Drip irrigation describes a watering method in which the water is released into the ground, droplet by droplet, over a long period of time, in a very resource-saving manner. This allows the water to penetrate deep into the ground and reach the roots of the tree particularly well, which means that the tree can be optimally supplied with water.

If growth is delayed during the growing season, ie if the shoots are very short or the leaves are very small, then this is a clear sign of drought stress.

In spring and summer, drooping and wilting leaves, falling leaves and compressed growth (very short shoots) are clear signs that a tree is in dire need of water.

There is no general answer to this question. That depends on many factors, such as the type of tree, the size of the tree, the location, the nature of the soil, etc.

But there is a rule of thumb:

A medium-sized tree needs 150-200 liters per watering cycle.

That means two fillings of a tree bath watering bag or one filling of two connected watering bags.

Pour a large amount of water 1-2 times a week.

Recommendation: 150-200l = 2-3 fillings of a tree bath watering bag per watering.

In addition, you can help city trees very well by loosening the upper soil layers to break up the strong compaction of the soil in cities. This often means that when watering or when it rains, the water cannot penetrate the ground at all to reach the roots of the tree, but simply runs off the surface.

If the watering bag cannot be placed normally around the tree for whatever reason, e.g. branches close to the ground or other vegetation, the bag can also be placed next to the tree to be watered.

The tree bag is already very stable by itself and only needs a small amount of support, e.g. from a wooden rod or a metal rod.

Note: Be careful not to damage larger roots when inserting the support into the ground.
