What are different irrigation systems

Irrigation systems in the garden: what makes sense?

The plants in the garden need sufficient water, especially in hot and dry summers. Which irrigation systems are useful and which aids are there?

Garden plants need additional water in summer. But the right irrigation is not that easy to accomplish. It is particularly important that the irrigation water gets deep into the earth. This allows the plants to develop deep roots and become more resistant to drought. Many beds can still use additional water even after a rain shower.

Tip: use rainwater for watering

It is best to use rainwater for watering and watering the garden. In contrast to tap water, it is particularly soft and ideal for the plants. In addition, rainwater saves costs and not only protects your wallet, but also the environment. Rain barrels and cisterns are ideal for collecting the water.

Automatic irrigation with sprinklers

If you want to regularly water certain areas, such as a vegetable patch, you can easily install a reliable irrigation system with the help of a timer, a hose and several sprinklers. For smaller beds, starter sets are sufficient, which contain everything you need: including a flexible plastic hose, plug connections, angles and sprinklers.

Water sprinklers distribute the water evenly in the bed.

To get by with as little hose as possible, place a central sprinkler in the middle of the bed. This is connected to the other sprinklers on the sides so that the entire bed is covered. The type of sprinkler depends on the size of the bed. If the areas are manageable, there should be several flat spray nozzles. These should not be too high so that not so much water evaporates before it reaches the bottom.

Timer and the best time to water

The timer for an irrigation system is attached directly to the tap.

There are timers for taps from different manufacturers. In principle, a simple clock in which you can program times and days of the week is sufficient. For tech-savvy people, there are also models that can be controlled with a smartphone.

Ideally, beds and plants should be given water early in the morning - around the time of sunrise, so that the leaves can dry off before the sun really burns. Otherwise the water droplets act like burning glasses and the leaves are damaged.

Another good time is in the evening, when the sun is already lower and no longer has full power. Then the watering time should be set so that the plants do not go too wet into the night. That would encourage fungal infestation.

Micro-drip systems for individual plants

In contrast to water sprinklers, so-called micro-drip systems are more suitable for watering individual plants. With these water-saving drip systems, plants can be watered in a targeted manner, for example in flower boxes or borders. Of course, the drippers can also be controlled via a timer.

In a vegetable patch, micro-drip systems are not so ideal because the plants there - provided that the so-called crop rotation is adhered to - are planted in different locations. The drip systems would then have to be adjusted every time. Water sprinklers, on the other hand, can usually remain standing.

Tomato water dispenser

A clay pot filled with water provides a tomato plant with water for several days.

Individual plants can also be watered specifically and over several days with simple tricks - without the use of technology. A clay pot with a hole in the bottom is recommended for watering tomatoes. This is buried close to the plant and filled with water. This way the water reaches deeper roots.

Water storage for flower boxes and raised beds

There are other irrigation aids to ensure even moisture for a few days: closed containers made of clay or plastic bottles that serve as water reservoirs and are easy to fill up.

  • You can buy clay water tanks or make them yourself from two clay pots. The clay pots were fired at low temperatures and therefore have large pores. They are buried in the earth, only the opening for filling in water still looks out of the ground. They slowly release water into the environment through the pores. However, they are not frost-proof and have to be removed from the ground in autumn.
  • Alternatively, you can use a plastic bottle: pierce holes in the lower part of the plastic, bury the bottle vertically and pour water over and over again through the upper opening.
  • Small clay nozzles are suitable for providing watering over the weekend. These are pressed into the ground in a flower box, for example. A simple bottle that stands upside down in the spout serves as a water reservoir. The water is slowly released into the earth via the clay.
