Pecan Germination:
1) Soak seeds in water and let them soak for 4 days. Be sure to change water daily.
2) Cold stratify by placing in a bag of wet peat moss or vermiculite. Cut a few small holes in the bag for air circulation and place inside the fridge for 90 days. Periodically check to ensure they stay slightly moist, but never overly wet.
3) Plant them in well draining potting soil between 1-2" inches deep.
4) Keep the soil very warm at 85 degrees with a heated propagator. Turning it off at night to create alternating temperatures will mimic their natural conditions and help with germination.
5) Expect staggered or erratic germination with seeds sprouting anywhere between 4-8 weeks.
