How fast do oaks really grow
Oaks are generally considered moderate growers. Compared with willows or poplars they are slow, but a few species grow noticeably faster than slow oaks such as white oak. Under good conditions the faster oaks can add roughly 2 feet or more per year, while slower species may add a foot or less. Growth depends heavily on species, soil, water, sun and how well the tree was planted.
Fastest-growing oak species
These are commonly listed as the quicker oaks. Figures are approximate and drawn from typical nursery and extension descriptions.
- Northern red oak (Quercus rubra): often described as adding about 2 feet per year when young, reaching 60 to 75 feet. Very cold-hardy, with good red fall color.
- Pin oak (Quercus palustris): a fast-growing, pyramidal tree with drooping lower branches. It prefers acidic soil.
- Nuttall oak (Quercus nuttallii): grows quickly, tolerates wet soils and begins producing acorns earlier than many oaks. See trees for waterlogged and wet soil for other wet-tolerant choices.
- Shumard oak (Quercus shumardii): a large red oak popular in the South for shade and fall color.
- Southern live oak (Quercus virginiana): moderate to fast in warm climates once established, and very long-lived. It is only suitable for warm zones. See the growing zones guide.
- Monterrey oak (Quercus polymorpha): a warm-climate oak sometimes sold in Texas as a quicker shade choice.
Red oak group species generally outgrow those in the white oak group, which are slower but often longer lived.
How long to reach 20 feet
There is no single answer. A nursery tree planted at 6 to 8 feet that grows 1.5 to 2 feet a year could reach about 20 feet in roughly six to ten years. A slower species or a stressed tree may take a good deal longer. Expect the first one or two seasons to be spent mostly on root growth, with top growth picking up afterward.
What affects growth rate
- Species and genetics: the biggest factor.
- Sunlight: most oaks want six or more hours of direct sun.
- Soil and drainage: loose, well-drained soil with suitable pH supports roots.
- Water: consistent moisture while the tree establishes.
- Climate: a tree growing well within its hardiness zone grows better than one at the edge of its range.
- Competition: turf and weeds near the trunk can slow young trees.
How to help an oak grow faster
- Choose a species suited to your zone and soil.
- Plant in full sun with room for the mature size.
- Water deeply and regularly through the first two or three growing seasons.
- Mulch a few inches deep over the root zone, keeping it off the trunk.
- Avoid heavy fertilizing at planting. Test soil first and feed only if a deficiency is found.
- Prune only damaged or crossing branches in the early years.
Mistakes that slow growth
- Planting too deep: the root flare should be at or slightly above ground level.
- Overwatering: soggy soil starves roots of oxygen, especially once the tree is established.
- Wrong site: shade or crowding by buildings limits growth.
- Ignoring soil pH: pin oak in alkaline soil often yellows and struggles.
- Missing early warning signs: wilting, leaf discoloration and dieback deserve a prompt look from an arborist. Our guide to healthy vs unhealthy trees lists what to check.
Other fast-growing hardwoods
If an oak is still too slow for you, other hardwoods often listed as quick growers include red maple, tulip poplar and sycamore, though each has trade-offs such as weaker wood or messy litter. Faster growth often comes with a shorter life, while oaks tend to trade speed for strength and longevity. See how long oak trees live.
Wildlife that benefit from oaks
Oaks support a great many animals. Acorns feed deer, squirrels, jays, turkeys and woodpeckers, and oak foliage hosts many caterpillars that songbirds rely on to feed their young. The value grows as the tree matures.
Types of oak
Oaks belong to the genus Quercus, with hundreds of species worldwide. In North America they are usually sorted into the red oak group (pointed, bristle-tipped leaf lobes) and the white oak group (rounded lobes). Live oaks are a separate evergreen group found in warm regions. Pick a type that is native to your area and fits your zone.
