Comprehensive Indoor Gerbera Daisy Cultivation Guide
In this article, we'll delve into the intricacies of growing and maintaining gerbera daisies, a popular choice for their vibrant, daisy-like flowers that come in a variety of colours and sizes.
Gerbera daisies thrive best when placed near a sunny window with ample indirect light. This unusual combination of bright light and moderate temperatures (40-70°F/4-21°C) is key to their growth and blooming.
For those interested in sowing seeds indoors, it's recommended to do so approximately 8-12 weeks before the last frost date in spring. High-quality, soilless potting mix should be used for seed starting, and containers should drain well and be filled with a nutrient-rich potting mix.
New plantings should be kept moist and at consistently warm temperatures, around 70°F (21°C). During periods of active growth, gerbera daisy plants need to be watered approximately 1-2 times per week, ensuring the top inch (2.5cm) of soil feels dry to the touch before watering again.
Pruning of gerbera daisy plants is seldom required, but deadheading will be beneficial to prevent the production of seed and help divert energy into new growth. Experienced growers suggest repotting gerberas annually, with new pots at least 2 inches (5cm) larger in diameter than the plant's root ball.
Gerbera daisies can also be propagated from cuttings, rooting in as little as a week, or through the removal of side shoots from established plants. They can also be shaken gently from the root mass to produce new plants.
Indoor gerbera daisies may face challenges from pests like aphids, spider mites, and thrips, and diseases such as botrytis, powdery mildew, crown rot, root rot, and fusarium, especially in containers with poor drainage. Early detection can help control their spread.
Consistent temperatures and frequent fertilization can help keep potted gerbera daisies blooming indoors. Routine feeding is especially important for potted gerberas, with water-soluble feeds most recommended throughout the spring and summer. Gerbera daisies will perform best in soils that are slightly acidic, but most indoor specimens will perform well when placed into a high-quality potting mix.
Gerbera daisies can be kept year-round as houseplants, with a potential lifespan of two to three years. During the warmer months, they can be moved outside for additional sunlight and fresh air, and overwintered indoors to protect them from frost.
Lastly, gerbera daisies benefit from consistent humidity, with plants appreciating routine misting throughout the driest parts of the year. Clear humidity domes or those designed for propagation and seed starting can help maintain ideal moisture levels.
