Ivy or any vine that runs perpendicularly up a tree does not injure it, unless branches from the vine extend along the branches, and by its mass of leaves smother the leaves of the tree. Vines like Wistaria that coil around a trunk do injure trees.

" W. C. B.," Philadelphia, writes: "In Laurel Hill Cemetery there is a cypress about thirty feet high, the trunk and lower branches of which are completely covered with a thick growth of Hedera, to the height of fifteen feet. The branches of the cypress covered by the Hedera are all dead, while the whole tree from immediately above the Hedera is very healthy. From a little distance, this tree presents a very grotesque appearance, there being just half of each growth, each being so healthy, and the foliage forming such a contrast".

[The English Ivy, Hedera, like all other vines, will smother the foliage of the tree it grows over; and wherever it gets the chance to grow over foliage in this way, will necessarily destroy the branches. So long as the vine is confined to the trunk or main branches, no injury results to a tree by having a vine grow straight up over it. When it coils around a trunk, as in the case of a Wistaria, it is a serious injury. - Ed. G. M].

"S. T. W.," Forest Grove, Oregon, writes : "It may be interesting to you and some others to know that the English ivy blooms here profusely, and that it is a famous honey plant. A few days ago I picked a bunch, and to my surprise found many of the flowers completely covered with a pure white sugar. The plant from which it was taken grows on a large oak tree, covering the trunk for about twenty-five feet, and bids fair before many years to entirely cover it. From your knowledge can you say whether it will finally kill the tree or not ?"

[The ivy does no harm whatever to trees, so long as it is confined to the trunk and large branches. If the ivy extends so far as to interfere with the foliage of the tree which supports it, then it is an injury. - Ed. G. M].
