Crepe Myrtle Pruning Step-by-Step

February 24, 2009 | By | Comments (853)

What concerns people most in the country right now? Losing their jobs? Losing their retirements? Nope. It’s how to properly prune their crepe myrtles Here’s a step-by-step guide showing how the Grumps prunes his.


Why do you need my advice? Because a lot of you take guidance from your ignorant neighbors neighbors, who prune their crepe myrtles to look like this.


This is what I call “crepe murder.” I didn’t invent the term. I think it was coined by Byers Nursery, a big wholesale grower of crepe myrtles in Huntsville, Alabama. I just did what we Americans have always done so well — pass off other’s good ideas as your own.

Crepe murder is bad for several reasons.

1. It turns beautiful trees into ugly stumps.

2. It prevents the formation of pretty, mottled bark on maturing trunks.

3. A forest of skinny, whip-like shoots sprouts from the end of each ugly stump. These whips are too weak to hold up the flowers, so the branches often bend to the ground, like a drunk who’s about to lose his lunch.

Another reason people butcher crepe myrtles is because they say their plants get too big. All that this means is that these cretins chose the wrong plant for the wrong spot. Most popular crepe myrtle varieties (‘Natchez,’ ‘Miami,’ ‘Sioux,’ ‘Dynamite,’ Muskogee,’ ‘Watermelon Red’) grow at least 25-30 feet tall. So plant them out in the yard — not in front of your bay windows. Or go for compact, lower-growing kinds, like ‘Acoma,’ ‘Centennial,’ ‘Hopi,’ ‘Prairie Lace,’ ‘Victor,’ ‘Zuni,’ of the Petite Series from Monrovia.


The crepe myrtle you see above is deep-pink ‘Miami.’ I planted it in my front yard from a 3-gallon pot 15 years ago. I never pruned it much, because I strung it with tiny Xmas lights that I never took down. Leaving them on the tree reduced my Xmas decorating each year to 10 seconds. All I had to do was plug in the lights before Xmas and unplug them after. You could learn from this.

However, not being able to prune without cutting the light cords meant my crepe myrtle grew too dense and spread too wide. So last week, I took off the lights. Then, aided by my lovely unseen wife who agreed to take pictures, I finally pruned it to show you how it’s done and how a mature crepe myrtle is supposed to look. Murderers, take note!

Here is the crepe myrtle before I started. It doesn’t look too bad, but needs thinning. The tool leaning up against it is my trusty pole pruner. I like it because you can extend the pole to cut branches more than 15 feet from the ground.

Crepe Myrtle — Your Questions Answered


Before you prune anything, it’s a good idea to know what you’re trying to accomplish. After all, you can always go back and cut more. You can’t go back and cut less. My objective was to maintain well-spaced, main trunks with handsome bark and to thin out out the center to permit easy penetration of sunlight and air. I always say if a bird can easily fly through the center of your crepe myrtle, the branches are spaced about right. If a bird can easily fly through the center of your house, you’re probably missing some windows.

Pruning Tools

To properly prune a mature crepe myrtle, you need 3 tools.

1. Hand pruners to clip twigs and branches less than 1/2-inch thick.

2. Loppers to cut branches 1/2-inch to 1-1/2 inches thick

3. Pole pruners or a pruning saw to cut branches more than 1-1/2 inches thick.

When to Cut
Late winter (right now) is the best time to prune a crepe myrtle, because it’s leafless and you can easily see all of the branches. It also blooms on new growth, so pruning now won’t reduce blooming. In fact, it may increase it.

What to Cut

Remove branches in the following order.

1. Suckers coming up from the base.

2. All side branches growing from the main trunks up to a height of at least 4 feet.

3. All higher branches growing inward towards the center of the tree.

4. All crossing, rubbing, and dead branches.

5. Branches growing at awkward angles that detract from the tree’s appearance.

Always cut back to a larger branch of the trunk. Don’t leave stubs. Removing seedheads on the end of branches is optional. Leaving them doesn’t reduce blooming. I leave mine.


