At the moment, the only thing that might help is giving them shade from the intense sun that is prevelent at this time of year. That will help prevent further browning. It's a universal aid no matter what the cause for early spring.

Water ONLY if it needs it (rarely in spring).
DO NOT fertilize, until new growth starts on its own. That will be about May.
If it is in a very wet spot, think about ways to drain it, and act now.

Thanks Rick!

We've had plenty of rain over the past couple days, so I'm not worried about watering them, but I never thought they'd need shade. They're right next to a concrete walk around the pool, so it's usually really dry.
