Double blooms! • Mophead Hydrangeas don't need pruning- just remove dead stems.
- Hydrangea bloom color depends on soil pH. Change your hydrangea blooms from pink to blue by adding aluminum to the soil and lowering its acidity (consult your local garden center).
- Cool Afternoons: Hydrangeas thrive in early morning sun and late shade.
- In the fall, once the flower petals feel 'leathery', cut long stems and hang upside down in a cool, dry, dark area and soon after, wa la! You've created ever-lasting flowers!
