Warning: This is another one of those “can’t she just throw it away?” posts. And no, I can’t!
We have very sandy soil, which is great for growing asparagus, but the other plants I grow in my garden require more water and less drainage. There are companies that manufacture moisture control soil, but it is very expensive, so I decided to create my own. I mix dryer lint into the dirt along with compost.
We primarily wear cotton clothing and use cotton towels and sheets, so the dryer lint will easily break down in the soil. I would not do this with lint from synthetic fabrics. I tear the lint into small pieces and turn it under with a shovel. The lint retains water and keeps it near the plant’s roots.
