Cheap gardening containers are easy to find with a few helpful tips, and they can be used for a variety of garden projects.
Stand Up and Garden (The Countryman Press, 2012) by Master Gardener Mary Moss-Sprague is a complete how-to guide for raised-bed gardening that allows anyone to grow robust fruits and vegetables in any climate. Change the way you garden with this excerpt from Chapter 3, “Containers – Your Chance to Get Creative on the Cheap!” and learn how to repurpose tubs and troughs of all shapes and sizes for use as cheap gardening containers.
Should you be brand new to the gardening scene, be assured that there is no one shape of container that’s more “correct” for garden use than another. Long, short, wide, square, round—all are perfectly good. This also applies to materials from which the containers are made. Wood, ceramic, pottery, fiberglass, plastic/resin/polyethylene—it’s wide open to personal choice and economical considerations. If you already have a container collection, make certain that it is suited to the plants you want to grow before you charge gung-ho into planting. Reading the rest of this chapter will help you decide if you need anything different. Remember one very important thing: Your containers must all have drainage holes or be able to withstand having holes drilled in them without breaking apart. Without proper drainage, your plants are doomed to fail.
Certainly, there are many very attractive (and expensive) pots and planters available in stores. The more utilitarian choices usually cost far less. Containers can often be found at yard sales, thrift stores, and other secondhand vendors, and I encourage you to go scouting for what you need before buying anything. Five-gallon food-grade service buckets can often be had for free at supermarkets or restaurants. Whiskey barrels cut in half work well; even large old truck tires will serve, when placed flat on the ground and the hollow filled with soil, although they’re not very aesthetically pleasing. Plant nurseries and garden centers sometimes sell off unneeded inventory, too, and you may be able to find some great containers at these places.
This is especially true if you’re in the market for larger, molded plastic tubs, also known as grower’s pots. If you don’t find these big fellas locally, the Internet is a great place to buy them at inexpensive prices. Just set your search engine for something like “plastic grower’s pots,” and you should find plenty of vendors who will be happy to ship to you. Three-, 4-, and 5-gallon pots can cost as little as a dollar apiece, maybe even less. The only catch is that there is usually a minimum order of 50 or 100. But that shouldn’t be a problem if you have friends or relatives who also want these containers. Simply share the cost of a shipment, and you’re in business!
Here’s an innovative idea: One of the thriftiest choices I’ve found are thick, black, rectangular polyethylene dishpans sold in dollar stores for—yes!—just one dollar. Thin, brittle plastic pans won’t work, though; the material must be a bit resilient and flexible. Polyethylene is the same material used for making livestock watering tubs, so it’s safe for this application.
See what some of the choices are and decide what you want. Then start looking. While the shape of containers and the material they’re made of aren’t important, we do need containers of different sizes. But why? It’s necessary because it’s not a one-size-fits-all world. A thriving Roma or beefsteak tomato plant bearing heavy fruit must reside in a container that can withstand the plant’s weight and bulk, such as a 5-gallon grower’s pot or food-grade bucket. This container must also be large and deep enough for heavy wire or wooden support stakes that will be added as the plant grows. All plants requiring soil 6 or more inches deep belong in the largest grower’s pots.

I disagree with the need for drainage holes in containers. Why not create sub-irrigated or self-watering pots instead? This is esp. crucial now in areas experiencing multi-year drought such as California or in seasonal dry areas such as AZ, NM, and TX. There are lots of plans & instructions online as well as ready to go systems for purchase at nurseries and gardening centers.
I grow mostly herbs and lettuces. The large Maxwell House and Folgers plastic coffee containers are great and they have handles!
I always grow cellery in containers to help me keep their roots wet enough. Containers are a great way to grow cut-and-come again crops, too.
My front porch is full of plants in containers - it looks very cottage-like!
One of my favorite recycleable containers is the waxed boxes that bananas come in from the grocery store. I simply need some old newspapers to line the sides, so the dirt won't fall out. I can get several seasons from a single box, and when it finally does start to break down; voila! extra compost! I have also used unwaxed boxes, but they generally only make it one season. To convert an unwaxed box to a waxed one, do the following: melt some paraffin wax, grab an old paintbrush and have at it. I woudn't recommend this activity for small children unless they are wearing work gloves; there is a potential for burned skin.
I make use of containers from our local Recycling center. They have lots of plastic containers, from 5 gal. ice cream containers to old bathtubs. I once saw an old porcelain toilet used, both the tank and the potty part (with the lid removed). I encourage everyone to make use of your local recycling plant and/or landfill and help save our planet. I agree that yard sales are a good source too (that's sort of recycling too or what people like to call Re-purposing.
This time of year I watch or ice cream freezers put out to go to the land fill.I drill a drain hole in the bottom and put a cork in the drain on the side. I use the plastic covers from meat, cheese, and veggie trays as containers to start seeds. I attempt to keep as much out of the land fill as possible.
I have grown summer squash in containers as small as 10 gallons. Are you sure squash and pumpkins are suitable plants for a container as small as plastic dishpans?
