What is the best fertilizer for tomatoes?

Tomato fertilization time

After the tomato inflorescence sets fruit, start applying quick-acting fertilizer 1-2 times to ensure that the plant does not lack fertilizer. When the young fruit is rapidly expanding, fertilizer must be applied frequently. Basically, before the tomatoes overwinter, the principle of fertilizing is to apply fertilizer once every two waterings.

What fertilizer to use for tomatoes

Organic fertilizer, biological fertilizer, potassium sulfate compound fertilizer are the best base fertilizer for tomatoes. Generally, no fertilizer is applied during the flowering period. Potassium dihydrogen phosphate plus amino acid calcium foliar fertilizer is sprayed on the leaves. Balanced water-soluble fertilizer is applied in the early stage of fruit setting, and high-potassium water-soluble fertilizer is applied in the fruit expansion period. Calcium fertilizer is supplemented in time, and sugar alcohol calcium is sprayed on the leaves to promote fruit expansion.

Tomato fertilization method

Before transplanting tomato seedlings, high-quality farmyard manure, urea, ammonium phosphate, and superphosphate can be applied. Urea solution, potassium dihydrogen phosphate solution, and Hexin liquid fertilizer are commonly used during the seedling growth period. Ammonium nitrate and superphosphate are used during the fruiting period. Potassium dihydrogen phosphate, superphosphate and other fertilizers can be sprayed during the peak fruit-bearing period.

Tomato fertilization precautions

From planting to fruit setting, topdressing should be done according to the seedlings. If the topdressing is too much and too concentrated, it will easily cause the plants to grow too tall, and even cause the flowers and fruits to fall off. Avoid fertilizing when the soil is wet and the temperature is high at noon, as this will easily cause fertilizer damage.
