Every summer for the past few years, I’ve noticed the same thing on neighborhood walks — one or two backyards that used to be totally forgettable suddenly stop me mid-stride. I think not because someone hired an expensive landscaper, but because a handful of ideas keep spreading yard to yard the way trends actually spread: someone tries it, a neighbor leans over the fence to ask about it, and within a month it’s everywhere on the block. This summer’s crop of garden trends is exactly that kind of contagious. Here’s what’s actually taking over backyards, patios, and front yards right now.
