Oak Trees – Buying & Growing Guide

Although there are many types of oak trees around the world, with over 60 different types growing in just the U.S. alone. In terms of oak wood, it is usually categorized into two groups, red oak and white oak. Though you may think these would be easy to distinguish from one another, they have a lot in common in terms of aesthetics, and it can be hard to tell red from white purely at first glance. Read on to discover all about the different types of oak wood and how to care for your oak trees.

How to Grow Oak Trees

How to plant oak trees

Site your tree where it will have a great deal of room to grow, since oaks can grow to more than 100 feet. Choose a spot in full sun with well-draining soil, and dig a hole larger around than the pot the sapling comes in, and just as deep.

Unpot your seedling and shake out the roots. Tease them out or prune so they’re not circling the root ball. This will eventually strangle the tree and lead to poor growth. Place the tree in the hole; the juncture where the roots meet the trunk should be at ground level.

Backfill with soil, and tamp it down firmly. Water generously. For the first few weeks, water daily. Then reduce frequency to every two to three days for several weeks. Finally, adjust your watering to about an inch of water a week for the first year. After that, the plant should be fine without supplemental watering unless you are in severe drought conditions.

How to achieve maximum results

The oak tree genus, Quercus, is a large one and there are hundreds of oak tree varieties, some deciduous and others evergreen. For your particular tree, check the directions that come with the sapling on how to plant and care for your tree, or do some internet research to find out that variety’s native range. Your tree will perform best if you are able to reproduce its native setting as closely as possible.

How to Care for Oak Trees

Watering and nutrients

If you’ve planted your oak tree in fertile, well-drained soil, you should not need to do any supplemental watering after the first year unless your region is experiencing drought conditions. Western oak varieties are more drought-tolerant than Eastern varieties, however, which may require watering for the first several years. If your young tree has drooping leaves, lack of water may be the culprit.

Don’t fertilize your tree in its first year in the ground. After that, you may apply a fertilizer formulated for landscape trees in the early spring. Use a rotary spreader to apply the fertilizer out to the tree’s drip line. Consider adding an organic mulch near the trunk, such as shredded leaves, to add nutrients to the soil and keep weeds under control.

Pollination

Oaks are pollinated by the wind, which blows the yellow pollen from male to female flowers. The pollen is a ubiquitous part of late spring in areas with many oaks, and are a frequent cause of hay fever. Fertilized flowers mature into acorns, which drop from the trees in autumn and are a primary source of food for many animals.

Pruning

When your tree is young, prune for shape, and to eliminate broken or crossed branches. Mature trees require only occasional pruning, and this is best handled by a professional arborist. Don’t prune your oak during the summer months, as this is the time of year that a fatal disease called oak wilt is most active. Oak wilt is spread by beetles and other insects that feed on the sap running from pruning cuts. Prune only in early spring or late fall when these insects are dormant.

Pests and diseases

There are a number of pests that prey on oak trees, including the oak shothole leafminer, fall cankerworm, and forest tent caterpillar. Infestations on a mature oak tree may require the intervention of an arborist. On a younger tree, however, you may be able to control them with the application of a broad-spectrum insecticide.

In addition to oak wilt, oaks are susceptible to oak leaf blister, powdery mildew, oak anthracnose, and leaf spot. Trees with oak wilt should be culled immediately, as there is no treatment. Providing the appropriate water and nutrient requirements and siting your tree carefully will help it fend off pests and diseases, which is far preferable to having to treat them. If you suspect your tree is diseased, take a leaf or twig that shows damage to your local nursery to ensure you’re using the proper deterrent.

Main Differences Between White and Red Oak:

When buying an item made of oak wood, it’s important to understand whether it is made from white oak or red oak, because there are several differences between the two.

White oak tends to be more expensive than red oak, predominantly because it is denser than red oak and therefore results in a heavier, sturdier, and more long-lasting product.

White oak is less porous than red oak and more resistant to rot. For this reason, white oak is suitable for use in outdoor furniture or in items that need to hold up against water, such as in boat building. Red oak, on the other hand, should only be used for interiors and is popularly used for flooring and cabinet making.

Aesthetically, there is very minimal difference between red oak and white oak. The only giveaway, visually, is the rays, which differ in size. These ‘rays’ are small brown flecks, which look like tiny strips of thread running along with the grain of the wood. In red oak, these rays are shorter, and in white oak, they are longer.

Fun Facts about Oak Trees

Types of Oak Trees

The true red oak tree (Quercus rubra) is not necessarily the species your oak wood flooring or furniture will be made from when you select ‘red oak’ in a store. This is because there are many other types of oak trees that have similar characteristics to the red oak tree, and therefore they are grouped together under the heading of ‘red oak’ and used in its place.
