What are the culture methods of geranium?

In our life, geranium is a widely planted flower plant with colorful flowers and long flowering period. potted plants are used in home beautification and embellishment, and it is also one of the flower varieties that many people choose to decorate at home. So, what are the breeding methods of geraniums? Let's take a look.

I. brief introduction of geraniums

Geranium, also known as hydrangea, red, red, sunset red, sunflower, mosquito repellent, butterfly, etc., originated in South Africa, is a perennial herbaceous flower. The leaf has a long handle, the leaf margin is serrated, and the leaf surface has deep annular markings. Corolla usually 5-merous, inflorescences umbellate, growing at tip of straight pedicel. Because the flowers are as dense as balls, it is also known as hydrangea. The colors of red, white, pink and purple vary a lot. The florescence begins in early winter and lasts until the beginning of summer. Potted plants should be used for indoor and outdoor decoration; they can also be used as flowers in spring flower beds.

Like warm, moist and sunny environment. Poor cold resistance, afraid of dampness and high temperature. The suitable temperature for growth is 13: 19 ℃ from March to September, and 10: 12 ℃ in winter. It is semi-dormant from June to July, so watering should be strictly controlled. Suitable for fertile, loose and well-drained sandy loam. The winter temperature is not lower than 10 ℃ and can withstand 5 ℃ low temperature in a short time. Single petal varieties need artificial pollination in order to improve the seed setting rate. The seeds matured about 40-50 days after anthesis.

The geranium likes to be warm in winter and cool in summer. It can blossom normally when the indoor temperature is kept at I015C every day in winter and the night temperature is above 8 ℃. But the optimum temperature is 15-20 ℃. Geraniums like dryness and hate dampness, and should not be watered too much in winter. See dry and wet. 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. Geraniums need plenty of sunlight for a long time, 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. 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) every 1-2 weeks with 800-fold potassium dihydrogen phosphate solution every 7-10 days can promote normal flowering.

How to raise geraniums

1. Living environment

Geraniums have high requirements for light and temperature, and generally the best temperature for the growth of geraniums is between 10 and 20 degrees Celsius, that is, it is very suitable for the growth of geraniums in spring and autumn, too hot in summer and too cold in winter will make geraniums go dormant, so be careful not to expose geraniums in summer and winter. Do not put it in a place below 0 degrees Celsius, it will hurt it. In addition, it is necessary to prevent the effects of bad weather on the geranium. if the heavy rain soaks the geranium, it will make it difficult to breathe and rot at the root of the geranium.

2. Moisture

Geranium originated in southern Africa, is a plant that does not like much water, so do not overwater the geranium in the breeding process, if too much watering will lead to the root rot of the geranium, if it grows in this watery environment for a long time, it will affect its growth and lead to death, so it only takes two or three days to water it once, but each time it should be enough.

3. Fertilization

4. Temperature

Geraniums like a warm, humid and sunny environment, and the most suitable temperature for growth is between 10 and 20 degrees, that is, the temperature in spring and autumn, so measures should be taken to protect it in winter and summer. it is necessary to put it in an environment where the temperature is not lower than zero in order to avoid frostbite, and in hot summer, move it to a cool place to avoid exposure in the hot sun.

5. Pest control

For geraniums, the two common diseases are leaf spot and Fusarium wilt. The general prevention and treatment of these two diseases is to place geraniums in a ventilated and transparent place to prevent the branches from being too dense. Remove the diseased leaves in time so as not to infect other leaves. It is also important to note that too much fertilization can also make geraniums sick.

6. Pruning

The growth environment of geraniums requires fertile soil, which makes the growth of garden geraniums very fast. Geranium as an appreciative plant, it is usually carefully maintained and trimmed, usually trimmed three times a year. The first time is mainly to sparse the branches, the second is to cut off the withered flowers and overdense branches, and the third is to rest and repair as a whole, that is, plastic surgery.
