    Try this if you may: Buy a metal garbage can, 32 gallon type with handles etc… Cut the bottom out of it and treat the plant like you would a running bamboo. The deep bottom is 32 inches high, if I remember, and should keep the plant in check and also not create a soggy bottom…which can and does cause them to rot and die back. But, remember that it is a native plant and belongs here…. Better this plant than Tree of Heaven. A friend just found a purple leaved one…variegated one may be next. Keep looking and keep planting natives. Don’t be afraid.

    Great article! Seeing as this was published in 1997, I was wondering how the metal-barrier enclosed sumac fared in your Cashew Family garden? Do you know if it ever escaped?

  • Gail Plummer August 6, 2018

    I have a sumac tree in the corner of my front yard. It is getting very bushy. Can I cut some of the branches down from the bottom to make it look more like a tree? What time of the year should I do this?

    Hi Sally, staghorn sumac (Rhus typhina ‘Laciniata’) is notoriously vigorous, spreading by suckers and underground roots. As a result, many gardeners despise it! To maintain this plant, you will need to continuously snip or dig out the suckers as it spreads. As the article describes, you can also use an underground barrier to try to contain it.

    I have a large stag-horn sumac that just appeared in my yard 15-20 years ago. I read that if you prune it it will sucker. I don’t touch it. I have suckers everywhere. I pinch off all growth on suckers. So I have sumac “sticks” everywhere that require constant pinching. Anything I can do to get rid of them? I love my large sumac volunteer.

    I just have one cone on my bush. Wondering how to transplant a root—nothing seem to work.

    How do I plant Rhus typhina, staghorn sumac, in a pot—size, soil, care,etc.?

  • Doreen Hughes October 22, 2015

    I live in England, where Rhus tyhina is common and considered a pest because of its suckering habit. However, in the same way that a “root collar” will restrict suckering and size, the reduced opportunities for the plant (even in a large pot) comparable to a “collar” will reduce its speed of growth and ultimate size. So if you don’t want a huge plant and are happy to cut out suckers, it will do well. Keep the pot up on “feet” to ensure good drainage, and be sure to always have at least one baby sucker in another pot, growing on, in case of failure.The cut leaf, or dissecta, variety does not usually grow so big, so it is often grown in very shallow pots as a bonsai tree, which makes me think it should do very well in a standard container.

    Is it possible to grow a staghorn sumac in a pot?

  • BBG Library Staff July 30, 2015

    Rhus species generally are susceptible to many pests and diseases, but none seriously. The decline in your otherwise healthy plant may be the result of a combination of cultural conditions: for instance, a period of drought followed by stress of added salt to the soil (fertilizer is salty). The roots may be having difficulty taking up nutrients; the suckers may be getting nutrients from their own roots. Try spreading a thin layer of compost on the soil surface around the sumac to improve the soil structure and make nutrients available. Water during times of drought. We recommend consulting a certified arborist who can assess the sumac and provide care for it. Visit New York Arborists and click on the tab “Find an Arborist.” You can also send a sample of your sumac to the Cornell Plant Disease Diagnostic Clinic for analysis.

    We have a mature (10yrs/20ft) sumac in a small manicured city garden. In previous years it has always had an abundance of leaf and fruit growth by June, but this year the leaves are dwarf in size, the fruit is growing but the leaves seem to have stop progressing to full leaf. There is also far more sucker activity than in previous years. Once in a while I fertilize the sumac. Could this be over-fertilization? I also used a weed killer on nearby paving, but suckers are now growing from in between those pave stones, so I doubt it was that.

  • Marilyn Rock June 14, 2015

    We have a 30-foot spread of staghorn sumac,  wour “natural fence.” A lot of it is 10 to 12 feet high, but we want it to be thicker and make a better blind. Is it best to prune it back in winter to the ground, or to 2 or 3 feet or so? We have a lot of little suckers in the patch, of variable size. We love it and want it to stay healthy, but we have never pruned it.  What is best?

  • Bob May 1, 2015

    I recently moved into a house with a 6-foot staghorn sumac. Its’ now spring and the tree looks healthy, but it has about 30 rust colored corncob-sized flowers from last year. Should I snip these off this spring to make room for new flowers?

  • Petula October 17, 2014

    I have moved into a new house, and to the front of my garden they have planted a little staghorn. The lower branch has lovely colorful leaves on it, but the higher two don’t seem to be growing at all. Is this common and will they grow eventually?

  • jblackburn July 16, 2014

    Sumac can usually tolerate severe pruning, so it very well may survive your nephew’s handiwork. The branches are naturally fuzzy, and if they start to develop new leaf buds, the plant should come back. Keep an eye out for new shoots coming up near the original plant’s base, which are also signs the sumac will recover. Make sure it has adequate water in the heat of the summer.

