Q.Sago Palm yellowing
My Sago Palm has prospered for at least three years, but the most recent batch of fronds has suddenly begun to yellow and shrivel. The plant is watered by a sprinkler system that has not changed for a year. We have been in a dry spell however.any suggestions would be great.
It's always best to water plants directly at the root zone than with sprinklers so that water is not wasted by watering unnecessary other things and plant transpiration. Watering from above can also cause and spread fungal diseases. The photo of your sago does look like an issue from watering. These articles may help
