If you want to get rid of horsetail in the garden, you should use lime. Horsetail prefers a low-lime, rather acidic soil with a pH of 5 to 6.
If the soil is too acidic, lime can help increase the pH. For example, sowing lupins, whose roots penetrate deep into the ground, is a natural way to loosen the soil. You can find even more exciting garden topics in the regular newsletter from our partner 24garten.de.
