How do you change the color of hydrangeas? The method is actually very simple

A single cluster of hydrangeas can produce different colors. I originally thought that only different varieties would produce different color effects, but it is actually the same pot, and different colors can be created artificially!

Being able to artificially change flower color is very exciting and surprising for many people, and they cannot help but want to try it. But how exactly should it be adjusted?

The reason a single cluster of hydrangeas can have flowers of different colors is that it changes with the pH of the soil. When it encounters acid, it is blue; when it encounters alkali, it is red. If you want different colors, you can change the pH of the soil to adjust the color.

Fertilizer can change the pH of the soil, so if you want hydrangeas to bloom blue, you need to prepare the soil pH in advance. It is best to apply aluminum sulfate fertilizer ten days before the flower buds open.

To get blue-purple-pink flowers, you should delay the acid-adjusting fertilizer until after the hydrangea produces light pink flowers, then apply aluminum sulfate and vinegar water.

To get purple hydrangea flowers, you should apply acidic fertilizer before the flower buds form, and stop when the buds appear and begin to show color.

Adjusting the color of hydrangeas is actually very simple. You do not need to fertilize all four seasons; as long as you grasp the timing and find the right nodes, you can quickly achieve the color-adjusting effect.

However, when fertilizing, flower lovers must be sure to prefer dilute over concentrated, and do not apply many kinds of fertilizer at one time!
