Limelight Hydrangea performs best in locations that receive full sun to partial shade, with a preference for morning sunlight and afternoon shade in hotter climates.
It requires at least 4 hours of direct sunlight daily but appreciates some shade during the hottest part of the day to protect its blooms.
This hydrangea prefers well-drained, moist soil that is rich in organic matter. It can tolerate a range of soil pH but flourishes in slightly acidic to neutral soil.
Space Limelight Hydrangea plants 6 to 8 feet apart to accommodate their mature size and promote healthy air circulation.
The best time to plant is in early spring or fall, allowing the plant to establish itself during moderate weather conditions.
Dig a hole as deep as the root ball and twice as wide. Place the plant in the hole, backfill with soil, water thoroughly, and apply a layer of mulch.
Regular watering is crucial, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged.
Apply a slow-release, balanced fertilizer in early spring to support healthy growth and abundant blooms.
Prune in late winter or early spring, removing only dead wood and spent flowers to encourage new growth.
Apply mulch to retain moisture and fertilize as new growth appears. Prune as needed to shape the plant.
Keep the soil moist, especially in hot weather. Provide extra water during extreme heat.
Reduce watering as the plant begins to go dormant. Apply a fresh layer of mulch for winter protection.
No specific care is needed in winter. Assess the plant's health in early spring and prune accordingly.
