Show SCRAPING BARK FROM TREES In Case of Ordinary Healthy Trw Treatment Is Advocated by Penn-ylvanla Penn-ylvanla Zoologist, As to the advisability of scraping rfcugh or shaggy bark from apple trees, the state zoologist of Pennsylvania Pennsyl-vania has the following to say: This depends upon the conditions In general. I advise such treatment, especially for rough, scaly bark on old trees; but if It be bark that has boen roughened by the injurious action ac-tion of soil sprays, or by burning with fire or some other injury, I am satisfied it would be wrong, because this is the tender bark beneath just what a scab of an animal is to a sore which It is protecting. Therefore, If the bark beneath ba tender, so that it would be injured by being scraped, It is best not to do it. In the case of an ordinary healthy tree it is certainly best, but at injured places, such as above mentioned, it is advisable to scrapo gently, if at all. On an old tree one cannot apply enough pressure with a short-handled hoe or bark scraper to do any injury, and this will remove many insect pests, such as coddling moth, woolly aphis and certain hibernating creatures, crea-tures, and expose scale insects and other pests to the action of the weather, weath-er, and of the insecticides to be ap plied before the leaves appear. |
