my dorset horn is obesum hybrid, and the other one looks like one the first dorset horns,

That would make sense Thanks

I really like the DH, but I think my heavy watering would kill them!

If I ever have one, it will be from seed.

So many on the market today are grafted. I don't like those.

If your other tree's take the water why wouldn't the DH?

I just heard they were slow growers. I killed two small plants earlier this year before they weren't fully awake.

I'd need to separate them. Although I suppose I am going to be forced to now anyway. I have some types now that will go dormant according to the experts. Things will get interesting for me around late December..

Weather changes after Halloween. Mine will just have to go dormant if it stays cloudy. We have natural solar in the Great room for extra heat.

Or we can move to Hawaii JP's seem to grow pretty fast and he seems to get a good percentage of DH to curl.
