Hydrangea is a very beautiful flower, it is in the peak season of spring and summer, but after the onset of autumn, its growth rate gradually slows down. In order to keep hydrangeas beautiful and healthy, proper pruning is required. Let's take a look at how to prune hydrangeas after the beginning of autumn.
First of all, we need to understand the growth characteristics and Xi of hydrangeas. Hydrangea is a shrub or small tree that grows relatively fast and prefers to grow in sunny, well-drained, fertile soil. In spring and summer, it needs plenty of sunlight and moisture to promote its growth and flowering. However, after the onset of autumn, the growth rate of hydrangeas will gradually slow down, and this is when it needs to be pruned properly.
The purpose of pruning is mainly to promote the healthy growth and flowering of hydrangeas, as well as to control their height and morphology. After the beginning of autumn, we need to prune the branches of the hydrangea so that they can better withstand the cold and stay healthy in winter. Specifically, we can do the following:
1.Pruning branches: After the beginning of autumn, hydrangea shoots can be pruned to remove some weak, wilted, or diseased branches. When pruning, you need to be careful not to overprune so as not to affect the growth and flowering of hydrangeas.
2.Pruning residual flowers: If the hydrangea has already bloomed, then pruning the residual flowers can be carried out after flowering to keep the plant neat and beautiful.
3.Control the height: If the height of the hydrangea has already exceeded expectations, proper pruning can be done to control its height and morphology. The top shoots can be removed when pruning to promote the growth and flowering of the side branches.
4.Promote flowering: If you want hydrangeas to be able to bloom in winter as well, proper pruning can be done to promote their flowering. Specifically, the branches of hydrangeas can be shortened or re-pruned after the beginning of autumn to promote their branching and flowering.
It should be noted that there are a few things to keep in mind when doing pruning:
1.Pruning time: It is best to prune when the weather is clear and avoid pruning in rainy or wet weather to avoid wound infections and pests and diseases.
2.Pruning tools: Sharp scissors or blades are required to prune to avoid damage or scarring of the plant.
3.Wound treatment: After pruning, the wound needs to be treated, which can be disinfected and protected with plant ash or fungicide.
4.Fertilization: Proper fertilization is required after pruning to promote the growth and flowering of the plant. Some organic fertilizers or compound fertilizers can be applied.
In conclusion, pruning hydrangeas after the beginning of autumn is very important to help the plants stay healthy and beautiful. You need to pay attention to the above points when pruning to ensure the effect and quality of pruning.
