Planting Tips

Where to Plant

Blue Heaven Hydrangea thrives in locations with partial to full sun exposure. It’s ideal for garden beds, borders, or as a standalone shrub in areas that receive morning sunlight and afternoon shade.


This hydrangea variety enjoys partial to full sun but benefits from some afternoon shade, especially in hotter climates. Adequate sunlight is essential for vibrant blooms.


Blue Heaven Hydrangea prefers well-draining, moist soil rich in organic matter. Soil pH can influence the color of the blooms, with acidic soils producing bluer flowers.


Space Blue Heaven Hydrangeas about 4 to 5 feet apart. Proper spacing allows each plant enough room for growth and air circulation, fostering healthy development.

When to Plant

The optimal time for planting is in the spring or early fall. Planting during cooler temperatures helps the hydrangea establish its roots without the stress of extreme heat.

How to Plant

Dig a hole as deep and twice as wide as the root ball. Place the hydrangea in the hole, backfill with soil, and water thoroughly. The top of the root ball should be level with the ground.

Plant Care Tips


Regular watering is vital, especially during dry spells. Blue Heaven Hydrangea prefers consistently moist soil but does not like to be waterlogged.


Fertilize in early spring with a balanced, slow-release fertilizer to promote healthy growth and vibrant blooms.


Prune in late winter or early spring before new growth begins. This hydrangea blooms on new wood, so pruning stimulates healthier blooms.
