2. Soil Requirements: These hydrangeas prefer well-drained, fertile soil. They can adapt to different soil types, but they thrive best in slightly acidic to neutral pH levels.

Planting Endless Summer Hydrangeas

3. Planting Time: The best time to plant Endless Summer Hydrangeas is in the spring or fall when temperatures are cooler. This allows the plants to establish roots before the stress of summer heat or winter cold.

4. Planting Depth and Spacing: Dig a hole twice as wide and as deep as the root ball. Place the hydrangea in the hole, ensuring the top of the root ball is level with the soil surface. Space multiple plants about 3-4 feet apart to allow for growth.

Watering and Mulching

5. Regular Watering: Hydrangeas need consistent moisture, especially during their first year. Water deeply once or twice a week, depending on rainfall. Ensure the soil remains evenly moist but not waterlogged.

6. Mulching Benefits: Apply a 2-3 inch layer of mulch around the base of the plant. Mulch helps retain soil moisture, regulate temperature, and suppress weeds.

Fertilizing for Optimal Growth

7. Balanced Fertilizer: Use a balanced, slow-release fertilizer formulated for hydrangeas. Apply it in early spring as new growth begins and again in mid-summer. Avoid over-fertilizing, which can lead to excessive leaf growth at the expense of blooms.

Pruning for Continuous Blooms

8. Pruning Time: Prune Endless Summer Hydrangeas in late winter or early spring before new growth starts. Remove dead or weak stems and shape the plant as needed. Light pruning after the first bloom can encourage a second wave of flowers.

Adjusting Soil pH for Desired Bloom Color

9. Color Manipulation: Endless Summer Hydrangeas can produce blue or pink blooms depending on the soil pH. For blue flowers, maintain acidic soil (pH below 6.0) by adding aluminum sulfate. For pink flowers, keep the soil more alkaline (pH above 7.0) by adding garden lime.
