Spring comes up the Hudson valley into Queensbury in fits and starts — a warm week in April, then a frost off the mountains that puts everything back on hold. Forever Green Lawn Fertilization works with that calendar, feeding lawns when the ground has actually woken up rather than when the date says so. On the sandy soil out this way a lawn will take what you give it and want more, so the timing and the spread matter more than the enthusiasm. What we like to see is that moment in late May when a fed lawn goes deep and even while the untended one beside it is still patchy and pale. The rest of the season is keeping that color honest, feeding again as the summer turns and once more before the ground closes up for winter.
