Last year I applied Lesco's pre-emgerent Dimension and it worked great! Weeds/crabgrass almost entirely eliminated. Therein lies the problem. I'm left with a bunch of bare spots that wouldn't allow new grass seed to germinate. So this year I am confused about what to do...I need to re-seed a large portion of the lawn because of the bare spots, but I want to fertilize what little grass I have left. Which fertilizer should I use before I re-seed or should I re-seed the bare spots first and then fertilize? And in any case, I don't want to use pre-emergent weed preventer since I will be left with the same problem. Any help is greatly appreciated! Thanks.
