How to prune a Hawaiian hibiscus
A Hawaiian hibiscus is best pruned in spring and autumn. Usually, when the plant has reached a certain height, it is topped by cutting off the central part, allowing nutrients to be concentrated and better initiating side branches. When the side branches grow too tall, the stems can be shortened. If there are withered or dry branches, they should be cut off, and branches with diseases and pests should be pruned promptly to reduce bacterial transmission.
Timing for pruning a Hawaiian hibiscus
A Hawaiian hibiscus can be pruned once a year, and the timing of pruning must be chosen well. Spring and autumn are more suitable. The temperature in spring is suitable, and the growth rate is fast. Pruning can quickly initiate new growth without affecting the plant's growth.
In autumn, the growth rate of a Hawaiian hibiscus slows down, and the required nutrients decrease, making pruning at this time have less impact. Although pruning can be done in summer and winter, these are not the best times. In summer, it is difficult to form nutrients, affecting the plant's recovery. In winter, the temperature is low, and although the damage to the plant is small, pruning at this time makes regeneration more difficult.
Methods for pruning a Hawaiian hibiscus
1. Topping
During the maintenance period, a Hawaiian hibiscus should be topped in time; otherwise, it will grow excessively, nutrients will not be concentrated, and it will not bloom well. Topping is usually done when the plant has reached a certain height, by cutting off the central part to allow nutrients to be concentrated and better initiate side branches, which will also increase the number of flowers in the later stage.
2. Pruning
When the side branches of a Hawaiian hibiscus grow too tall, the stems can be shortened. When there are withered or dry branches on the plant, such branches should be cut off. If there are branches with diseases and pests, not only should they be pruned cleanly, but also disinfected and sterilized to prevent the pruning cuts from becoming infected.
3. Precautions
When pruning a Hawaiian hibiscus, it is best to use special tools, and the cut should be kept flat to minimize damage to the plant. After each pruning, move the plant to a well-ventilated, shady place, do not water it to avoid rotting of the wound, and only resume normal care after it has recovered from growth.
