Strengthens the root system

Promotes the formation of fine roots and increases water absorption.

Disease resistance

Contains microorganisms and enzymes that combat harmful soil pathogens.

Faster nutrient absorption

The dissolved nutrients are immediately available to the plants – without the risk of over-fertilization.

Application & Dosage

4-5 applications per month are recommended. More frequent applications are possible in cases of severe dryness.

With watering bag: Dilute 100 ml of liquid fertilizer in 55–75 liters of water. Ideal for young trees, urban trees, and extended dry periods.

The clever irrigation solution

What healthy soil really needs besides NPK 1-1-1

Soil isn't just made up of nitrogen, phosphorus, and potassium. Worm compost brings back exactly what's missing in many places:

Micronutrients in natural, plant-available form

Enzymes & Humic Acids, which improve nutrient absorption

Active microorganisms, which regenerate soil life

Cocoons & young worms, which ensure the ecological balance in the long term.

Results:

This creates a living soil that retains water better, makes nutrients available and sustainably strengthens your trees.

In addition:

Nitrogen (N) for strong growth

Phosphorus (P) for strong roots and flower formation

Potassium (K), calcium, magnesium and sulfur for stable cell structures and healthy plant development

Dosage according to tree thickness (trunk circumference)

Young tree: (trunk circumference: up to approx. 20cm)

100 ml liquid fertilizer

in 55–75 L of water (irrigation bag)

Young to medium-sized tree: (trunk circumference: 20–40 cm)

200 ml liquid fertilizer

in 10–15 L of water (pour carefully)

or in 55–75 L of water (irrigation bag)

Large tree / city tree: (trunk circumference: 40–80 cm)

300 ml liquid fertilizer

Distribute between 1-2 watering bags (75 L of water each)

Alternatively, pour 20–30 liters of water near the ground.

Mature tree: (trunk circumference: > 80 cm)

500 ml liquid fertilizer

Divide the solution among 2-4 watering bags. Apply to the outer root area (crown drip line).

Note: Since it is an organic, microbially active fertilizer, overdosing is not to be expected when used as recommended.

Our worm compost is created - in an animal-friendly and mindful way.

A natural cycle: Our worm compost is created in lively cooperation with compost worms – in a natural cycle, just like the one that takes place in healthy forest soil.

Fertilizing can increase soil fertility, promote growth, enhance soil life and contribute to soil improvement – ​​but not all fertilization is beneficial, because soils can also be over-fertilized.

Organic fertilizer (e.g. compost/worm compost) builds humus and supports soil life, while mineral fertilizer is more focused on individual nutrients (e.g. NPK) and should be used more carefully.

Yes, a soil test is highly recommended. The condition of soil is difficult to reliably assess with the naked eye. Many garden and urban soils are already over-supplied with certain nutrients like nitrogen or phosphorus, while other nutrients are lacking. A soil analysis reveals the actual nutrient content and pH value of the soil and provides specific recommendations for proper fertilization.

A simple soil analysis in Germany usually only costs about €20–40 and can, for example, LUFA laboratories, chambers of agriculture or specialized garden laboratories This can be carried out. The results allow for much more targeted fertilization planning and the avoidance of over-fertilization – this protects the soil and groundwater and ensures healthier trees in the long term.

Yes, trees can also be grown over Tree watering bags fertilized The bag releases the water slowly and drop by drop into the soil, ensuring the fertilizer reaches the root zone evenly. This brings a large portion of the soil around the tree into contact with the diluted nutrient solution, facilitating absorption through the roots.

The important thing is to only... liquid fertilizers Use only the appropriate fertilizer and dilute it sufficiently with water beforehand. Solid components can clog the openings of the watering bag. Strong-smelling liquid manures or thick fertilizer teas should also not be placed in the bag. Liquid organic fertilizers, for example those based on worm compost, can be easily mixed with water and applied evenly via the watering bag.

Typical signs of deficiency include, for example, leaf yellowing/discoloration, premature leaf drop, poor flowering, and reduced growth. You also point out that these signs are accompanied by... Drought stress They can be similar, and you should check the water supply first.
