When is the best time of the year to aerate lawns? Fall and Spring? Following aeration what is the best material to spread on the lawn? I just read that spreading mushroom mulch is good. If so, how much? Thank you.

Generally the best time to aerate your lawn is between March and May to prepare it for Summer growth. However as this has passed Fall is the next best time to aerate. If you can wait till next Spring it would be of greater benefit to your lawn as it would promote better and deeper root development! A note worth mentioning here there a various opinions on timing of aeration; early in the spring may give weeds a better chance to grow and depending if it is a cold climate grass it is better in the fall. Most however tend to prefer late spring around Memorial Day! While mushroom mulch is a good amendment to the soil it should be used very – very sparingly as it is high in soluble salts which tend to tie-up nutrients in the soil preventing grass and seeds from getting proper nutrients! The best compost for a lawn would be one that was made from Nitrogen rich materials such as grass clippings and manures. The best advice I can give you is read the label content of the compost you are purchasing to see what it was derived from. A better solution would be to make your own or obtain it from a friend knowing what was in it! I have listed below several links which should give you additional information and help.
