The Geranium Robertianum

For outdoor planting, geraniums will grow just as good in containers as they will in the garden bed.

Geraniums need 6 hours of sun every day to flourish so plant them in a spot that is at least partially sunny.

Soil conditions should be slightly acidic and well drained.

Geraniums grow nicely in patio containers and planters. Make sure you use a soil mixture that drains well (soil and peat moss or perlite) and do not over water. It is important to keep your plant in a container that is large enough to support growth or you will find the plant will wilt and look unhealthy.

Indoors, geraniums will flower better if you keep them in a sunny spot. They prefer temperatures around 65 degrees during the day and 55 degrees at night. Use a well drained potting mix and fertilize monthly in the spring summer and every 2 months in fall and winter.
