How to grow and manage tomatoes: what kind of fertilizer is used to grow tomatoes? How to fertilize tomatoes

Do you know how to grow tomatoes? How to grow tomatoes and how to manage them? If you want to grow tomatoes, you can take a good look, the following is accepted, in growing vegetables, fertilization is very important, then how to fertilize tomatoes? Let's take a look at it together.

Growing tomatoes is one of the most satisfying experiences, because small plants quickly achieve results, red fruits make people happy, and the fruits that have just been picked from the plants are so sweet that they are not comparable to those bought. But tomatoes are often infected with germs, and if they can be prevented in advance, they can be foolproof.

So experienced horticulturists or farmers will have some treasures around them, enough to do a good job of prevention. One of the treasures is copper sulfate Copper Sulfate. When copper sulfate is mixed with water, a disinfectant is released, which is used when tomatoes are first grown to prevent diseases later in the season.

There are many copper-containing potions in the store copper fungicide, but the brand name may be different, some are called Copper Spray, or Copper Dust. Look at the ingredients in the instructions when you buy them. The more MCE (metallic copper equivalent) they contain, the more effective they are. It is best to spray tomatoes when they are young (that is, within two to four weeks after planting young plants) to avoid getting sick. Usually once, at most two times (seven to ten days apart) is enough to achieve the effect. Because tomatoes are prone to mold blight, there are two types of mold, early blight and late blight, so they can be sprayed every two weeks to make sure they are disease-free.

Fertilizer: tomatoes need a lot of fertilizer, especially calcium. If the calcium deficiency is serious, the fruit is difficult to form, and even if it is formed, it will blacken and rot halfway from the base. Someone planted Tums, a Western medicine for stomachache, into the soil next to the tomato. Because Tums is high in calcium, even when taken as a calcium tablet. And Tums is very soluble in water. Another friend dried egg shells and shrimp shells, ground them up and buried them in the soil. Many other people will use lime supplements. Gardening shops sell packaged Garden Lime (or Agricultural Lime, limestone powder) as supplementary fertilizer, which is good for plants such as tomatoes, eggplants and chili peppers. However, the amount of time to be used should follow the instructions, otherwise the soil will be too alkaline. From time to time, some people plant banana peels next to tomatoes and rose plants because bananas contain high potassium. It's all what plants need.

The most frequently asked question about tomatoes is, although there are many flowers, why are there no tomatoes? In addition to the calcium deficiency mentioned above, one possible reason is that there is no bee pollination. If so, you must pollinate manually. The way is to buy cheap watercolor pens, or small brushes, gently wipe between each flower, so that the male and female pollen will mate, there will be fruit. The brush should be clean and don't use it repeatedly.)

To keep the soil moist, you can use more mulch, that is, lay a layer of soil on the soil surface, buy mulch, or find your own pine needles, bark shavings and so on. Or use ordinary compost soil. It is best to cover the soil after watering. When growing tomatoes, you must water them regularly. If the roots are short of water, the flowers may wither and fall. If there is a lack of water after the fruit, the fruit will be tasteless (lack of sugar) and even fall seriously. Others asked why the fruits or flowers of tomatoes fell. You can find the reason below:

A sudden rise or drop in temperature (too big temperature difference between day and night); insufficient or too high humidity; too much nitrogen fertilizer (or not enough nitrogen fertilizer); no bee pollination; lack of water; diseases and insect pests; too much fruit. In addition, the soil where tomatoes grow can sometimes grow germs of their own, so if one year your tomatoes suddenly stop growing fruit, they may not regenerate next year, so you have to stop growing tomatoes or even plants of the same family, including potatoes and eggplants. At the same time, avoid planting the same kind of plants in the same place every year.
