Hybrid Chestnut Planting Guide

Planting your new hybrid chestnut trees is simple! Follow these steps to give your trees the best start and ensure years of strong growth and nut production.

Care When Trees Arrive

• Unpack Immediately: Remove trees from the box as soon as possible.
• Keep Roots Moist: Never let roots dry out. Keep them in the original bag or wrap with damp paper/peat moss until planting.
• Short-Term Storage: Store in a cool, shaded place with roots moist but not waterlogged.
• Extended Delay: If planting is delayed more than a week, “heel in” trees by covering roots with moist soil or mulch.

Care While Planting

• Keep Roots Protected: Bare roots must remain cool, moist and protected from sunlight and wind throughout planting. Keep unplanted trees wrapped in damp packing material or covered with a wet towel.
• Brief Root Soak: If the roots need rehydration, soak them in clean water for one to two hours before planting. Do not leave bare-root trees submerged for extended periods.
• Plant One at a Time: Remove only one seedling from its protective covering when you are ready to place it in the planting hole.

Sunlight & Location

• Plant in full sun (6–8 hrs daily).
• Choose well-drained soil, avoid low/wet spots.
• Space 25–40 ft for nut production, 15–20 ft for wildlife plantings.

Pollination

• Chestnuts require cross-pollination for dependable nut production.
• Plant at least two genetically different chestnut seedlings, preferably within approximately 100 feet of one another.
• Seed-grown hybrid chestnuts are genetically different, but planting several trees improves pollination opportunities.
• Avoid relying on a single isolated chestnut tree for nut production.

Soil & Amendments

• Hybrid chestnuts perform best in well-drained, moderately acidic soil. A pH of approximately 5.5–6.5 is a useful target.
• Test the soil before applying lime or fertilizer. Make any needed corrections according to the soil-test recommendations.
• Backfill the planting hole with the original soil removed from it. Do not add compost, potting mix, peat moss, fertilizer or other concentrated amendments directly to the hole.
• In heavy clay, select the best-drained location available and dig the hole wider—not deeper—than the root system. Position the root collar at or slightly above the surrounding grade.
• Break apart large soil clods and roughen glazed hole walls so roots can enter the surrounding soil.
• Do not place gravel in the bottom of the hole or mix small amounts of sand into clay soil.
• If broader soil improvement is necessary, incorporate organic matter across the planting area rather than creating a small amended pocket around the tree.
  

Planting Steps

1. Dig a hole wide enough to spread the roots naturally without bending or circling them.
2. Make the hole only as deep as the root system. Keep the root collar at or slightly above the surrounding soil level.
3. If using a post-hole digger, do not loosen or dig soil below the required root depth. Loose soil beneath the tree can settle and cause the seedling to sink, leaving it planted too deeply.
4. Spread the roots outward and downward, trimming only broken or damaged root ends.
5. Backfill with the original soil, gently firming it around the roots to remove large air pockets.
6. Water thoroughly after planting. Do not mound soil against the trunk.

Watering & Fertilizer

• Water thoroughly immediately after planting to settle soil around the roots.
• During the first growing season, provide approximately one inch of water per week from rainfall or irrigation when the soil begins drying.
• Adjust watering for soil and weather. Sandy soil may require more frequent watering, while clay soil must be allowed to drain between applications.
• Keep the root area moist but never continuously saturated.
• Do not add fertilizer to the planting hole. Apply fertilizer or lime later only when indicated by a soil test.

Tree Tubes and Weed Control

• Use a properly installed 5-foot vented tree tube to protect the seedling from deer browse and rubbing.
• Secure the tube with a sturdy stake tall enough to support its full height.
• Install a weed mat or maintain a vegetation-free area around the seedling. Grass and weeds compete heavily for moisture and nutrients.
• Apply mulch two to three inches deep if desired, but keep it several inches away from the trunk.
• Inspect the tube and stake regularly. Correct leaning, replace broken ties and remove animal nests or debris when necessary.
• Remove or split the tube when the tree has developed adequate trunk strength and is above local browse pressure.

Pruning

• At planting, remove only broken, dead or badly damaged branches and root ends.
• Do not heavily prune a newly planted bare-root seedling.
• As the tree establishes, select one strong central leader and remove competing double leaders when necessary.
• Make clean cuts without leaving long stubs or cutting into the branch collar.
