the growth of buds on the upper branches, and finally take them back. This is mainly done for long biennial branches. We should cut off some branches that grew last year and replace the branches.

Third, trim sharply.

If it is pruned greatly, it may completely change the original tree shape, which can be used in conjunction with grafting, and the effect is better.

Pruning skills of osmanthus fragrans

During the growth of osmanthus fragrans, it is necessary to prune the aged, yellow and black leaves. In order to make the shape more beautiful, you can trim off the branches that are too long, too dense and unsightly.

If it is poor growth or disease, it is necessary to cut off weak branches and diseased branches at this time to avoid wasting nutrients and spreading diseases.

Pruning and flowering of osmanthus fragrans

Prune the dense branches of osmanthus fragrans in time to increase the light transmittance of the whole plant. Only one branch can be left in the same direction, so that it can grow from the opposite or oblique position, which will promote the differentiation of flower buds and make osmanthus blossom more easily.

Notes on Pruning Osmanthus fragrans

When pruning osmanthus trees, tools need to be disinfected in advance, and the cut after pruning needs to be disinfected to avoid the infection of germs, and carbendazim solution can be sprayed for prevention and control.
