The silty soil in Watertown lawns holds nutrients well but can compact easily. Core aeration helps prevent this issue while improving water penetration. Your soil's higher calcium and potassium levels support strong grass growth, but you might need targeted nutrients for optimal health.

Having the fertilizer product shipped
Having the fertilizer product shipped to your front door makes its very convenient, saving a trip to the hardware store every couple of months. I really liked the soil test as not every lawn is the same and since Sunday creates a plan based off the results, it feels tailored than just regular fertilizer you’d get at the store. The service also takes the guess work out of remembering when you need to fertilize again, since the Sunday service ships your fertilizer right before you need to spray.
