Pink Hydrangea flowers do NOT turn BLUE! WHY? (我的第一朵盆栽绣球花调色尝试)
Hydrangea plants propagated by ground layering technique were grown in the container, now one Hydrangea plant is blooming, and which produces pink flowers. Two chemicals including Ferrous Sulfate and Aluminum Sulfate were periodically and alternatively applied on these Hydrangea plants to decrease soil pH value and increase acidity of soil environment starting from 09/02/2020 when I first time saw very tiny flower buds. As of 10/25/2020, the Hydrangea flowers still show pink color.
