Pruning time of osmanthus trees
Osmanthus fragrans can be pruned for three times, mainly in March-April in spring,10-165438+10 in autumn and 1-2 in winter.
Pruning in early spring: before the osmanthus tree shoots in early spring, it can be pruned once, mainly to cut off the dry and weak branches, and then cut off the top of its main branch 3-5 cm together with the new buds, which can promote it to grow more new branches and make it grow more densely.
Pruning in winter: osmanthus trees will go into dormancy in winter, grow slowly and are not easy to be injured by pruning. Therefore, it can be trimmed again. First, it can cut off its own branches that are not growing well, cut off too long branches and prune too dense branches, which is more conducive to its growth in the coming year.
Pruning method of osmanthus trees
When pruning young osmanthus trees, it is good to keep the trunk 50-60 cm and 3-5 lateral branches, and all the rest should be cut off. Pruning young osmanthus trees can not only ensure nutrition, but also form the basis of beautiful plant shape. Proper pruning can make osmanthus trees blossom ahead of time, which has a good ornamental effect in the early stage.
The top advantage of osmanthus trees 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, we should also cut off the weak branches, over-dense branches, long branches and inner branches together, so that the osmanthus trees will flourish and look beautiful. Mature osmanthus trees do not need to be pruned greatly, but only need proper pruning to maintain a beautiful tree shape.
Osmanthus fragrans has a strong germination ability, and the old piles should be trimmed, and the pruning method is similar to that of adult trees. In addition, old piles need pruning every 2-3 years, usually 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.
Matters needing attention in pruning osmanthus trees
After pruning, osmanthus trees need to provide some water and nutrients, because osmanthus trees need to grow new buds, which consume a lot of nutrients. If the nutrients are insufficient, the bud will be weak and thin, and it will have deformed leaves, so choose multi-element fertilizer.
