Yeah, I feel you, Yayi. Raining every day here with these blasted tropical storms constantly rolling through. I finally gave up and brought in many of my orchids, all of my adeniums, and put them under lights. Even my hibiscus so I can enjoy the flowers instead of watching the rain rip up the blooms. Awful drought last year is working hard to flood us out this year!

Patty i must be doing something wrong. This is the 3rd bud that has failed to bloom. Too much water, not enough? Too much sun, not enough? I'm so discouraged.

I use Foliage Pro every other watering and there is Osmocote slow release in the soil along with lime from the original mixing of the 5-1-1. The leaves look strong, green and sturdy. They are only getting morning sun right til noon. I'm wondering if maybe that's not enough. It's also been very windy, not sure if that contributes to stress. I will read up on everything you suggested, so stay tuned for the inevitable follow up questions ;) Thanks Patty!

Yes, could be lack of sun with too much rain. So the fungicide may be your best bet. Sounds like you are doing well with the feeding. Not much you can do about all the rain unless you can move it indoors and put it under lights. Sometimes relocating them can be a whole other stress if you jump from high humidity to suddenly much lower, though.

Would you mind suggesting a product for the fungicide??

I did. Copper sulphate - any brand that is a liquid spray for plants. If you get the crystals to dilute it yourself you'll have to look up the ratio so it's easier to just buy it already made into a liquid. Bonide sells a bottle for like $15 but I found some other brand at Home Depot for only $7 and it works well. Brand doesn't matter as long as it's copper sulphate in the correct dilution to use it as a fungicide. It can also be used to kill plants at much higher concentrations so you don't want those.

There are a lot of other things that can be used as fungicide sprays as well so Google around or hit your local garden centers. Sulfur works as well as many other things. Just never use sulfur if you use anything oiled based as it causes phyto-toxicity. I wouldn't bother using Neem oil as packs very little punch.

Here's another one. :'(

It does have new growth though, just can't hold a bloom.

I'm apologize in advance if this is not the proper place to ask this question. I just noticed you all seem to really know your stuff. I live in Tampa Bay Florida and we've been slammed by a ton of rain. I read your other comments and think that may work for what I'm experiencing. I just wanted to share a photo or two to make sure that what I'm seeing on my Hibiscus is the same. Any assistance you can offer is greatly appreciated. I am new to this plant, but my mother-in-law loves them, so I would very much like to save them for her if possible.

That may actually be insect damage, John. But hard to say for sure. My best recommendation would be to look up your local county agricultural extension office and swing by with a leaf from your plant and ask them. They can look at it in person and give you a better answer than I can by looking at these two photos. Are they dead little tan spots in the leaves or texture?
