Plant Description
Trident maple is a small to medium-sized, spreading deciduous tree that normally grows about 5–20 m tall with a trunk up to 50 cm diameter. The plant can be planted in full sun or partial shade on any well-drained, acid soil and is quite tolerant of salt, air pollution, wind and drought. It performs well in urban areas where soils are often poor and compacted. Take care to plant the bud union above the soil level. Water in well and keep soil moist until tree is established. Fertilize when planting and again after new growth appears. Prune tree when planting to encourage new growth. Twigs are slender, flexible, reddish brown with gray pubescence. Buds are conical, reddish brown sharp pointed. Bark is scaly and exfoliating on larger stems, gray outer bark flakes off, revealing lighter reddish brown patches.
