Siberian Elm Problems: Remove It or Keep It?
If seedlings are sprouting in every rock bed and crack in your driveway, there’s probably a Siberian elm nearby. It grows fast and takes almost anything, which is why it’s everywhere in Las Cruces. It also breaks in storms, spreads by the billions, and resprouts when you cut it. Here’s how to deal with one.

Quick answer
Should I remove a Siberian elm in Las Cruces?
Usually, yes, if it’s young, weak or near the house, walls or power lines. Siberian elm is a Class C noxious weed in New Mexico, with weak wood, huge spring seed crops and roots that lift walls. A healthy, well-placed shade elm can sometimes stay.
If you keep one, prune out weak limbs and pull seedlings every spring. If you remove it, treat the stump right away or it will resprout.

Problems
Why are Siberian elms a problem?
They grow fast but don’t age well. NMSU notes branch breakage is common, they produce a huge crop of seeds every spring that outcompete better plants, seedlings grow long taproots, roots can uproot yard walls, and elm leaf beetles chew holes in the leaves.
Do Siberian elms break easily?
Yes. Weak, brittle wood and narrow branch angles make them prone to splitting in monsoon and spring winds.
Can elm roots damage walls?
They can. Roots and suckers can lift block walls, sidewalks and patios near the tree.
What are the holes in the leaves?
Likely elm leaf beetles. The damage is mostly cosmetic, but heavily chewed trees look ragged by summer.
Problems summarized from NMSU Southwest Yard & Garden (Thompson, with Beck), July 2020, and the New Mexico noxious weed list, where Siberian elm is Class C.
Seedlings
How do I stop Siberian elm seedlings?
Pull them as soon as you see them, ideally in their first season before the taproot gets long. Keep rock beds covered with permeable weed barrier and 2 to 3 inches of rock, apply pre-emergent in late winter, and sweep up seeds in spring.
1
Pull early
First-year seedlings pull out easily; older ones need digging.
2
Get the root
Seedling taproots can be longer than the top. Loosen the soil and pull straight up.
3
Sweep seeds
Rake or blow the papery seeds out of beds and gutters in spring.
4
Cover bare ground
Weed barrier and rock stop most seeds from rooting.
5
Pre-emergent
Apply in late winter to reduce the spring flush.
Removal
How do I remove a Siberian elm so it doesn’t grow back?
Cut the tree and treat the fresh stump right away with a labeled systemic herbicide, ideally within minutes, then grind the stump. Watch for suckers from the roots for a season or two and cut or treat them as they appear.

Keep it?
Can I keep a Siberian elm safely?
A mature elm that’s healthy, well away from the house, and giving shade you depend on can stay if it’s pruned regularly. Remove dead and weak limbs, thin the canopy before monsoon season, and pull seedlings and suckers every spring.
How often should it be pruned?
Check it every year and thin before monsoon season. Remove limbs with cracks or narrow, weak angles.
When should it come out?
When it’s declining, has major cracks or decay, overhangs the roof, or is lifting walls.
Should I water it?
Established elms need little extra water. Extra water mostly means more seed and more suckers.
Replace it
What should I plant instead of a Siberian elm?
Good Las Cruces replacements are desert willow, chitalpa, thornless honey mesquite and Desert Museum palo verde for low-water shade. NMSU also suggests lacebark elm if you want an elm. Plant in fall and water deeply at the drip line.
See planting timing in our fall planting guide.
