Extremely dry and hot summers put great pressure on vegetation. This even applies to very deep-rooted trees that can no longer find enough water and soon let their leaves droop alarmingly. In order to alleviate drought stress and avoid long-term effects, trees and shrubs should be watered in such phases.
Freshly planted young trees in particular need a lot of water
When trees need water
Basically, it is not necessary to water trees that have been planted out, as they are self-sufficient through their root system. Watering is only necessary in very dry and hot weather, since even a heavy thunderstorm is not enough for the water supply if there has been no rain for weeks. In addition to dry and drought periods, there are other reasons why watering trees makes sense:
- Freshly planted young trees need a lot of water so that they grow better.
- Trees grown in pots need to be watered regularly.
- Additional watering makes sense in summer, even with narrow plantings or heavily compacted soil.
- In addition, it should be watered even if the winter is dry.
How much water trees need
The water requirements of trees vary greatly: some trees and shrubs get by with very little water, while others can even tolerate waterlogging. Depending on their size and foliage, our native forest trees usually consume a lot of water and require between nine and 14 liters of water. Of course, smaller and less leafy specimens need to be watered less accordingly.
How to water correctly
Pay attention to these tips when watering:
- Water trees and other plants early in the morning or late in the evening if possible.
- Always water from below, not over the leaves.
- During longer periods of drought, water slowly: always wait until a gush has soaked in and don't empty the whole can at once. Otherwise, the water will simply run off because the dry soil cannot absorb any more water.
- If possible, use rainwater or stagnant tap water.

Birds and insects are also thirsty in dry summers: you can install a drinking trough in a raised, cat-safe place.
