Good Idea or Bad Idea?
Newcomer here, and after years of fighting with bad soil in the flower bed in front of our house I've come up with and idea I'm not sure about. Every year we try to plant different flowers in the bed in front of our house only to end up with everything dead, except the weeds and the silver lace vines. We've had tremendous success with potted plants in the same areas of the garden so long as they're in potting soil. So the idea we've had is to dig up the entire bed, which is about 165 sq feet. I want to dig down about 5-6 inches, put about a 1" layer of sand and fill the rest up with gravel. Keeping the potted plants either above ground, or possibly concealed in the gravel to provide the illusion of plants in the ground.
So the questions are:
Is this a good idea or bad idea?
Is there any risks of removing 6 inches of dirt from against the house?
What's the best way to quickly excavate the area, I don't want this project to take up more than a day or two?
Are there any other suggestions in changing out a conventional flower bed for a rock garden flower bed?
