Why would anyone NOT do such a thing unless there was information that it was harmful? We purposely and knowingly planted two she-oaks in our yard, understanding that they were native to Australia. Where did we go wrong?

Sissoos turned out to be a bad idea, but their country of origin was not the reason.

inchingwest, there's a huge list of many non-native trees and plants that grow well in our low desert climate/soil. For example, many plants/trees from Australia grow very well here as certain parts of Australia have similiar weather/rainfall as our desert. Surprisingly, many sub tropical/tropical plants do very well in our heat. Lantana, bougainvillea, citrus, pygmy palms, etc thrive/do very well here. And many of the non-native plants/trees are very low water users.

Because finding something that thrives and grows big in the desert southwest is a goal for many people and not very easy?

The issues weren't known until it was too late. Just because something isn't native, doesn't mean it can't be used and adapted for low desert use. Many plants found here are just that and do well.

If we stuck with that way of thinking we wouldn't have many of the fruits/vegetable/grains/flowers/plants that we grow and enjoy today. Most things we grow are native to somewhere else.

I removed the only sissoo we had in our backyard during the first week of September due to the mess it made and the hours spent cleaning up the pool after monsoons. Tree was 7 years old. I cut the stump as low to the ground as I could and then drilled about 20 holes in it. Over the course of the next 3 days immediately following its removal, I filled those holes with roundup twice a day. It is now December and the only shoots I had come up was 1tiny one about 15 feet from the tree. I'll keep updated in how it goes when spring rolls around.

I doubt you used the concentrate RoundUp which is 41% active ingredient.
Get some and use it, it will kill anything fast.

My Sissoo "volunteers" have slacked off considerably since the 3 stumps were ground down and I kept pulling out the babies for months. But there are still a few coming back, even though I have poured Round up, WD40, vinegar, and oil on them. You would think they would find another yard to come up in.

Wait until summer. Those new shoots love the heat!

Any time I find a shoot, I dig down and find the root. I poor straight stump killer on it. It seemed to have lessen how many appeared this fall. Hopefully by this time next year, I am rarely doing this. Just keep being very diligent I have heard. Don't go weeks without pulling the shoots.

Good luck!

Roundup does you no good on dead stumps, it's only active on green vegetation. It's absorbed throught the green leaves and stems then transported to the roots. With Soosoo's you need to spray the new vegetation as it appears.
