Hi Joe,

One thought that comes to mind is recycling nursery pots. Here in Maryland we used to have a nursery that had an area where you could bring used nursery pots and anyone could take what they needed. I can't stand putting them in a landfill. I have gone to plant swaps where I offer free pots to others.

Using greywater from houses and catching roof-runoff in barrels.

I don't have any NEW ideas, but here are tons of old ones:

composting
integrated pest management
organic fertilizers and pesticides
capturing rain water for watering (rain barrels, cisterns)
planting native plants (that need less water and fertilizer)
choosing other ground covers beside turf grass to eliminate mowing.

Using "waste materials" in place of purchased materials for seedling pots.
I use milk cartons with the top cut off and bottom corners cut out for drainage. I also use yogurt cups with holes poked in the bottoms. These are good for larger plants like pumpkins. I just plant the milk carton in the ground and the roots will grow right through the holes. At the end of the season there is a little bit left of the carton to pull up and throw away.
My favorites are the fiber egg cartons since they are already formed and can be cut apart and planted right in the ground like the peat pots.
You can also cut paper towel/toilet paper tubes to the right length, fill em with seed starting mix and plant in them. Just be careful when lifting them to plant so the dirt and seedling don't fall out the bottom.
I also use old phone book pages formed into cups (works with newspaper too) for plantable seed pots. You don't need any special tools to form them. Any cup, vitamin bottle, or whatever is the right shape you want can be used to wrap them around and fold up the bottom.

On another topic, stop flushing. It's bad for our water supplies and robs our gardens of nutrients.

This is a totally recycled garden. The brick is actually cement from our old inground swimming pool (that we removed). We simply flipped the cement upside and stacked it up. I bought the trellis in the picture for $1 and just had to find place for it so I framed it with recycled wood. I used recycled paint from our local recycling center to stain it. Even the birdhouse is recycled. I traded a friend some plants for the birdbath and my dad made the base for me by welding an old wagon wheel onto a steel shaft. The birds love it and so do I. I'm proud to be a recycler. I know that I'm doing something good for the environment.

Use shredded paper in your compost. Great worm bedding! Shredded paper has fibers that are too short for paper recyclers, and they will reject whole loads of otherwise recycleable paper (to the dump) if there is too much shredded paper. But it makes great compost, and sequesters plenty of carbon. Be sure to layer it, and to use a nitrogen source to help the soil beasties digest it.

Everyone has something that works in their area. We are in NE Iowa. We keep 4 gardens in long narrow strips separated by lawn. We rotate them yearly so the same type plant is not in the same area but every 4 years. No nightshade plants follow each other. We use organic cow manure. Rather than mulch we hoe. We plant things close together to form a canopy, which helps keep moisture in and weeds out. We use Ivory Liquid for pest control. Earthworms are plentiful. This works for us and keeps us in organic foods for our table and freezer.
