Doomed weeds, now that sounds promising! The one I have labeled “doomed’ is one that just got a spring glyphosate (RoundUp or equivalent) dose. I do a “surgical” strike on my beds before all the plants grow out for the season. Luckily, grass and weeds often emerge and begin active growth early, before the garden plants. Since glyphosate is only active when absorbed through the foliage not the roots, I can spray into tight areas if I get there before the other plants emerge from dormancy. I have to watch carefully and keep it off the desirable plants, but it is much easier in early spring.
You can also work a bit harder and manage weeds with organic methods. I admire gardeners who do so, such as the one pictured below busy in her beds. In a small residential space, gardeners like her prove that it works.
The best control of weeds is by frequent weeding, getting them before they go to seed. A tool like the winged weeder shown here is a great back saver and you’ll cover ground about 5x faster than without it. Every gardener needs one or a similar product. Add to that a hori hori, the Japanese digging, dividing and weeding tool and you’re ready to make sure that you, too have “doomed weeds”. We carry the hori hori, and hardware stores all have long handled weeding tools like the Winged Weeder.
