What are the cultivation methods of geranium flowers, do you know?

1.Soil: Geraniums are also highly adaptable and can grow in a variety of soil qualities, but humus-rich sandy loam soils grow best.

2.Watering: Geraniums like dryness and dampness, and should not be watered too much in winter.

If the soil is wet, the stem is soft and tender, which is not conducive to the germination and opening of flower branches; Long-term excessive humidity will cause the plant to grow, the flower branch parts will move upward, and the leaves will turn yellow and fall off.

The growth temperature of geranium flowers needs to be between 15 and 25 degrees, and the root system of sunflowers is not very developed, so it is necessary to loosen the temperature of the soil from time to time, and also need a dry environment to maintain a certain humidity, and can not lack water for a long time.

Summary Water control: Do not water too much, usually once every 2-3 days, and pay attention to rain. Adjust the temperature:

The most suitable temperature is around 10-20, and it needs to be adjusted within the appropriate range in summer and winter. Light requirements: to see more sunlight, not to be raised in the shade for a long time, easy not to bloom.

Prevention and control of pests and diseases: usually open more windows and separate diseased plants, and use medicine as soon as possible after the onset of the disease.

1. Soil: Use loose and permeable soil.

2. Watering: Watering should be appropriate, sufficient water should be maintained during the peak growth period, and the potting soil should be in a moist state.

3. Temperature: 15-25 suitable for growth.

4. Qingzi light: you need to receive sufficient sunlight, and when the sun is too strong, you should take shade measures.

1. Soil. To use loose and well-permeable soil, the culture soil can be mixed with humus, peat, perlite, and organic fertilizer, and it is best to turn over the pot once in autumn.

2. Watering. Watering should be appropriate, in spring and autumn is its peak growth period, at this time to maintain sufficient water, potting soil should be in a moist state, but do not produce stagnant water; Reduce the amount of watering when the temperature is low; If there are many drainage measures in the rainy season, it should be placed in a dry and ventilated place to avoid root rot caused by stagnant water; In winter, the indoor temperature is relatively low, so it is necessary to water less.

3. Temperature. The temperature suitable for the growth of geraniums is 15-25, and the indoor temperature in winter is best controlled at about 10, not lower than 3. The maximum temperature should not and should not exceed 35, once it is in a high temperature environment, it will enter a semi-dormant state.

Keep it in a ventilated environment as much as possible to avoid stuffy breeding environments.

4. Illumination. Geraniums need to receive sufficient sunlight, but in the summer when the sun is too strong to take shade measures, other seasons can receive sunlight, if the light is insufficient, it will not bloom, when flowering to avoid direct sunlight, you can move to the indoor appearance, and wait for the flowers to be put back in a sunny place. Rotate the pot as much as possible to make the foliage receive more even light.

1. Soil: Geranium has strong adaptability, and all kinds of soil can grow, but the sandy loam soil rich in humus grows best, and the soil bought in the flower market will be better mixed with some sandy soil. Geraniums grow quickly and need to be repotted once a year, and in early spring, the old roots and old soil are removed when repotting, and moved outdoors to a sunny place in late April for maintenance.

2. Temperature: Geraniums like a warm, moist and sunny environment, the most suitable temperature for growth is between ten and twenty degrees, that is, the temperature in spring and autumn, so it should be protected in winter and summer, if it is winter, it should be put in an environment where the temperature is not lower than zero degrees, in order to avoid frostbite, and in the hot summer, it should be moved to a cool place to avoid exposure to the scorching sun.

3. Water: Geranium is a plant that does not like more water, so in the breeding process do not water too much water for geraniums, if too much watering will lead to the root rot of geraniums, if it grows in this watery environment for a long time, it will affect its growth and cause death, so when breeding geraniums, you only need to water it once in two to three days, but the amount of watering should be enough each time.

