Step-by-Step Smooth Hydrangea Care & Diagnostic Protocol

AI Doctor Protocol
1

Calibrate Light Exposure & Orientation

Place Smooth Hydrangea in an area with partial sun to full sun. If leaf tips turn crispy brown, move away from direct southern sun. If stems become leggy, increase light levels.

2

Soil Moisture & Drainage Check

Always test soil moisture 2 inches beneath the surface before watering (keep soil moist). Ensure pots have adequate drainage holes to prevent moisture stagnation and root rot.

3

Pest & Disease Inspection

Examine leaf undersides for webbing (spider mites) or powdery white residue (mildew). If yellowing leaves or dark necrotic spots appear, isolate the plant immediately to avoid fungal spread.
