Pot culture method of pelargonium

1. Soil: geranium has strong adaptability and can grow in all kinds of soil, but the sandy loam soil rich in humus grows best.

2. Watering: geraniums like dryness, hate dampness, and should not be watered too much in winter. When the soil is wet, the stem is tender, which is not conducive to the sprouting and opening of flower branches. long-term excessive humidity will cause the plant to grow too long, the position of the flower branch will move up, and the leaves will gradually yellow and fall off.

3. Sunshine: geraniums need plenty of sunlight during their growing season, so they must be placed in the sun in winter. Lack of light, long stems and leaves, soft pedicels, dysplastic inflorescences, buds often bloom poorly in low light and wither ahead of time.

4. Temperature: the geranium likes to be warm in winter and cool in summer. It can blossom normally when the indoor temperature is kept at 10: 15 ℃ every day in winter and the temperature at night is above 8 ℃. But the optimum temperature is 15-20 ℃.

5, fertilization: geraniums do not like big fertilizer, too much fertilizer will make geraniums grow too prosperous and not conducive to flowering. In order to bloom luxuriantly, watering dilute book fertilizer water (rotten bean cake water) once every 2 weeks can promote normal flowering by watering 800 times potassium dihydrogen phosphate solution every 7 to 10 days.

6. Insect pests: geraniums are poorly ventilated and too humid, and are prone to leaf spot and Fusarium wilt. After discovery, pay attention to ventilation, immediately remove sick flowers and leaves to prevent infection, and spray the same amount of Bordeaux solution to prevent and cure. The main pests are red spiders and whitefly, which can be sprayed with 1000 times of omethoate emulsion.

7. Pruning: pruning in order to promote more flowering of the geranium with more branches, it is necessary to pick the heart of the plant many times to promote it to increase branches and budding. After shedding the flowers, cut off the residual flowers at the right time, cut off the too dense and thin branches, so as not to consume too much nutrients, but it is cold in winter and should not be re-cut.
