I can't keep a secret .....
I was at the Nursery today buying some flowers for my garden when I overheard someone asking if coffee grounds were safe to use on hydrangeas?
My ears perked up and guess what??
Yes It is true you can use coffee grounds around your hydrangeas to help turn them from pink to blue.
Something to do with the acid in the soil. I have always used nails too to change the color of the flowers but I forgot this year to put the nails in the ground.
I have huge pink blooms but I would love to get them blue like the blooms in Martha's Vineyard.
I also learned that coffee grounds are great for Roses too.
I will be drinking alot more coffee now that I know.
