Ok so I purchased a brand new house last Sept and grass was just sodded and went dormant for fall/winter. Now that spring has come I thought I would spread some fertilizer down prior to becoming active again(advise from my Sub-division grounds guy). I have Bermuda grass.....I used Pennington fertilizer and now have weeds everywhere. 80% of yard is green and golf material but the other half is patched with weeds. I mow it down but seems to come back worst!!??! Anyone have any recommendations or advice please...
