When to Transplant a Red Maple Seedling: Spring or Fall Only

No matter how small, a red maple (Acer rubrum) seedling should only be transplanted in spring or fall. Summer heat and inconsistent moisture cause transplant shock.

Best Practices for Success

Timing: Wait for cooler weather — early fall is ideal in New Brunswick.
Root Enhancement: Use a mycorrhizal inoculant (e.g., Plant Health Care's Tree Saver) to boost root establishment.
Fertilizer: Apply a low-salt fertilizer with <1% chlorine; follow label rates.

Why Not Summer?

Active growth + heat + disturbed roots = high failure rate. Dormant-season transplanting gives the tree its best start.
