Anthracnose is a general term used to describe diseases that result in a wide range of symptoms including leaf spots, blotches or distortion, defoliation, shoot blight, twig cankers and dieback on many different deciduous trees and shrubs.

It happens this time of the year.. You can spray with Bayer 3 in 1 if you like but most of the leaves will turn yellow and drop getting ready for dormancy period. I will usually spray before I bring them inside.

Dont get to worried about this. We are all seeing it on our trees especially with the morning dew and the cooler temperatures at night! Here comes Fall....

Thanks so much for the information!!! :)

Hi Corey!!

I wouldn't worry about them causing any problems with your other trees.

You will see this happening as the days and nights are cooler and the moisture sits on the leaves causing this fungus/ moldy spots. Your leaves will eventually drop with them going into their semi dormant period, so they will start to yellow and drop off. All normal for this time of the season!!

Im getting mine ready to bring in this week too!!

I'm with Laura on it. Some are more prone to it than others. My Kimo will get it fairly routinely while others right next to it are just fine. I have used neem oil as a preventative treatment with reasonable success during early growing season.

This late in the year I would not treat specifically for it but if you follow Laura's winterizing practices then you will be spraying 3in1 in the very near future anyways.

My plumeria has these same black spots —- I’m in Florida and it’s the first day of summer so I don’t think cooler temperatures are the cause — can you explain and offer suggestions ?

Anthracnose can happen during summer too. Particularly in wet humid environments. I would treat with neam oil or 3&1 as recommended above.

Thank you for your response and advice. I am going to try the neem oil — fingers crossed.

I will also add that I do have a few leaves with more black spots that are in an area that doesn’t get direct sun and it’s been raining a lot here in Virginia!!

Its not something that I worry about since the leaves will eventually drop and I can move those tree to more sunlight to rid of any new fungal spots ...

i only use Bayer 3 in 1 when I have such a huge infestation of spider mites etc. it’s somthing that I do think about like PHalanx mentions and I do let Mother Nature work with the problems in the yard.. if using Neem Oil, please don’t use in direct sun and wait to apply when it’s a cloudy day!!

Sometimes we are to quick to assume it’s something awful and I believe that we need to just let Mother Nature work her ways until you feel that it is necessary to step in . Go with something you feel that will help and I also like organic, but when it does get totally out of hand then I will go with something more powerful. With that said, I didn’t use the Bayer at all for problems last year ( until I sprayed to. Ring them inside for the year end) and I still have not used it this year as well... Think about what you think is a problem and then decide. Here is a picture of those spots that I’m not worried about.

If we looked at every tree in the forest or even at a nursery, you will probably see a blemish here and there!! ;)

just move some trees around to give them more light and air movememt!!

i hope this helps!!

I have never brought my Plumeria inside for the winter. How do you do that? Do you just pull them out of the ground? And put them in a dry place inside or do you leave them in dirt?

What zone are you in? Does it typically drop below freezing where you are? If not, just leave it in the ground. If so, yes you can dig them up for the winter. They actually come up pretty easy as all of the roots flare out. I grow all of mine in the ground and dig them up for the winter. I like to prune all the roots back, let the cuts dry and then pot them up with barely moist(almost dry) soil and store in the garage. This allows the roots a head start to regrow in the spring before I re plant them.

.. Input!

Here I’m again with my black spots. Is it the same as above or is it something different?

Considering your area of concern is primarily along the leaf edge I’m initially thinking it’s some sort of insect or mechanical damage (wind, rubbing, movement, etc.)

Thanks a lot, but there is no wind since they are indoors, no mechanical damage either so I’m lost

It could be from some time back. Just considering the area of concern is primarily on the edges I am still not thinking its anything serious. Continue to keep an eye on it and if it worsens then it should be investigated further.
