There are three typical mistakes that almost all holidaymakers make when watering tomatoes.
The first mistake is to water tomatoes directly with well or well water. This happens often, especially when gardening associations set certain 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 may be too low or too high. Tomatoes are very sensitive to temperature changes, and fluctuations can negatively affect their roots. It is best to water tomatoes with water that is at outdoor temperature.
The second mistake is related to intermittent watering. This means that it is not watered for a long time first, and then watered abundantly. Some recommendations say that tomatoes should be watered three or four times deeply before blooming and then stop watering. This can work well in open ground, but for greenhouses or indoor soil, regular, moderate watering is recommended. Indoor watering represents a compromise between preventing plants from drying out and ensuring proper harvesting. Experience shows that the less tomatoes are watered during ripening, the tastier they become.
The third mistake is to water tomatoes by the leaves at night. The water that settles on the leaves contributes to the development of diseases. Microscopic droplets of water on the leaves can cause disease spores, including late blight, to germinate. In addition, nighttime watering can promote the formation of dew on the leaves, which also causes droplets to form on tomatoes. It is recommended to water tomatoes only in the first half of the day.
