Osmanthus fragrans can be pruned three times, mainly from March to April in spring,10-165438+10 in autumn and 1-2 in winter. Pruning in early spring: before the osmanthus tree germinates in early spring, it can be pruned once, mainly to cut off the weak branches, and then cut off the top 3-5cm of its main branches together with the new buds, which can promote it to grow more new branches and make it grow more densely. Pruning in winter: Osmanthus fragrans will enter a dormant period in winter, and its growth is slow. Pruning is not easy to damage branches, so it can be pruned again. You can cut off the branches that are not growing well, cut off the branches that are too long and cut off the branches that are too dense, which is more conducive to its growth in the coming year.

Pruning method of osmanthus trees

When pruning young osmanthus trees, only the trunk 50-60cm and 3-5 lateral branches are kept, and the rest are all cut off. Pruning young trees can not only ensure nutrition, but also be the basis for developing beautiful plant types of osmanthus trees. 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. The trunk grows faster than the lateral branches, so when pruning, you should cut the trunk again, lightly or not. In addition, the diseased branches, over-dense branches, over-flourishing branches and inner branches should be cut off together to make the osmanthus trees lush and beautiful. Mature osmanthus trees do not need to be pruned in a big way, but only need proper shaping and pruning to maintain a beautiful tree shape. Osmanthus fragrans has 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, usually 10 days before germination in early spring. Before pruning, a fertilizer mixed with less than 5% urea and potassium dihydrogen phosphate should be applied. When pruning, 2-3-year-old branches and over-dense branches should be cut off, and the cut mouth should be smooth.

Matters needing attention in pruning osmanthus trees

After pruning, osmanthus trees need to provide some water and nutrients, because osmanthus trees need new buds and consume a lot of nutrients. If the nutrients are insufficient, the buds will become weaker and thinner, deformed leaves will appear, and so on. Fertilizer, choose multiple fertilizers.
