Planting and Spacing Tips

Plant Eclipse hydrangea in spring or fall to ensure root establishment before extreme weather. Space plants 3 to 5 feet apart to allow airflow and reduce disease risk. Dig a hole twice as wide as the root ball and place the plant at soil level, gently backfilling and watering thoroughly to settle the soil around the roots.

Watering and Fertilizing Practices

Maintain consistent soil moisture—water deeply 1-2 times weekly, adjusting for rainfall. Apply a balanced, slow-release fertilizer in early spring and a light top dressing of mulch to retain moisture and regulate temperature. Avoid over-fertilizing, which can harm blooms and promote weak growth.
