The leaves can yellow from too much heat and sun, but it's not usually damaging to thier health. You can cut off the most unattractive branches. Some shade in the hottest afternoon hours would be appreciated. If drought stressed, it probably appreciates the thorough watering, but be careful not to overwater. They prefer well draining soil and to dry out a bit between waterings.

Thanks, W. Any tricks to get the fronds back to green?

Once sunburned or water stressed, the fronds will not green up again. The Sago puts out a new set of fronds from the center of the plant only once or twice a year. For now, shade cloth or a shady location, NO fertilizer, keep the soil moist but not wet. If possible plant it in the ground where its roots will stay cooler. Sagos grow very slowly so your recovery will be slow as well.

Trivia fact - Sagos are not really a palm at all, but an ancient plant that is closely related to pine trees. Individual plants are either male or female and if you're lucky eventually they will flower. The single male flower structure resembles a pine cone and is located in the center of the plant.

Good luck.

Thanks for the handy info. I did thoroughly soak it last night. I'm having some work done on my yard so it will be in the ground within the month. In the meantime, I'll keep it out of the sun. Good to know about the fertilizer.
