Sowing method of geranium

In January and April, buy seeds from the market and try to choose varieties with good quality, easy to germinate and blossom, and good maintenance. Sow the seeds directly in the flowerpot. Wet the soil before sowing. Then cover the flowerpot with a shading cloth so as not to see the light.

2, 2-3 days later, lift the lid, you can see that the seed has been exposed white, at this time sprinkle a little soil on the seed.

3. In another 2-3 days, small leaves will basically grow. Congratulations on your successful sowing. The rest of the time is to wait for the seedlings to grow up slowly, and when they reach 3-4 leaves, they can be replanted in pots.

After introducing the sowing method of geranium, let's take a look at the psychological and physiological effects of geranium.

Cultivation method of geranium and planting method of Huayu geranium

Geranium likes warm climate and fertile loose soil, is resistant to drought and waterlogging, grows poorly in hot summer and high temperature, and is in a semi-dormant state. Geraniums have strong adaptability, bright colors and long flowering period, so they are very popular with people. the following is the experience of sorting out the daily cultivation of geraniums and flower friends, hoping to provide some reference for flower friends.

Geranium culture methods (daily culture methods) 1. Soil selection

The geranium is also adaptable and can grow in all kinds of soil, but the sandy loam soil rich in humus grows best.

2. Watering control

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 the plant to grow too much, the position of the flower branch to move up, and the leaves to yellowing and fall off.

3. Plenty of sunshine

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 dysplasia of inflorescences. Buds in low light often fail to bloom and wither ahead of time.

4. Temperature control

The geranium likes to be warm in winter and cool in summer. It can blossom normally when the indoor temperature is kept at 15 ℃ every day in winter and the night temperature 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. Pest control

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 and coring in order to promote more flowering of the more branched geranium, it is necessary to pick the heart of the plant many times to promote it to increase branching and bud pregnancy. 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 method of geranium (experience sharing among flower friends)

1, after the beginning of spring, we must raise the roots of geraniums, there is no strong root system, the rest are floating clouds. Geraniums must be fully fertilized. I use garden soil and earthworm fertilizer to make basin bottom soil, and peat and perlite on top. At that time, I bought 20 packs and 5 yuan free delivery) to add slow-release fertilizer. Usually also alternately use Bizhuang and chlorophyllin to irrigate the root. I usually prune in autumn and put bottom fertilizer when I change the basin. I feel good. The sky grows strong, such as Red Bowl, King, Mr. Ren, UU Bowl, UA Bowl and so on. They grow like small trees to take up space.

2. After March, we will water some fertilizer to promote the flowers. In view of the bad weather for the summer, the Tianmiao bought will die without seeing the flowers. Instead of hanging, we should let it show its elegant demeanor. So I have had a good flowering this year, and now it's late July, and some days are still brilliant, which is why I like geraniums. I mainly use must blossom, its effect is very good, but also a small amount of flowers blossoming 28 and so on.

3. Autumn geraniums must be strongly cut, which can effectively control the column shape and promote more new buds. At the end of September of the previous two years, I began to cut, change pots and add base fertilizer, cutting, and the effect was very bad. The survival rate of cutting was very low, and a lot of branches were wasted. According to our weather conditions, strong cutting began in mid-late October, and the effect of changing pots with base fertilizer and cutting was better. This is what I plan to do this year.

4. Last year, a lot of geraniums were bitten to death by worms. I learned a lesson. This year, I use the god of protecting flowers to irrigate the roots.

5. In the growing period of geraniums, we should pay attention to thinning leaves and dispose of yellow leaves, old leaves and residual flowers in time. Geraniums should be ventilated and ventilated. After the rainy days, I will use the god to protect the flowers to irrigate the roots to minimize the damage caused by germs to the day.

6. Watering is also the key to raising geraniums. In the past, it was watered regardless of whether it was watered, basically every two days. Nowadays, I have also heard more about the experience of watching flower friends raising the sky, combined with their own geographical location, weather conditions, especially the characteristics of each day, depending on the situation. For those days when the roots are well developed and in full bloom, they should be watered frequently and thoroughly. While some root systems are generally developed, slow-growing days are a different matter. I reserve my opinion that the geranium should be thoroughly dry and watered. There is a red Pandora is dry, the result hurt the root system, but also found in time, cut off the branches, has recovered.

How to grow geraniums? Planting methods and management of geraniums

Geranium, alias Hydrangea, native to 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.

Geranium is a potted flower with good ornamental effect, and its cultivation and management should pay attention to the following points:

1. The matrix uses excellent substrates as much as possible, such as 55% to 70% peat, 20% to 25% perlite, 5% to 10% vermiculite and 5% to 10% ceramsite. It is ideal to mix according to this ratio. Because geraniums can be divided into hanging and erect varieties, there will be some differences in cultivation and management. For example, the pH value of fishing series is between 5.5 and 5.8, and the pH value of common species is between 6.0 and 6.3. The cultivation substrate should be determined before planting and every other week after cultivation. If you need to adjust the pH value, you can use acidic or alkaline fertilizer.

2. Water and fertilizer management can soak the substrate with 400 mg / kg nitrogen fertilizer solution before cultivation, which can promote the rapid growth of plants after planting. Can also be combined with the first irrigation for fertilization, the concentration of nitrogen is 300 mg / kg, watering is best in the early morning, can be carried out when the soil is slightly dry. But it should be noted that excessive drying can cause yellow leaves.

3. From 4 to 6 weeks after planting, the ideal temperature is about 21 ℃. This temperature can promote plant rooting, accelerate growth and branch extension.

4. Light geranium belongs to long sunshine flowers, and its growth is related to flowering and light accumulation. The more light exposure, the greater the growth, the earlier the flowering. Within two weeks after planting, the light intensity should be maintained at 27000 to 32000 lux, and then gradually increased to 38000 to 49000 lux.

5. Botrytis cinerea and true mildew are the main diseases of geranium. first of all, we should do a good job of prevention, keep the plant growth environment well ventilated, clean up the withered branches and leaves in time, keep a high night temperature indoors, and arrange irrigation in the early morning as far as possible. Mycosis can reduce the incidence of mycosis by using coarse peat matrix and not making plants short of water.

Hanging geranium is prone to edema disease, which is easy to occur when the plant absorbs a large amount of water and cannot evaporate through the leaf surface in time. The occurrence of the disease can be prevented by some methods, such as ensuring that the plant will not be short of water and drying when the temperature is high, ensuring that the air is fully ventilated and the relative humidity is less than 75%, shading treatment to avoid sudden strong light exposure, regular supplement of calcium nitrate fertilizer and so on.

The main pest of geranium is thrips, and many chemicals can control thrips.
