If you're looking for a natural privacy fence, you're likely asking how fast does a cedar tree grow so you can plan out your landscaping project without waiting decades for a bit of shade. The short answer is that most cedars are "moderate" growers, usually putting on anywhere from 12 to 24 inches a year. But honestly, it's not always that simple because "cedar" is a bit of a catch-all term for several different species that all behave a little differently.
Let's be real: nobody wants to plant a row of trees and wait until their kids are in college to finally stop seeing the neighbor's driveway. If you pick the right variety and give it what it needs, you can actually get a pretty decent screen going in just a few seasons.
Breaking down the growth rates by species
Not all cedars are created equal. If you go to a nursery and just grab "a cedar," you might end up with something that crawls along at six inches a year, or something that tries to take over your entire roofline.
Western Red Cedar
This is the heavyweight champion for many people. If you live in a cooler, damp climate (like the Pacific Northwest), these things are beasts. Under the right conditions, a Western Red Cedar can easily grow 2 feet per year. They're popular for hedging because they fill in thick and lush, creating a solid wall of green.
Eastern Red Cedar
Despite the name, this is actually a juniper, but we all call it a cedar anyway. These are tough as nails. They can handle droughts, road salt, and crappy soil that would kill most other trees. Growth-wise, they're a bit more conservative, usually averaging about 12 to 18 inches a year. They aren't the fastest, but they are probably the most "unkillable" option on the list.
Deodar Cedar
These are the ones with the slightly drooping, graceful branches that look like something out of a painting. They're beautiful, but they take their time. You're looking at maybe one foot of growth per year once they're established. They're more of a "specimen" tree than a "fast privacy screen" tree.
Green Giant Thuja
Okay, technically this is a hybrid, but it's often sold right alongside cedars because it looks and smells like one. If you are in a massive hurry, this is usually what people choose. These can grow 3 feet a year in their prime. If you want a wall yesterday, this is your best bet, though they lack some of the classic "cedar" charm and scent.
Why your cedar might be growing slower than expected
You'll see those growth stats on the tag at the garden center, but then you plant the tree and nothing happens for a year. That's totally normal. There's an old saying in gardening: "The first year they sleep, the second year they creep, and the third year they leap."
When you first put a cedar in the ground, it's going through transplant shock. It's focusing all its energy on fixing its roots rather than reaching for the sky. If your tree hasn't grown an inch in its first twelve months, don't panic. It's likely just getting its "feet" under it.
Soil quality is the next big factor. Cedars generally like slightly acidic, moist soil. If you've got heavy clay that stays soggy like a sponge, or sandy soil that dries out in twenty minutes, the tree is going to struggle. It'll spend its energy just trying to survive rather than adding height.
Can you actually speed things up?
While you can't force a tree to grow faster than its genetics allow, you can definitely make sure it hits its maximum potential. Most people accidentally "brake" their trees' growth without realizing it.
Watering is the big one. Cedars have relatively shallow root systems. They don't like to sit in a swamp, but they hate being bone-dry even more. During the first two years, you really need to be consistent. A deep soak once or twice a week is way better than a light sprinkle every day. If the soil a few inches down feels dry, give it a drink.
Mulching is your best friend. Putting a 3-inch layer of wood chips or bark around the base of the tree (but not touching the trunk!) does wonders. It keeps the roots cool, holds in moisture, and keeps weeds from stealing the tree's nutrients. It's probably the easiest thing you can do to help a cedar grow faster.
Fertilizer helps, but don't overdo it. A balanced, slow-release fertilizer in the early spring can give the tree the nitrogen it needs to push out new green growth. But if you dump a ton of chemicals on a young tree, you might actually burn the roots or cause it to grow too fast and spindly, which makes it floppy and prone to breaking in the wind.
The role of sunlight
It's a bit of a myth that cedars love the deep, dark forest. While many varieties are "shade tolerant," that doesn't mean they prefer it. If you plant a cedar in a spot that only gets two hours of sun a day, it's going to grow very slowly and probably look a bit "leggy" or thin.
For the fastest growth, most cedars want full sun to partial shade. At least six hours of direct sunlight is the sweet spot for that 2-foot-per-year pace. If they have to "reach" for the light, they might get tall quickly, but they won't be thick and bushy, which kind of defeats the purpose if you're looking for privacy.
Pruning for thickness vs. height
Sometimes people are afraid to prune because they think they're "cutting off" the growth they just waited for. But if you're growing a cedar hedge, light pruning is actually helpful.
By nipping the tips of the side branches, you encourage the tree to fill in the middle. A cedar that grows 2 feet tall but stays only 6 inches wide isn't a very good screen. Don't touch the "leader" (the main top stem) until the tree reaches the height you want, but feel free to tidy up the sides to keep it dense.
The "Long Game" of cedar growth
It's easy to get frustrated when you're staring at a 3-foot sapling and imagining a 15-foot wall. But the thing about cedars is that once they hit that "leap" phase around year three or four, they really take off.
Before you know it, you'll be the one out there with the hedge trimmers trying to slow them down. I've seen rows of Western Red Cedars go from "cute little shrubs" to "massive green wall" in what felt like the blink of an eye.
Final thoughts on cedar speed
So, how fast does a cedar tree grow? Expect about a foot or two a year once it's settled in. It's a marathon, not a sprint, but the result is a hardy, fragrant, and beautiful addition to your property that can last for a century.
Just remember to give them plenty of water in those first few years, keep the weeds away with some good mulch, and be patient during that first "sleeping" year. You'll be enjoying your private, evergreen oasis sooner than you think. And honestly, watching a tree you planted grow into a towering giant is one of the most satisfying parts of owning a piece of land.
