Trees Bigtooth Maple

Introduction

The Bigtooth Maple (Acer grandidentatum) is a deciduous tree with its distinctively large, toothed leaves, which turn a vivid array of red, orange, and yellow in the fall. It typically reaches 20 to 40 feet with a similar spread, providing an excellent option for adding shade and striking autumn color to residential landscapes. Its compact size and adaptability make it ideal for various uses, including as a specimen tree or in mixed woodland settings. The Bigtooth Maple’s attractive bark and leaf shape add textural interest, enhancing the natural beauty of any garden or yard.

Maintenance

The Bigtooth Maple requires medium watering to thrive, but is adaptable to short periods of drought once established. It prefers full to partial sun exposure, allowing it to exhibit the best fall foliage color. Plant it in well-drained soil for optimal growth, though it is tolerant of various soil types. Pruning should be done in late winter or early spring to maintain its shape and remove dead or crossing branches. This tree is generally low-maintenance with good resistance to common pests and diseases; however, young trees may require protection from deer browsing in some areas.

Beneficial additions for San Antonio homeowners:

• Heat Tolerance: Bigtooth Maple performs best with afternoon shade in the hottest parts of San Antonio. Protect from the intense western sun for the best foliage.
• Mulching: A 2–3″ mulch layer helps conserve moisture and protect roots from summer heat.
• Watering: Young trees need supplemental irrigation during summer droughts; established trees tolerate short dry periods but appreciate deep watering in extended heat.
• Soil Note: Prefers alkaline or neutral soils; avoid poorly drained or heavy clay spots.
• Leaf Drop: Expect significant leaf drop in autumn—plan for raking or use as natural mulch.
