Wooden containers are susceptible to rot. Redwood and cedar are relatively rot resistant and can be used without staining or painting. Avoid wood treated with creosote, penta or other toxic compounds since the vapors can damage the plants. One advantage of wooden containers is that they can be built to sizes and shapes that suit the location. Use containers between 15 and 120 quarts capacity.
Small pots restrict the root area and dry out very quickly.
The size and number of plants to be grown will determine the size of the container used. Deep rooted vegetables require deep pots. Make sure your pot has adequate drainage. Line the base of the pot with newspaper to prevent soil loss. In hot climates use light-colored containers to lessen heat absorption and discourage uneven root growth.
