Why hydrangea blooms green and what to do
Content:
An unusual hydrangea can change the shade of its buds during the flowering period. Often, its young and already wilting buds acquire a green tone. When the growth conditions change, the bush also changes the color of its colored caps. Another reason lies in the soil and those micro- and macroelements that predominate or are absent in it.
Varieties that bloom green
The green color of the petals is also provided by the varietal characteristics of the plants. A variety on which the buds remain soft green throughout the entire flowering - Hayes Starburst. Varieties with white petals often bloom in greenish shades at the beginning of their flowering. And when they already fully open their buds, they become snow-white or cream.

- in acidic soil (up to 5.5), the flowers become blue;
- an indicator from 5.5 to 6.5 will color the inflorescences purple;
- neutral soil (average 6.5) will promote the flowering of hydrangeas in pink and cream shades.
