Gerbera Seed Germination and Planting Methods and Precautions Explained in Detail
Gerbera is a type of chrysanthemum, and it is currently distributed quite widely in our country. It is a plant grown for its flowers, and its blooms are commonly bright red, very eye-catching. Nowadays, many people grow gerberas, and the most commonly used method is growing from seed, so what techniques are there when planting?
How to germinate gerbera seeds
1. Select high-quality, plump gerbera seeds.
2. Choose flat terrain with plenty of sunlight and fertile soil for sowing and raising seedlings.
3. Prepare the soil in advance, remove weeds, apply fertilizer, and water.
4. Keep the sowing depth at about 2 cm.
5. 20-25°C is the temperature at which seeds germinate most easily. At this temperature, they usually sprout 3-7 days after sowing.
Gerbera Seed Planting Methods and Precautions
I. Planting methods:
1. Potting soil: Moss rose is not picky about soil and tolerates poor soil, so the soil for moss rose can be relatively flexible. If conditions allow, loose and fertile soil is best.
2. Time: Generally, sowing can be done in spring, summer, and autumn. In most cases, sowing is done in spring. In the Jiangsu-Zhejiang-Shanghai region, sowing can begin around mid-April. Gardeners farther south or north can adjust the timing accordingly. Generally speaking, once the average minimum temperature is around 18°C, sowing can begin.
3. Sowing: Evenly scatter the moss rose seeds on the soil surface, then cover with a thin layer of fine soil; there is no need to bury them deeply. After sowing, if you have a spray bottle, you can gently spray the surface, but be sure not to wash the seeds out. Other methods are also fine; it does not matter, as long as the seeds are not washed out.
4. Covering with film: If the temperature is not very high at sowing time, you can put a transparent plastic bag or cling film over the flowerpot. This helps create a high-temperature, high-humidity environment that aids germination.
II. Precautions:
1. Gerbera is relatively sensitive to temperature and light intensity. In summer, keep the soil moist and prevent drought, cover with a shade net with 50% light transmittance, and spray the leaves to increase air humidity and lower the temperature.
2. In winter, do sufficient work to keep warm and prevent freezing. 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 vividness of gerberas.
Management of Gerbera During the Flowering Period
1. After about 3-4 months, they enter the flowering period. Apply a compound fertilizer with N:P:K=12:12:17 once every 1 week. For foliar application of micronutrients, generally once every 25 days, each time use 0.1-0.2% Ca(NO3)2.4H2O, 0.1-0.2% chelated iron plus 0.1-0.2% borax plus 5-10 ppm sodium molybdate for alternating foliar spraying.
2. Use drip irrigation for watering. The watering principle is “do not water until dry, and water thoroughly when watering.” Never water from the leaf rosette. Keep the relative humidity in the greenhouse at 80%-85%.
3. Pull weeds promptly, remove diseased leaves and dead leaves, pull out diseased plants, and use quicklime to disinfect the soil in the planting holes. During the summer flowering period, pay attention to shading, ventilation, and cooling. During the winter flowering period, pay attention to keeping warm and heating, especially preventing too large a temperature difference between day and night, to reduce the production of deformed flowers.
Gerbera Diseases and Their Control
1. Leaf spot disease. Leaf spot disease is a bacterial disease. It is generally caused by pathogens spread through rain and insects. When leaf spot disease occurs, promptly remove diseased leaves and spray a solution of thiophanate-methyl wettable powder for treatment.
2. Mosaic disease. Gerberas can also suffer from mosaic disease. When mosaic disease occurs, the leaves of the gerbera fade in color, become deformed, and develop patches, and it affects flowering or causes the plant to die. When mosaic disease occurs, promptly spray a chemical treatment.
3. Powdery mildew. When powdery mildew breaks out on gerberas, it mainly harms the leaves, causing white spots that gradually expand. Powdery mildew on gerberas is mostly caused by pathogens, and it tends to break out when the temperature is high and ventilation is poor. When powdery mildew occurs, promptly improve the growing environment and spray chemicals, such as a 1500-fold solution of 70% thiophanate-methyl.
If gerbera seeds are to germinate quickly, the conditions for seed germination must be met. Generally, it starts with seed selection, and after that, care is needed. Especially when they enter the flowering period, deformed flowers are very likely to occur due to improper cultivation, so effort must be put into management.
