what will happen if i put some garden soil from downstairs ontop of it some of my homemade compost and on the top bought planting soil?
for example plant sunflowers or sweet corn.
why?
to save money1.
to avoid evaporation since the planting soil has a bigger capacity of holding the water 2.
from the point of view of the plant i know it will meet another type of soil on its way down.....
how critical is it?
