Gerbera daisies are difficult to start from seed, so it is best to buy bedding plants in spring for transplanting into your garden. They are native to South Africa and grow as perennials in similar hot climates. In cool northern areas with severe winters, they are grown as annuals.
Plant gerbera daisies in full sun in soil that is well drained. Position them at least 24 inches apart. Dig a hole the approximate size of the root ball and insert the root ball. Firm the soil around it. Plant gerbera daisies so the crowns are about ¼ inch above the surface of the soil.
Water thoroughly and regularly. Provide your gerbera daisies with the equivalent of an inch of water per week.
Spread a 2- to 3-inch layer of mulch around the plants. Use hay, straw or buckwheat hulls. Mulch will conserve moisture and discourage weeds from growing.
Fertilize weekly with water soluble fertilizer specially formulated for flowers or African violets. Follow manufacturer's instructions as to quantity and specific mixture.
Remove faded flowers and wilted leaves to encourage the plants to produce more blooms.
In USDA Zone 8 and warmer, divide plants when they become crowded in their bed, leaving 2 to 3 flower buds on each division. Drive a spade into the plant to separate it, making sure each division has both buds and roots. Divide gerbera daisies in early spring, between February and April, depending on your location.
