If you want to grow tomatoes at home, you must first understand the growth habits of tomatoes, and then fully understand them from sowing and seedling raising to pruning and fruit setting, and then to water and fertilizer management and pest control. Let me make a brief introduction, because I just got three small tomato seeds today and am going to plant them.

The growth habit of small tomatoes involves balcony tomato planting, so I only introduce the related content of balcony planting.

First, tomatoes are deep-rooted crops, so we must choose deeper flowerpots in the choice of flowerpots. Moreover, small tomatoes now generally belong to infinite growth type, so in the depth and width of flowerpots,

Try to be the biggest. You can find some used barrels to grow tomatoes, but they are ugly.

Secondly, tomatoes belong to climbing crops, so they should be put on shelves when cultivated, especially small tomatoes, which belong to infinite growth type, so they should be put on shelves, so we should decide how many plants to plant according to our own space.

Third, tomatoes like fertilizer and water. When planting, especially on the balcony, substrate should be used directly instead of garden soil, so as to better grasp the management of fertilizer and water. As for fertilizer and water management, I will introduce it separately below.

Fourthly, tomato is a kind of crop that grows lateral branches easily. In the process of cultivation, the lateral branches must be cleaned frequently. I will introduce how to clean them separately.

Fifth, tomatoes like light. If the balcony illumination time is short, it is recommended not to plant it.

Let me introduce the method of planting tomatoes on the balcony from the beginning of seedling raising.

The seedling stage of small tomatoes is very long, but now the temperature is higher and the seedling stage will be shorter. Prepare several paper cups filled with substrates. The substrate is purchased from the flower and bird market. General 15 liter substrate is less than 20 yuan. After watering, put tomato seeds on the substrate, sprinkle a layer of substrate, cover with a thin plastic bag and wait for germination. Wait until the tomatoes grow 5-6 leaves, and then plant them in flowerpots.

It is suggested that substrate cultivation be used for water and fertilizer management because there are few nutrients in the substrate, and we can make up for the lack of fertilizer by topdressing. If soil cultivation is adopted, tomatoes will grow badly because of poor control of fertilizer dosage.

After planting for about 7 days, the plant has survived. From this time on, the fertilizer should be watered once a week. Before flowering, it is also better for foliage plants to use a water-soluble fertilizer with a balance of nitrogen, phosphorus and potassium. After flowering and fruit setting, high phosphorus and potassium fertilizers are poured once a week. These fertilizers can be bought in agricultural stores. If you don't understand, I recommend the ratio directly, and you can buy it at the agricultural store according to this ratio. The equilibrium ratio is 15: 15: 15, and the ratio of high phosphorus and potassium fertilizer is 10:20:30 or10: 40. People in agricultural stores will recommend the corresponding fertilizer to you when they hear your quotation, and usually buy it. When applied, it is generally diluted by more than 500 times, that is, 1g fertilizer is mixed with more than 500g water.
