Hickory Tree Care: Tips and maintenance for healthy trees

Among the tallest and strongest of the trees to our native Georgia are hickory trees. However, they are also some of the most common problem trees that we get called about. If your hickory tree is doing well, here are some hickory tree care tips to help you keep your trees healthy and strong for years to come!

The broad strokes are:

In hickory tree care, prioritize well-drained soil, regular watering, and occasional fertilization. Monitoring for pests and diseases and pruning when necessary also play key roles in maintaining their health and longevity.

The following tips will apply to all the three main types of hickory tree we have in Georgia: the pignut hickory (carya glabra), shagbark hickory (carya ovata), and butternut hickory (carya cordiformis).

In this article, we'll break down suggestions for each of these points, and provide you with tips to care for your hickory trees for generations!

Unique requirements of hickory trees

Hickory trees are a wonderful addition to a property; shagbark hickory trees can produce nuts for up to 200-300 years! Caring for hickory trees has some distinct aspects compared to other trees:

• Soil Requirements: Hickory trees prefer well-drained, fertile soils. They do not thrive in compacted or poorly drained soils, unlike some other tree species that may be more tolerant of various soil conditions, like maple or oak trees. We recommend that if your yard or property struggles with drainage, you consider having a landscaper assist you with your drainage issues.
• Watering Needs: Hickories require consistent moisture, especially when young. In our area, for example, youth hickory trees can thrive around Lake Lanier, for example. However, they are also relatively drought-tolerant once established, unlike some trees that might need regular watering throughout their lives.
• Growth Rate: Hickories grow slowly, which means they need patience and long-term care. This contrasts with faster-growing species that might require more frequent pruning or other interventions. Grow and place your hickory trees with generational longevity in mind.
• Pest and Disease Management: While hickories are generally hardy, they can be susceptible to certain pests like the hickory bark beetle and diseases such as canker and powdery mildew. Care involves monitoring and possibly treating these issues, which might not be as problematic for other tree species.
• Nutrient Needs: Hickory trees benefit from a balanced fertilizer, particularly one rich in nitrogen. However, over-fertilization should be avoided to prevent excessive growth that can lead to weaker wood. We'll discuss more about fertilization further in this article.
• Mulching: Mulching is beneficial for hickory trees to retain moisture and protect the roots. This is similar to care for other trees but is particularly important for hickories due to their moisture requirements.

How to care for hickory trees on your property

If you live anywhere that hickory trees grow, you know these huge trees can be a perfect addition to a yard or property. To ensure your hickory trees thrive and reach their full potential, use the following tips:

Watering needs

As we discussed above, hickory trees require consistent moisture to establish their root systems. Water deeply once a week during dry periods. Mature hickories are relatively drought-tolerant but still benefit from occasional deep watering.

Avoid over-watering, as hickories do not tolerate waterlogged soils very well. Consider using a landscaper to install some drainage systems if this is an issue on your property.

Fertilization and soil care

Choose a nitrogen rich, balanced fertilizer. Apply fertilizer in early spring before new growth begins, or in the fall before the winter begins. Be cautious with the amount—over-fertilization can lead to excessive growth and weaker wood.

Test your soil periodically to ensure it remains fertile and amend it as needed.

Pruning and maintenance

Pruning hickory trees is essential for their health and shape. Remove any dead, diseased, or damaged branches. Prune in late winter or early spring before new growth starts.

Avoid heavy pruning, as hickories have a slow growth rate and can take time to recover. Consider consulting with a professional tree service in your area regarding which branches to prune, and which ones to leave.

Lastly, we suggest that you regularly inspect your tree for signs of pests or disease.

Pest and disease management

Hickory trees are generally hardy, but can be susceptible to certain pests and diseases. Watch for signs of hickory bark beetles, canker, and powdery mildew. Early detection and treatment can be the difference between a nuisance and a big job.

Use appropriate insecticides and fungicides as needed. Keep your tree healthy through proper watering, fertilization, and pruning to reduce the risk of pest infestations and disease.

Youth hickory tree care

If you're planning to plant new hickory trees, here are a couple of extra things to consider, since you'll have full control of the tree's location and surroundings:

Choosing the Right Location

Before planting, ensure your chosen location has:

• Good drainage and
• Ample space for the tree to grow (ensure that it's not directly under an obstruction, to avoid the tree interfering with power lines, structures, or canopies)

Hickories can grow quite large, so provide plenty of room for their expansive canopy and root system.

Planting Tips

When planting a hickory tree, dig a hole twice as wide and as deep as the root ball. Place the tree in the hole, ensuring the root collar is level with the ground.

Backfill with soil, water thoroughly, and apply a layer of mulch to retain moisture and protect the roots. Mulch is essential. It helps.

Long-term hickory tree care

Caring for a hickory tree requires patience. These trees are slow growing, but live for many years. Consistent care ensures they reach their full potential. Enjoy the process. Relish the rewards. Hickory trees provide shade, beauty, and delicious nuts that make the wait worthwhile!
