Utility fog that is used in place of, or in combination with, your garden soil, and is able to be "dialed in" to match the optimal soil composition requirements for each and every plant you have. It will change according to each plant's needs for water, nutrients, and soil density. It will also form shade when and where needed, automatically, or upon request. Further, it will keep out moles and gophers by forming instant temporary barriers; store sunlight via solar cells, for use on overcast days; detect and drive off harmful insects, perhaps via insect-specific pheromones; retain water and minimize evaporation (sophisticated networks of Garden Paste could include an irrigation system), and even identify and remove plants started via airborne propagation [sometimes referred to as "weeds"].
