My hibiscus tree's leaves are turning yellow and falling off,I've tried everything it isn't over watered.

Question:There are no bugs on it it just started happening it is in a pot on the porch facing South it was thriving then all of a sudden its leaves fell off it has buds and use to have lots of flowers.

Answers:
Hibiscus are very sensitive plants. If your plant has been under stress from too much or too little water (especially during warm/hot weather), they'll lose their leaves and buds.

The soil should not be allowed to dry out between waterings. It's recommended that you place them in a soil rich in organic matter and place a mulch on top to maintain a constant leverl of moisture. Also...if your hibiscus is being exposed to too much sun, you may want to consider moving it to another location.

Hope this helps solve your problem! GOOD LUCK!
