Container garden types include vegetables, herbs, annuals perennials, small shrubs or trees, or a combination of any of these. Themed vegetable and herb gardens include spaghetti gardens, pizza gardens and tea gardens, among others.
A spaghetti garden includes herbs that one uses to make sauce, while pizza gardens contain herbs for making pizza. Tea gardens contain different herbs with leaves that can be steeped.
It is important to match the size of the container to the type of plant that is selected. Containers must provide adequate room for root growth. This includes depth as well as width of the root ball. Multiple plants in a single container must be spaced according to their growing habits, so spacing considerations must be taken into account.
Clay pots, plastic pots and metal pots can all be used for container gardening. Nearly any container will do, as long as it has adequate drainage and the container is non-toxic. Wooden planters are suitable for container gardens as well, but longevity should be considered as wood eventually decays.
