The previous owner that we bought our house from had a slew of trees, bushes, shrubs, and other plants growing in the yard. Someone mentioned that we have a Russian Olive tree. Then, I was told that they were illegal now. I think that they are illegal to sell and buy, but what if it is fully grown in the backyard and we never planted it there in the first place?
I did see that it is not legal to sell or purchase in Colorado.
It is considered hight invasive so it is not a good plant.
You would not be responsible for an existing mature tree. These laws apply to the sale of seedlings.

By this time of year, I usually have given my trees a good pruning. Given that we are still having early fall temperatures in November, will it hurt my trees to prune them now? Thanks
Pruning now would be fine. Here is an article with more information on the care of the tree: https://www.gardeningknowhow.com/ornamental/shrubs/elaeagnus/russian-olive-information.htm
We recently planted a russian olive tree in our front yard in southern alberta. It has been in for about 2 weeks and is now developing several yellow leaves. The soil is heavy/dense around it with clay at the bottom. What would be the cause? Thank you..
It does sound like transplant shock from heavy, wet soil. Olives prefer dry soils, and will benefit from a looser texture to prevent water related issues.
Providing the correct care for the tree will be key to its survival and recovery.

e writing about how best to grow it? We in New England are grappling with this invasive. From your website: Russian olive is a Chinese native that is considered a non-native invasive species in all but the southeastern corner of the U.S. In the southeast, it struggles in the summer heat and humidity and often succumbs to verticillium wilt. Contact your cooperative extension agent for information about the invasive potential and advisability of planting Russian olive in your area.
In order to be fair to gardeners, everywhere, we must include information for all plants.
It would be very unfair for us to exclude information for some gardeners because the plant is invasive to others. Instead, it is the responsibility of every gardener to research and ensure that any plant that is planted is not blacklisted or invasive. Otherwise, we wouldn't be able to house much information on the site, as all plants have the capacity to become invasive to some degree, if given the correct environment.
Are Russian Olives a form of narcotics?
Not necessarily. The chemicals that it contains is more like aspirin or other mild pain relievers. I would recommend talking to your doctor, as I am not certified to give medical advice.
