Before planting magnolia seedlings, simply prune the roots and then cut off the weak branches of the seedlings. After planting, when the magnolia begins to grow, it is necessary to pick buds for 2-3 times to promote the growth of the lateral branches of the magnolia, and cut off the redundant branches and keep 5-6 strong branches. Before wintering, wintering pruning should be carried out.

1, seedling pruning

The bought magnolia saplings need pruning before planting. After transportation bumps, the roots and juices of seedlings will be damaged. Some old roots, dead branches, diseased branches and weak branches should be cut off, which can reduce the incidence of seedlings.

Step 2 plant and prune

Magnolia needs a big pruning after planting, so how to prune the planted magnolia? When the planting is completed and the magnolia begins to grow, some new buds should be removed first and repeated for 2 ~ 3 times, which will help the magnolia to send out side branches. After the lateral branches grow out, choose stronger branches, keep 5 ~ 6 branches, and cut off the rest.

3. Overwintering pruning

Magnolia grandiflora should be trimmed once before winter. The time in the north and the south may be different. Just wait until the temperature drops to 10℃. Cutting off the yellow leaves, removing the tender parts of the branches, and taking cold-proof measures after pruning can make Magnolia grandiflora overwinter more smoothly.

4. Precautions for pruning: Magnolia is generally pruned with twigs, and lignified branches are pruned as little as possible. After the lignified branches of Magnolia grandiflora, there is cotton wool in the center, which is easy to absorb water and infect after cutting. If pruning old branches, pay attention to keep the wound smooth and flat, and it is best to wrap the wound with plastic film.
