Pelargonium x hortorum--Geranium


Height: 24 in Spacing: 12 in
Type: annual
Flowers: Orange, pink, purple red, white

Comments: There are many cultivars of Geranium providing a
variety of shades and combinations of the listed colors.
Geraniums grow best in full sun and 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.

Propagation: 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.
