June 1 - July 15
Grass should be green and growing nicely by now. A granule fertilizer high in nitrogen for growth and added iron to enhance the color even more will be applied. Ideally few weeds should be present, however some weeds may present themselves and will be addressed as needed by either spot spraying or applying a broadcast spray. Dollar Spot Disease may appear during this time. It is prevalent during with hot and humid climate. The nitrogen included in this application can be used as treatment for such disease. If it does not fix the issue or dollar spot is severe a fungicide application may be needed.
Mow! Grass will be growing fast now and will need to be mowed at least weekly. Maintain a mowing height at 2-3 inches and mow frequently enough to not scalp and cause a brown look to your lawn. Scalping the lawn will cause excessive thatch, damage to turf, and cause openings in the grass canopy. All these factors will promote weed growth. Most likely irrigation will be needed. Irrigate in the early morning hours. Ideally a lawn will need 1 inch of water by either rain or irrigation every 5 days now. Placing an aluminum pie pan in the yard while running sprinklers is a great measuring tool. Do not water in the evenings. This will keep the leaf surface wet overnight and promote disease.
