Grow geraniums in a soil medium that is high in organic material. A good soil mix consists of equal parts garden loam, peat moss and coarse sand or perlite. Other mixes can work equally well. Commercial soil mixes also may be satisfactory. Allow the soil to become moderately dry between waterings, and make sure there is one or more bottom holes in each container.
Good drainage is essential.
Outdoor Care Geraniums should not be planted outdoors until the danger of frost is past. They do best in a location with six to eight hours of sunlight per day. When planted in areas of moderate shade, flowering is reduced. Geranium plants tend to break and wilt in windy locations so, if possible, protect the plants from strong wind. The soil should be well drained with adequate organic matter.
