Indoor Hydrangea 'Brestenburg' Care: Light, Watering, and Common Mistakes

A newly purchased Hydrangea 'Brestenburg' is wilting and dropping branches in a sunny apartment. The owner waters daily and wonders if this helps or harms.

Why It's Struggling Indoors

Even a "sunny" apartment provides only shaded light—hydrangeas need several hours of direct sun on their leaves (early morning or late afternoon). Indoors, they often receive insufficient light, causing weak growth and excessive water retention.

Correct Watering Method

Overwatering is the primary issue. Use a bamboo skewer inserted to the pot bottom to monitor moisture:

1. Insert skewer, cut ½ inch above soil line.
2. When checking, pull it out—if the top half is dry, water thoroughly.
3. Moisten most of the soil but avoid filling the drain tray.
4. Empty the tray after one hour (use a turkey baster if needed).
5. Water only every 2 weeks or less in low light.

Key Takeaways

• Daily watering in low light causes root rot.
• Move to the brightest possible spot (direct sun if available).
• Let soil dry deeply between waterings.
• If placed outdoors on a patio/balcony, water needs increase.
