Product Information
Full details
The Hydrangea Querc. 'Ice Crystal' is a winter-hardy, compact oak-leaf hydrangea ideal for gardeners seeking continuous summer blooms and low maintenance. Its key benefit is its long flowering period, producing pure white flowers that mature to purple. A potential caveat is its preference for specific soil conditions (moist, acidic, well-drained). This plant offers pure white blooms from June to August, which deepen to purple in autumn, grows into a tidy shrub up to 1500mm, and is suitable for borders, cottage gardens, and containers.

Can this hydrangea tolerate frost?
Yes, the Hydrangea Querc. 'Ice Crystal' is winter-hardy and can tolerate frost once established.
What is the mature size of this plant?

Troubleshooting
Wilting leaves despite moist soil
Ensure the soil is well-drained; standing water can cause root rot. Check for any physical obstructions around the root base.
No or few flowers
Ensure the plant is receiving adequate sunlight (at least 4-6 hours). Check if it was pruned incorrectly during the dormant season (this variety blooms on old wood).
Yellowing leaves (chlorosis)
This indicates the soil may not be acidic enough. Apply an acidic fertilizer or amend the soil with ericaceous compost or sulfur.
Leaf edges turning brown
This can be due to underwatering, strong winds, or excessive sun exposure. Increase watering, provide shelter, or ensure adequate soil moisture.

Setup, Compatibility & Care
Planting:
Water the plant thoroughly before planting. Choose a location that receives sun or partial shade. Prepare the soil by ensuring it is moist, acidic, and well-drained. Dig a hole twice the width of the root ball and plant the hydrangea at the same depth it was in its original pot. Water generously after planting to help the soil settle and establish.

This hydrangea is compatible with most perennial plants and shrubs in similar soil and light conditions. It thrives in mixed borders, cottage gardens, and is well-suited for container planting.
