One of the most widely used foods by wildlife are acorns. If it is acorns you desire, but don't have any Oak trees, you will be waiting at least 20 years after planting native Oaks before you see any substantial acorn production. Although I had many Oaks of several species growing on my property, they would sometimes go years between good mast production. I planted 25 Sawtooth Oak on a fence row which started producing acorns consistantly in 8 years. I also liked the fact that the trees retained their leaves well into the winter creating a wind break and a visibility screen. The tree is not a native but in the past 5 years of producing acorns, I found only 2 seedlings in the vicinity of my original planted stock. These two seedlings have not grown above 18" tall due to deer browsing. I wou... read more

The jury is still out on this tree imo. It does grow fast, for an oak, which is the primary reason why many people are planting it. However, as others have stated it is considered an invasive species in many areas of the country, if that sort of thing bothers you. The other thing to consider, and more importantly imho, is how resistant it is to diseases in the many climates of the U.S. It may grow fast, but that would be useless if it is discovered 20-30 years from now that it is vulnerable to some sort of vascular disease or fungus. For this reason alone, it may be wiser to plant a native oak tree that is proven to thrive for hundreds of years in your own climate.

Beautiful tree! It's only invasive in my yard but no problem to control.
I have been growing these trees in my yard for over 20 years, fruiting started over ten years ago but have only seen maybe two come up elsewhere on my 8 acre property. I have yet to see a single one in my area.

The sawtooth oak is a fast growing tree that produces mast in about half the time, seven years or so, of other oaks. It is a very pretty tree AND it is very beneficial to wildlife when planted after a clear-cut harvest.

This tree has been in Georgia for several years and has not proven to be invasive to this point. Possible reasons may be that wildlife consume the majority of the seed as opposed to certain other acorns that are bitter and less preferred.

I personally do not care about the value of any oak as a fuel source. I venture to guess that wood burning in the USA will be highly regulated in the not too distant future.

Decent, very fast growing shade tree. Deer love the seeds. Prolific but easily controlled with a lawn mower. Bad points: not as wind resistant and strongly rooted as our other oaks in 135 mph winds. Firewood not as good as live oak.

I am really disappointed that these trees are being sold everywhere I look. It's native to Asia, grows really fast, and puts out a zillion seeds. Have we not learned anything from the Chinese tallow tree? With the large variety of native oaks we have in America, I can't imagine why anybody would wan't the sawtooth.

It's also ugly, IMHO

Has been labled as invasive in some areas. Note, don't let the fact that it's an oak fool you, this is not native to North America.
