What's in your garden?

[Juniper]

I don't think plants that spread do so where I live. The trumpet vines were on the fence and didn't spread anywhere for 20 years or so.
I think where I live, on the Agate desert nothing spreads because unless I water the ground is bone dry.

There's definitely places plants prefer. I have a philosophy that if I find a place where the plant is happy, that's where it stays.

I think most of the valley has the black sticky soil that never dries out, IMO that's when Bamboo and other plants just keep spreading.

My giant Bamboo has a lot of new canes this year. This makes me happy

Why don't you just plant Ailanthus trees while you are at it?

What does that have to do with Bamboo?

Obnoxious, aggressive growing things.
