The Story
Plant Bio
Acer rubrum, or Red Maple, is one of the most common and widespread deciduous trees of eastern North America. It is known for its red flowers in early spring, red fruit, and brilliant red fall color. 'October Glory' is a popular female cultivar celebrated for its intense, long-lasting crimson-red fall color that develops later in the season than many other maples. It has a dense, rounded to oval crown.

Planting
How to Grow
- Select a site with full sun to part shade and moist, acidic soil
- Dig a hole twice as wide as the root ball
- Set the tree so the top of the root ball is level with the ground
- Backfill with the soil you removed, watering as you go
- Apply a 2-3 inch layer of mulch, avoiding the trunk
- Water deeply once or twice a week for the first year
Pro Tip
Plant in acidic soil for the most vibrant fall color; alkaline soils can lead to chlorosis and muted color.

Care Guide
Do
- Provide consistent moisture, especially in summer.
- Test soil pH if leaves appear yellow with green veins (chlorosis).
- Prune to remove crossing or dead branches in winter.
Don't
- Do not plant in dry or alkaline soils.
- Do not fertilize heavily, which can force weak growth.
- Do not pile mulch against the trunk, which can cause rot.
