Geraniums are popular annual garden plants which are upright, round, and grow one to two feet in height. Leaves are opposite, simple, have serrate margins, and are two to four inches long. When crushed, a geranium leaf has a spicy scent. Flowers are in rounded umbels four to six inches across. The individual flowers have five petals. They can be red, pink, salmon, or white.
Geraniums are able to withstand some dryness. In fact, it is important not to over-water them, especially cuttings and young plants. To avoid root rot, water them only when the soil around them begins to dry out. Watch those geraniums in clay containers in the hot sun. They are likely to dry out faster than those in the garden. If possible water by hand or drip system to avoid wetting the blossoms. They deteriorate quickly when soaked.
After geranium plants flower, remove faded flower heads, their stems and any yellowed leaves promptly. Regularly pinch or cut back long stems to encourage the plant to become bushy and compact.
