      • AquaSave–2 g per liter of soil
      • PowerFlour–1 g per liter of water, 0.2 g per m²

      Hectare figure for Premix Depot and AquaSave from our trials: across 35 trials the average was 1.7 kg/ha per application with 2.7 applications, so around 4.4 kg/ha per season (example from the trials: 5 × 2 kg/ha = 10 kg/ha). The figure is a guideline for fields, farmland and lawn. For PowerFlour we calculate areas at 0.2 g per m² (2 kg per hectare). We are happy to agree the exact quantity with you.

      Good to know

      Frequently asked questions.

      What is each product for?

      Premix Depot nourishes the soil with calcium, magnesium and sulfur. AquaSave stores water in the root zone. PowerFlour feeds plants through the leaf. All three are main products and complement each other.

      Do I have to use all three?

      No, each product works on its own. Together they cover soil, water and leaf.

      In what order do I apply them?

      Mix Premix Depot into the soil before planting, work AquaSave into the root zone when potting or repotting, then spray PowerFlour onto the leaves once a week.

      Which plants are the products suitable for?

      Premix Depot suits houseplants, balcony and garden plants, vegetables, herbs and fruit, but not acid-loving plants such as rhododendrons and blueberries. PowerFlour is meant for garden and ornamental plants. AquaSave also works in other growing media.

      What must I not do with AquaSave?

      Do not leave it on the surface, do not dissolve it in water and do not spray it onto the leaves.

      What do I need to know about PowerFlour?

      Shake before and during application. A suitable wetting agent is recommended; follow its dosage. Spray in the morning or late afternoon, not in direct sun or heat.

      How do I store the products?

      Keep dry and sealed, protected from moisture and out of reach of children. Not for consumption. Avoid dust and eye contact, wash your hands after use and do not exceed the dosage.

      What is the difference between soil fertilizer and foliar fertilizer?

      A soil fertilizer such as Premix Depot is worked into the soil and supplies the roots with calcium, magnesium and sulfur over the long term. A foliar fertilizer such as PowerFlour is dissolved and sprayed onto the leaves, so the nutrients enter the plant directly through the leaf. Foliar feeding complements feeding through the soil, for example when nutrient demand is high.

      How does a mineral water retainer for plants work?

      AquaSave is a mineral water retainer with humic substances. It is worked into the root zone when potting or repotting, absorbs water and releases it again when the plant needs it. That way you water less often, for example on holiday or in hot weather.

      How often should I feed plants with foliar fertilizer?

      PowerFlour is sprayed on once a week, in the morning or late afternoon and not in blazing sun. The dosage is 1 g per liter of water; 100 g makes 100 liters of spray mix.

      How much fertilizer and water retainer do I need per liter of soil?

      That depends on how much soil you have. You will find the dosage per liter in the Application section, and the quantity calculator works out the rest for you.

      Are the fertilizer and water retainer also available in larger quantities?

      Yes, Premix Depot, AquaSave and PowerFlour are also available in a 10 kg bucket, for example for raised beds, fields, greenhouses, trees and meadows. Simply request the bucket through the contact form.
