1. Too much sun.
Hydrangea wilting can be caused by many things, but too much sun is one of the most common, especially during these dog days. Although it can accept direct sunlight, but the sun is too strong summer afternoon, it is best to give it shade, or pull a shading net or something. Especially when flowering, reduce direct light from noon to afternoon, otherwise the flowers will wither prematurely.
2. Insufficient moisture.
Hydrangea needs more water, soil moisture should be kept in a moist state, there can be no long-term drought. Especially in flowering, if the water is insufficient, the first thing to suffer is definitely the delicate flowers. If the current amount of watering does not guarantee the water supply of the plant, it can be divided into morning and evening watering (especially when it is very hot). Water can also be sprayed on the leaves, but do not spray water on the flowers.
3. Fat wound.
This depends on whether there has been recent fertilization. If the plant has been growing normally, the water and sunshine are also normal, and the flower wilting happens to appear shortly after fertilization, this should be considered as a problem of excessive nutrition. First of all, immediately stop fertilization, only irrigation water, so that excess nutrients with water leaching out. Do not fertilize for at least 20 days, and reduce the concentration of fertilizer in the future by half.
4. The soil is alkaline.
Hydrangea is a plant that likes acidic soil. Of course, if the pH deviation of the soil is not very large, the plant can grow as usual without influence. But sometimes the pH of the soil changes over time because the roots absorb certain nutrients from the soil. The solution is to irrigate it with ferrous sulfate solution or potassium dihydrogen sulfate solution. Usually, the effect can be seen after one or two uses, and the interval is 15-20 days.
