Matters needing attention in how to cultivate geranium

Geraniums not only have strong ornamental value, but many owners like them, but if you want to raise geraniums well, you should see how to cultivate geraniums and the matters needing attention.

Culture methods of geraniums

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 plants to grow too long, flower branches 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 and poor inflorescence; buds in low light often bloom poorly 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 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 7-10 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.

Culture methods of geraniums-matters needing attention

The main results are as follows: 1. in order to control the plant height and achieve the purpose of large and colorful flowers, in addition to selecting dwarf geranium varieties, the application of growth regulators is very important. On the same day, the geraniums were planted in 12 or 15 rice pots for 2 weeks, and the leaves could be sprayed with 0.15% dwarf or longer spraying, once a week, twice in a row, with light for 14 hours a day. This can effectively control the height of the geraniums and provide high quality commercial potted flowers.

2. it is more resistant to dryness and is afraid of moisture. Too much water is easy to cause plant death, and if high temperature and humidity is high, the root is easy to rot. Soil with good drainage, loose and rich in organic matter is required. The flowering period is long, and the full flowering period is from April to June. If the higher temperature is given in winter and properly managed, it can continue to bloom from September in autumn to June of the following year.
