You will also find out how you can water your plants efficiently and optimize your water consumption at the same time with clever solutions such as the use of PET bottles or a cistern. Join us on the way to a green paradise that is not only good for your plants, but also for the environment.

2 Overview of different irrigation systems

In the world of garden irrigation, there are a variety of systems that can vary depending on your needs and the type of garden. Here we present three popular irrigation systems: the drip hose system, the sprinkler system and DIY systems that ensure an efficient water supply for your plants.

Drip hose system

The drip hose system is ideal for targeted irrigation along row plantings. It minimizes water loss through evaporation and ensures that the water reaches the root zones directly. This promotes healthy root growth and reduces weed growth. Another advantage of this system is its high water efficiency. However, it does require some initial effort to install and must be checked regularly for blockages caused by sediment or roots.

Sprinkler system

Sprinkler systems are ideal for evenly watering larger areas such as lawns or flower beds. Modern sprinklers can be almost as water and energy efficient as drip systems. They offer different models and settings to suit different watering needs. They can cost more to install and require regular maintenance to ensure efficiency and functionality.

DIY systems

There are numerous DIY options for creative and cost-effective watering. A simple system can be created using a PET bottle and a watering attachment. These systems are particularly practical if you want to water your plants automatically when you are away. Another option is to use a piece of linen fabric inserted into the neck of the bottle to slowly release the water. DIY systems allow customization to the specific needs of your plants and are an excellent option for saving water.

Each of these systems has its own specific advantages and disadvantages that need to be taken into account. Choosing the right irrigation system depends on many factors, such as the size of the garden, the types of plants and your personal preferences regarding handling and maintenance.

3. materials and tools

Materials required

Various materials are required to build an efficient irrigation system, which can vary depending on the type of system chosen. For a simple drip irrigation system, for example, you will need

• Unglazed clay pots with a hole in the bottom, in two sizes, with the smaller pot fitting into the larger one.
• A Water barrel with a capacity of around 120 liters serves as the main water storage tank.
• Plant granules such as expanded clay or Seramis, which acts as an effective water reservoir.
• Various Drip irrigation pipes and Sprinklerdepending on the size and type of areas to be irrigated.
• Connectors, T-pieces and Valvesadapted to the diameter of the pipes to ensure effective distribution of the water.

These materials allow you to create a customized irrigation system that meets the specific requirements of your garden.

Tools for installation

Installing an irrigation system requires a few basic tools to facilitate installation and ensure long-term functionality. The most important tools include:

• Garden shears and Pipe cutter for precise cutting of the pipes.
• Screwdriver and Adjustable wrench (French)to set sprinkler heads and connectors correctly.
• A Spade or a Trencher for the excavation of channels in which the pipes are laid.
• Cable ties and Metal cramps for securely fastening the pipes and hoses along the course.
• Deburrerto ensure that the pipes do not have any sharp edges that could damage the seals.
• Teflon sealing tapeto ensure that all connections are tight and watertight.

These tools are available from most DIY stores or online retailers and make installation much easier by enabling safe and efficient installation.

4. step-by-step instructions for a drip hose system

Preparation

1. Site selection and height adjustmentStart by selecting a suitable location for your rain barrel. The position should be chosen so that it is at least 50 centimeters to one meter above the level of your bed. This uses gravity for the water pressure. If your bed slopes, a lower position for the barrel may also be sufficient.
2. Fitting the tapInstall a tap on your rain barrel. Make sure that the tap connection matches the hose connector. These components are available from DIY stores and should be carefully selected to ensure a tight connection.
3. Filling the garbage canFill the rain barrel with water. It is sufficient if the water level is about ten centimeters above the tap. This makes it easier to raise the barrel if necessary to optimize the water pressure.

Installation

1. Laying the hoseConnect the hose to the tap on the water butt and lay it out along your bed. The end of the hose should be fitted with a hose connector with a water stop to prevent leakage.
2. Testing the water pressureOpen the tap on the rain barrel and test the water pressure by briefly removing the water stop. The water should shoot vigorously out of the hose. If this is not the case, raise the water butt further.
3. Attaching the drip holesUse a hammer and a nail to poke holes in the hose. The size of the nail influences the amount of water that comes out. The higher the water pressure, the smaller the holes can be.
4. Alignment and fixationLay out the hose in your bed so that the drip holes are positioned directly at the roots of your plants. Use cable ties or ground spikes to secure the hose to the ground and ensure even watering.

Further questions and answers about irrigation systems

Question: How effective is watering with PET bottles?
Answer: Watering with PET bottles allows the plant to gradually absorb the water from the bottle. The resulting negative pressure prevents the water from running out too quickly. This method can be used effectively for travel times of up to 14 days.

Question: What type of cord should I use for the water supply?
Answer: Cords made from natural materials such as sheep's wool or cotton are best suited for the water supply. Synthetic or mixed fibers are less suitable. A wet wool cord can also be passed through a straw to prevent it from drying out.

Question: Which irrigation systems are best rated?
Answer: The best irrigation systems include the Gardena smart Sensor Control Set (19202-20), the Gardena Solar Irrigation AquaBloom Set and the Gardena Drip Irrigation Set for raised beds and flower beds (35 plants). These systems have received very good ratings.

Question: How can I organize plant watering when I am on vacation?
Answer: There are several ways to water the plants during a vacation, including: Watering with bottles, watering with a string, watering the plants in the bathtub, using water storage granules, watering the garden well before leaving, putting plants in the shade, cutting back plants and covering beds with mulch.
