Okay, well since no one seems to know, I'll report on my little experiment when I get some results. I have a live oak that suckers like crazy. I decided to try to dig some up. However, I was only able to get to the roots on 3 of them. The rest I cut off at the ground. Decided to try to treat the ones cut off at the ground as cuttings. Seems like a sucker is very young and vigorous and could yield some results. Of the three that had some roots or at least what looked like a rhizome attached, I potted out the best of the bunch as is. I decided to experiment with the other two since one only had about 2 root hairs and the other had rhizome material but no roots at all. I cut each of these two into separate stem and root cuttings. I'll let you know if any of these survive.

Interesting. Yes, let us know.

So far the one that was a complete sucker is looking great. It's in a bigger pot, so keeping the soil moist but not wet is a little easier.

One of the stem cuttings appears to have died. It is in a tiny, I think 2 inch, terracotta pot that dries out very quickly. Skipped one day of watering as the soil still looked damp. Next day I went to water it and the top of the soil was dry with the plant wilted. Hasn't recovered. All other cuttings still looking good. 2 root cuttings haven't pushed up shoots. Obviously given the time of year, they won't send up shoots until spring if they ever do.

Here in Central Texas we are still getting 75/50 temperatures, so hopefully everything roots before we get real winter weather and then they make it through to spring. I am not inclined to bring them in the house.

Full sucker still looks great (not much surprise there). I think about half of the stem cuttings are not looking good. Wilting leaves. The two root cuttings haven't done anything.

This is all being done outside with no misting. Just regular watering. So the failures of the stem cuttings aren't much of a surprise. I'm more interested to see what happens with the root cuttings. Seems to me that any plant that sends up suckers should be able to be grown from root cuttings. But that doesn't mean my care and techniques have been correct enough to make it happen.

Unfortunately, most things seem to have died, including the sucker. I think there are 2 stem cuttings that still have green leaves. The rest had their leaves turn brown and wilt. I'm still hoping maybe they're still alive and will grow in the spring, but I doubt it. The root cuttings haven't done anything, but I wasn't really expecting them to do anything above the ground until spring.
