Another thing that makes the roots grow a lot is the extract or slurry of nettle is an excellent biostimulant that enhances development and strengthens the natural defenses of plants. For its preparation it is necessary to collect the nettle, having to macerate 1 kg of fresh nettle in 10 liters of water. They must remain in maceration for 10 days, stirring every 2-3 days. Once it is verified that there are no more bubbles and that a film has been created above the water, the mash is ready to be filtered and stored in tightly closed containers in a dark place. To use it has to be diluted 20 times in water and can be applied throughout the year, repeating the application every 10-15 days.
