Remove scale insects from citrus plants
This tip was created by chance:
I placed two small (tree-grown) lemon trees that were full of scale insects on the balcony.
After a few days, I saw two garden snails (about 20 cents in size, with a beige / black housing) make it a pity - I thought that's it then ...
But as long as there were scale insects, the snails did not bend the lemon trees. After some time, the snails even had offspring and all the scale insects were destroyed.
