Gerbera daisies are a tropical, perennial plant that thrives in warm climates with mild winters. Gerberas are grown directly in the garden in areas such as Florida, but can be successfully grown in pots in areas with cold winters. Gerbera daisies are short-lived, and usually need replacing every two to three years. Caring for your Gerbera daisies properly helps extend their blooms as well as keeping the plant healthy for as many years as possible.
Plant Gerbera daisies in an area that receives afternoon shade and is well-drained. Work a 2-inch layer of peat or compost into the top 10 inches of the bed before planting to encourage good draining in the area.
Set a Gerbera in the ground so the crown of the plant is slightly above or just at the level of the soil. The crown is the area where the stems emerge from the root system.
Water Gerbera daisies when the soil begins to dry out around the crown.
Lay a 2-inch layer of mulch around the plants, but not over the crown. Use organic mulch, such as bark, as this preserves soil moisture and prevents weeds.
Lift the Gerbera and replant every two years or when the crowns sink into the soil and become covered. Dig around the plant, then slide your trowel under the roots and lift the daisy from the ground. Replant it so that the crown is once again even with the soil surface.
Potted Gerbera Care
Plant Gerbera daisies in 8- to 10-inch-diameter pots filled with a soil-less potting mixture. Soil-less mixes drain better than soil mixes. Set the Gerbera in the pot so the crown is even with the potting mix.
Set the pot in an area that receives indirect, bright light, such as near a south-facing window. Place the pot in a room that remains fairly cool, preferably between 40 and 70 degrees Fahrenheit during flowering, and slightly warmer when not in flower.
Water when the top 1 inch of soil in the pot feels dry to the touch. Water until the excess moisture begins draining from the bottom of the pot.
Fertilize potted Gerbera every two weeks when the plants are actively growing. Use a balanced, liquid houseplant fertilizer, following label instructions for application amounts and method.
