Kentucky Coffeetree, is a robust and striking deciduous tree known for its large, compound leaves and distinctive seed pods. Native to the central and eastern United States, this adaptable tree grows up to 60 feet tall with a similar spread, featuring a broad, open canopy that is desirable in spacious gardens and urban landscapes. Its deep root system helps to stabilize soil and prevent erosion, making it a valuable tree for both landscaping and improving soil health. The Kentucky Coffeetree has distinctive, large, compound leaves that provide a lush, green backdrop in summer, turning yellow in fall. Its bark is dark and furrowed, adding to its rugged charm. The tree produces large, bean-like seed pods, which, despite their name, are not used for making coffee but historically were roasted and ground as a substitute for coffee during the Great Depression. The tree's hardy nature and unique appearance make it a standout choice for those seeking an ornamental and functional addition to their landscape. Also Known As: Gymnocladus Dioicus, Kentucky Coffeetree, Coffeetree, Kentucky Coffee Tree, American Coffeetree, Kentucky Coffee-Tree, American Coffee Berry, Kentucky Mahogany, Nicker Tree, Stump Tree.

Do not eat treated seeds. **Seeds are freshly packed for the growing season of the year listed. Seeds are still viable beyond pack date. Store in a cool and dry location such as the refrigerator or basement to best preserve germination rates. Planting Instructions: Soil Preparation: Choose a clear, sunny location that is not in the shade of other trees and receives at least 6 hours of sunlight each day. Trees establish roots better in sandy, well-drained soils rather than heavy, poorly drained soil. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 6-8 inches deep. Loosening the soil will help the plant establish strong roots. If the soil is heavy or clay-like, mix in some sand or compost to improve drainage. Optionally, either form rows of soil beds or hills 4-6 inches high and at least 40 feet apart. This formation of ridges will help with drainage, ensure good airflow, and make harvesting or maintenance easier. Planting: Starting Indoors: Seeds do not require pre-treatment but would benefit from scarification. To scarify, cut or file through the hard seed coats using a file, sandpaper, or a knife to help water penetrate and encourage germination. After scarification, seeds should be ready to germinate. To germinate seeds, place seeds in moist sand or wrapped in a moist paper towel in bags in a warm 70F-90F area. Check every other day. Once roots are visible, sow in moist potting soil and place in a sunny area that is at least 65F, about 1 month after the last expected frost in spring. Keep the soil moist, allowing the top inch of soil to dry in between waterings. Once the seedlings have developed a few sets of leaves and are at least 6 inches in height, harden off seedlings then transplant outdoors in the spring, in a sunny location when temperatures are consistently above 65F. To transplant seedlings, prepare a transplant hole outdoors in a sunny, permanent location. Remove the plants carefully from the pots or flats and set them in the transplant holes, burying some of the stem in the ground. Pack the soil loosely around the plant and leave a slightly sunken area around each plant to hold water. Water the plants after transplanting. Directly Sowing: To germinate seeds, scarify seeds before planting in at least 65F soil. To plant, make holes 1 inch deep and spaced 40-50 feet apart down the rows of raised beds. Plant 1 seed per hole, then cover thinly with soil. Seedbeds can be covered with plastic film to promote germination. Water after planting. Planting Depth: 1 inch Within-Row Spacing: 40-50 feet Between-Row Spacing: 50 feet Care During the Season: Ensure Kentucky Coffee Tree receives plenty of sunlight, as it thrives in full sun to partial shade. Water the tree regularly, especially during dry spells, but be sure not to overwater, as it prefers well-draining soil. Once established, the Kentucky Coffee Tree is relatively drought-tolerant, making it a low-maintenance choice. Pruning is minimal, but you can remove any dead or damaged branches in late winter or early spring to maintain its shape and health. Fertilizing once a year in early spring with a balanced, slow-release fertilizer can help support healthy growth, while mulching around the base helps retain moisture and suppress weeds. Harvesting: Harvest Kentucky Coffee Tree seeds when the seed pods mature, which usually occurs in late fall. The pods will turn a dark brown and begin to split open when fully ripe. Carefully collect the pods from the tree or the ground, then crack them open to reveal the large, shiny seeds inside. The seeds are typically too tough to eat raw, so they should be roasted for a period of time to neutralize toxins before consumption. Once harvested and roasted, the seeds can be used for a variety of purposes, including as ornamental seeds or for making coffee-like beverages.
