They look great! Although I'd be too scared to not replace all the clay with good soil. I do know that the plants don't really need all of it to be changed and the area beneath the plant is enough but...kinda my habit I guess
My congratulations! A big step for a family man, you know as they say - plant a tree, build a house, rise a son. Family values is not something to ignore and that's a remarkable date! All the happiness to you and your kids!
