Several of my Crotons have been de-leafed. Anyone have any ideas of what it could be?

It probably could be a number of things. I bet a picture on here would help some of the people on surfline diagnosis it for you.  In my yard I have lost some to having them in a too wet and shady environment. They seem to get a blackish mold and decline, ultimately getting leafless and dying. Did yours have a black colored mold? Is it in shade?

I've had 3 older crotons, probably close to 20 years old, die in the last couple of months. Have turned black. Plan to take them out tomorrow. Not sure why, but I feel it's some kind of disease.

put coffee grounds around the base and maybe spray the scale with neem and soap...also smash them if you are patient enough..cull the herd, ya heard.

I bet is is scale.  turned my hands green squishing the bastards by running my fingers up and down the stems.  bought a bag of ladybugs at Sun Harbor.  Helped a bit.  I tried neem, didn't work that great.  Did the dishsoap with cayenne and lemongrass. That killed more. I don't know where they come from, but they continue to return.  I didn't do coffee grounds on the crotons.  Then they went ballistic on my firebushes.  I threw in the towel and sprayed them with talstar.  All dead. I don't know how long talstar lasts, but I did it when nothing was flowering. hate to use that stuff.

Black stuff is sooty mold. It grows on scale poop. Ants cultivate the scale.

Scale thrives on stressed plants.

I was wondering why the heck my crotons turned to crap. I looked under the leaves and identified it as scale too. All over my plants

Thanks everyone. I just got back to Florida from WNC last night. I had only seen them in pictures previously. Seven out of ten completly gone. Three look,like they are normal. Too strange. Genetics maybe?

i had a couple of mine get croton scale and you have to aggressively fight them or they will win. Everyday I was out there scrapping them off with my fingers. Seems like they like broad leaf croton the best and the ones that get more sun. I eventually had to break my no pesticide use policy and use blue bottle bayers systemic. That was a couple years ago. Haven't seen them since. but always looking for them. I've got some rare croton as I collected them for a long time and didn't want to lose them. As they will kill the plant.

Had a few of the wide leaf wiped out but the picasso paint brush ones seemed to do okay with what we got here. Anyone know where to get picasso paint brush crotons these days?

I find picasso paintbrush has the least tolerance for cold out of all the croton. Sometimes you can find them in the big box stores. I always buy them when I do see them. They are great. They do best in full sun also.

I may have break my no agrichem policy too! But, I'm going to try the organicide method first.

I have had great success using IFAS's recipe for "Insect and Disease Control" on aphids, scale and sooty mold recently - "2 Tbsp cooking oil + 2 TBSP baby shampoo in 1 gal water. Spray every 5-7 days. Make sure to water the day before and do not spray in the heat of the day or full sun." I had to spray for about 4 weeks in a row (I had some bad issues with Asian scale), but, it took care of it. It looks like I am getting some issues again, so I am going to start spraying again, but, I sure feel comfortable using this as opposed to insecticides. (Plus, my hair now has a real pretty sheen to it, too!)
