Q.orange tree leaves are yellowing and curling up
I got a citrus orange tree and the leaves are yellowing and curling up. I water it every few days because it is hot in Florida. It gets 6-8 hrs of light, and has already been fertilized. What am I doing wrong?

I believe the tree needs more water.
If this is newly planted you will need to water every day for the first two weeks. Then you can cut back but always check the soil moisture.
Mulching with 2 to 3 inches of hardwood mulch can help with evaporation.
