1, pruning branches and leaves. In the process of tomato growth, if yellow and dry branches and leaves are found, they need to be pruned in time to reduce nutrient consumption. When pruning, the yellow branches and leaves can be cut off from the base. Timely pruning can also improve internal ventilation and light transmittance, which is very beneficial to overall growth.

2, the top. When tomatoes grow to 50-60 cm high, they should be topped in time to control the height. The topping method is very simple, just remove the growing point at the top, and pay attention to leaving 2-3 leaves in the top ear. Topping in time can not only control its height, but also make nutrients more concentrated, which is more conducive to later flowering and fruiting.

3. Fight in time. It is inevitable that tomatoes will grow branches in the process of growth, and they need to be cut off in time. These branches not only can't blossom and bear fruit normally, but also consume a lot of nutrients and affect the growth of fruits. Pay attention to the crotch must be done in sunny days, otherwise the wound is easy to be infected.

4. Trim. The most commonly used pruning method of tomato is single stem pruning, that is, leaving a trunk on the tomato and cutting off other side branches. This method is suitable for close planting and early maturing tomato varieties. You can also use the double trunk pruning method. In addition to leaving a trunk, you can also choose another side branch as the second trunk, so that the trunk will blossom and bear fruit better.
