The ideal sizes of grow bags for a variety of common fruits, vegetables, and herbs are listed in the charts below.
Please note that the grow bag sizes listed below are measured in gallons which can make it difficult to determine how much soil it takes to fill it . I have also found that the actual height and diameter of grow bags can vary from manufacturer to manufacturer. Some are shorter and wider and some are taller and skinnier. You can also increase the size of a grow bag if you wish to have more growing room or for moisture management but it is not recommended to use smaller than the recommended sizes below.
