英语作文,描写种植物的过程.
While planting different types of trees differs in the details,all trees eventually end up in a hole.But not any old hole will do.
The most common mistake when planting a tree is a digging hole,which is both too deep and too narrow.Too deep and the roots don’t have access to sufficient oxygen to ensure proper growth.Too narrow and the root structure can’t expand sufficiently to nourish and properly anchor the tree.
As a general rule,trees should be transplanted no deeper than the soil in which they were originally grown.The width of the hole should be at least 3 times the diameter of the root ball or container or the spread of the roots in the case of bare root trees.This will provide the tree with enough worked earth for its root structure to establish itself.
When digging in poorly drained clay soil,it is important to avoid ‘glazing’.Glazing occurs when the sides and bottom of a hole become smoothed forming a barrier,through which water has difficulty passing.To break up the glaze,use a fork to work the bottom and drag the points along the sides of the completed hole.Also,raising the bottom of the hole slightly higher than the surrounding area.This allows water to disperse,reducing the possibility of water pooling in the planting zone.
