How to plant staghorn sumac
- Favor a sunny spot, and don’t worry about the soil type: it’s not an important criteria.
- Water well after planting.
- Staghorn sumac grows extremely fast, make sure you’ve given it enough space to spread out.
- Follow our advice on planting shrubs
Propagation through root cuttings in fall, but you can also just wait for it to send shoots up from the running roots and dig those out.
Pruning staghorn sumac
- Pruning actually isn’t a requirement.
- If you wish to reshape your sumac or balance the branches somewhat, prune in fall.
- Eliminate suckers and shoots that pop up out of the soil as soon as you notice them. This will help you control the shrub and keep it from spreading too much.
Staghorn sumac has rather brittle wood that can’t cope very well with windstorms. Don’t even think of hanging a swingset from it.
Can I cut staghorn sumac back by a lot?
Staghorn sumac will bounce back from even the hardest pruning. If you cut it down to a stump, new shoots will reappear in the following spring from the vigorous root system. It’s as strong a grower as bay in this respect.
Hatracking, or cutting back haphazardly just to shorten the tree, is strongly discouraged. Indeed, new branches would come out that are only weakly connected to the tree. Since staghorn sumac wood is brittle, these branches would easily break off if it gets windy. Dangerous if people walk nearby. Not a problem if you contain growth to less than 6-8 feet (2-2.5 meters).
That being said, it’s best to simply shorten the longest branches by cutting them back to a junction. For example, if a branch splits into two smaller branches, cut the longest of the two back to the junction. If the tree still feels too large, go for a second round. Best do this in fall, after leaves have fallen.

Is staghorn sumac poisonous?
While very common, staghorn sumac isn’t dangerous to most people. Other species that share common ancestors, like poison sumac (Toxicodendron vernix, formerly Rhus vernix) and the Chinese lacquer tree (Toxicodendron vernicifluum, formerly Rhus vernicifera) are very poisonous for most humans and pets. For those two, the entire plant is poisonous, as the sap is what contains the toxic compounds.
However, especially after repeated contact, some people turn out to be vulnerable to staghorn sumac’s sap.
Too much exposure to that white, milky sap called latex might trigger an allergic reaction.
This usually isn’t anything more than dermatosis, rashes or swelling on the hands and forearms, but in some cases it may lead to severe anaphylactic shock, where the blood pressure drops to the point of losing consciousness and swelling of tissues in the throat and mouth area can lead to choking.
