If you are planting sugar maple trees, select a site in full sun for best results. The tree will also grow in partial sun, with at least four hours of direct, unfiltered sun every day. A sugar maple tree growing in deep, well-drained soil is happiest. The soil should be acidic to slightly alkaline. Once you have finished planting sugar maple trees, they will grow at a slow to medium rate. Expect your trees to grow from one foot to two feet each year. When you are caring for sugar maple trees, irrigate them during dry weather. Although they are fairly drought tolerant, they do best with soil that is constantly moist but never wet.
