PHYLLIRHOE BUCEPHALA—SHOWING IN THE DARK THE LUMINOUS SPOTS.
Care of Trees and Shrubs.
In view of the drought which prevails in many parts of the country and its unusual severity over extensive districts, the Rural New Yorker suggests to those who have planted trees or shrubs the past spring that there is one method, and so far as we know, says the writer, only one, by which they may be protected against injury or death from that cause. Surface watering has been shown to do more harm than good. The ground is made hard and compact, thus becoming a better conductor of heat while it becomes less pervious to air and moisture. A portion of the surface soil should be removed, and then pailful after pailful of water thrown in until the ground, to a depth of two feet and to a width about the stem of not less than three feet in diameter, has become saturated. Then, as soon as the water has disappeared from the surface, the removed soil should be well pulverized and returned. A covering of boards, straw, or hay, or even of sand or gravel, may then be applied, and the tree or shrub, thus treated, will pass through ten days of additional drought in safety.
As soon as rain comes to wet the earth thoroughly, we think it is better to remove the mulch. Nothing is then gained by permitting it to remain. Mellowing the surface soil about the trees, thus keeping it free from grass and weeds, is then the most that is needed. We would repeat that the present is the season when the female borer deposits her eggs on the stems of fruit trees, and the wash of lime, potash, sulphur, etc. (darkened with lampblack), should now be applied and reapplied during June and July, as soon as washed off by rain.
