WATERING TREES, ETC.Wehave observed many persons copiously watering young trees and garden plants.1. In many cases much water is a positive injury. The roots draw up a larger supply of liquid than there is vigor in the tree to digest or appropriate. In such cases the tissue is enfeebled, the roots decay, and the tree perishes in the trying heats of July and August.2. It often happens that wetting the tree itself is much better than watering the root. Take a watering-pot and drench the leaves, and limbs and trunk, several times in a day. In a small tree a large bunch of cotton or rags may be put in the crotch and saturated with water. It will gradually trickle down the stem, and also evaporate, keeping the leaves in a moist medium. This trouble is worth while in case of rare trees difficult to be obtained. A tree perspires as really as an animal or a man. Every leaf is furnished withstomataor pores, the number and size of which determine the amount of perspiration. Of course, as they vary in different plants, there is a corresponding difference in the amount which they perspire. Plants which grow in exposed situations, scorched by the sun, have a structure which admits but slight perspiration, while those which grow in the shade and in moist places perspire copiously.It is upon this state of facts that watering the tree itselfis beneficial. The exhalation from the leaf is diminished, and sap retained within the tree. Beside this, the leaf and young green bark absorb some moisture.3. Where watering is resorted to it should not be upon the surface; especially is this injurious in clay soils. The moisture is immediately exhaled, and the sun hardens the wet earth into a crust, nearly as impervious to light, and air and moisture, as if it were sheet-iron. Let a slight trench be opened, and after the water has sunk away, replace the earth and pulverize it. In this way no baking will take place.4. But the best method of watering by the root, is that which is technically denominatedmulching. Cover the surface of the ground beneath the tree or shrub with three or four inches’ thickness of coarse, strawy manure. If watered through this the earth will not bake; the moisture will not evaporate; the root will be shielded from the sun, and enriched by the infiltration of the juices of the manure.
