Water the tomatoes in the bed - the weather swings the baton
It would be so easy to water tomato plants on a fixed schedule and amount of time. Of course, a central variable in the cultivation of tomatoes does not play a role. The weather ultimately defines when and how much water is required. In order to harvest healthy and magnificent fruits in the bed, the focus is on the following requirements:
- water thoroughly for the first 3 days after planting
- then give an average of 0.5 liters of water per plant per day
- Before each watering, use a thumb test to check whether the substrate is dry to a depth of 1-2 centimeters
- After the fruit set, increase the amount of water to 150-300 milliliters per tomato fruit
- the temperatures, the intensity of the sun and the exposure to wind make the difference

As much as tomato plants love to spread their deep roots in fresh, moist soil, they loathe wet flowers and leaves. Therefore, always water directly on the floor. A mulch layer of straw or nettles prevents splashing water. In addition, remove the tomato leaves in the lower area.
So the water supply in the greenhouse is right
Since there is no natural amount of rain in the greenhouse, irrigation can be controlled even more precisely. The current temperatures, the lighting conditions and the nature of the soil must be taken into account. You can use the thumb test to determine the water requirements of your tomato plants. The soil should also be allowed to dry out in the greenhouse before you water the next time. Otherwise, similar requirements apply as in the field.
The trick with the water bottle
The more evenly you water, the lower the risk of bursting tomato peel. You can optimize the water supply within the sheltered conditions in the greenhouse with a simple trick: cut off the bottom of a PET bottle. You put this upside down next to a tomato plant to top up the water in the bottle every day.
Pouring in the bucket - avoid deadly waterlogging
Tomato plants in the tub require particular sensitivity when watering. On the one hand, the entire root ball should be moistened, on the other hand waterlogging must be avoided. The thumb test alone does not help here. This is how you can tell how things are going with the tomato roots:
- Do not create a bottom opening in the pot
- instead drill a hole in the side
- close this with a conically ground dowel
The moisture content in the root area can be determined by pulling out the dowel. Any stagnant water can simply drain through the side opening.
Tips & Tricks
Simply leave the shoots on the ground after pricking. Here they not only serve as useful mulch material, but also release valuable nutrients to the roots. At the same time, the plant parts serve as an effective defense against pests.
