Question
We are currently looking to invest into an irrigation system. Which system is better Toro or Hunter Sprinklers? Also, I sewed some grass seeds in October. Since planting the seeds, the clovers have started to grow. Therefore, when should I start to put a pesticide on grass in order to kill the clovers? In addition, there are spots in which the grass is not growing well. If the grass does not flourish, should I aerate the spots and plant more grass in the Spring?

Answer
Irrigation system: Both companies are solid.  I think you should defer to the installer as to which brand they prefer, and as to what kind of warranty they offer.

As for the pesticides, definitely wait until the grass has grown in fully and maturely. It may take until next Spring, but that's okay.  Young seedlings will be particularly sensitive to any chemicals, and you should not put it under any undue stress.

Definitely reseed the thin areas next spring.  You'll have a bit of a battle on your hands with weeds next season, but you can always address that with the fully mature lawn.

Good luck!
