I promised on last week’s post that I’d mention some other low-input methods of keeping weeds out of the gaps between paving stones. Here are a few photos of my own yard, where we’ve been installing flagstone pathways and terraces. (Money-saving hint: check out craigslist and/or freecycle for free pavers and other types of stone. We got all of ours free – just had to pick them up.)
We bought flats of groundcovers, such as woolly thyme, Irish moss, and blue star creeper. In sunny areas, these plants thrive and spread quickly. But in shadier, moister areas they haven’t done so well. Instead, we’ve allowed nature to fill the gaps for us. Naturally occurring mosses, ferns, and other small plants keep out annoying weeds yet are small and attractive in their own right.
You can jumpstart the process by making a moss “milkshake” to spread between pavers. There are recipes on the web, so I won’t bother repeating them here. I prefer to let nature take its course (or maybe I’m just lazy).
