My grass lawn has never done well despite a lot of care by my landscaper. Towards the end of last summer, I asked him to try placing some microclover seeds into an existing lawn with which have done surprisingly well (I like the way it looks) but there are still some struggling grass, a few other weeds and bare spots (I think from grubs). . My landscaper is not familiar with microclover and he just placed grub killer and corn meal weed killer: 1. How long should he wait before adding more microclover seeds. 2. Any special way he should add them (he said he was going to overseed with the microclover). 3. Any other thoughts. Thank you.
