Planting in 10 gallon container and then in ground?
I am still trying to grow a zone six garden in zone 10.
I have had good results with tomatoes using Tom's 'container in a container" method. I am contemplating permanently planting mophead hydrangeas which I am importing into 10 gallon containers and then submerging them in my planter which I had built to line my patio surrounded with topsoil then mulched.The planter backs up to a wall of boulders which supports the driveway and is poured concrete sixty feet by 30 inches in my entrance garden. It gets about 4 hours of sun a day.I am just not giving up hydrangeas. I have had enough encouragement from my potted hydrangeas to try this I put 7 gallon pots in large containers and then I can control color and moisture. Any advice or thoughts from hydrangea gardeners would be very appreciated.
