Answer: Grass will green up naturally in the spring as the season progresses. The best green will be achieved by proper care, including fertilizing and possibly lime if needed. The only way to tell the optimum amounts is to run some basic soil tests and then amend the soil as indicated by the test results. Fertilizing in the fall is one way to assure quicker greening in the spring. Next, mow often to encourage dense healthy growth. Never remove more than one third the grass height at a time. In spring this can mean mowing more than once a week. Take care not to overfertilize as this creates overly lush grass that is prone to pest and disease problems and also grows even faster than normal requiring even more frequent mowing.
