Q: If our soil is bad, what should we do? Will application of lime and aeration do the trick?
A: A soil test is a good first step. If your soil is depleted or compacted or shows telltale signs (excessive weeds, moss, etc.), it may need more work. Healthy soil should have a neutral pH and be well aerated. Compacted and acidic soil favors weeds. Neutral pH, aerated soil favors grass. If there has been construction that took away your top soil, if you have subsoil rather than loam, or if your current lawn is mostly weeds, put down 2-3 inches of new soil and top-dress with 1/4 inch of screened organic compost.
