In the next week or two, I plan on aerating my lawn, then topdressing with a good supply of finished compost, and then putting down Lesco Dimension as a pre-emergent. Question is should I be doing all of the above in the order specified above? or would it be better to aerate, wait a week, put down dimension, wait some time, and then spread compost? Would love thoughts on ordering the above, as well as any waiting periods I should have between steps. Not sure if it matters that much, but wanted to get the thoughts of others.
