Watering trees: a comparison of watering bags, watering cans, watering rims or drip irrigation?

Today, there are various ways to water a tree. From the classic watering can and watering rings to drip irrigation and watering bags, there are numerous systems that differ in effort, cost, and effectiveness.

But which system is suitable for which tree? And which method actually delivers the water to where it is needed?

The answer depends on several factors: the age and location of the tree, the available time, the soil type, and of course, the budget. In this article, we compare the main watering methods and highlight their respective advantages and disadvantages.

Why the irrigation method is important

Many people focus primarily on the amount of water used when watering their plants. However, the speed at which the water is released also plays an important role. If water is released too quickly, it can run off the surface or only moisten the upper layers of soil. Especially in compacted or dry soils, this often results in less water reaching the root zone than expected.

Slow watering gives the soil time to absorb the water. This allows deeper soil layers to be reached and the moisture to remain available for longer. You can find more information in the article. How can I water trees properly??

An overview of the most important irrigation systems

Watering can and garden hose

Traditional watering with a watering can or garden hose is the most widespread method. It offers maximum flexibility and requires no additional equipment.

Advantages:

• sofort einsatzbereit
  
• no acquisition costs for special systems
• flexible use

Disadvantages:

• high time expenditure
• physically demanding when drinking large amounts of water
• Risk of surface runoff
• Water often only reaches the upper soil layers.

This method can be particularly useful for smaller trees and occasional watering.

The pouring rim

A watering basin consists of a ring-shaped wall of earth around the trunk. It prevents water from running directly away from the tree and directs it specifically towards the root area.

Advantages:

• easy to apply
• low cost
• improves water distribution

Disadvantages:

• Regular maintenance is necessary.
  
• can be damaged by rain or gardening work
• reduces evaporation only to a limited extent

Watering rims are particularly suitable for newly planted young trees.

Drip irrigation and soaker hoses

Drip irrigation systems release water slowly and continuously into the soil. They are frequently used in larger gardens, orchards, or professional plantings.

Advantages:

• very efficient water use
  
• low evaporation losses
• Automatic control possible

Disadvantages:

• installation effort
• higher acquisition costs
• Maintenance Required
• less flexible when changing locations

This solution can be useful for larger areas or permanently established plantings.

irrigation bags

Irrigation bags are attached directly to the trunk and filled with water. Alternatively, they can be attached to a stake in the root area of ​​the tree. The water is slowly released into the ground over several hours.

Advantages:

• slow water release
• Easy to use
• less time
• Water reaches the root area evenly.
• especially suitable for young trees and urban trees

Disadvantages:

• Purchase costs are higher than for a watering can.
  
• Regular refilling is necessary
• Not suitable for every planting situation

Why are irrigation bags so effective?

The principle is simple: Instead of applying 75 or 100 liters of water at once, a Irrigation bag The water slowly seeps into the ground through small openings over several hours. This allows even dry or compacted soil to absorb the water more effectively. Less water runs off the surface or evaporates, and the tree receives a more even supply. This method also saves time because the bag only needs to be filled once.

Why slow irrigation is important

Regardless of the system chosen, a similar relationship is evident in many situations: the slower the water is released, the better it can be absorbed by the soil. This is especially true in the following cases:

• compacted soils
• dry soils
• Slopes
• urban locations

Slow watering reduces surface runoff and improves the chances that water actually reaches the roots. You can learn more about this in our articles on... Recognizing soil compaction and improve Why trees can dry out despite rain.

Which system is suitable for which tree?

There is no one-size-fits-all solution. For small gardens and occasional watering, a watering can or hose is often sufficient.

• Newly planted trees often benefit from a watering basin.
• Drip irrigation can be useful for larger plantings.
• For those who want to water individual trees as evenly as possible over a longer period of time, watering bags offer a practical solution.

Ultimately, what matters less is the system itself than whether sufficient water reaches the root area slowly and regularly.

Common mistakes when watering trees

Here's an overview of the most common mistakes when watering trees:

1. Too often, small amounts of water are used instead of less frequent, thorough watering. A few liters usually only moisten the soil surface. Larger amounts of water are better, as they slowly soak in and reach the root zone.
2. Pour the water directly onto the trunk. Most of the fine roots are not located directly at the base of the trunk, but further out in the root zone. The water should soak in there as slowly as possible.
3. Watering too quickly. If water is applied in a short time, it often runs off the surface of dry or compacted soils before reaching the roots.
4. Only begin watering when the weather is very hot. Trees benefit from regular watering during extended dry periods. Waiting until the leaves are already drooping or discolored often means it's too late.
5. Only moisten the soil surface. The crucial point is that the water penetrates deeper soil layers, where a large proportion of the water-absorbing fine roots are located.
