Remove the Husk
Growing black walnuts from seed is not the best method of propagating the tree. The preferred method is simply transplanting young seedlings that emerge near the tree. However, germinating the seed can be a valuable project for teaching children about seeds and plant growth. With a little luck and care, you can harvest walnuts in the fall and start new trees in the spring. The process is simple but does require patience.
Instructions
1. Gather nuts in September or October as soon as they have fallen from the tree. Watch the tree carefully for signs of dropping nuts, as squirrels will quickly scurry away nuts before you can get to them.
2. Look for the largest and heaviest nuts. These have more kernel and produce stronger seedlings.
3. Soak the nuts in a container of tepid water to soften and remove the husk. Peel the husk away by hand. Wear protective clothing and gloves to prevent staining from the dye in the husk. Discard any nuts that float, as they are not viable seeds.
4. Place nuts in a plastic food storage bag with damp peat moss. Poke several holes in the bag to allow for air circulation. Store the bag in the refrigerator to 90 to 120 days. Walnuts require stratification and will not germinate until exposed to cold temperature for two to three months.
5. Check often for any signs of mold or mildew and keep the peat moss slightly damp. Open the bag to increase aeration if the contents appear too wet.
6. Plant in the spring in a sunny location. Cover the nuts with two inches of loose soil and water well. Keep the soil moist until sprouts appear. Walnuts generally have a germination rate of around 50 percent. Plant two nuts in each location to insure new seedlings.
