Mike........I enjoy growing Lillies both in tubs and in the ground.
I was interested in your mention of drilling holes in the sides of pots ( as well as the obvious bottom drain holes ) and then sinking into the ground. It makes a lot of sense but you don't say whether you would use clay or plastic pots for preference.
I'm guessing clay but ? I wonder if you could clarify this point ?
Thanks for such an informative post..........sounds like I'm doing everything as per your recommendations but nice to have it confirmed
