Red Maple

The Red Maple, or Acer rubrum, is a legendary tree known for its brilliant scarlet autumn display and its ability to thrive in a wide variety of environments. When you receive these seeds, often called "keys" or "samaras," you are beginning a journey that could last a hundred years. However, Red Maple seeds can be tricky, with germination rates fluctuating between 50 and 60 percent. Success depends entirely on how you treat the seeds before they ever touch the soil. Most seeds you receive have entered a deep dormancy to survive the winter. To break this, you must first soak the seeds in warm water for 24 hours to rehydrate the internal embryo. Following the soak, they require "cold moist stratification." Place them in a container of damp peat moss or perlite and keep them in the refrigerator for about 60 to 90 days. During this time, the seeds may actually begin to sprout in the fridge; if they do, plant them immediately.

When the time comes to plant, usually in early spring, use a slightly acidic potting mix. Red Maples are sensitive to soil pH, and they prefer a range between 5.5 and 6.5. Plant the seeds about half an inch deep in individual pots. Keep the soil consistently moist but never drowning. Unlike many other trees, Red Maples can tolerate "wet feet," but young seedlings are still prone to damping-off fungus if there is no air movement. Place the pots in a spot with bright, indirect light. As the seedling grows into a small sapling, you will need to transition it gradually to full sun. The maintenance for a young maple involves consistent watering and a light application of balanced fertilizer in the spring. Protect the young trunk from rodents and deer, as the bark is sweet and tender in the first few years.

For container enthusiasts, Red Maples are a premier choice for bonsai or large patio specimens. If you plan to keep a maple in a pot long-term, you must use a container with excellent drainage and be prepared to prune the roots every two to three years to prevent the tree from becoming root-bound. Because of their stunning color, Red Maples are usually used as "specimen trees," meaning they are the focal point of a lawn or landscape. They provide excellent shade and look wonderful when surrounded by woodland plants like Japanese Forest Grass, Azaleas, and Ferns. The vibrant red of the maple leaves in October creates a breathtaking contrast against the deep greens of evergreens like Spruces or Fines if planted nearby.