The Finished Product
Below is the result of this year’s pruning. Isn’t it purty? The crepe myrtle is still a little denser than I would like, but I can prune it again next winter. Every year, the job gets easier.

    I have 2 CM next to my house, they are 10 years old and about 15 or more feet tall. about 5 feet or so from house. How do I tell what type they are? I don’t want them to damage my foundation….I’ve never murdered them, well until last week when I lopped off two branches… Will reconsider cutting the rest. Should I have them removed to spare my foundations?

    Help! Once the 2 feet of snow cleared with todays rain, we discovered that some inner trunks of my beautiful 10 year old crepe myrtle have broken at about 4 feet from the ground (the rest had grown to around 15 feet high…..any advice?

    I have 8 dwarf crape myrtles as a border, I think they are red razzle dazzle but I;m not sure. They vary in height. I fertilize in the spring and they are mulched. I have never pruned them. They are not filled out and healthy looking like a lot I’ve seen. I don’t know what I am doing wrong. I live in North Carolina so climate should not be a problem. Can you tell me how to get them to grow fuller and to look healthier?

    Have no fear! Your crepe myrtle will grow back quickly! I don’t like the idea of the severe pruning, though. Can you move them so that they won’t interfere with the lines?

    I copied what my neighbor did a few years ago when he pruned his crepes. But his trees had thick trunk /branches from the ground up. He cut them at about three or four feet off the ground and they grew back very nicely. The two I have were skinny trunks that didn’t sprout until five or even six feet off the ground. They were going up instead of out and even making contact with the power lines. I just cut them off at knee length and fear I may have gone too far. Two stumps is what I have now. Will they revive and flourish?

    Thanks for the step-by-step guide! I just moved into my first home which has a crepe myrtle in the front of my home. It’s grown pretty high, so I was going to prune it a bit. My realtor suggested the “crepe murder” when I expressed concerns about it growing above the roof. I’m glad I looked this up before I followed her advice!

    I’d prune them the way you describe, cutting them back to where they meet another branch or the trunk.

    February 1, 2013 at 12:29 pm
  11. Steve Bender

    Are both crepe myrtles the same kind? Hope so — otherwise they will always look different. In any case, you might try pruning the taller one to match the height of the other. Hopefully, this will produce fuller growth.

    Winter, spring, and fall are good times to transplant.

    In the next few years, trim these new branches to grow up and out. Remove any side branches that grow inward towards the center of the tree.

    We are at least five years overdue on pruning a fairly mature crepe myrtle. I have two branches on a couple of main trunks that now extend at least five feet above the rest of the canopy. The rest of the branches and foliage are fairly thick and could possibly conceal if these were cut out. Do I let mother nature take its course and let them grow toward the sky outpacing their brethren, or do I cut them back to the dividing point on the trunk?

    I have two crepe myrtles on either side of my drive way, they don’t look like they’ve ever been murdered but the branches/leaves/blooms are very sparse. They also look very dissimilar in shape. One has a single trunk and the other has 3. I would like to prune them to have a more symmetrical look up top. What is the right amount of pruning that would create more fullness and shorten one that is very tall?

    Like Margaret my crepes have had 19 years of being murdered. Mine has the big knots, bigger then two fists. I’m planning on cutting off the knots and then follow your directions but can you leave say two or three branches once they start coming out this Spring? Then what do you do the following year if anything.

    It seems that new crepe myrtles come along about once every 15 minutes. I’m not familiar with ‘Lacy,’ but I’m sure I will be soon.

    I do not think the “weed” on your crepe myrtles is a weed at all, but a harmless plant called a lichen. It uses the trunks and branches solely for support and does not steal water or food from the tree. The reason you see so much of it is that it needs sun and sparsely branched or unhealthy trees let in more sun. Instead of committing crepe murder, I suggest removing any dead branches now, cutting them back to the trunk or where they meet other branches (don’t leave stubs). To determine if a branch is dead, scratch the bark. If you see green underneath, the branch is alive. If you see brown, the branch is dead. Then fertilize your crepe myrtles this spring with a tree/shrub fertilizer at the rate specified on the label.

