I bought this poor little guy about a month ago from a garden show and a reputable vendor. It was green and perfect when I bought him.

It's a Gmelina philippensis or parrots beak.

Now the leaves are yellowing, curling up, and falling off, It's dying.

I've been keeping it outside, in mixed shade/light space. We've been getting a lot of rain here and it's been much cooler than normal for summer but not cold.

I brought him inside yesterday to see if it helps.

Any recommendations would be great.

Thanks!
