Key features

• •Plant citronella outdoors once all danger of frost has passed. Choose a site with bright sunlight and, if possible, a little afternoon shade to protect the plant's delicate leaves during the hottest parts of the day.
• •Citronella plants grow best in well-drained soils. Give in-ground plants 18 to 24 inches of space between plantings. If planting in your garden, add compost to the hole when planting.
• •This plant will come back each year as a perennial in USDA Zones 10-12 and an annual elsewhere. Water infrequently, letting soil become completely dry between.
• •The citronella geranium is not to be confused with others that are also called "mosquito plant", nor with the group of plants also known as citronella grass, or with Citronella mucronata (Chilean Citronella).
• •Citronella plants can be propagated relatively easily by means of softwood cuttings, taken any time between spring and autumn.
