How to raise geranium geranium breeding methods and precautions

Geraniums, I believe many people have heard or seen, geraniums like the sun, especially in autumn, in order to give geraniums a good light, most people will choose to grow geraniums on the balcony, in addition to light is very important to geraniums, what other factors can affect the cultivation of geraniums? Let's introduce it to the editor.

How to raise geraniums

1, temperature control: the most suitable temperature for geraniums is 10 Murray 20 degrees Celsius, that is, spring and autumn is the most suitable, too cold in winter and too hot in summer. So in the summer, we must prevent the sun exposure, sunscreen is certainly useless, put it in a cool place. In winter, the indoor temperature should not be lower than 0 °, otherwise it will be frostbitten. If there is no warm equipment, turning on a 200 °light bulb in a small room also has a certain anti-freezing effect.

2. Moisture control: geraniums are taboo to be overwatered. If you find that the roots of geraniums fester, it is probably due to overwatering and muggy weather. The frequency of watering should be controlled by watering once every three or two days. Every time you need a large amount of water, you can only water it thoroughly.

3. The choice of soil: geranium is suitable to survive in sandy soil, and the effect of mixing some sandy soil in the flower market will be better.

4. Pay attention to the prevention and control of insect pests: leaf spot and Fusarium wilt are easy to grow in geranium. if the leaf edge is withered and yellow, you should consult a professional florist and do not dispose of it at will.

5. Prevent the influence of bad weather: the windy weather will blow the geranium, while the heavy rain will make the root system of the geranium soaked by Rain Water, causing the root to breathe anoxia and fester. So, in order to raise geraniums, you have to pay attention to the weather forecast.

6. Control of fertilization: excessive fertilization at one time will cause dehydration of geraniums, but the author cannot tell you how much fertilizer is appropriate, because it has something to do with the quality of your soil, the size of flowerpots and the size of geraniums. You'd better ask the shop owner the amount and frequency of fertilization when you buy flowers. If you apply too much fertilizer, such as too much nitrogen fertilizer, it will cause the plant to grow and not blossom. In this way, the value of your geranium is low. Excessive fertilization and logistical watering can relieve symptoms.

7. Plenty of sunshine: plenty of sunshine helps geraniums blossom, but if the temperature is too high, it is not suitable for direct sunlight. You have to control the degree of sunshine in spring and autumn, and in summer, pay attention to not basking in it if the temperature is too high.

Culture methods and matters needing attention of geranium

I. Culture methods of geraniums

1. Choose containers, choose different containers in different seasons, be sure not to be too big. Take the seedling plate as an example, using 50 holes in summer is more suitable for 72 holes in spring and autumn, and 128 holes in winter (see figure). The most important point is that you must disinfect. The best disinfection method is very simple. After rinsing the container with clean water, put it in the sun for three days, and avoid being caught in the rain. Flower friends can also choose other containers to soak with disinfectant at home.

2. There are many kinds of cutting substrates. I use the simplest and cheapest, peat soil. I personally suggest that everyone use imported peat. I use domestic mud in order to save costs. Peat soil is put into a container to compact. Remember to compact the air out of the soil! In this way, the roots coming out in small days will be very strong and the survival rate will be very high, followed by the disinfection of the matrix, which is generally treated with carbendazim meltwater and methyl topiramate in summer.

3, cutting seedlings, I see many people use some old branches to do cuttings, you may think that this kind of branches are relatively sturdy and the survival rate is relatively high, but I think it is not very ideal, and the old branches have almost no advantages. I generally use tender wood cuttings (see figure, remove buds), tender branches have several advantages, strong vitality, top advantage, good nutrient is relatively rich.

4. the slow seedling period is short, but the old branches not only take root slowly, but also are easy to rot with miscellaneous bacteria. Take root quickly, the cutting cycle can be reduced by about a week.

5. Save area, cuttings can be managed in batches for many times, small branches can reduce watering times, and ventilation is ideal to reduce pathological changes due to poor ventilation. (3) it grows rapidly after survival, and the plant type can be easily controlled.

II. Matters needing attention of geranium

There are different varieties of pelargonium and different plant height. Small plants should be selected for family planting. In addition, growth agents are needed to regulate them. When the plant grows to 12 cm or 15 cm, spray chlorpromazine once a week for 2 consecutive times. Ensure that the light is 14-18 hours a day, which can effectively control the height of the geranium and provide high-quality potted flowers. Special attention should be paid to watering geraniums, saying that more plants will die, while the roots will rot easily if the temperature and humidity are high. Of course, the flowering time can also be controlled, and the full flowering period is generally from April to June, but if the temperature is raised appropriately in winter, it can blossom all the time from September in autumn to June of the following year.

Pruning methods of geraniums

The main results are as follows: 1. According to the growth of the plant, we choose to leave 3-5 main branches with strong growth and uniform distribution near the base after autumn, which are too dense for others. Slender and overgrown branches can be cut directly from the base.

2. Then the main branches and side branches are cut short, and only the strong lateral buds are retained in each side branch. In this way, the distribution of the whole branch is uniform and compact, and the plant type is plump and sturdy.

How to propagate geraniums

1. Sowing and reproduction: after the seeds are collected, you can sow the seeds. If you want to sow the seeds when the weather is cool, you can first dry and store the seeds. When the temperature is 20 ℃, they will germinate in about 7-10 days.

2. Cutting propagation: it is best to cut in spring and autumn, choose healthy cuttings, then dry them with indolebutyric acid for about 5 seconds, wait until it wilts and then cut, pour water to avoid being exposed to strong light, and take root after 2-3 weeks.

As can be seen from the above, geranium is a kind of tenacious plant, and it can also show a tenacious side in the case of low temperature, but in the editor, I would like to remind you that the cutting link of geranium will be a little difficult, but there is no problem to grasp the time and light.
