Planting methods of Pelargonium (experience): detailed introduction of planting methods of Pelargoni

There are many articles about Geranium cultivation on the Internet. Xiaobian always thinks that no matter how good the theory is, it's not as practical as experience! Therefore, Xiaobian specially looked for this article. This article is the experience accumulated by Huayou in maintaining geranium in the past four years. I hope it can be helpful to Huayou for your reference.

Planting methods of geranium (experience) planting methods of Geranium: 1. Soil: Geranium likes the soil with good air permeability. If conditions permit, it is best to use peat soil to plant or at least mix some peat in the soil. The soil is slightly acidic, and pH value is between 5.5-6, which is most suitable for the growth of Geranium. Generally, it should not be higher than 7, otherwise, it will affect the absorption of trace elements and the stability of the soil Salt should not be too heavy. Before planting, wash the soil with clean water.

After planting Pelargonium, wash the soil with large amount of water, so that the soil can be completely integrated with the root tip. It is not easy to stay seedlings, and new roots can grow out more easily. As for the foliar spray, one or two times is enough. If the temperature is too low and the weather is windy in the north, it can be surrounded by some wind barriers if conditions permit. If the sun is very strong, it should be properly shaded after planting for three to four days, It doesn't matter after four days, no matter how big the sun is.

2. Watering: watering is a big problem! After planting, the water is usually poured once two days later. It is very important to keep the soil moist for the first two weeks, but it can not be watered too much. In this way, the soil is easy to harden, the air permeability is poor, and the roots are easy to rot with too much water, especially in low temperature weather, Take the dry wet interval method, that is to say, after pouring water and fertilizer once, the interval time should be a little longer, so that the soil becomes dry before watering. The advantage is that the air permeability is good, dry soil can stimulate the growth of root system, if the soil is too wet for a long time, the root system will not grow well!

3. Fertilizer and water: Pelargonium planting a week without fertilizer, a week later you can give light fertilizer on the line, if you can measure out the EC Value of 1.0-1.2 is the best. It can be increased to 2.0 after the third week, and the maximum should not exceed 2.5.

4. Pinching: when the new leaves grow out, they can be pinched when there are 6-7 leaves (four or five vine leaves can be pinched). At least one leaf should be removed for pinching. Don't just pick some snacks. The top advantage is still not removed. Don't be reluctant to do so. Most geraniums have a bud for every two neutrons. Don't be reluctant to pick it at the beginning Long flowers, it is not easy to grow up, especially the vine varieties, flowers should be removed as soon as they come out, this is very important.

Pelargonium planting Pelargonium six major issues: 1, pot soil selection issues:

The best soil is peat. If not, you can also use Yekang, vermiculite, perlite, as well as the so-called nutrient soil on the market. It can also be mixed with many kinds of soil, but generally it doesn't use soil, because it is easy to harden. For the selection of pots, five flowers and eight doors can be used. For the ordinary 15 cm pot, the author recommends two plants, so that it is easy to plump and can flower ahead of time, such as the pot over 20cm, Three strains are suggested.

2. Water control issues:

After a week of planting, the seedlings are no longer watered from the leaves. It is most suitable to keep the soil moist but not waterlogged. The soil should be dried properly once a week, so that the root system is not easy to turn yellow and grow stronger.

3. Soil pH problem:

Generally, the pH value of peat soil, nutrient soil and horticultural soil is 6.5-7.5, which belongs to neutral soil, while the most suitable pH value of Pelargonium is 5.5-6.0. Conditional flower friends, can add some citric acid to adjust the soil pH, so that the growth rate of the flower is certainly stronger than that without adjustment, and because iron, magnesium and other nutrients are easier to absorb at low pH, so the seedlings will be more healthy.

Six problems in growing Geranium

4. Topping problem:

Generally, when a Pelargonium has five to six effective leaves, it should be toppled when it is growing vigorously. One leaf and one core should be removed, leaving four to five large leaves. After topping, strengthen fertilizer and water management, generally can grow 3-4 strong lateral branches, a pot of 15 cm flowers. If two plants are planted, 6-8 lateral branches can be obtained after the first topping. If you are a anxious guy, you can even let it start to grow flowers. However, Xiaobian suggests that it is better to carry out the second topping, that is, when the lateral branches grow three to four leaves, then remove the core. After the second topping, you will get a full plant type. At this time, strengthen the fertilizer and water, and within a month, you will get a satisfactory harvest.

5. Pest problems:

Gray mold easily occurs at night when the temperature is lower than 18 degrees, so generally speaking, there is no disease in Pelargonium in summer. On the contrary, gray mold is most likely to occur in cold weather in winter. The solution is to irrigate the soil with chlorothalonil every month, which can greatly reduce the occurrence of diseases. As for insect damage, generally it will not happen, but we should also pay attention to observation, especially on the back of leaves. If we find small animals such as red spider and thrips, don't be soft handed and kill them!

6. Summer problems:

Geranium does not like high temperature, if the temperature is too high, such as summer in Shanghai. When the night temperature exceeds 26 ℃, the new leaves of most varieties of Pelargonium will turn yellow, and some creeping Pelargonium even turn white. At this time, the growth of Pelargonium basically stops. The main reason is that the leaves of Pelargonium will turn yellow because of its vigorous breathing and excessive nutrient consumption at night, so we can only take appropriate shading in summer, and it can't be accumulated in the afternoon After that, pour some fertilizer and water properly, and the new leaves will turn green in September!
