The northern red oak tree is a tall, sturdy tree native to Eastern and central United States and southeast and south-central Canada. They were first introduced to Europe in the 1700s and are considered potentially invasive, so if planting outside of their native range, always plant with care. These trees need a minimum of 6 hours of direct sunlight every day in order to grow well, which puts them right on the borderline of part sun and full sun. Full sun is recommended, but you may make the cut if you don’t quite have full sun.
They don’t require special soil to grow. They can deal with a wide range of soils, ranging from acidic, clay, loamy, moist, sandy, and well-drained soils. Saplings can be planted outdoors in spring or fall in hardiness zones 3 through 8. If you opt to plant multiple trees, they should be spaced out by at least 10 feet. These trees grow very tall, up to 75 feet. They reach their maximum height after about 20 years of growth.
Young red oak trees can be provided a 12-4-8 or 12-6-6 NPK fertilizer to help their growth. These trees unfortunately are not suitable for containers and are not deer resistant. They produce a deep red, almost burgundy autumn foliage.

Planting northern red oak saplings
You can plant your red oak tree pretty much any time in the spring or fall. Planting the tree is straight forward. Simply dig a hole as deep as the root ball of the tree and twice as wide. Place your sapling in the hole and fill the widened section of the hole with a soil and compost mixture. Once the hole is completely filled, give it an extremely thorough watering, ensuring that the entire area is well watered. Use a bark mulch to help keep the roots cool and damp as it gets established. Routinely give a thorough watering until established.
Growing northern red oak trees in containers
Red oak trees are simply not suitable for growing in a container. They can grow to a very large size and will eventually become root bound and die, even if you’ve planted it in a very large container. If you want to grow a red oak in a container for a few years, that’s fine. But don’t expect it to live very many years or grow all that large.
Propagating northern red oak trees
If you want to plant your very own northern red oak tree, it’s as simple as collecting some acorns and planting them. Well, there’s a bit more to it than that. You can’t just plant an acorn and expect it to start growing right away. Acorns need to be stratified for at least 60 days before they will germinate. Stratification is the process of exposing it to cool temperatures.
You can mimic natural stratification by placing your acorns in a damp cloth in the refrigerator for 2 months. After 60 days, your acorn should be about ready to germinate and can be moved to a container of potting soil. It is highly recommended that you attempt to germinate at least 10 acorns as not all of them will be viable. Once ready, your sapling can be planted in the ground any time in the spring or fall.
