Answer: According to the American Horticultural Society's book, "Plant Propagation," buckeye seeds should be sown in midautumn. Gather ripe fruits when they fall, remove the husks, and sow at once. Or, store in moist peat at 37 degrees F, then sow in pots in late winter. Germination takes place at 50-59 degrees. Good luck with your buckeye tree!
