Growing Information:

Light: Kingnut Hickory prefers full sun to partial shade. It requires at least 6 hours of direct sunlight each day to grow well and produce a good nut crop. In shaded areas, the tree may grow slower and produce fewer nuts.

Soil: This species prefers well-draining, deep, fertile soils with a slightly acidic to neutral pH (6.0–7.5). It can tolerate a range of soil types, including loamy, sandy, and clay soils, as long as they are not waterlogged.

Planting Tips:

• Stratification (cold treatment) is recommended for Kingnut Hickory seeds. Soak the seeds for 24 hours and then refrigerate them in a moist medium (such as sand or peat moss) for 60–90 days to simulate winter conditions.
• Once stratified, plant the seeds 1–2 inches deep in well-draining soil. It’s essential to maintain a consistent level of moisture, but avoid over-watering, as the seeds will rot if the soil is too soggy.
• Kingnut Hickory trees grow slowly, so be patient during germination, which can take several weeks to months.
• Once the tree seedlings are large enough to handle, transplant them to their permanent site with plenty of space. These trees can grow quite large and need room to spread their roots and branches, so space them 30–40 feet apart.

Watering: Kingnut Hickory prefers consistently moist soil, especially during its early years of growth. Once established, the tree is more drought-tolerant but still benefits from regular watering during dry spells. Ensure that the soil drains well to prevent root rot.