4. Fertilization: Too much one-time fertilization of geraniums will cause dehydration, and too much fertilization can be used to alleviate symptoms by logistical watering. But if it is not fertilized for a long time, it will also cause it to have insufficient nutrients, and the amount of geranium fertilizer is directly related to its soil quality, flower size and pot size.

5. Light: Geranium needs plenty of sunlight during the growing season, so it must be placed in a sunny place in winter. Lack of light, long stems and leaves, thin and soft peduncles, and poor inflorescence development.

Flower buds in low light tend to bloom poorly and wilt early. Plenty of sunlight helps geraniums bloom, so get more sunlight in spring and autumn, and pay attention to the temperature in summer, if the temperature is too high, you should avoid exposing geraniums to light.

6. Pests: Geraniums have poor ventilation and are too humid, and are prone to leaf spot and flower wilt. After discovery, attention should be paid to ventilation, immediately remove the sick flowers and leaves to prevent infection, and spray the same amount of Bordeaux liquid for control.

The main insect pests are red spiders and whiteflies that damage leaves and flower branches, which can be sprayed with 1000 times of 40% dimethoate emulsion.

1. Geranium soil can choose 4 parts of humus soil, 3 parts of garden soil (or peat), 2 parts of river sand (or perlite), 1 part of organic fertilizer mixed culture soil, or fine sandy soil, humus soil, perlite and organic fertilizer mixture. Geraniums require loose and breathable soil, which can be repotted in autumn every year, or loosened in time.

2. Fertilization method. During the growth period of geraniums, liquid fertilizer was applied once every 10 15 days, and in the spring and autumn seasons of the vigorous period, liquid fertilizer was applied once every 7 10 days. Nitrogen fertilizer is the main fertilizer before the bud, and phosphorus and potassium fertilizer are the main fertilizer after the bud, and the concentration is appropriate. In winter, it is kept indoors, the temperature is high, and it will not stop growing, and it can be fertilized appropriately.

In the summer heat, the plant is in a semi-dormant state, and fertilization should be stopped. It is best to fertilize in the evening and water the next morning.

3. Watering method. Geraniums should be watered properly, rather dry than wet. In the spring and autumn growing season, sufficient water should be satisfied, so that the potting soil is often kept moist, but not waterlogged; On cloudy or rainy days, generally do not water and do not fertilize.

Plants can be properly receptive to rainwater, but avoid excessive rainwatering. Otherwise, it is easy to cause root rot. In winter, according to the indoor temperature, try to water with temperature, so as not to let the water temperature be too low, resulting in yellowing of the stems and leaves of the plant.

4. Temperature requirements. Geraniums like warmth, avoid high temperatures, and are afraid of cold. The suitable growth temperature of geraniums is 15 25, and the temperature of 10 should be maintained indoors in winter, and below 3 is susceptible to cold damage, but some varieties can tolerate low temperatures of 0.

In summer, when the temperature exceeds 35, it enters a semi-dormant state. Try to keep it ventilated and avoid a stuffy environment that is not conducive to sleep.

5. Light requirements. Geraniums are not afraid of bright light, but need shade at noon in summer. Geraniums grow vigorously in the sun, with dark green leaves, short internodes, and beautiful plant shape.

When home farming, autumn, winter and spring should be placed in a place with direct sunlight, and when flowering, it can be moved indoors to enjoy and maintain, and properly receive light, but it is necessary to avoid strong direct light, so as not to cause petals to scorch.

6. Precautions. There are different varieties of geraniums, and the plant height is also different, so small plants should be selected for home planting, in addition to this, the adjustment of growth agents is also required. When the plant grows to 12 cm or 15 cm, spray chlormequat 1 time a week for 2 consecutive times.

Ensure 14-18 hours of light per day, which can effectively control the height of geraniums and provide high-quality potted plants. Geranium watering should be paid special attention, saying that it will cause plant death, and the roots are easy to rot if it is high temperature and humidity. Of course, the flowering time can also be controlled, the peak flowering period is generally from April to June, but the temperature is appropriately raised in winter, and the flowering can be maintained from September to June of the following year.
