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.

Did you ever determine what actually happened to your hibiscus? Thanks.

No. We never did but in an update I think the problem points more and more to whatever the pest control guy sprayed for carpenter ants. Never again.

Thanks. Good to know. We used to have beautiful hibiscus outside our home and never had trouble with the weather.

I do know a lot of people don't understand that chemical spraying to kill (bug spraying) is an art and requires knowledge and experience. Some people just think it's no big deal. We lived in one area where the bug guys were experts and gave more info on things they saw than we even saw ourselves. Lots of ideas and help. Then moved to another area and it was totally different. One company, guys were told to go out and they did. They didn't even have common sense to not spray around animals...when they were told not to go in a room with animals. Idiots. Those one were good on saying a whole house needed to be tented because of a certain kind of bug. That are did have some skilled pest control companies and they told us, no, the bug was a different one entirely and no tenting needed.

Hard to know at first if you got a good company.

Thanks again. All the best going forward.
