We’re back in the garden, and this time we’re pruning our smoke tree… again! You may remember that we originally tried this last year, with disastrous results. Well, now we’re changing up our landscaping techniques and hoping that this second time will be a charm.
What is a smoke tree? It’s a colorful ornamental plant (genus name: Cotinus) that gets its common name from unique billowy flower clusters that appear in spring and resemble puffs of smoke. There are several smoke tree varieties (Royal Purple, Velvet Cloak, Grace, Golden Spirit and more), with deciduous leaves that vary from green to deep red to dark purple, depending on the season and species. Often used as a prominent accent in the garden because of its brilliant colors and unusual flowers, this plant can range in size from 8 to 30 feet in height, and it’s drought- and cold-tolerant. In other words, it’s very hardy and it grows fast! We’re not sure what variety ours is – John is thinking Royal Purple, but I’m leaning more toward Grace.
Last year, we planned to trim down our smoke tree to make it smaller and more contained than before. We talked about our subsequent pruning attempt (and failure) in this post, but basically we pruned it at the wrong time of year (mid-winter) and in the wrong spots (we cut the branches at their ends, instead of at the branch collars). This caused the tree’s branches to skyrocket once the weather turned warm, rather than grow into the tidy compact shrub we were hoping for.
Our goal – a cute little smoke tree underneath our dining nook window – was figuratively buried under the smoky monster that grew over and completely obliterated our backyard garden view. I mean, who needs curtains when you’ve got giant overgrown leafy branches?
And by autumn, the tree branches had grown all the way to the roof line. While the bright reddish-orange color was really beautiful, the tree totally obscured our ornamental cherry tree and little Japanese maple. (Can’t see them in the photos below? That’s my point! They’re hiding next to the stairs on the left.)
So, obviously not the results we were hoping for when we first pruned the smoke tree. And once the summer growing season was in full swing, any further pruning would just spur more growth, so we had no choice but to sit on our hands and wait. In the meantime, we did some more smoke tree pruning research (see our sources at the end of this post), and that’s when we started to consider rejuvenating the smoke tree by cutting it almost all the way to the ground. In theory this pruning method will encourage a smaller bushy plant instead of the taller splayed tree we’ve had for the past couple of years. Ideally, we’d like to end up with something about this size:

Fast-forward (through a long snowy Midwest winter) to a few weeks ago. With the plant still dormant in the chilly late-winter weather, John gave our new smoke-tree-to-bush pruning method a try. He started by trimming off the numerous small upper branches with long-handled loppers.
As he worked his way down the tree, he switched to a bow saw to cut through the thicker branches. (While he’s used this versatile tool on a variety of projects over the last 20 years, a more common saw for pruning is a folding saw like this one – it’s better for maneuvering around dense branch growth and conveniently folds up in your pocket when not in use.)
The previous owner had tied the smoke tree to a wooden trellis staked into the ground, to support it as it grew. But when John started removing the ties to take out the trellis, we realized that it had already been pulled out of the soil by the tree’s overgrown strength. It was literally hanging on by a thread!
After detaching the trellis, John revved up his trusty chainsaw to cut the main trunks of the smoke tree (the same way he sawed through our giant yew bushes last summer).
This is what we were left with when it was all over.
And our view to the backyard is much improved!
Now we just have to wait and see how things grow back this summer. According to our research, smoke trees usually experience a rapid growth rate after pruning (and we found that out firsthand last year) – up to 6 feet or more in height! But while the leaves will be bigger and more colorful than before, the signature “smoke” flowers may not appear until the following year.
It’s hard to imagine that this plant could go from 2-inch stumps to 6-foot-tall branches in one growing season, but we amateur gardeners are definitely intrigued – and hope we pruned it right this time. We’ll keep you posted on the progress!

What do you think – did we prune the smoke tree too much? Will it grow back, or will we be left with a big empty space in the garden this summer?
