@Irishmike, you had such a good Idea I've done the same with mine. Going to see how they do over the compost (Its pretty hot with nutrient) You've got some nice sized planters. They honestly look really good in there shame we can't grow them in the flowerbed for the neighborhood like we do roses. cheers.
@WatercanWampa,
Yes and no lol, I'm working on building wooden planters 2 feet x 2 feet X 18 inches tall, filled with a potting mix. I will till the dirt under them and hope they root deeper.
