Does Wisteria Drop Leaves in Winter?
For most women, the planting details of rose Wisteria, the question of whether Wisteria drops leaves in winter, are as follows:
It's already deep autumn and winter is not far off. Some flower friends have asked whether Wisteria drops leaves in winter. Wisteria is a deciduous plant, which means that when the temperature drops, Wisteria will drop leaves, which is the same as other shrub roses. In southern regions, such as Hainan, Wisteria may not drop leaves, but this is not a good sign because roses need to hibernate in winter to bloom well the following year. Therefore, it is difficult to grow roses in Hainan, and many roses do not bloom easily or bloom less.
The main difference in management between Wisteria and shrub roses is pruning. Shrub roses may be pruned heavily at times, while Wisteria does not require this. Generally, Wisteria has the habit of flowering on new branches. Therefore, it is necessary to break the apical dominance; otherwise, only a few buds at the top of the branches will germinate, resulting in a sparse display of flowers, which does not show the grandeur of the climber. For winter pruning of Wisteria, cut off about 10 to 20 centimeters from the top of the main branches, retain three or so buds on the flowering lateral branches, remove the very thin and short basal branches, and spread the branches near the wall or fence in a peacock fan-like manner, allowing the branches to be as倾斜 or horizontal as possible;
Let the flowers wrap around the stake, tying and wrapping as you go; for branches exceeding the range of the stake, just cut them off;
For arches, tie the branches along the shape of the arch, or wrap them around, or let the thicker branches follow the shape of the arch while the thinner ones wrap around. Similarly, for branches that exceed the range of the arch, just cut them off. First pull the longer branches horizontally, then use shorter branches to fill in the more sparse areas. For large flower varieties, the branches can be spaced about the width of a palm, and for medium flower varieties, the distance of a fist is enough.
Fertilization
1. Fertilize after the flowers have faded, which is called "gift fertilizer" in Japan, meaning to thank the flowers and help them recover growth.
2. During the bud formation stage, you can apply flowering fertilizer to help the buds grow.
3. Base fertilizer: every winter when changing pots, make sure to provide enough, such as black chicken fertilizer, bone meal, plant ash, and slow-release fertilizer, depending on what you have.
4. Roses like plenty of water and fertilizer, and this has always been true. They cannot tolerate drought, or they may get red spider mites. If roses are wilted in the sun for several consecutive days, make sure to water them thoroughly and spray the back of the leaves to prevent red spider mites. If you want lush growth, you need to fertilize, but the result of lush growth is an increase in the amount of water needed.
5. Do not fertilize during the flowering period, which is a relative term. The flowering period of roses refers to the stage of mass flowering, with dozens or even hundreds of flower buds at once. This is the condition that professional flower friends achieve through frequent pruning. If no pruning is done and the roses bloom continuously with a few scattered flowers, this is not a strict flowering period, and fertilizing will not have much impact.
