Osmanthus fragrans blooms all year round, with strong fragrance, with strong fragrance in summer and autumn and slight fragrance in spring and summer.

Pruning time of osmanthus in four seasons
Pruning in early spring: osmanthus fragrans can be pruned once in March-April when it grows new branches and buds in early spring. Withered and weak branches and leaves can be pruned, and then the top of its main branch is pruned 3-5cm together with new buds. It should be planted after it blooms in10-165438+10.
Pruning in winter: Osmanthus fragrans grows very slowly in winter, so it is not easy to get hurt by pruning. In winter, during1-February, you can cut off the branches that are too prosperous and dense, and shorten the branches that are too long, which is more conducive to its growth in the coming year.
Pruning method of osmanthus fragrans in four seasons
When pruning young osmanthus fragrans, just keep the trunk and 3-5 lateral branches of 50-60cm, and cut off all the rest. Pruning young osmanthus fragrans can not only ensure nutrition, but also form the basis of beautiful plant shape. Proper pruning can make Osmanthus fragrans blossom ahead of time, which has good ornamental effect in the early stage.
The top advantage of osmanthus fragrans is very obvious, and the trunk grows faster than the lateral branches. Therefore, when pruning, it is necessary to re-cut the trunk, lightly cut or not cut the side branches. In addition, it is necessary to cut off the weak branches, over-dense branches, long branches and inner branches together, so as to make the sweet-scented osmanthus flourish and beautiful, and it is not necessary to prune the mature sweet-scented osmanthus, just keep the tree shape beautiful.
Osmanthus fragrans has a strong germination ability, so old piles should be trimmed, and the pruning method is similar to that of adult trees. In addition, old piles need to be pruned every 2-3 years, and pruning is generally carried out 65,438+00 days before germination in early spring. Before pruning, the mixed fertilizer of urea and potassium dihydrogen phosphate below 5% should be applied. When pruning, 2-3-year-old branches and over-dense branches should be cut off, and the cut must be smooth.
Notes on Pruning Osmanthus fragrans in Four Seasons
Osmanthus fragrans should be watered and fertilized in time after pruning, because Osmanthus fragrans needs to grow new buds, which consume a lot of nutrition. If the nutrients are insufficient, the bud will be weak and thin, and it will have deformed leaves, so choose multi-element fertilizer.
