How to germinate Juglans nigra seed:
Soak in very warm (not hot) water. Repeat 2x over 24 hrs. Small bubbles should effernese as nuts hydrate. Sow nuts 3 cm deep in a sowing layer consisting of equal parts peat, compost, & coarse sand. Use deep pots as this species puts down a very large tap root. Apply a thin top layer of fine mulch. Needs 90-120 days of cold stratification to germinate at 20 C in the spring/early summer. Alternate germination technique: baggie sow the nuts in a large clear plastic bag and mix nuts with just moist medium of equal parts coarse sand and peat. Check bag; pluck out sprouters as they emerge. Check bag often. We get better germination via baggie than direct or pot sowings. Use and secure protective ½” hardware cloth to protect nuts from rodents. The dang things will take emerged seedlings if there’s any nutmeat left in the shell. Guaranteed!
