How to Plant a Black Walnut Tree from Seed

Black walnut trees are prized for their beautiful wood and delicious nuts. Growing one from seed can be a satisfying and rewarding experience. Here are the steps to do it successfully.

Gather the Seeds

The first step is to collect black walnut seeds. These can be found in the fall under mature trees. When the nuts fall to the ground, remove the husks, and wash the seeds. Dry them well and store them in a cool, dry place until ready for planting.

Preparing the Soil

Choose a spot with plenty of sunlight and well-draining soil. Remove any grass, weeds or debris from the planting area. Add organic matter such as compost or aged manure and mix it into the soil to provide nutrients for the seedling.

Sowing the Seeds

Plant the seeds in the fall, as soon as they are gathered. Dig a hole two to three inches deep and place the seed in the hole with the pointed end facing down. Cover it with soil and water thoroughly. Remember to mark the area where the seeds are planted, so you don’t accidentally disturb them during spring gardening.

Caring for the Seedlings

Keep the soil moist but not waterlogged. Mulch around the seedling to retain moisture and prevent competition from weeds. Protect the seedling from rabbits and other pests. Fertilize with a balanced fertilizer in the spring and again in the fall.

Transplanting the Seedlings

After the first year, the seedling will be about six to eight inches tall. At this point, it’s ready to be transplanted to its permanent location. Choose a spot with full sun and well-draining soil. Dig the hole large enough to accommodate the root ball of the seedling. Carefully remove the seedling from the ground, taking care not to damage the roots. Place it in the hole at the same depth as it was in its previous location. Fill in the hole with soil and tamp it down firmly. Water the seedling thoroughly.

Final Thoughts

It takes time and patience to grow a black walnut tree from seed, but it’s a rewarding experience. Black walnut trees can live up to 200 years and provide beauty and valuable timber for generations. As the seedling grows, be patient and continue to provide care and maintenance. Soon enough, you’ll have a mature tree that can provide delicious nuts and stunning wood.
