What requirements must be met to grow Gerbera daisies?
Gerbera daisy growing methods -- temperature requirements for Gerbera daisies, temperature requirements, watering requirements, topdressing requirements; see details below. If you can carefully pay attention to the points above, it will not be difficult to grow a beautiful Gerbera daisy.
1. Temperature requirements. Use cultivation facilities and try to meet the temperature requirements of Gerbera daisies at the seedling stage, growth stage and flowering stage, so as to facilitate normal growth and flowering. Except in South China, they cannot overwinter outdoors and need greenhouse cultivation; outside the Yangtze River Basin, they can be grown in unheated plastic tunnels. In summer, shade netting needs to be covered on top of the tunnel, and the plastic film on both sides of the tunnel should be opened to lower the temperature. In winter, when the outdoor night temperature is close to 0C, seal the plastic film tightly, and an additional layer of plastic film must be added inside the tunnel. On clear and warm days, open the film at the south end of the tunnel at noon for ventilation for about one hour.
2. Temperature requirements. Gerbera daisy is a light-loving flower and needs full light in winter, but in summer attention should be paid to appropriate shading and enhanced ventilation to lower the temperature and prevent dormancy caused by high temperatures.
3. Watering requirements. After planting, the seedling stage should remain appropriately moist and the seedlings should be hardened to promote root development and rapid establishment. During vigorous growth, sufficient water should be maintained, watering once every 3-4 days in summer and about once every half month in winter. When watering during the flowering period, be careful not to let water touch the center of the leaf rosette, to prevent flower buds from rotting. When growing in the open field, pay attention to preventing waterlogging. In addition, watering can be combined with fertilization.
4. Topdressing requirements. Gerbera daisy is a fertilizer-loving perennial herbaceous flower with a high demand for fertilizer. The ratio of nitrogen, phosphorus and potassium in fertilization is 15:18:25. When topdressing, special attention should be paid to supplementing potassium fertilizer. Generally, apply 2.5 kg of potassium nitrate, 1.2 kg of ammonium nitrate or ammonium phosphate per mu, once every 5-6 days in spring and autumn, and once every 10 days in winter and summer. If high temperatures or relatively low temperatures cause the plant to enter a semi-dormant state, stop fertilizing.
5. Management of soil, fertilizer and water in Gerbera daisy cultivation. Gerbera daisy is not strict about soil and prefers slightly acidic soil with a pH of 6.0-6.5. It can also grow and bloom in neutral or slightly alkaline soil, but in alkaline soil the leaves are prone to chlorosis. A loose, breathable, humus-rich sandy loam is suitable. Generally, choose materials with good permeability such as pine needles, rice husks and chaff, and mix them with decomposed organic fertilizer (such as pig manure, cow manure, etc.) and sandy soil, with a volume ratio of about 1:1:1. After mixing evenly with broad-spectrum fungicides such as carbendazim and mancozeb, cover with plastic film for 3-5d, uncover the film and turn the mixture, and use it after the medicinal smell has volatilized. In addition to a high demand for nitrogen, phosphorus and potassium, potted Gerbera daisies also have a relatively high demand for magnesium, so during the growing season, a foliar spray of 0.2%-0.4% physiologically acidic fertilizer mainly consisting of ammonium nitrate, superphosphate, potassium sulfate and magnesium sulfate should be applied once every 2-3 weeks; it can also be combined with watering by irrigating with dilute alum fertilizer water. In autumn and winter, the interval can be longer, the concentration should be reduced, and phosphorus fertilizer should be appropriately increased to enhance the plant's cold resistance. Potted Gerbera daisies are relatively drought-tolerant and afraid of water accumulation, and water accumulation easily causes root rot. When watering and fertilizing, try not to let water touch the center of the leaf rosette, otherwise the flower buds are prone to rot. The water temperature should be slightly higher than the soil temperature, otherwise it may become infected with damping-off disease.
What are the growing methods for Gerbera daisies? What precautions are there for growing Gerbera daisies?
Basic information about Gerbera daisy:Gerbera daisy, Asteraceae, also known as fringed flower, sun flower, gorilla daisy, day flower, etc., is a perennial herbaceous plant with terminal inflorescences. The flower colors include red, white, yellow, orange, purple, etc. Propagation is by sowing or division. Its place of origin is South Africa.