  • nancy hernandez July 13, 2014

    My nephew cut my plant down. Now the branches are fuzzy and it looks like it might be dying, but the branches are not drying up. I was wondering if the plant might be in shock or is it dying?

    I purchased a Rhus typhina ‘Laciniata’ in summer 2012. The tag claimed it “turns a beautiful orange and scarlet red in fall,” but a year later it is a light green in November in Minneapolis, and I am a little disappointed. The only thing it does not get is full sun, but it does get 7 to 8 hours of full sun a day. What can I do?

  • BBG Library Staff August 23, 2013

    Hi, Jo: Trees sometimes drop fruit naturally in order to prepare for a better fruit crop later in the season, but early fruit drop can also be a response to disease, drought, or waterlogging due to poor drainage. However, without any other evidence of disease or pest symptoms,  we can’t be sure why the fruit (called drupes) of your healthy sumac is dropping earlier in the season. 

    Sumac drupes this time of year are unripe and quite sour, so birds and other animals normally wait until late fall or winter to feast. In our urban environment, there is also the possibility of humans stripping the fruit if it is within reach.

  • jo farrington July 30, 2013

    My staghorn was looking really healthy and formed cones, which were light in color. This morning I noticed the little seeds on the cones are rapidly dropping off, leaving just the skeletal stem-like twigs that supported the seeds. Does anyone have any idea what is going wrong here?

  • Karen June 22, 2013

    We have had a staghorn sumac in our backyard landscape for 12 years, beautiful and thriving here in Pennsylvania.  LIke Patty said, this year the tree looks like it is dying. The leaves that have formed are all wilted, though there are plenty of healthy looking suckers all over the yard. I would really like to save it somehow as it is in a perfect spot and looks great covered in snow in the winter. If I cut it back to the ground, will it regrow?

  • BBG Library Staff June 13, 2013

    Hi, Deb: The following sumacs grow in Zone 3 (linked to descriptions by the Missouri Botanical Garden):
    Rhus glabra, Rhus typhina, and Rhus aromatica (which has less showy seedpods than R. typhina and R. glabra.

  • Nicole June 8, 2013

    I bought a cutleaf sumac last summer. I ended up putting it into a large container last summer but moved it into the garden this spring, feeling very hopeful to see little leaf buds sprouting from the wood. The container seemed very moist when I removed, a detail that worried me a little. It is now in a sandy, well-drained area with 3 to 4 hours of full sun. Now, in early June, the buds, (still very alive) have not grown even the teeniest little bit. It’s like it has stopped growing as it looks the same as it did over a month ago. What should I do, and what is wrong with it?

  • Patty June 6, 2013

    My large, treelike staghorn sumac has been beautiful for several years. I keep the suckers out as it is my focal specimen in the perennial rock garden. But so far it’s not leafing out at all and the number of suckers is more than in previous years. Do they just get to a point where they stop growing? We’re in SW Colorado…Zone 3/4 and we had a less-than-normal snowfall and no rain this spring. I hate to cut it down. Any hope just getting the suckers out? Any suggestions?

  • deb girardi April 27, 2013

    I am looking for a sumac that can survive winter at Crowsnest Pass in the Canadian Rockies. I believe this is in Zone 3. I do want something that will give a good display of candles. Can you help me?

  • BBG Staff October 26, 2012

    We are not sure what is causing the problem with your staghorn sumac. Since the sumac, a root-prolific plant, is in a container, drainage may be an issue. If the soil has become soggy in the bottom of the container, the plant may have root rot to some degree, causing the dieback. You may wish to monitor the moisture level at the bottom of the container or repot to improve drainage. (On the other hand, drought is a common cause of plants losing leaves earlier in the season than usual.)  Another set of symptoms to look for: drooping leaf stems, yellow patches on leaves changing to brown, and discoloring of interior stems. This suggests verticillium wilt, a common occurrence during cooler weather. It is not curable, but transplanting to a container with sterile soil may help. If the skin of the sumac has been damaged, you may notice a sticky substance on the stems. Wounds to the skin of the sumac often promote the suckers with which the plant in times of stress repropagates itself. You may wish to use a sucker to start a new plant.

    I have a golden cutleaf sumac. Its one of my favourites. My question is, when I planted it last summer (2011),  it looked fine, but now I have two pretty large suckers on the ground. Can they take the life from the tree? The tree looks like it is dying, but the suckers are beautiful. I would appreciate any comments you might have. Thank you.

  • Julie Pezzetti September 27, 2012

    I purchased a cutleaf staghorn sumac and loved it. It seemed to thrive at first, then when the summer got hot, the leaves started to shrivel and die. There are very few leaves left on the tree at this time. I have it in a large container. It’s about 2.5 feet tall at this time; branches and bark seem to be okay— just the leaves keep drying. I water it regularly and really don’t want to lose it. What can be the problem?

  • josina smith April 2, 2012

    Do I remove the old cones when I prune my sumac tree?
