How to prune the iron begonia and what are the pruning times and methods

Pruning time of Begonia thornii

The iron hollyhock can be pruned once a year, and the time for pruning must be chosen carefully. Spring and autumn are more suitable seasons. The temperature in spring is suitable and the growth rate is fast. After pruning, the plants will sprout quickly and will not affect the growth of the plants.

In autumn, the growth rate of the iron balsam pear slows down and the nutrients it needs decrease. Pruning will have less impact at this time. Although it can be pruned in summer and winter, it is not the best time for pruning. It is difficult to form nutrients in summer, which affects the recovery of the plant. The temperature is low in winter, and although it does little harm to the plant, pruning and regeneration are more difficult at this time.

How to prune the thorn begonia

1. Topping

The iron begonia flower must be topped in time during the maintenance period, otherwise it will grow too tall, the nutrients will not be concentrated, and it will not bloom better. Topping is generally done when the plant grows to a certain height, just cut off the middle part. In this way, the nutrients are concentrated, the side branches can be better sprouted, and the number of flowers will increase in the later period.

2. Pruning

When the side branches of the iron balsam pear grow too high, the branches can be pruned short. When there are withered or dry branches on the plant, such branches should be cut off. If there are some diseased and insect-infested branches and leaves, they should not only be pruned cleanly, but also disinfected and sterilized to avoid infection of the pruned incisions.

3. Notes

It is best to use special tools when pruning the iron balsam pear. The cut should be kept flat to minimize damage to the plant. After each pruning, move it to a well-ventilated and cool place. Do not water it to avoid rotting of the wound. Wait until it resumes growth before maintaining it normally.
