ALOHA,
I'M NEW ON THE ISLANDS AND NEED SOME HELP WITH MY LAWN. THE AREA THAT I LIVE IN IS EXTREMELY HOT ESPECIALLY NOW DURING THESE SUMMER MONTHS. MY GRASS WAS GREEN AND WALKABLE. I'VE NOTICED WITHIN THE PAST TWO WEEKS MY GRASS IS TURNING BROWN IN SOME AREAS AND THE SOFT GRASS I ONCE HAD IS nOW HARD WITH ALOT OF KUKUS (POKEY CIRCLES) IN IT. CAN YOU TELL ME IF I'M DOING SOMETHING WRONG HERE.
SHOULD I BE WATERING IT EVERYDAY NOW DURING THIS EXTREME HOT WEATHER OR AM I SUPPOSE TO BE PUTTING SSOME EXTRA NUTRIENTS (SOIL ETC,) ON IT. YOUR QUICK RESPONSE WILL BE GREATLY APPRECIATED. THANK YOU VERY MUCH.

Daily watering isn't recommended, even it hot weather. Your goal is to water deeply but infrequently to encourage deep rooting so your lawn will be less susceptible to drought and heat. One inch of water per week is usually all a lawn needs. You can water twice a week when it's really hot, but once a week will usually suffice. The browning areas can be the result of cool season grasses dying out in the heat (they will green up when the temperatures cool off), dog urine, insect problems or diseases (from overwatering). I can't diagnose the problem without seeing it so I can only suggest you visit a Master Gardener clinic or cooperative extension office with a sample of the dead lawn. They can do some microscopic inspection and at least rule out common causes. In the meantime, water your lawn deeply and plan on feeding it in September or October when the weather cools down a bit. It should green up in November and December. If you keep it on a regular feeding and watering schedule it should regain its health. If the brown spots persist, dig them out (this fall) and reseed the bare areas. Best wishes with your lawn!
