Plants need good soil for their development. If the garden soil is depleted after multiple tilling, make it fit again with a soil activator. When and how is it used?

In a nutshell

  • if beds are used intensively, there are not enough organic residues and the number of microorganisms decreases
  • emaciated floors are the result
  • Soil activators contain adjuvants that add nutrients to depleted soils, improve soil structure and increase the number of microorganisms
  • Soil activators are offered as granules or liquid
  • Time and frequency of application depending on the nature of the floor problems

soil activator

A soil activator is a substance artificially made from organic materials. He is used for

  • improvement of the soil structure
  • Optimization of soil fertility
  • Increase in the number of microorganisms
  • Increasing the nutrient content of the soil

Soil-activating products are offered as granules or liquid. We recommend the uncomplicated use of granules.


Main components of the soil activator

  • humus
  • humic acids
  • rock flour
  • red algae
  • silica
  • nitrogen
  • magnesium
  • calcium
  • phosphate
  • trace elements

Notice: Soil activators are often added to microorganisms, for example Azotobacter bacteria. These initially feed on the organic components of the soil activator. When applied to garden soil, they multiply, breaking down organic matter and increasing soil vibrancy.


Soil activators are effective over the long term when there is sufficient organic matter. On beds that receive regular composting, the development and multiplication of the valuable microorganisms is guaranteed even without the addition of an artificially produced soil activator.

When and how often it is used depends on the severity of the soil problems. Heavily loaded beds can be optimized by regularly adding a soil activator.

Regular cultivation of heavy feeders such as zucchini can quickly deplete soil.


In nature, humus is continuously formed from organic waste. Humus forms the basis of life for the microorganisms. In the garden, adding soil-activating substances can help maintain or restore the natural balance.

The advantages at a glance

  • colonization of microorganisms
  • Development of a good soil structure
  • Increase in soil fertility
  • Protection against dehydration
  • Defense against fungal diseases and root thatch
  • Prevention of moss colonization
  • Optimization of humus formation
  • Substitute for lawn lime


If the lawn becomes matted, a soil activator can help. Microorganisms that can no longer find sufficient food retreat to deep regions or die off. The soil structure is changing, the soil is becoming increasingly dense and impermeable. Waterlogging is the result.

A soil activator gives the lawn a fresh kick. With regular use, you can look forward to beautiful green lawns.

Soil-activating products are usually offered as granules. Use a spreader to apply the soil activator. Normally, one or two applications a year are sufficient. We recommend applying in March and October.

Instructions for use on lawns

  1. Scarify the lawn.
  2. Distribute the granules evenly over the lawn in the amount specified on the package insert.
  3. Water the lawn.
  4. Do not mow the area for two weeks.

The effect is already visible after a week.

Vegetable and ornamental plant beds

By using a soil activator, emaciated ornamental and useful plant beds are brought back to life.


  1. Loosen up the soil.
  2. Distribute the granules with a spreader or with a spreading aid.
  3. Water the areas.

Notice: Two applications of the soil activator per year are normally sufficient to strengthen the vitality of ornamental and crop plants. In the case of special soil problems, for example heavily compacted soil or extensive weed and moss infestation, you can use the auxiliary agent several times a year.


The dosage of the soil activator depends on the type of use. Observe the information on the package leaflet. The following table should serve as a guide.

desired effectDose per square meter
General soil improvement150 to 200 grams
Increasing soil fertility on crop beds150 to 200 grams
strengthening of the lawn100 to 200 grams
Optimization of the ornamental plant bed100 to 150 grams

Notice: For new plantings and transplants, we recommend mixing the soil activator with the excavated garden soil. This gives your plants perfect starting conditions!

frequently asked Questions

Can soil-activating substances also be produced in-house?

In addition to regular composting, watering with plant manure is an excellent way to improve the soil. On the lawn, mulch mowing is seen as an opportunity to revitalize the soil.

What precautions should be taken after applying the soil activator?

The treated beds and lawns do not pose any danger to children or animals.

When is the best time to use a soil activator?

Soil-activating additives can be used all year round. For floors subject to normal stress, we recommend use in spring and autumn.

Can rose borders benefit from the addition of a soil activator?

Beds with old rose bushes and perennial perennials can achieve new blooms by using a soil activator. Spread the granules around the plants and work them in lightly with a rake or hoe. Water the bed.

What is the difference between a soil activator and a fertiliser?

A fertilizer is used to provide nutrients to the plants. With a soil activator, the structure of the soil is changed over the long term. Most soil-activating products have some fertilizer added to them.
