It is always wise to add a slow-release fertilizer for continued feeding of your plants. The varieties of containers one could use is almost endless. Color, size and texture are important, however, the most important consideration when choosing a container is whether it has adequate drainage holes. Container size is also important. Outdoor container plants, especially rapidly growing plants such as summer flowering annuals, need adequate space for root development.
Small pots restrict root growth, dry out too fast, and often result in limited growth and flowering.
Think in terms of containers holding several gallons of potting mixture. These will produce the most attractive and healthy plants. Performs best during cooler seasons.
