Miracle-Gro vegetable soil is an in-ground soil, meant to be added to the existing soil in a vegetable garden. This is a heavy, dense and compact soil that will dry out too quickly in the confined space of a container. In fact, Miracle-Gro representatives clearly state that this soil should not be used exclusively in pots or containers. Miracle-Gro vegetable soil can still be used for your container plantings as long as it is amended to create a lighter soil that drains well.
Combine equal parts of Miracle-Gro vegetable soil, vermiculite and peat moss.
Pour water over the mixture, gradually, while stirring. Continue to add water until the mixture is uniformly moist.
Scoop the mixture into the planting container, using your gardening trowel, and allow it to sit, draining, for one hour. The soil is now ready for planting.
