Step-by-Step Stiff Verbena Care & Diagnostic Protocol
AI Doctor ProtocolCalibrate Light Exposure & Orientation
Place Stiff Verbena in an area with full sun. If leaf tips turn crispy brown, move away from direct southern sun. If stems become leggy, increase light levels.
Soil Moisture & Drainage Check
Always test soil moisture 2 inches beneath the surface before watering (moderate). Ensure pots have adequate drainage holes to prevent moisture stagnation and root rot.
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.
