I dug up the base of that red oak and filled it in with Moisture Max soil, and planted something called Hidden Ginger Lilies, or Curcumas. I've never had them before. They are tropical, but supposed to be ok up to zone 8. But it seems to run cold here in my yard, so I don't know it they will over-winter or not. Still- they are very pretty! I brought over a drip sprinkler from the Terra Pen line, and another one out of a row of crape myrtles along the back of the house, which waters all the trees in the back, so they should have plenty of water! And I think I decided where to put the rescue tree. It's just too hot to dig a 30 gallon hole right now.
