    For the winter, I covered the strawberry bed with fallen walnut leaves. But I recently read that they contain the toxic substance juglone. Now I’m worried: will such shelter harm my berry plantation?

      — The maximum amount of juglone in walnut leaves accumulates from the middle of the period of fruit ripening (that is, in the summer in green leaves, and even more in the green peel that covers the ripening fruit). But by the autumn leaf fall its concentration decreases significantly, and juglone does not have such a negative effect on other plants. Therefore, leaves that have turned yellow and fallen naturally can be used for shelter.
