Overwintering a Mosquito Plant (Citronella Geranium) Indoors

Light, Dry Soil, and Spring Pruning for Pelargonium citrosum

Mosquito plant (Pelargonium citrosum) struggles indoors due to lower light intensity. Overwinter successfully by:

• Maximizing sun (south window).
• Keeping soil dry—top quarter dry between waterings.
• Stopping fertilizer in winter.
• Keeping very potbound.
• Pruning sharply every spring to prevent legginess.

Tip cuttings root easily in water or damp mix. Start new plants each spring; discard old ones after propagation.