    We just moved into an older home with 3 crepe myrtles. They are very tall and ragged and all 3 of them have a weed of some sort growing on the branches. They barely bloom any flowers because of all the “weed” I’m able to pull of the weed but it releases a powder. I’m guessing it’s a fungus but in order ot get rid of it I may need to commit crepe murder. Any advice?

    January 21, 2013 at 3:54 pm
  25. Steve Bender

    Katie & Tina,

    Branches should not be allowed to touch the house, so feel free to shorten those. I have a tall crepe myrtle in front of my house. I have removed all the side branches on the main trunks growing towards the house and train the plant to grow basically upright and out towards the lawn. The black mold is a fungus that grows on sweet, sticky honeydew secreted by feeding aphids. If you kill the aphids, you won’t have the mold. Try spraying your plants in early summer according to label directions with horticultural oil. Be sure to wet the undersides of the leaves as well as the tops.

    Mr. Bender I am sooo glad I came across your advice on crepe myrtle pruning I have 5 of them, I bought them at the end of season and they were very small but affordable, I havent
    pruned them in the four years they have been growing. My neighbor has murdered his every year I almost followed in his footsteps thank-you for saving me !!!!

    Hi. We have 3 giant beautiful pink crepe myrtles next to our house. They are touch the roof line. We don’t want to dig them up but want to cut a bit of the tops off. I know this is a no no but was is the alternative? They have a beautiful shape and bark. And our crepe myrtles in front of our house get a black mold on them. What can we do about that? It happens every year. Thanks.

    You can do this!!!!!

    Your crepe has officially been murdered. But don’t despair. If you prune it from now on the way I describe above, it will regain its beauty and bloom just fine.

    Yes, you can prune your crepes the way you describe. It’s never good to let any branch touch the house. The canopies will grow back quickly.

    Thank you so much for this article. We just bought a house with 4 mature crepe myrtles that have been well cared for and have a lovely natural shape. One, however, touches the house and another is a bit younger and smaller. Is it ok to cut them back all to the same approximate height and let them grow back through the spring? My husband worries that the canopy won’t come back.

    Three feet from the house is way too close if you have crepe myrtles like ‘Natchez’ that grow 30 feet tall. I would definitely try to move them to where they have more room and won’t impact the house. It’ll be a big job, but you can do it now. You can cut them back before you dig to make the job easier. Just don’t murder them after they’ve been transplanted.

    Hate to say it but I much prefer the crepe murder look! I tried it the other way and for years my crepe myrtle looked leggy and unhealthy. I was going to cut it down thinking it was just too old and cut the limbs way back to look like your picture and WOW! It made a nice big bushy, colorful tree. I hadn’t seen that in 15 years!

    I bought a house that’s 15 years old, and former owners planted four crepe myrtles about 3 feet from the side of the house. They are so large that I’m not sure if they are able to be saved if I have someone come to remove. I’d love to replant in the back yard if possible. Any advice is welcome.

    Only follow the instructions for Margaret if you’ve already murdered your plant and created knots. Otherwise, leave it pretty much alone. Miniature crepes need little pruning, other than to remove dead wood and thin out the centers a little bit.


    Your discriminating tastes are of the highest order!

    Steve – great advice and guidance. Pruned this morning and am confident of result. Others had lopped them off over the years, but the airing out (thinning) and eliminating cross branches looks like I might get a more vertical result in the spring.

    Cut off the knots now. Next spring, lots of shoots will sprout from the ends of the cut branches. Select one to let grow from each and then cut off all of the others. Keep this up and in a few years, you won’t be able to tell where the knots were.

    Assuming you don’t have a dwarf crepe myrtle, what you do is prune off all side branches coming from 3-4 trunks up to a height of 4 feet or so. You can do this now. Then just let the top grow.

  50. Steve Bender

    What you’re digging up aren’t really volunteers, but suckers growing from the big crepe myrtle. Suckers usually grow after the roots have been damaged. That’s why it’s a good idea to avoid cutting the roots of a crepe myrtle. If I were you, I’d just cut off the suckers as they appear. If there are no more injuries, they’ll decrease in number over time.
