The invention provides a method for changing the color of hydrangea, comprising the following steps: (1) selecting a healthy hydrangea plant; (2) selecting a mixed soil of red soil and humus soil for planting hydrangea; (3) selecting a mixed soil containing N , P, and K NPK fertilizers for fertilization, and the weight ratio is N:P:K=(5-10):(5-10):30. Compared with the prior art, the hydrangea discoloration method of the present invention can not only avoid the phenomena such as soil acidification and sulfur element increase caused by the application of aluminum sulfate, but the most important thing is that the specific ratio of N, P, and K in the fertilizer can effectively use The color of the hydrangea has changed to blue, and the buds have increased significantly. In addition, NPK is a large amount of elements required by plants, and the use of the NPK fertilizer of the present invention will not cause negative effects on plant growth.

Problems solved by technology

[0004] At present, the discoloration of hydrangeas is mainly caused by watering aluminum sulfate, but aluminum sulfate is an acidic substance. If it is applied too much, it will have a negative impact on the texture of the soil and other substances in the soil, and increase the amount of sulfur, which will affect the growth of plants. Growth, and the application of aluminum sulfate will only deepen the blue color of the hydrangea, and cannot achieve the effect of completely changing the color
