acid / base relationship to hydrangeas
Hi Robert,
I have a hydrangea plant and have successfully changed its color by changing the soil pH. Just wanted to let you know that the pH relation to the color is the opposite of what you state in the video -- more acidic soil produces bluer flowers, while alkaline soils make blooms pinker.
food color
if you put food color in water and put any white flower in the water....the veins will turn the color of the food coloring....just so you know
its pretty cool
