Natural precipitation does not fall nearly as regularly as it would be necessary to ensure healthy and lush plant growth. The summers are getting hotter and hotter and a few days without rain are enough to damage the plants. If the rainwater is collected and distributed as required by a sprinkler system, this optimizes the use of water and labor.
Clear yes. Once set up, the system works automatically and does not require any further manual support. The vegetation is optimally watered according to the soil conditions and location and thanks to healthy growth even with reduced fertilizer application. In addition, there is no overwatering, as a rain sensor switches the system off when there is sufficient rainfall. Modern, WiFi-supported control devices compare location data with weather forecasts and thus save even more water.

The long-lasting and "growing" variant of the usual pouring rim with a capacity of up to 140 liters (with a diameter of 95 cm). The pouring rim formed by excavated soil is one of the absolute basics in gardening and landscaping. This method is now being optimized with the GEFA pouring rim.
A 30 cm high - made of 3 mm thick special plastic (LDPE) - ensures the big one Filling capacity and at the same time protects against unwanted road salt entry in the winter months.
The pouring edge is inserted 10 cm into the ground and the 20 cm remaining above ground, e.g. B. with the fix Special adhesive tape fixed against each other. We recommend adding growth to the overlap. In this way, the pouring edge can be adapted to further root growth in the future. The new pouring rim clip is now available for even easier fixation. This simply connects the two ends and saves you from sticking with the GEFA special adhesive tape.
The GEFA pouring rim is UV-resistant, 100% recyclable and, like the clips, can be reused.

Robust watering bags are suitable for mobile irrigation for new plantings or for the maintenance of existing trees in drought conditions.
Depending on the product variant, the irrigation bags hold 50 - 60 liters of water. The filling quantity varies depending on the size of the trunk. The water is released directly to the root area through a small opening in the bottom. Depending on the manufacturer, the draining time is approx. 5 - 8 hours per filling.
1. Place the watering bag around the tree. 2. Pull the zipper up to the top. 3. Erect the sack using the loops to allow easy filling. 4. The generously dimensioned filler neck is located on the back. 5. Fill in water using a hose until the irrigation bag is full.
A single irrigation bag is suitable for trees with a trunk circumference of 8 cm - 30 cm.
In order to also water existing trees with a trunk circumference of more than 30 cm in dry periods, it is possible to use two or more bags, using Connect zipper. This increases the water capacity to 100-120 liters or more.
Our experts recommend the GREENDROP® irrigation bag.

As the theft of the irrigation bags in public spaces has been reported repeatedly in the past, we have launched a version of the Watercoat III with theft protection. Two eyelets on the front of the zipper allow it to be "locked" with a padlock.
This makes it impossible for thieves to remove the bag from the location without damaging it.

The increased amount of water in dry months naturally also stimulates weeds to grow. A mulch disc directly under the irrigation sack prevents unwanted sprouting and thus also ensures a tidier appearance in urban areas.
Another advantage of a combination of irrigation sack and mulch disc is the more even and flat dripping. The mulching disc soaks up the water and then releases it evenly to the ground.
Often the soils are highly compacted, which makes it difficult for the irrigation bags to drip off optimally. We therefore recommend the use of the wetting agent AquaSmart from ICL. The wetting agent is able to guarantee the wettability of the root zone over a longer period of time. The water can not only penetrate into the surface or felt layer, but also deep into the entire root zone moisten.

Young trees require special care and consistent watering in the root zone during their crucial early years of growth. Medium- and long-term solutions can be easily integrated directly at the time of planting. At GEFA Fabritz, you will find a comprehensive range of high-quality professional products designed for tree and young tree irrigation needs.
During the first years after planting, newly planted trees must be watered regularly to encourage deep root growth. Watering should initially focus directly in the root zone.
According to FLL guidelines, a suitable watering basin must be formed, with its inner edge positioned above the outer edge of the root ball. This basin can be created using existing soil. However, prefabricated systems are now available for targeted watering: watering rims, slow-release watering bags, technical tools for water retention, and systems that can be installed during planting to provide medium- and long-term water and air supply.
NOTE: Watering within the planting pit, such as with drainage pipes, is not suitable for the first years after planting.
The durable and expandable version of the standard pouring edge, with a capacity of up to 140 liters (at Ø 95 cm). The pouring edge formed by soil excavation is a fundamental tool in gardening and landscaping. This method is now optimized with the GEFA Pouring Edge.
Special plastic
A 30 cm high strip made of 3 mm thick special plastic (LDPE) provides a large filling capacity while simultaneously protecting against unwanted road salt intrusion during the winter months.
Pouring edge installation
The pouring edge is inserted 10 cm into the soil, leaving 20 cm above ground, which can be secured using Fix special adhesive tape. We recommend equipping the overlap with growth allowance so the pouring edge can be adjusted for future root growth. For even easier securing, the new pouring edge clip is now available, which simply connects the two ends together.
Advantages
The inner area of the pouring edge should align with the outer edge of the root ball. Unfortunately, incorrect placements are common. Here are a few tips.
For mobile irrigation of young trees or to minimize drought stress during heat periods, robust irrigation bags are ideal. Depending on the product variant, the bags can hold up to 100 liters of water. The capacity varies depending on the trunk circumference. Water is released directly to the root zone through small openings at the bottom. The drip time is approximately 5 to 8 hours per filling, depending on the manufacturer.
White products exposed to the sun do not heat up as quickly as darker-colored products. We have now applied this physical principle to irrigation bags.
The result is the irrigation bag GREENDROP® “white.”
The background: Some customers reported heat damage to tree trunks caused by green water bags attached directly to the trunk. The water or air between the trunk and the bag can heat up so much that it causes damage. The new irrigation bag GREENDROP® “white” reduces this risk.
Its white color effectively reflects sunlight and prevents the tree trunk from overheating.
In terms of aesthetics, it also offers an advantage – when used in combination with trunk protection paint, it creates a harmonious color scheme.
Efficient ventilation and irrigation are essential for the survival of trees in urban areas, especially in planting pits of construction type 2.
The challenges in urban spaces are well-known: restricted site conditions, overbuilt root zones, disturbed soil conditions, severe compaction, and lack of gas exchange.
With conventional systems, there is a risk that irrigation is carried out through the opening intended for ventilation. This challenge was the starting point for the GEFA LUWA® system. It enables both ventilation and irrigation through a single inlet, ensuring that water does not enter the ventilation pipes. The system separator directs water and air separately into their designated pipes/hoses, preventing the chimney effect.
Providing trees in urban environments with water and air during the establishment phase and beyond is one of the main tasks for planners and practitioners in the green industry.
Lite-Net Water storage net for root supply
The textile water reservoir made of special fleece/felt contains only about 10% material and can store an exceptional amount of air and water in the remaining 90% pores. 1 kg of fleece/felt can store up to 10 liters of water. The reservoir is 100% biodegradable, consisting of 70% PLA (polylactic acids) and 30% cellulose fibers.
The LITE-NET establishment net is placed directly around the root ball to support the tree's establishment. It can be ideally combined with watering rims or irrigation bags to efficiently and evenly transport water to the tree roots.
