Recycling Other Cardboard Rolls
An alternative to toilet paper rolls is recycling cardboard rolls left over from wrapping paper, aluminum foil, and plastic wraps. These sturdier cardboard rolls can be cut to any size you need. The taller homemade peat pots are actually better for rooting woody cuttings for your garden, because they don't break down as quickly.
Once your seedlings or cuttings are ready to transplant, you simply place your homemade peat pots into your garden soil or container, and they will break down just like real peat pots, becoming part of the soil.
Another way of recycling cardboard rolls for your garden is to flatten them and cut small pieces to cover holes in the bottom of pots. The water will get through, but the soil will not.
To keep weeds out of your pots, try recycling cardboard rolls by unrolling them and placing them on top of the soil, under a layer of mulch or rocks, much as you would use cardboard boxes in your garden.
If none of these tips for recycling cardboard rolls in your garden interests you, simply cut them up and put them into your compost pile. Whatever you do with them, don't just toss them out!
I'm sure that you can find a myriad of other ways of recycling toilet paper and other cardboard rolls. Using your imagination for recycling common everyday items that were once thrown away can go a long way toward saving our planet.
