How to grow it
PLANTING: Open your Seeds In A Cup kit and fill the container with the provided growing medium. Plant seeds ¼ inch deep. Water gently until evenly moist. No stratification needed — American Elm seeds germinate readily. Place in a warm, bright location (65-75°F) or under a grow light for 14-16 hours/day.
GERMINATION CARE: Keep soil consistently moist. Elm seeds germinate rapidly — expect sprouts within 7-14 days. Ensure seedlings receive ample light to prevent leggy growth. Thin to the strongest seedling if multiple emerge in the same cup.
SEEDLING CARE: Elm seedlings grow fast. When seedlings reach 4-6 inches tall with several sets of true leaves, transplant to a larger pot. Move outdoors in USDA Zones 2-9 after last frost, choosing a full-sun location. Water deeply once weekly. Growth of 2-3 feet per year is normal. Prune to maintain the classic vase shape as the tree matures.
