1, soil disturbance: geranium requires fertile soil and good drainage. Potted soil can be humus soil, chaff ash and garden soil of1/,and a small amount of calcium superphosphate can be added for mixing.
2, watering: geranium is drought-resistant and afraid of water accumulation. Therefore, in the process of growth, we should control the water properly in the spirit of "dry without watering, pouring without penetration, rather dry without wetting". Too much watering and too much water in the basin soil will cause overgrowth or root rot. When blooming vigorously in spring and autumn, you can water more appropriately, but you should also keep the basin soil moist. In winter, the temperature is low and plants grow slowly, so water them as little as possible.
3. Lighting: Geranium is native to South Africa and likes sunny, warm and well-ventilated environmental conditions. When the light is not too strong in spring and early summer, you can put the flowerpot in a well-lit place to receive enough light. But in the hot season of midsummer and early autumn, it should be placed in a cool place to avoid direct sunlight, otherwise it will burn branches and leaves.
4. Temperature: the optimum growth temperature is 15-25 degrees, which is not resistant to high temperature and has poor growth in summer.
5. Fertilization: In cultivation, in addition to applying sufficient base fertilizer, in the growing season, especially in the flowering period, 1 diluted liquid fertilizer can be applied every 7- 10 days. It is best to dilute it with decomposed livestock manure and water, or to fertilize it with decomposed cake. 3-5 days before fertilization, less or no watering, watering when the pot soil is dry, is more conducive to root absorption.
6. Pruning: In order to make the plants beautiful and bloom more, if the plants grow too vigorously in spring, they can be pruned. Cut off the residual flowers and over-dense branches in time after flowering. During the dormancy period, 1 pruning was also carried out, to cut off the old leaves that were yellow, to sparse the branches that were too dense, and to shorten the branches that were too long, so that after the dormancy period, new branches were produced and continued to bloom. In addition, geranium itself has a special smell and rarely suffers from pests. So there's no need to take precautions.
