Container - I start with a gardening container that is food-safe. Glass, ceramic, stone, untreated wood, and food-safe plastics are all things I have used in my garden before. If you are concerned about the container's composition, be sure to research before you buy and select the qualities you prefer. Last season I used Crescent Garden Planters and really liked them. They are lightweight, are stylish, have a good drainage hole, and on the bottom, there is a special hole in the containers that allow you to weigh them with sand if needed. I loved that the large Delano container in "Old Bronze" also came with a plug so that you could plug the container, fill it with water, and convert it into a mini pond. Each container is food-safe.
Organic Soil - Last season I used Espoma Organic Potting Mix which has worm castings mixed in among other natural ingredients. Using this product alone is great, but should you require heavier soil, you can use the potting mix as a base and mix in rotted manure or compost.
Organic Fertilizer - Dependent upon the plantings you might select all types of various organic fertilizers to help feed your plants. I chose Espoma Rose-tone for the containers with flowering plants and Espoma Garden-tone for the foliage or vegetable plantings.
Plants - Every year I have a different theme for my container planting schemes and my goal with this season's style was green-on-green foliage. My experiment was to find out what would happen if I mixed various shades of green in the planters to contrast with the "Old Bronze" Crescent containers. I mixed Caladium 'White Queen'. Sweet Potato Vine 'Marguerite', and Asparagus Fern with several selections from Jung Seed - Begonia 'White Ballerina', Dusty Miller 'Silver Dust', and Vinca 'Ralph Shugart',
Watering - I use drinking water-safe garden hoses so that the water which is placed on the plants is without heavy chemicals which can be found in traditional garden hoses.
