Sometimes dry browning from the edges can mean fertilizer burn. Brown spots anywhere else can be a sign of too much sun.

Just to cover all the bases, your options are:

1. Change out the soil (if it's potted)

2. Allow the soil to dry out between waterings

3. Only use time-release fertilizer, if potted.

4. Provide at least some shade for the plant, potted or not.

I've grown Hilo beauty here in Florida. It was kept in part shade (in the ground), watered maybe once a week, and fertilized with Miracle Gro liquid.

It's also sometimes called Colocasia 'Hilo Beauty', but it is really a Caladium. So you need to treat it as such. And I'd agree, it'd be best to start off again with new soil.

I Have a HILO Beauty I Murdered It By Root Rot and Knats They Hate Water I Water if from Below The Pot and Let It Drink Its Own Water It Had Babies in the Spring i Placed them In A cup Little Bit Of Water There Doing OK PENDING Im Experimenting I Think If I Placed Them and Treated it Like a Cactus only Watering From Below it Would Do Great

Whats Also Funny I Took The Plant and Took it Out the Dirt and placed it in Water it Has 5 Leaves
