Help with problem on sago palm

24 posts in this topic

Hi all. recently I noticed spots on my potted sago palm and some yellow fleckering on the tips. about 3 weeks early the palm was blown over and knocked outside its pot. so i wonder if it could have caused some damage to it roots or maybed something else. anyway could it be tip blight? but that wouldnt explain the spots. please help me. thanks

Are they very small spots, almost all on the underside, if so then it's asian scale, Ed

Fungus I would say, here we have to keep them sprayed with Neem oil, to keep fungus, and scale off, btw, it's not a palm tree, Ed

Since this is a cycad discussion, I am moving it from Discussing Palm Trees to the Tropical Looking Plants sub-forum. And incidentally, I had the same problem with my Cycas revoluta (a.k.a. "sago palm") and I ended up throwing them all away. This is a tough one to fight.

Hail did the same thing to mine as well. Looks identical to that.

I'd say hail too. I have a few plants that look like that after our hail.

You can just let your Cycas do its spring leaf-flush and these will be largely forgotten, if this is just cold damage or some other relatively benign exposure issue. To keep any scale or other critters off the plant now and in future, follow the recommendations of Tom Broome (president of the Cycad Society and expert grower), basically to make a "tea" of coffee grounds (you can also just use brewed coffee) in a spray bottle and spray the bottoms and tops of the leaves. Then take grounds and put them in the crown of the plant as well as completely surrounding the base of the caudex (trunk). Apparently, the "crawling" stage of the Asian Cycad Scale (and most scale for that matter) have to crawl up the plant from the ground into the crown, and the coffee will basically annihilate them. It's a natural and easy method of fixing what was a nightmare problem a few years ago, and is both an excellent preventive and can be a great mulch as well. And completely safe (except to the scale of course!). See Orlando Sentinel article for an overview.

If this is damage from hail I am obviously taking back my comment, which was based on the assumption that this is Asian scale.

I was going to say cold damage as well, because sometimes, a very light frost will make that pattern. First of all, if it was scale, you would see scale insects somewhere, and the yellow spots would be where they sucked out green stuff. All this was, was yellow spots. If it was a fungus, somewhere, on at least a few of the spots, you would see little black spots within the yellow spots. That would be the signs of spores on the fungus trying to make more fungus. This showed just a slight amount of ice damage because the spots were so separated. The brown ends are signs of mechanical damage, where each leaflet probably got bent back. If you look close, you will see that the leaflets are brown in a straight line where they got bent.

On the coffee, that article came out in the Sentinal before I wrote my coffee article, so for more information, I'd also read this article, which is in the Cycad Society website:

http://www.cycad.org/documents/Broome-Coffee-2007.pdf

I have learned a whole lot more about using coffee, even since I wrote the article. I containue to experiment with it and it has helped a lot when I am growing my hot pepper plants. One fast mention, the softer the plant in general, the better it will take up the coffee systemically. This menas for me, that I can grow a pepper plant for the entire season, insect free, just by potting them up with 10% used coffee grounds in the soil. I have 30,000 plants and about 500 species opf plants, and I haven't needed to use any store bought pesticides in almost 6 years now. (except for when I am forced to, by USDA when I ship plants to other states)

Hello, I found this site after finding the same yellow spots on my 3 sago's !. I was very anxious as last year I dealt with fizzle top and now this. Strange that you mentioned hail, because 2 weeks ago we also had a freak hail storm. There is nothing on the under side of the the frawns but does look like lite white fuzz down on the the stem coming out of the cone. I think I will treat with Neem oil spray just in case, should not hurt anyway. My Sago's are my front lanscaping center pieces and I really am attached to them.

Welcome! Glad you found the site. You could also try the coffee that someone else mentioned in the post. Im watching my sago for pests still havent found anything to worry about yet just the hail damage. Im gonna just wait it out and see. Wish you luck!
