Paulownia is a fast-growing tree species, and timely pruning can promote plant growth and control a reasonable and beautiful tree shape. Let's take a look at the pruning method of paulownia.

Pruning method of paulownia

Softwood cutting and bud smearing

Straight paulownia seedlings can be cultivated by twig cutting and bud smearing. Generally, the curved tips are cut off at the full buds, and 4-5 buds below the buds are cut off. The cut bud can form a new main shoot, and it should be noted that the cut bud is full and strong, and the bud tip is upward.

Sparse branches

Prune dense branches, cross branches, weak branches and branches with pests and diseases, lightly prune weak branches and re-prune strong branches. Smooth incision. Thinning branches can weaken the overall growth, but can enhance the growth of other branches, especially the growth of lower branches; At the same time, it is beneficial to ventilation and light transmission, which can promote the growth of trunk and blossom early.

short cut

Short cutting is to cut off some branches, which can stimulate the germination of lateral buds under the incision and extract new buds, increase the number of branches and facilitate more flowering. In a certain range, the heavier the short cut, the more vigorous the new bud germination.

take back

Retraction is to cut off branches that have been more than 2 years old. Keeping a section of old branches or trunk base and cutting the rest can promote the vigorous growth of some cut branches, and also stimulate dormant buds to sprout long branches, which is beneficial to cultivating COVID-19.

Flat stubble

It is mostly used to cultivate the rejuvenation and regeneration of excellent trunk. By removing all the aboveground branches near the ground, the germination and regeneration near the root neck of plants can be stimulated, and the trunk shape can be completely transformed.
