When to Plant Burr Oak Trees

Burr oak (Quercus macrocarpa) is a magnificent tree that can grow up to a height of 80-100 feet and has a spread of 70-80 feet. It is native to the central and eastern parts of North America and is known for its majestic presence and longevity. Burr oak trees are deciduous and produce acorns that provide food for wildlife, including squirrels, deer, and wild turkeys. For those interested in planting burr oak trees, it's important to know when the best time is to do so.

The Best Time to Plant Burr Oak Trees

Burr oak trees can be planted in either spring or fall. The best time, however, is in the fall, preferably between October and November. Planting in the fall allows the tree to establish its roots before winter, ensuring its survival in the following spring. During this time, the soil is still warm, which promotes root growth, and there is less risk of drought. Additionally, planting in the fall also means that there is less competition for resources like water and nutrients, giving the young tree a better chance to thrive.

Preparing the Site for Planting

The site where the burr oak is to be planted should be prepared well in advance. This includes removing any weeds, grass, or debris that might compete with the young tree for nutrients and water. The area should also be cleared of any rocks or other obstacles that might impede root growth.

Afterward, it's important to assess the soil type and pH levels in the planting area. Burr oak trees prefer acidic soils with a pH of between 4.5 and 6.5. The soil should also be well-drained, as burr oaks do not tolerate water-logged soils.

How to Plant Burr Oak Trees

Once the site has been prepared, it's time to plant the burr oak tree. To do so:

Dig a hole that is twice as wide as the root ball and slightly shallower than the depth of the root ball.

Place the tree's root ball in the hole, ensuring that the tree stands upright and is at the same level as it was in the container (if it was grown in one).

Fill the hole with soil, carefully tamping it down to remove any air pockets.

Water the tree until the soil is moist, but not water-logged.

Maintaining the Tree

After planting, it's important to maintain the burr oak tree to ensure that it grows well. This includes:

Watering the tree regularly, especially during the first year after planting.

Applying a layer of mulch around the tree to help retain moisture and suppress weeds.

Pruning the tree to remove dead, damaged, or diseased branches. This should be done during the dormant season (late fall or winter).

Fertilizing the tree with a slow-release fertilizer, preferably in the fall.

Conclusion

Planting a burr oak tree is a wonderful way to add a majestic and long-lived tree to your landscape. Planting in the fall is the best time to do so, and it's important to prepare the site, plant the tree correctly, and maintain it for optimal growth. With proper care, your burr oak can flourish and become a beautiful and enduring addition to your outdoor space.
