Various alternatives are available for the hobby gardener. These include, for example Rooting powder from algae extract. These products also contain natural growth hormones as well as nutrients and trace elements. Agents with soil additives such as silicate colloid are also suitable. They indirectly strengthen the roots by keeping phosphate available and thus enhancing the potting soil.
consistency
Most of the root activators have a powdery consistency. Rooting powders can be used in many ways. You can use the activator with the Potting soil Mix, sprinkle directly into the planting hole or dissolve in the irrigation water. There is also the option of first dipping the cutting into the powder and then planting it as usual. Alternatively, there are granulated, tablet-shaped, gel-like or liquid root activators, which are usually administered with the irrigation water. For the lawn, we recommend lawn sand products that are enriched with root activators. A good example of this is the lawn sand from Plantop.

Packing size
Depending on the consistency, root activators are available in different packaging sizes. A lot is possible from 40 grams to 20 kilograms and from 50 milliliters to one liter. We advise you to pay less attention to the content - i.e. the exact kilograms or liters - and more to look at the range of the respective product. How many plants can you use the activator and how often? In combination with the costs, these values provide information about the price-performance ratio.
Packaging quality
It is advantageous if the powder, granules, tablets or gel are sold in resealable packaging. This makes it easy for you to optimally store the root activator even after opening and to preserve the ingredients. However, granules in particular often come in a simple sack, as you know it from potting soil. It rarely has a resealable packaging. Powder in a container with a practical screw cap or gel / liquid in a bottle-like container is therefore better.
