How to grow weigela? Detailed guide to cultivation methods and precautions
Weigela is a shrub plant in the honeysuckle family (Caprifoliaceae). It is fairly widely distributed in North China and is a highly ornamental flower. It is used in various gardens and is very popular with many people. It can also be grown as a potted plant at home, and its economic value is also considerable. So how should weigela be grown? And what precautions are there? Let's take a look together below at the cultivation methods and precautions for weigela!
1. Soil selection
Before growing weigela, we must first choose the right soil for growing it. Although weigela is not very strict about soil requirements and can grow normally in relatively barren soil, its tolerance to waterlogging is very poor. Moreover, a high-quality soil environment is also very beneficial to the growth of weigela. Therefore, we should mainly use soil with normal drainage and irrigation, rich humus, and a deep soil layer. The soil should also have good permeability, so that weigela can grow normally and its flowering rate and flower quality can be ensured.
2. Water and fertilizer management
When growing weigela, topdressing is also very important. Before growing weigela, sufficient base fertilizer should be applied to the soil. If the base fertilizer is sufficient, then there is no need to pay too much attention to topdressing in the early stage of cultivation. Generally, topdressing once every two weeks or so during the growing season is enough, and the fertilizer is generally mainly organic fertilizer or compound fertilizer. When watering, the amount of water should be appropriately changed as the weigela grows. During the budding stage, it should be gradually increased to keep the soil moist. In summer, when temperatures are high and water evaporates quickly, attention should be paid to spraying water on the leaves to avoid yellowing of weigela leaves caused by lack of water.
3. Reasonable pruning
Weigela grows relatively fast, and its branches have relatively strong regeneration ability. Therefore, during cultivation we must also do a good job of pruning. If pruning is not done in time, then too many branches and excessively lush growth will make the interior of the plant too dense and affect the growth of the inner branches. Therefore, pruning should be carried out in winter and other times when weigela grows slowly. The main targets for pruning are spent flowers, dead branches, and branches with pests and diseases. This can not only improve the internal permeability of the plant, but also avoid consuming too many nutrients and ensure the growth capacity of weigela in the second year.
4. Precautions
When growing weigela, we should focus on controlling the temperature well. Weigela likes to grow in a warm environment. The suitable temperature should be controlled at around 20-30 degrees. During the flowering period, the temperature should be gradually lowered and kept at around 20 degrees. In summer, cooling work should be done well, and in winter, attention should be paid to cold protection and warmth. Then pest and disease prevention and control should be done well. Although weigela has relatively few diseases, it is also easily threatened by pests such as red spiders and aphids. Therefore, we should pay attention to the prevention and control of these pests to ensure the normal growth of weigela.
