Q.What Is The Best Organic Soil Mixture For NYC Urban VERTICAL GARDENS? For Herbs And Leafy Greens?
I am a complete beginner gardener in NYC. I haven’t even started my garden but wanted some expert advice and how to pick the perfect soil + compost + fertilizer mixture for an organic vertical garden and for raised garden beds. I understand it is not recommended to use the same soil for both projects. This is why I am here.
