The Story
Plant Bio
Acer rubrum is a large, fast-growing deciduous tree native to eastern North America, known for its adaptability to a wide range of soil and site conditions. It is one of the first trees to flower in spring and provides some of the most brilliant fall foliage color. As a species, Red Maple is notable for its variability; fall color can range from yellow to orange to brilliant scarlet. Its smooth gray bark on young trees and reddish twigs provide significant winter interest.

Planting
How to Grow
- Select a site in full sun to part shade with acidic, moist soil.
- Dig a hole 2-3 times wider than the root ball, but no deeper.
- Gently tease out any circling roots on the root ball.
- Place the tree so its root flare is visible at the soil line.
- Backfill with the original soil, watering to remove air pockets.
- Apply a 3-inch layer of mulch, keeping it away from the trunk.
Pro Tip
For consistently brilliant red fall color, choose a named cultivar like 'October Glory' or 'Red Sunset' instead of a seedling.
Keep It Thriving
Care Guide
Do
- Water deeply and regularly for the first two years to establish roots.
- Maintain a large, mulch-covered, turf-free area around the base.
- Prune to develop a strong structure when the tree is young.
- Choose a planting site with enough space for its mature size.
Don't
- Do not plant in alkaline (high pH) soils, which causes nutrient deficiencies.
- Avoid wounding the thin bark with mowers or string trimmers.
- Don't fertilize a stressed or newly planted tree.
- Avoid planting near sidewalks or driveways where surface roots can cause damage.

Is Red Maple deer resistant?
Yes — Red Maple is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Red Maple bloom?
Red Maple typically blooms in early spring through mid-spring. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
