There are three typical mistakes that almost all holidaymakers make when watering tomatoes.
The first mistake is to water tomatoes directly with well or fountain water. This happens often, especially when gardening associations set specific days for watering. Many people try to deplete their water supply by turning on the tap and pouring in as much as possible. However, there is a problem with the water temperature. It can be too low or too high. Tomatoes are very sensitive to temperature changes, and fluctuations can have a negative effect on their roots. The best way to water tomatoes is with water that is at outside temperature.
The second mistake is related to intermittent watering. This means that at first it is not watered for a long time, and then watered abundantly. Some recommendations say that tomatoes should be watered deeply three to four times before flowering, and then stop watering. This can work well in the open field, but for greenhouses or indoor soil, regular, moderate watering is recommended. Indoor watering is a compromise between preventing plants from drying out and ensuring a proper harvest. Experience shows that the less tomatoes are watered during ripening, the tastier they become.
The third mistake is watering tomatoes at night on the leaves. The water that settles on the leaves contributes to the development of diseases. Microscopic water droplets on the leaves can cause disease spores, including late blight, to germinate. In addition, watering at night can promote the formation of dew on the leaves, which also leads to the formation of droplets on tomatoes. It is recommended to water tomatoes only in the first half of the day.
