Red Oak Tree Characteristics and Info

Red oak is a hardy tree suitable for growing in USDA plant hardiness zones 3 through 8. This moderately fast-growing oak tree reaches mature heights of 60 to 75 feet, with a spread of 45 to 50 feet. The tree is valued for its deep root system, which makes it useful for planting near urban streets and sidewalks.

How to Grow a Red Oak Tree

Planting a red oak tree is best done in spring or fall so the roots have time to settle in before the arrival of hot, dry weather. Select a planting space carefully so the tree won’t interfere with buildings or power lines. As a general rule, allow at least 20 feet in each direction. Ensure the tree is exposed to at least six hours of direct sunlight every day. Microbes In Soil: How Dirt Makes You Happy In its natural environment, red oak has a symbiotic relationship with various fungi, which provides the roots with moisture and minerals. The best way to replicate this natural soil environment is to dig generous amounts of manure and compost into the soil before planting. This step is especially important in urban areas where the soil may be depleted. Plant the tree in a hole at least twice as wide as the root ball, then fill the hole with a soil/compost mixture. Water the tree deeply and slowly to ensure the area around the root ball is saturated. A thick layer of bark mulch will keep the roots cool and moist. Protect young trees with a fence or cage if you have hungry rabbits or deer in the neighborhood.

Care

Care these trees is minimal, but a new tree requires regular moisture, especially during hot, dry weather. Water the tree deeply once every week in the absence of rainfall. Established trees are relatively drought tolerant. Treat young trees with a commercial fungicide if you notice powdery mildew during warm, humid weather. Watch for aphids, which are usually easy to remove by spraying the foliage with a strong stream of water. Otherwise, use an insecticidal soap spray.
