Sowing time of geranium
The sowing time of geranium can be carried out in both spring and autumn. Indoor pot sowing in spring is better, the optimum temperature for germination is 20: 25 ℃, the seed is not large, the soil cover should not be deep after sowing, it can germinate in about 14-21 days, and it can blossom in summer in the second year of autumn sowing. After sowing and propagation, excellent intermediate varieties can be selected and bred.
Sowing method of geranium
The medium for sowing and propagation of geranium was mixed with peat soil, vermiculite and perlite according to 8 ∶ 1 ∶ 1. Before sowing, the substrate was watered, and then the seeds were evenly sown in the seedling plate, covered with vermiculite, and the thickness was about 3 times of the seed diameter. Disinfect the sowing box with chlorothalonil, build arch shed and cover with plastic film. The temperature is 20 ℃ to 23 ℃ and the humidity is above 95%. When sprouting evenly in a week or so, lift off the plastic film. Due to the lack of nutrients in the seedling substrate, foliar fertilizer can be sprayed every 10 days, and the compound fertilizer with relatively high content of phosphorus and potassium can be selected.
Management of pelargonium at seedling stage
1. Temperature: the most suitable temperature for geranium is 10-20 ℃, that is, spring and autumn is the most suitable, too cold in winter and too hot in summer. So in summer, you must prevent the sun from being exposed to the sun and put it in a cool place. In winter, the indoor temperature should not be lower than 0 ℃, otherwise it will be frostbitten. If there is no warm equipment, turning on a 200 °big light bulb in a small room also has a certain anti-freezing effect.
2. Moisture: geraniums are taboo to be overwatered. If the roots of geraniums are found to fester, it may be due to overwatering and muggy weather. The frequency of watering is controlled to be watered once every three or two days, with a large amount of water each time to ensure that it is thoroughly watered.
3. Soil: geranium is suitable to survive in sandy soil, and the soil bought in the flower market mixed with some sandy soil is more beneficial to the growth of geranium.
4. Weather: the windy weather will blow the geranium, while the heavy rain will make the roots of the geranium soaked by Rain Water, causing the roots to breathe anoxia and fester.
6. Fertilization: applying too much fertilizer at one time will cause dehydration of the geranium. If you apply too much fertilizer, such as applying too much nitrogen fertilizer, the plant will grow too fast and will not blossom. Too much fertilization and logistical watering can relieve the symptoms.
7, light: sufficient sunlight helps geranium blossom, but if the temperature is too high, it is not suitable for direct sunlight. In spring and autumn, pay attention to the temperature. If the temperature is too high, you should avoid making the geranium receive light.
