Dollar stores are the perfect choice for good prices, after all, everything is a dollar. This year, I planted eight dollar store oil drip pans, (large, shallow plastic pans) with plants suitable for pressed flower harvesting.
I expected the plants in these pots to be spent and dried out by the end of June. What an unexpected surprise to find that these containers, planted with four plants each, have thrived and are still lushly growing. Careful watering is the key to success with shallow pans.
I might empty a few soon and try them out for an Autumn lettuce crop. Give the dollar store a try for unique containers that can be turned into inexpensive planters.
