How much do you water a mimosa silk tree??

Question

its like.. 20 years old

its like 30-40 feet high

Answer 1

You don't really have to water it unless your area is suffering a drought.

Mimosa is O.K. with dryer soil, poor city conditions.

Now if you are ,in drought conditions then this is what you do.

Use a cat food can or something of similar size.

Place it on the ground over the root system and set up a sprinkler.

When the sprinkler has filled that can then you are fine for that week.

Baring of course severe heat or wind.

Now I live in the Northern part of the United States on the New Hampshire Massachusetts Border.

I need to baby that tree with water in the early spring and summer, and heavy mulch in the winter.

I am NOT worried about it being an invasive species, but if you live in warmer climate then please give some thought to what the other gentleman said in his answer!

I have seen what Bittersweet, and Mile a minute weed can do to landscapes so be ware!

Answer 2

Here's some info on your tree.  Mimosa is an exotic invasive plant.  It's yours to do with as you wish, but here's an informative link.
