The citronella plant, also marketed as a mosquito plant, is really nothing more than a scented geranium. Although some suppliers claim the plant is a genetic cross between citronella grass and the geranium and works as an effective mosquito repellent, research does not support the claims. Arthur Trucker, plant fragrance specialist from Delaware State College explains that the citronella plant is actually less effective than lemon balm. It does, however, make an attractive plant that can be grown outside during the summer and brought inside for the winter. Does this Spark an idea?
Moving the Plant Inside
Citronella plants grown outside during the summer can be safely moved inside for the winter -- but should be moved inside in late summer before nights become cool. Placing the plant in a cool area of the home for two weeks to get it accustomed to inside temperatures lessens stress on the plant.
Cutting Back Foliage
Cut the foliage back to 4 to 6 inches when you bring the plant inside to encourage new growth. Scented geraniums grown in the home tend to get leggy as they stretch for light. Cutting them back and pinching out new growth from the center leaves every three to four weeks creates a dense, compact plant. Some yellowing and dropping of bottom leaves is expected and will not damage the health of the plant.
Winter Care
Place the citronella plant in a sunny southern or western window during the winter. If you choose to keep the plant inside during the summer, move it to an eastern window where the sun's rays are less intense. Water when the soil dries, but avoid either over- or under-watering. Water until the water runs freely through the bottom of the pot and allow the soil to dry slightly before watering again. Apply water-soluble fertilizer once a month during periods of active growth.
Considerations
Citronella plants release their fragrance with the slightest brush of the foliage. Placing the plant in the kitchen or dining area serves the added benefit of scenting the room. Simply brush the leaves when fragrance is desired -- or pick and bruise a leaf to release the citronella scent. Placing the plant in a high-traffic area increases the amount of fragrance released naturally during normal household activities.
