Sick Sago Palm - Droopy Fronds
Hi. I have two Sago palms (maybe 8-10 years old?) next to each other in my yard. One is in a pot and the other is in the ground. The fronds on the potted one have become very droopy over the last week - and they are very flexible where they attach to the base; I can move them up and down a lot. The color still looks OK though. A few days ago I started watering it a lot (daily) thinking it was drying out. Upon further investigation, there was standing water in the pot and it was not draining properly. I've since fixed this (removed water / made sure it's draining) but I'm wondering if it might have root rot or if there may be other cause for this behavior. Pics attached. Any ideas / suggestions about what to check and how to mitigate / restore would be greatly appreciated. Thanks!
