GREENDROP® irrigation questions

GREENDROP® irrigation questions

In Germany there is an average of more than 800 mm of precipitation per year. Is automatic irrigation really recommended?

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.

Can you save time and money with automatic irrigation?

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.

How do I know which system is the right one for my customer?

Irrigation bags

Irrigation bags

Robust watering bags are suitable for mobile irrigation for new plantings or for the maintenance of existing trees in drought conditions.

Water to the roots

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.

Easy assembly

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.

Increase volume

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.

Theft protection irrigation bags

Protection against theft of the watering bags

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.

Irrigation bags and mulching discs

Irrigation bags and mulching discs

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.

Advantage with wetting agent

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.
