Gerberas must be in a pot with at least one drainage hole to avoid root rot, crown rot, and powdery mildew which occur when the soil is constantly wet and the plant is sitting in water. However, having even more holes on the bottom will be even better. It's best to have fresh, high-quality potting soil.  Fill the container with about 3 inches (7.6 cm) of the soil. Put in the plant and add more soil until the crown (where the stem meets the roots) is slightly above the soil. Don't cover the crown, or your daisy is likely to suffocate. Modern soils allow water to flow out of the drainage holes rather than be retained at the roots. This is necessary so that your plant doesn't experience root rot or other diseases. Near a sunny window, there's adequate sunlight, but the temperatures may be too high and end up burning the leaves. However, without enough sunlight, you'll have plenty of leaves but no blooms. Morning sunlight is ideal, but be sure to keep you gerbera out of bright light during the afternoon. They can tolerate cool temperatures, but find it hard to survive in temperatures higher than 70 °F (21 °C). If your plant is located in indirect light, make sure it gets it the whole day. Turn on overhead lights or other lamps nearby, particularly during the winter. If the soil is still moist, leave the plant for a day or two. Thoroughly soak the roots of the plant, but keep the leaves as dry as possible. Make sure the pot is thoroughly drained before putting it back on a saucer or drip tray. Otherwise, the plant's roots may rot in the soggy soil. During the winter months, you should water it less often, but avoid letting the soil dry out completely. For indoor plants, it's best to use a fertilizer that is formulated for blooming parts. Follow the instructions on the package as to how much fertilizer to use based on the size of your container. Fertilize your daisy during the growing season (mid-spring to early summer), but avoid doing so otherwise. As the flowers start to wilt and fade, pinch or cut off the stem just next to the flower. Do this with all the dead or dying flowers on the gerbera. This is also referred to as deadheading the plant and will focus the development of the plant into growing more beautiful blossoms rather than producing seeds. It maintains the plant's appearance while also potentially allowing the second bunch of flowers to come out.  Bugs may pester your gerbera if you do not deadhead it. Start doing this early, such as around late spring, and repeat the process every couple of days to keep your plant in the best shape possible. If you'd like to keep flowers in a vase, cut them off when they're still fresh and keep them in water. They should last for several days. Once the plant begins looking crowded in its pot, it will need to have more space. Pick a pot that's a size larger than your current one with at least one (preferably more) drainage hole at the bottom. Fill it with 3 inches of potting soil. Hold the stem with your fingers while also covering the top of the pot and turn it upside down. The plant along with some soil should slide out, but if it doesn't, you can knock the pot against another surface to turn the plant loose. Transfer the plant to the larger pot and add soil until the top of the roots sit an inch lower than the rim of the pot. Water your replanted gerbera daisy until it begins dripping from the drainage hole(s).  When you take the daisy out, you can examine the roots. Trim off any that appear diseased or rotten. Don't cover the crown (where the main stem meets the roots) when adding soil. The plant might wilt slightly following the repot, but will perk up again within a week or two with proper care. Although gerberas don't survive repotting very well because they have deep root systems, suffocating them in a small pot will not help either. Gerberas may be infested by common household pests like mites or aphids. Spray your plant with an insecticidal soap according to the manufacturer's instructions. Monitor your plants carefully so that you can tackle the problem before they take over and the problem gets severe. You may use an organic insecticidal soap if you wish.
Pick a container with good drainage. Add the ideal potting soil mix. Keep your plant in a spot with enough light. Water your gerbera deeply whenever the top inch of soil feels dry to the touch. Use fertilizer to give your plants a boost in growth. Remove wilted blooms. Repot your gerbera if it begins to multiply. Deal with pests that infest your plant.
