The solutions to the wilted hydrangea flowers are as follows:

1. Solution to water shortage. If the bouquet falls off, but the situation is not particularly bad, you can choose to sprinkle water on the petals frequently, and then change the water in the bouquet. The water level in the container should be basically in contact with the petals. If the situation is serious, soak the entire bouquet in water until the water covers the entire bouquet. If the potted plants are short of water, water should be added to the ground in time. Also prepare a container that is larger than the potting container, add enough water to the container to cover the bottom of the pot, and then place the potted plant on top. If the situation is not optimistic, you can also use a wet paper towel to cover the soil to moisten it.

2. Solutions to excessive sunlight. At this time, you should quickly move the potted plant to a cooler place, then water the potted plant until the soil in the potted plant is completely soaked, and finally spray water on its branches and leaves.

3. Solutions to incorrect fertilization. If the situation is not particularly serious, you can water more and dilute the fertilizer. If the situation is serious, you need to cut off the branches and leaves, or even replace the potted plant with new soil.
