It turns out a garden two feet deep and 6 feet in diameter takes more material than you’d think (yes, the math is easy, but so is convincing yourself that you have plenty of materials on hand that fill the required volume). For the brown layer, I used quite a few very large cardboard boxes (saved and snagged from local retailers), a few 2013 phone books, and all the paper-based recycling we could scrounge. For the green, clippings from the first mowing, and bark and sticks from the tree I felled last year (from the pile waiting for the chipper), then random dead cuttings from the herbs and flowers. Normally our lawn produces a recycle bin of cut grass–this year, I raised the mower deck to its tippy toes to accommodate the wet lawn and encourage even growth. The result: a relative tablespoon of cuttings. Maybe there’ll be more for the next bed.
The results, before adding dirt:
Note: the funnel cake-shaped roll of paper in the compost cage was added to retain the contents initially, just in case the grid was too large. It rained the next day, crumpling the paper. I dumped compost on top–the cage held it just fine.
Day before yesterday, I started liberating the nice black dirt from our big raised bed next to the fence (and associated tree roots). Plenty of dirt to top off the keyhole bed, my optimistic lobe said. Not quite. 3/4 of it moved and still a good ten inches (x 6 feet) to go. I’ll scrounge dirt from other sources around the yard, then see what it costs to buy a trailer load from our local landscaping supply yard. I’ll probably pay their suburb-jacked prices to go easy on our minivan versus driving significantly further out. (We need the van–a 2005 Caravan with 130k–to last a few more years. It shows my age to think that anything made after the magical year 2000 AD–like my daughter–still sounds new.)
So bed #1 has become our learning (or teaching) garden, providing a realistic estimate of work and materials needed to build a keyhole bed: a template that we can plug into our garden budget and calendar. Having that info on hand has freed us to think about other garden-related dependencies to address before or while the second bed goes up.
And when it’s all done, then we shall bask in the admiration of our neighbors…
Or, more likely…
