Hey Funkbomb. I went to Lowes and was gonna pick up a bag of sta green. The only one I saw that was a nursery mix was for trees and shrubs. Is that what you use? The other one they had was for bedding flowers and vegetables but didn't say nursery mix.Go to Lowes and get some Sta-Green Nursery Blend Planting Mix. Add some perlite and you're ready to go. At $7 for 2 cubic feet you will not find a cheaper yet effective soil.
