Office Hydrangea Care: Water, Light, and Annual Soil Refresh

Keeping a Potted Hydrangea Alive Indoors

You have a hydrangea in your office—constant fluorescent light, cool temps, not great at plant care. You want simple instructions.

The Basics

• Water: Keep soil evenly damp (not wet). Check every 2–3 days. Water until it drains; empty saucer.
• Light: Medium indirect light is fine. No direct sun through glass (can scorch).
• Pruning: Snip off spent blooms just above a leaf node to encourage new buds.
• Soil refresh: Once a year (spring), repot with fresh potting mix. Add 1 inch gravel at bottom for drainage.
• Fertilize: Monthly, half-strength balanced liquid (Miracle-Gro, Peters). Stop in fall.

Flower Color Note

Bloom color (pink vs. blue) depends on soil pH. In a pot, you can control it: acidic soil (add sulfur) = blue; alkaline (add lime) = pink. But don’t overcomplicate—enjoy whatever color appears.

Common Pitfalls

• Overwatering (soggy soil = root rot).
• Letting it dry out completely (wilting = bud drop).
• Hot/cold drafts from vents.

With consistent moisture, monthly feeding, and an annual soil change, your office hydrangea can bloom for months.
