Answer: Lawns should be fed in April, June, September and late November. I find that the fertilizer goes on sale at just the right time for application so watch the sales ads. Crabgrass control should be applied in February or March, before the weather warms and the seeds sprout. Grub control should be applied in late August unless you're using one of the time released types. In that case, you can apply it now.
