Magnolia grandiflora pruning techniques

Propagation seedling pruning

After the grafted Magnolia grandiflora seedlings survive, the rootstock buds should be removed in time, the trunk should be pruned upright, and the main trunk should be kept straight.

Seedling shaping

When Magnolia grandiflora grows too vigorously, a "double-headed phenomenon" will appear. If the main trunk grows too vigorously, the leaves near the top should be removed and the side branches should be shortened in time. In order to avoid the phenomenon of top-heavyness and upper branches easily falling over after rain, the plants should be pruned in time.

The mixed buds at the top of the Magnolia grandiflora usually consist of one main bud and two secondary buds. The branches grow relatively compactly, with many inner branches and overlapping branches. Pay attention to pruning them in time. During the growth process, pay attention to choosing a good branch height. Every year, according to the growth of the seedlings and the balance of the overall growth, the lowest branches should be pruned 1-2 times a year. The appropriate branch height should be about 1-1.2m.

Transplanting and pruning

Thinning branches and picking leaves are often used, and it is best not to prune. It is necessary to promptly remove diseased and insect-infested branches, overlapping branches, inner branches and branches that disrupt the tree shape, and keep the tree intact. Generally, 1/3-1/2 of the leaves can be removed. Removing too many leaves will reduce the transpiration pull and make it difficult for the roots to absorb water. In addition, the new branches of Magnolia grandiflora have weak germination ability, so it is best to bring a mud ball when transplanting and planting.
