Planting Instructions (From a Bareroot Tree into the Ground)

1. Choose the Location

• Select a permanent planting site with full sun and deep, well-drained soil.
• Allow plenty of room for the mature canopy and root system.
• Avoid planting near gardens or plants that are sensitive to juglone.

2. Prepare the Soil

• Loosen soil 18–24 inches deep and remove competing weeds or grass.
• Amend only if soil is extremely poor, as Black Walnut adapts well to most fertile soils.

3. Prepare the Bareroot Tree

• Soak the roots in water for 2–6 hours before planting.
• Remove any damaged or broken roots with clean pruning shears.

4. Dig the Hole

• Dig a hole wide enough to spread the roots naturally without bending.
• Make the hole slightly shallower than the root length so the root flare sits at or just above soil level.

5. Plant the Tree

• Spread the roots evenly throughout the hole.
• Backfill with the original soil, gently firming as you fill to eliminate air pockets.
• Keep the root flare visible at the finished soil surface.

6. Water Thoroughly

• Water deeply immediately after planting.
• Continue watering weekly during the first growing season when rainfall is insufficient.

7. Mulch

• Apply 2–4 inches of mulch around the tree, keeping it several inches away from the trunk.

8. Staking

• Stake only if planting in a windy location.
• Remove stakes after the first growing season.

Overwintering Eastern Black Walnut

Newly Planted Trees

• Apply a 2–4 inch layer of mulch around the root zone before winter.
• Water deeply before the ground freezes if autumn has been dry.
• Protect young trunks from rabbits, rodents, and deer with tree guards or protective wraps.

Established Trees

• Fully hardy throughout USDA Zones 4–9.
• Requires little winter care once established.
• Remove damaged or dead branches during late winter while the tree is dormant.

Winter Care Tips

• Avoid heavy pruning during periods of extreme cold.
• Keep mulch away from direct contact with the trunk to discourage rodents and reduce the risk of rot.
• Continue watering during prolonged winter dry spells in warmer climates if the ground is not frozen.

The Eastern Black Walnut is a magnificent native shade tree that offers generations of beauty, valuable hardwood, and flavorful nuts. Its stately form, impressive longevity, and exceptional wildlife value make it an outstanding choice for large landscapes, homesteads, woodlots, and conservation plantings where it can mature into a true legacy tree.
