Properly identifying the plant in your yard as a crab apple tree can make the difference between a flourishing specimen and a malnourished disaster. Making the determination that it is a crab apple tree doesn't have to be a guessing game, however. In fact there are a number of visual clues revealed in the leaves of the tree that make identification simple and accurate.
Determine the size of the tree's leaves. A crab apple tree has leaves that are typically 4 to 8cm in length.
Identify the shape of the leaves. The leaves on a crab apple tree are oblong or even oval in shape.
Feel the underside of the leaves. A young crab apple tree has leaves with a downy underside.
Look at the tip and sides of the leaves. A crab apple tree will have leaves with pointed tips and jagged, toothed edges.
Determine the colour. A crab apple tree has light green leaves in the spring and darker green in the summer into fall.
