What should be noted when growing overwintering tomatoes? Please advise
The growing period of overwintering tomatoes falls in the high-temperature season, with the prevalence of diseases such as viral disease, stem base rot, and phytophthora fruit rot, outbreaks of pests such as aphids, whiteflies, and mites, and the effects of high temperature, strong light, and dry conditions. Zhongdiwang has compiled the two points to note for overwintering tomatoes, listed below for netizens to refer to.
Point one,Flat-bed cultivation not only easily causes waterlogging and root rot within the bed, but also easily causes the occurrence and spread of soil-borne diseases. Therefore, flat-bed cultivation should be changed to ridge cultivation. If flat-bed cultivation has already been adopted, the center of the bed can be turned into the ridge back by combining with earthing up. Generally, earthing up is done in 2-3 rounds to prevent excessive earthing up at one time from affecting root growth.
Point two,In summer high temperatures, by continuously pinching off the growing tip and renewing the leader to carry out curved-stem training, problems such as excessive vegetative growth and poor fruiting caused by straight-stem training can be solved. When the first and second flower clusters bloom one after another, pinch off the growing tip leaving 2 leaves above the second flower cluster. Select the most robust side shoot to keep as the central stem to continue growing upward. Using this method of continuous pinching off the growing tip can form a curved and compact plant shape, which helps reduce the harm of strong light and high temperature, resulting in higher yield and better quality.
