Do ornamental willow trees have the same problem growing to a water source as regular willows?

Question

i'm interested in getting a curly willow or a similar ornamental willow for my back yard. i've learned that regular willow trees will grow and their roots will seek out a water source. i don't want it to interfere with the water pipes that are underground.

Answer 1

A Willow is a Willow is a Willow. All willows have invasive roots.
The Corkscrew Willow ( Salix "Tortuosa") will grow to 30 feet with a 20 foot spread. Typically tree roots grow at least to the drip line of the tree so you will be looking at - at the very least - a 20 foot spread of roots.
I might suggest you grow it in a giant, really giant, tub and keep it pruned ( sort of Bonsai it ) They really are a beautiful tree. Especially in the winter and silhouetted.

Answer 2

I don't know.

Willow tress do usually grow near water sources though so I assume they need lots of water. Most pipes are tight enough that the roots won't grow into them. If they do, you dig down to the pipe 4 to 8 feet maybe, then just put some metal around the pipe at the junction.

Answer 3

The roots do tend to grow towards a water source. The real problem is having roots grow towards your foundation. Do not plant on the side of the house that has the air conditioner drain. Their roots are shallow. Cut any that you see growing towards the house.

Answer 4

All willows suck up water big time and roots can grow as much as 60 feet in search of it. Beware!
