Potted gerbera daisies will bloom at any time of the year in shades of red, yellow, orange or white. The flowers grow at the top of long, thin stems with vivid, symmetrical petals. Technically, gerbera daisies are perennials, but they are commonly treated like annuals. With certain tricks and techniques, it's possible to keep gerbera daisy blooms thriving for a long time, even to make them reflower within a single season.
Plant gerbera daisies in well-drained soil, and fertilise them monthly while they are in bloom. In hot climates, plant gerberas in a spot where they will receive partial shade. In cooler regions, the flowers should be placed in an area where they will get the benefit of full sunlight. Raise garden beds by creating soil mounds in garden beds with poor drainage. Amend nutrient-poor soils with peat or compost to provide the flowers with the rich soil they need. Proper planting conditions encourage healthy gerbera blooms.
Gerbera daisies are often replanted after one year, but they will last two to three years under good conditions. The flowers will stay in bloom for several weeks after they initially appear. To preserve them and keep blooms bright and attractive, keep them in a temperature range of 4.44 to 21.1 degrees Celsius. Summer heat will often end gerbera blooms early; some gardeners transfer them indoors after they bloom to enjoy the flowers longer.
Even under optimal conditions, gerbera blossoms will not last until winter. After blooms die, cut them off the plant with sharp garden shears. When weather and planting conditions are right, the flowers will re-bloom so you can enjoy more gerberas. Plants are not likely to bloom more than twice in a single season, but it is common for gerberas to flower twice during spring and summer.
Indoor gerberas are easy to grow, as gardeners can exercise complete control over the plant's environment. Weather will have little effect on the plants when they are grown indoors. Potted gerberas are easy to care for, but it is still advisable for gardeners to replace the flowers every year or two.
