Geraniums
are so loved and so common that they hardly need a description. But there are newcomers to gardening and to growing geraniums.
Geraniums are grown as annuals only
because they do not survive frost. Grown indoors or brought inside through
the winter they can continue growing for years.
Plants grow from one to two feet
tall in one summer. Colors are red, pink, white, and purple. They have no
unusual requirements, a good well drained soil is helpful. A half day
of sunshine is fine. They are often grown in flower beds
as well as pots and hanging baskets.
Plants are usually obtained as single
plants in four inch pots or larger. The stems are also easily rooted in damp
sand or soil. Planting geranium seeds takes a long time to produce sizable plants.
There are a number of types of geraniums.
Some are grown as herbs and have scented leaves. Another type has ivy shaped
leaves and is somewhat viney, making them good for hanging baskets.
Most people grow Zonal Geraniums
in their gardens. They have bushy growth and regularly
produce may flower clusters. Geraniums can use pruning at times to keep them
looking full rather than scraggly.
Water when the soil is moderately dry to keep the leaves from turning
yellow. Old flower stalks and yellowing leaves need to be removed to keep
a good appearance. Also remove any leaves that look diseased or have insect infestations. Brown leaves may be the result of lack of water. Yellow leaves can result from too much water and not enough light. Red tinged leaves can be the result of cold weather.
Good sanitation is the best way to prevent various types of diseases:
Sanitation: Pull weeds and remove plant debris.
Use soil amendments such as sand and compost to produce well-drained soil. Avoid overhead irrigation and water early in the day.
Remove diseased plants as soon as possible.
Space plants to promote good air circulation.
Avoid unnecessary handling of plant material and wash hands frequently.
Chemical control is available but is rarely needed in landscape situations.
