Native perennials, including black-eyed susans, enchinacea, and joe pye weed sit halfway through the garden, which lines our east fence. It’s an average size yard for a single family (not a rowhouse) in Baltimore.
Finally, we compost. Everything. Weeds, food scraps, old plants, coffee grounds- you name it. I keep the compost super hot all summer to keep the rats out, then I’ll sift some almost-there compost and feed it to a 5 gallon bucket of worms. Whenever the buckets fills up, I drop handfuls of worms in each of the garden beds.
