Endless Summer Hydrangea

How do I turn my Endless Summer Hydrangea Pink or Blue?

Soil with a pH below 6.0 (acidic soil) will produce blue hydrangea flowers and a pH above 6.0 will produce pink hydrangea flowers. A pH right at 6.0 will produce variations of blue and pink that can sometimes lean purple.

Use our Soil Test kit to test your soil pH. Our Espoma Soil Acifidier can make your soil more acidic. Or, you can use garden lime to make your soil more basic, resulting in pink hydrangea flowers.

How and when to prune Endless Summer Hydrangeas

Perennial hydrangeas bloom on new growth and previous year’s growth, enabling them to rebloom throughout the summer. Be cautious when pruning, as excessive trimming can remove future blooms. If you’re shaping the plant or cutting blooms for arrangements, avoid over-pruning to ensure a vibrant display of flowers next season.

These hydrangeas should be pruned in late summer after the blooming period ends. This timing ensures you preserve the old growth, which is crucial for flower production the following year while encouraging new growth for continuous blooms. Avoid heavy pruning to prevent reducing next year's flowers.

Do Endless Summer Hydrangeas like sun or shade?

In colder regions (USDA Zones 4-5a), hydrangeas can tolerate more sunlight, while southern areas prefer less intense sun exposure. Ideally, plant your hydrangeas where they’ll get full morning sun with dappled shade in the afternoon. For southern climates, aim for 2-3 hours of morning sun followed by part shade during the hotter parts of the day. This balance ensures healthy growth and vibrant blooms.

Where is the best place to plant Endless Summer Hydrangeas?

The best place to plant an Endless Summer Hydrangea is in a location that offers morning sun and afternoon shade. These hydrangeas thrive in well-draining, nutrient-rich soil with consistent moisture. In warmer climates, ensure the plant is shielded from the intense afternoon sun to prevent stress.
