Container gardening is the last of the 3 gardening methods, and it occupies less space than raised gardens and traditional gardens.
The growing media is entirely different from that of raised gardens and traditional gardens in that the growing media has a minimum content of mineral soil. The growing media consists of milled pine bark, peat moss, sand, osmocote slow release and micro element fertilizers. This is referred to as a soil less mix. I do not try to re-invent the wheel, I buy industry formulated brands such as Miracle-Gro Potting Mix with micro element fertilizer included. Sta-Green Potting Mix is another product, but does not contain micro elements, however the milled pine bark in the mix may contain enough micro elements necessary for healthy plant growth. For those gardeners of the “organic” persuasion, Sta-Green sells a potting mix just for you. If I were growing vegetables on a large volume, I would mix my own. The internet is full of potting mix formulations for organic growers and non-organic growers.
Containers come in various sizes, shapes and colors. However, all containers have 3 things in common. They all must have a container side wall, a container bottom and bottom drainage holes. The size is determined by the width and depth of the container. I have noticed that potting soil deeper than 10 inches is a waste. Vegetable roots rarely grow deeper than this level except root vegetables such as carrots, potatoes etc.
Container sizes vary from a 5 gallon bucket to a kiddie wading pool with holes drilled in the bottom. The smaller containers with tender plants are easier to move indoors during frosty nights, and move to areas of full sunlight during the day time.
The following table is based on my observations and beliefs.
This article concludes the 3 gardening methods, however, make sure to read next month’s article, March issue, for a new and improved container growing method. It is called “Variable Level Container Growing” Happy gardening to all. Pro. Ron
