Growing Information:

Light: Kentucky Coffee Trees grow best in full sun, though they can tolerate partial shade. For optimal growth and development, ensure the tree receives at least 6 hours of direct sunlight per day.

Soil: This tree is adaptable to a wide range of soil types, including sandy, loamy, and clay soils. It prefers well-draining soil but can tolerate poor soil conditions once established. The tree can grow in slightly acidic to neutral soil with a pH of 6.0–7.5.

Planting Tips:

• To help break dormancy and improve germination rates, soak the seeds in warm water for 24–48 hours before planting.
• After soaking, plant the seeds about 1–2 inches deep in a well-draining seed-starting mix. Space the seeds at least 6 inches apart to allow for proper root growth.
• Keep the seeds in a warm, sunny location with temperatures between 70–75°F. Germination may take 3–6 weeks, so be patient.
• Once seedlings have developed strong roots and all danger of frost has passed, transplant them outdoors in their permanent location. Space the trees 25–40 feet apart, depending on your available space, to allow for mature growth.

Watering: Kentucky Coffee Trees are drought-tolerant once established but should be watered regularly during their first few growing seasons to establish a deep root system. After establishment, the tree is relatively low-maintenance and only requires watering during prolonged dry spells.
