Today’s we’ll talk about composting — right in the middle of your garden! But first, what do we mean by a “smart garden” idea? Many people think that here at SPI we do a lot of teaching of how to grow vegetables. The truth is actually the opposite: we do a lot of learning. Our program philosophy is to engage local leaders to share gardening skills and ideas with seed recipients. Their skills and ideas are truly smart gardening: these techniques use every available resource already on-site to minimize waste and cost. Water is considered a precious, finite resource -- a worldwide truth that is too easy to ignore when we have an apparently infinite supply coming out of our hose. Gardening can feel easy where amazon.com, Wal-Mart, or our local store sell every type of soil amendment or tool we might need. But this type of gardening uses a lot of resources and can be expensive for the gardener. By learning from regions like East Africa and Central America, we can save money, reduce household waste, and maybe even grow better vegetables and flowers.

Today’s idea is the compost basket. “Basket” is not a literal term, but instead refers to any structure you might build in the middle of your garden to hold compost. U.S. gardeners are fond of composting in a special pile or bin and then carrying the finished material to the garden. But this work is unnecessary, and the missed opportunity comes when rain falls on the pile or moisture seeps from a covered compost bin: much of the wonderful soil-enhancing nutrient potential is lost into the dirt nowhere near your garden.

Instead, steal this idea practiced all over the world, coming to us most recently from our collaborator Sostine Mukhebi at the Kenya Department of Agriculture: compost right in the middle of your garden, and then water your garden through the compost pile. Here’s how:

  1. Make a tube or bin-like structure out of material of your choice. It can be about 2 feet wide and 4-5 feet tall; a section of wire fencing rolled into a cylinder works well. If you’re more of an artisan you can form a truly basket-like structure from woven sticks or vines. Place it in the middle of your garden bed and mark its footprint. Remove it.
  2. Dig out this area below ground level. Sostine recommends 60 cm (about two feet) but your soil might make that difficult; do what you can. The width of the hole should be about the same. Put your bin structure in the hole and fill up to soil level with a mix of rocks and organic material. This initial effort to ensure below-ground drainage will help the good stuff from your compost pile reach your vegetable plants’ roots.
  3. Prepare your garden bed around the compost basket just like you usually would. Allow 6 inches from the basket to where your first plants grow, just in case the level of nutrient flow from your compost is very strong.

Now that your compost basket is proudly centering your garden bed, just add any compostable material: kitchen scraps, coffee grounds, old oak leaves, lawn clippings, and aged manure from livestock or poultry. Periodically layer in sticks to keep air flowing through the pile, as it’s hard to turn the compost. If your neighborhood sports wild critters like raccoons, rats, or bears, avoid any prepared foods more fragrant than vegetable peelings, or build the bin from a sturdy narrow gauge type of fencing and keep it covered.

Water your plants as normal when they are very small, but as they grow, or in addition, water the garden bed via the compost basket in the middle. This is an especially good use of “greywater” such as rainfall captured from your roof, or water leftover from the kids’ play pool on a hot day.
