  • shipping unit:
    - 20 kg bag
    - pack of 750 g
  • Ingredients: Lignin derivatives, individually approved as a soil conditioner according to § 9 DMG 2021
  • best sustainable water storage
  • increases soil water retention and fertility
  • biodegradable
  • Use for: forestry (forest plants), viticulture (vine), fruit and vegetable growing, tree nurseries (e.g. tree planting)
  • Recommended application rate: from 10 g hydrogranulate per liter of soil
  • GroWit® Hydrogranulate can be safely used for all plantings in conventional and organic farming in Austria and Germany.
  • approx. 3 – 5 years of active, organic water storage (depending on soil type)
  • IMPORTANT! To become active in the soil, the granules must be exposed to water (rain, irrigation, watering, etc.). This allows the granules to retain moisture and release it back to the plant.
  • Storage: Store in a cool, dark, and dry place. Keep out of reach of children and pets! Do not swallow!
  • Shelf life: 1 - 2 years

Your benefits of using GroWit® Hydroganulate:

  • Improvement of the water retention capacity in the soil - GroWit® Hydrogranulate maximises the water storage capacity of the soil - especially during dry periods.
  • Protects trees and plants from drought stress - GroWit® Hydrogranulate forms a water reservoir in the soil to protect plants from plants from water shortages and drought.
  • GroWit® Hydrogranulate decomposes into humus, increases soil fertility and thus forms a sustainable ecosystem in the soil.
  • Nutrients present in the soil are bound and slowly released.
  • No direct leaching of these nutrients. GroWit® Hydrogranulate releases nutrients in a controlled manner.
  • Reduced costs for irrigation, fertiliser and labour: - GroWit® Hydrogranulate in combination with any form of irrigation reduce water consumption as well as energy and labour costs. The advantage is a water saving of up to 40 %.
  • Depending on the soil type, GroWit® Hydrogranulate is active for at least 3 - 5 years - The long-lasting effect of GroWit® Hydrogranulate ensures sustainable soil improvement over several growing seasons.
  • GroWit® Hydrogranulate can be safely used for all plantings in conventional and organic farming.
    - Listed in the input catalog and certified for organic farming in Austria.
    - Listed in the FiBL input list for organic production in Germany.

Recommended application instructions:

  • Reforestation: 50–100 g per plant (depending on plant height and root ball size)
    For plants larger than 50 cm, use approx. 100 g per plant. The granulate must be well mixed with the surrounding substrate in the root area. Avoid layering it as a separate layer.
    Practical tip: When planting bare-root plants in a hole, use 80 g of hydrogranulate for a hole size of approximately 8 liters.
    80 g GroWit® Hydrogranulate = approximately 3-4 large handfuls
  • Container plants: 10–20 g per liter
    - 10 g GroWit® Hydrogranulate for heavy substrates or substrates with a high organic material content.
    - 20 g GroWit® Hydrogranulate for light, well-draining substrates with, for example, a high sand content.
  • Root Dipping: To protect plants from dry stress and heat during longer storage or transport, mix the granulate with water in a 1:10 ratio and wait until the granulate absorbs the water. Then, dip the root ball into the gel for several seconds.
  • New Plantings: 100 g per plant (fruit and vine cultivation)
    The granulate must be well mixed with the surrounding substrate in the root area. Avoid layering it as a separate layer.


Recommended application instructions:

  1. Mix GroWit® Hydrogranulat with the soil substrate.
  2. Incorporate it into the surface to a depth of approx. 5–10 cm.
  3. After applicatoin, water the GroWit® Hydrogranulat to activate it.