Because Gerbera daisy originated in South Africa, it likes an environment that is warm in winter and cool in summer, with air circulation and sufficient sunlight. It is not cold-tolerant and avoids intense heat. Gerbera daisy is a light-loving flower and needs full light in winter, but in summer attention should be paid to appropriate shading and enhanced ventilation. The suitable growth temperature is 20C--25C during the day and about 16C at night, and the suitable flowering temperature is not lower than 15C. It likes fertile, loose, well-drained, humus-rich sandy loam, avoids heavy clay soil, and prefers slightly acidic soil. The optimum pH for growth is 6.0-9.0.
What are the growing methods for Gerbera daisies:Because Gerbera daisy has brilliant flower colors and is inexpensive, it has become the first choice for household fresh cut flowers in vases. Gerbera daisy requires loose, fertile, well-drained, humus-rich, deep, slightly acidic sandy loam. In summer, attention should be paid to appropriate shading and enhanced ventilation to lower the temperature and prevent dormancy caused by high temperatures. It is not sensitive to photoperiod, and the length of natural daylight has no effect on flower number and flower quality.
Gerbera daisy growing method 1. Soil: Gerbera daisy likes humus-rich, well-drained sandy loam with a pH of 6?6.5. For pot cultivation, slightly acidic culture soil can be used; for ground cultivation, pay attention to using well-drained fertile soil. It can be prepared with 3 parts garden soil, 3 parts peat soil, 3 parts leaf mold and 2 parts sand, or with 4 parts peat soil, 3 parts leaf mold, 2 parts sand and 1 part perlite.
Gerbera daisy growing method 2. Temperature: The suitable growth temperature is 20?25 degrees, the suitable germination temperature is 18-20°C, the suitable temperature for winter dormancy is 12?15°C, and growth stops below 7°C.
Gerbera daisy growing method 3. Light: Whether potted or planted in the ground, it should be placed in a place with sufficient light so that it can grow robustly and have bright flower colors. If light is insufficient, development will be poor, and the flowers will be small and pale.
Gerbera daisy growing method 4. Watering: Gerbera daisy likes moist soil, is afraid of waterlogging, and is afraid of drought. During the growing periods from March to June and from September to October, water more, but do not let water accumulate; keeping it moist is appropriate. In winter, when the temperature is below 12 "C, water less, and slightly on the dry side is better.
Gerbera daisy growing method 5. Fertilizer: Gerbera daisy is extremely fond of fertilizer. When fertilizer is sufficient, growth and flowering are vigorous. Therefore, sufficient base fertilizer should be applied before planting, and after planting from June to October, a thin application of decomposed cake fertilizer water can be applied once every half month.
Gerbera daisy growing method 6. Pests and diseases: The diseases of Gerbera daisy include leaf spot, powdery mildew and viral disease. For leaf spot, spray with 70% thiophanate-methyl wettable powder at 800-**** times dilution or 50% carbendazim wettable powder at 500 times dilution. For powdery mildew, use 70% thiophanate-methyl at 1500 times dilution or 75% triadimefon wettable powder at 1000-1200 times dilution for control, once every 7-10 days, spraying two to three times continuously.
Gerbera daisy growing method 7. Pruning: The lower leaves of the basal leaf rosette of Gerbera daisy easily turn yellow and age, and should be removed in time, which is beneficial both to the sprouting of new leaves and new flower buds and to ventilation, enhancing plant vigor. In addition, if the branches and leaves are too luxuriant and shade each other so that air does not circulate, part of the leaves can be appropriately removed.
Precautions for growing Gerbera daisies:Precaution 1 for growing Gerbera daisies: When fertilizing, do not let the fertilizer solution spread to the center of the daisy, otherwise the growth point in the center is prone to rot and death; also do not let the fertilizer solution splash onto the leaf surface, otherwise the leaves will be burned.
Precaution 2 for growing Gerbera daisies: Gerbera daisy is relatively sensitive to temperature and light intensity. In summer, keep the soil moist and not drought-stressed, cover with a shade net with 50% light transmittance, and spray the leaf surface to increase air humidity and lower the temperature.
Precaution 3 for growing Gerbera daisies: In winter, sufficient warmth should be provided and the plant should not be frozen. The nighttime temperature should not be lower than 10°C, and the daytime temperature should not be lower than 15°C. These are all very beneficial for improving the brightness of Gerbera daisies.
