15 trees you should never grow in your yard
Siberian elm (Ulmus pumila) is a fast-growing, aggressive tree that tolerates all kinds of difficult growing conditions.
But it’s messy, seeds itself all over the place, and frankly isn’t the most attractive tree.
Siberian elm is also weak-wooded and prone to storm and ice damage.
It also needs a lot of pruning if you are to keep it under control.
