How to Make a Mosquito Plant Become Full

The mosquito plant emits a citronella fragrance at the slightest brush of the leaves giving rise to the thought that it repels mosquitoes. Although this may hold some truth, this scented geranium is no more effective against mosquitoes than lemon balm or lemon thyme, reports Donald Lewis from the Iowa State University Entomology Department. However, its lacy foliage and citrus scent makes this scented geranium an attractive houseplant. With proper care, it produces dense, compact foliage with pink blooms.

Instructions

    • 1

      Pinch out the growing tips on the mosquito plant when it is 4 to 6 inches tall. This forces branching between the leaf nodes and encourages dense foliage.

    • 2

      Place the mosquito plant in an area that receives full sun. In southern locations, it may benefit from some shade during midday, but this plant typically thrives in full sun. Plants that do not receive enough sunlight produce tall, lanky stalks as they stretch for sunlight.

    • 3

      Pinch out growing tips again once new growth has reached a length of 4 to 5 inches. This encourages further branching. Repeat with new growth as necessary until the plant reaches the desired appearance.

    • 4

      Trim overgrown mosquito plants back to 4 or 5 inches in height, if foliage is sparse or stems are elongated. This revitalizes the plant and spurs a flush of new growth.

    • 5

      Water the plant until water runs freely through the bottom of the pot when the soil feels dry 1 inch below the surface. Allow the soil to dry slightly before watering again.

    • 6

      Apply water-soluble fertilize once a month during periods of active growth, typically between March and September. Reduce fertilizer to once every other month during the winter months.
