The container gardener is limited only by his imagination. Consider the following guidelines when choosing your container. Avoid containers with narrow openings. Cheap plastic pots may deteriorate in UV sunlight and terracotta pots dry out rapidly. Glazed ceramic pots are excellent choices but require several drainage holes.
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.
