| Do you guys offer free soil testing like Calloways? I missed their deadline and was hoping you guys offer that. Also, what kind of soil do hydrangeas grow best in? |
| Home Depot does not offer free soil testing but there are local labs that can run tests for you. Hydrangeas will grow in a wide range of soil pH, but prefer a somewhat neutral soil. If your soil is acidic, the flowers will turn blue; if it is alkaline, the flowers will turn pink. |
