TL;DR
Gardening Know How has published a guide to eight ways gardeners can repurpose household cans, including seed pots, cutworm collars, tool organizers and lanterns. The ideas are low-cost, but cans need cleaning, safe edge handling and drainage where they will hold plants or water; the guide also warns that metal eventually rusts.
Gardening Know How has published eight suggestions for turning clean, empty food cans into garden supplies, including seed-starting pots, cutworm collars, storage containers and lanterns. The guide presents the projects as inexpensive reuse ideas, while warning that sharp edges, drainage and eventual rust need attention.

The article says cans can be repurposed because they are rigid and can hold soil or water for some garden tasks. Its seed-starting suggestion is to punch several holes in the bottom with a nail and hammer, then fill the can with a light, sterile seed-starting mix rather than garden soil. Since metal does not breathe like terracotta, the guide advises checking the mix before watering. To transplant, remove the bottom and push the root ball out.
For pest management, the guide recommends cutting both ends from a can and setting it around a seedling, with 1–2 inches (2.5–5 cm) below the soil and a few inches above it. It says this can help guard against cutworms, but cautions that cans are not a dependable barrier against slugs. Hanging cans may startle birds temporarily, though birds can become accustomed to them.
The remaining ideas include holding twine, labels and hand tools; scooping compost or granular fertilizer; growing compact herbs such as thyme, chives and oregano; and making punched-can lanterns, much like repurposing toilet paper rolls for garden projects. The source also suggests keeping clean cans for seasonal uses, including a winter shelter for hollow stems. Its headline promises eight ideas, but the supplied source excerpt ends partway through the lantern instructions, so the full list is not available here.
Low-Cost Uses for Garden Cans
Reusing a can may spare a gardener the cost of a small pot or storage container and give packaging another use before recycling. The practical value depends on the task: cans can organize a potting bench or serve as short-term seed pots, but they are not a substitute for reliable pest controls where damage is a concern.
The safety and care details affect whether the projects work. Drainage holes help prevent water from pooling around plant roots, while gloves and pliers or a file can reduce the chance of cuts from sharp rims. Rust may develop as coatings wear, particularly where cans remain wet; the article says a can with some rust may still suit seasonal jobs, but cans too deteriorated for reuse can go into metal recycling.

Preparing Cans for Garden Use
The source frames can reuse as a household recycling project: rinse and clean cans after use, remove labels and glue, then store them until gardening tasks arise. It suggests building a supply during fall and using some for seed starting in late winter. These are recommendations in the Gardening Know How article, not reported results from a test or formal study.
Before using a can outdoors, the guide advises washing it with hot, soapy water and checking the edges. A smooth-edge opener may leave a less sharp lip; otherwise, jagged areas can be flattened with pliers or filed. The article recommends wearing gloves while handling edges, punching drainage holes in planters, and painting the outside of cans intended to stay outdoors for an extended period. It says paint should be allowed to cure before planting and that dark cans can heat up quickly in full sun.
““They’re stiff, hold soil and water without leaking, and cost nothing after being discarded.””

Limits of the Can Projects
The provided source material contains only the beginning of the lantern instructions and does not include the eighth idea or the complete article. The headline says there are eight uses, but the available text supports only the uses described above; the missing suggestions cannot be confirmed from this excerpt.
The source does not provide comparative tests, costs, or evidence measuring how well the ideas work. It describes cutworm collars as useful, but says slug protection is unreliable and hanging cans may lose their effect as birds get used to them. How long a can lasts will also vary with its coating, exposure to moisture and intended use.
Using and Recycling Cans
For gardeners trying the projects, the source’s practical sequence is to clean cans, check and blunt hazardous edges, and add drainage where plants will grow. Seed-starting cans should be monitored for moisture because metal does not breathe like terracotta. Cans used for fertilizer or compost should be cleaned and stored dry, and should not be returned to food use.
Gardeners can keep using a can while it remains sound for its task, then recycle it through an appropriate metal-recycling service when it is too worn. The supplied material does not state whether Gardening Know How plans a follow-up or provide a publication date for the article.
Key Questions
Can tin cans be used to start seeds?
Gardening Know How says they can, provided you punch drainage holes in the bottom and use a light, sterile seed-starting mix. Check moisture before watering because metal does not breathe like terracotta.
Do can collars stop garden pests?
The guide says a collar placed around a seedling may help protect it from cutworms. It warns that slugs may climb over a can, so it should not be treated as a dependable slug barrier.
How should I make a can safe to handle?
Clean the can, inspect its rim and flatten or file jagged edges. The source recommends wearing gloves while working with sharp edges; a smooth-edge opener may leave a duller lip.
Will a can rust outdoors?
Yes. The article says the tin is generally a thin coating over steel, which can rust as rain and wet soil wear it down. It suggests painting the outside of cans left outdoors for longer periods and recycling cans that become too worn.
