Maple trees are a versatile tree that can grow almost anywhere. They are seen all across the United States and Canada. However, there is a reason that maple trees are more prevalent in cooler, wetter climates. There are some specific care methods that should be taken to promote healthy growth of maple trees, as well as certain elements that maple trees need to grow.
Maple trees are found in U.S. hardiness zones 3 to 9. This encompasses states from Minnesota to Texas and Florida and includes most of the United States. Although maple trees are hardy and can withstand many different climates, they are typically found in cooler climates, such as those found in the Northeast and North. Many maple trees also grow in Canada. While hardiness is one factor in the growth of maple trees, many other factors are also involved.
Maple trees grow best in a soil that has a neutral to acidic pH. This is a pH reading of 7 and under. A range between 6 and 7 is ideal. You can get a soil test kit at any gardening supply store to test the pH of your soil. Maple trees prefer sandy and well-drained soil. If you have clay soil you can either add sand to the soil, or you can raise the area where the tree is planted to make it higher than the surrounding yard.
Maple trees prefer moist areas. However, the soil also should be well-drained. Most maple trees ideally should receive 1 1/2 inches of water each week. Rain is ideal, but you can also water the maple tree. The best way to determine how much water a maple tree is getting is to place a rain gauge near the tree. You can also water the soil when it starts to feel dry to the touch. The soil should be kept slightly moist, but never soaking wet.
Some fertilization is also required for effective growth of maple trees. A slow-release fertilizer, using a 10-10-10 NPK formula, is best. The trees should be fertilized twice a month during the spring, and once a month from summer until fall. Fertilize from about 1 foot away from the trunk to 3 feet away for maximum effectiveness.
Maple trees can withstand a variety of light conditions. The best lighting conditions for maple trees are full to partial sunlight exposure. The amount of sunlight depends on the location of the tree. In cooler climates, the maple prefers full sun. However, in warmer climates, the maple tree can wilt under full sun exposure. Partial shade is best for warmer climates.
