Recently, there is a trend toward growing geraniums from seeds. Seed propagate geraniums perform equally as well as vegetatively propagated material and produce smaller plants at less cost to the consumer. Seed propagated geraniums branch freely, are less leggy and seem to grow faster. Geraniums are at their peak of performance late winter through early summer in central and south Florida and early spring through early summer in north Florida. To ensure maximum performance, start with healthy, disease-free plants and follow proper cultural practices.
Geraniums grow best in full sun .
They will tolerate partial shade but will usually grow tall, producing fewer lateral branches and consequently, fewer flowers. They should be spaced 18 inches apart in flowerbeds. To avoid disease problems and to give a well-groomed appearance, cut off all the old flower heads. Geraniums grow best in soils that provide good drainage and aeration, and have good moisture and nutrient retention capacities. Florida's sandy soils should be amended with organic matter .
