I am on Team Alone also. DH is there for the hole digging and helping with the heavy lifting which has been a big help. He lugs home lots of large bags of potting soil for me as well. He loves to see the yard looking nice but would never actually buy and plant something.
Learning the names of the various plants is not working too well.
Once in a while he surprises me and gets it right !
The hour of hand watering every day would not be entertaining enough for him.
I agree Mary, when DH is finished helping with something in the yard, he is finished!
