How to Prune四季海棠 When It Grows Tall
Today's topic is about how to prune 四季海棠 when it grows tall and the pruning methods for begonia flowers, with detailed explanations on green plants and flowers, followed by a comprehensive introduction.
四季海棠 blooms beautifully and is favored by many gardening enthusiasts. Pruning is necessary for better growth of 四季海棠, so let's take a look at the pruning methods for when it grows tall.
1. Pruning Time
Pruning 四季海棠 can generally be done in spring and autumn. Summer is the growing season for 四季海棠, and the plants need leaves to synthesize nutrients. Pruning during this time will reduce the number of leaves, which is insufficient for nutrient synthesis. In winter, the plants are dormant, and pruning can lead to difficulty in recovery, making it unsuitable for pruning.
2. Pruning Methods
1. Retain the main stem, follow the survival of the fittest principle
When pruning, a 四季海棠 plant usually needs to keep 4 main stems. Too many stems will lead to dense foliage later on. The pruning should follow the survival of the fittest principle, keeping the healthy branches and cutting off the weak, diseased, injured, and slanted branches.
2. Keep the inner, remove the outer
When pruning, the inner branches of the plant can be pruned less, focusing mainly on the outer branches. This approach ensures good ventilation, reduces rotting of the leaves, provides ample growth space for the plant, and maintains an attractive shape.
3. Prune deformed branches
Branches that grow abnormally, such as curved branches, branches that cross through the plant, and branches that have stopped growing, should be pruned promptly.
4. Prune the branches on the main stem
When pruning branches that grow on the main stem, a few nodes should be retained, and the rest of the longer parts should be cut off. Since the plant flowers from the base of the branches, this pruning method ensures normal flowering and promotes reasonable growth of the plant.
3. Precautions
Do not prune when the plant is flowering. Because the flowering period requires more nutrients, pruning may lead to falling flowers, poor flowering, or even affect the next year's flowering. Pruning can be done before flowering, making sure it is far from the flowering period; or after flowering, which is pruning after the fruits or seeds are removed.
