There are many varieties of geranium with flower colors of red, pink, white, orange, or combinations of these. Geraniums grow best in full sun in loamy, well drained soil. The plants become established more quickly if flower buds are removed at planting time. Setting the plants too deeply causes stem rot. Geraniums grow best when fertilized at regular intervals. The lower leaves turn yellow and fall from plants allowed to get too dry. Remove dead blossoms regularly. Geraniums make good pot plants. They may be overwintered in a cool, humid place by digging them in the fall, shaking off most of the soil and hanging them upside down. The storage area must be cool and humid.

Geraniums are propagated by seed or cuttings. Cuttings need at least three nodes and are usually taken in late summer. Remove the lower leaves, leaving only the tuft of leaves at the top of the cutting. Geranium cuttings root well in vermiculite. The seed germinates in one to three weeks at temperatures between 70 and 75 degrees. Cover the seed with about an eighth inch of soil. Do not allow the soil to dry out excessively.
