G., Colora, Md., writes : " I enclose a piece of an apple root from a small seedling tree. I would like to know, through the Gardener's Monthly, something of its natural history. What is it? What is its cause, prevention, or remedy? I presume it is no new thing, but I never saw it described in print, and I have no doubt many others are alike interested".
[There are numerous species of thread-like fungoid plants that feed on the healthy roots of trees, and finally lead to disease in plants. These apple roots are infested by one of these, and the effect is to injure the foliage, and finally affect the whole plant. The exact species no one can tell in this condition. It is not material to the practical question raised by our correspondent. The only remedy we know, is to destroy such infested plants. - Ed. G. M].
