I Cut Up My Greenhouse!

Polyvinyl is a great material for greenhouse covers, but it has a limited lifespan due to normal wear and tear, and more importantly, UV exposure. Over time, the material weakens and becomes less effective at providing the right conditions for plant growth. Instead of discarding my old polyvinyl, I decided to repurpose it in a creative and functional way—by making seed snails!

What is a Seed Snail?

A seed snail is a method of planting where seeds are arranged in a spiral pattern to maximize space efficiency. The concept mimics the natural spiral formations seen in nature, such as snail shells or sunflower heads, which optimize the use of available space. By rolling a planting medium into a spiral, you can create a compact, organized system for starting seeds, making it easier to manage and transport them.

Making "Seed Sushi"

As I started filling and rolling my plastic strips with soil and seeds, I found myself calling this method "seed sushi." Much like rolling sushi, I carefully packed the strips with a balanced mixture of growing medium and seeds, ensuring they would have the best chance at germination. This technique allowed me to create flower and vegetable rolls in February, giving my plants an early start while saving valuable space in my greenhouse.

A Sustainable Solution

Repurposing old greenhouse plastic for seed starting has given it a second life, reducing waste while serving a practical purpose. Traditional seed trays often have a short shelf life, and rather than continually buying new ones, this method provides an eco-friendly alternative. But no one has to cut up their greenhouse to do this—you can get creative with other materials like old chicken feed bags or anything else you have lying around!

By thinking outside the box, we can turn old materials into useful gardening tools, promoting sustainability and efficiency in our growing practices. So next time you’re about to throw something away, ask yourself—can this be used to start seeds?
