We left for a week. My large potted hibiscus was fine when we left. Green, healthy, blooming. I gave it a good drink before I left like I normally do. I got back and the entire plant is yellow. Leaves are soft but yellow/brownish and drooping. The soil is damp, The rain gauge said we had roughly a 1/2" of rain while we were gone but it did get pretty hot for a few days (mid 90s) while we were gone. I scraped a stem high up and it's still green under the bark.

A wild card: We had an exterminator out for carpenter ants right before we left. Could something he sprayed have shocked the plant?

Lastly is there anything I can do to help this plant? It's been so reliable over the years. I'd hate to lose it.

Thanks.

Ants like the hibiscus nectar. A simple step to eliminate would be to ask the bug guy "by the way, did you spray the plant by the door/whatever". He may well have seen ants and sprayed.

Funny thing is, I have known several people who spray and do not know what they should not spray on. I lost a nice little herb garden that way and had to start one elsewhere because of the spray in the soil. The crazy guy thought they were weeds.

Lack of sunlight can cause overall yellowing of the leaves.
