overseed or start over??
Problem: Rear yard (aprox 5000xq.ft) Full sun. I have found grass seed in my area that works well, so that isn't a problem. I am approximating that about 40% of my lawn is weeds/crab grass not actual grass.
I have applied weed & feed already this year. It seems to have helped some but there are still the root systems of the weeds and there are definitely WAY too many to hand dig up! Here is my question:
should I overseed (using a power overseeder) water, fertilize, etc. this year and see what happens
Is the weed problem likely to continue and new grass will not overpower the weeds (i know this may not happen this summer) and I should just plow it all up, and completely start from bare dirt with new seed.
