New Disease Killing Sabal Palms

This new killer disease started with the Phoenix palms, then moved to Queen palms and now the PRELIMINARY data say its killing our state tree the Sabal palm. This is devastating news.

Sabal palmetto (cabbage palm) in Manatee County have been diagnosed with a lethal phytoplasma disease. PRELIMINARY laboratory analysis indicates that the phytoplasma that causes Texas Phoenix palm decline (TPPD) is also causing the decline of the cabbage palms. A pdf has been posted on the FLREC web site. The link is http://flrec.ifas.ufl.edu/palm_prod/pdfs/Sabal-palmetto-Infected-with-Phytoplasma-in-Florida.pdf.

If the link above does not work, go to the FLREC web site at http://flrec.ifas.ufl.edu/, then click on “Plant Pathology”, then on “Palm Diseases”. The pdf is the 8th document on the list. You will also find on this page a link to the pdf with directions on how to take trunk samples for phytoplasma detection (http://flrec.ifas.ufl.edu/pdfs/LY-TPPD-Trunk-Sampling.pdf).

This is going to be an extremely difficult disease to diagnose early in the disease process. Overtrimmed palms and improperly fertilized palms in the landscape will show many other symptoms that will be unrelated to this disease. Even palms in natural settings have nutritional symptoms that will be unrelated to this disease. In other words, there are various reasons why cabbage palms will not be green all the way to the bottom of the canopy, and those reasons may have nothing to do with being infected with a phytoplasma!

The entomologist at DPI who was already beginning to investigate potential insect vectors associated with Phoenix species with TPPD will expand that survey to include cabbage palms. No one expects that identification of the vector will be achieved quickly. This will be a very long-term project.

Have you seen any Sabal palms with these symptoms???

A very good guide to beginning gardeners and arborists. One thing I can't stress enough when teaching about gardening is your placement. Look for whats above, behind, below, and what it could grow to block or overcome. Happy Gardening!

Recycling helps the earth because it could save animals, it could save birds, puppies and all kinds of them. A lot of the animals that recycling helps to save are the ocean animals. There are a lot of animals in the ocean that mistake trash for food. They're eating things that we could be recycling. Check out this video: http://youtu.be/-H51E2gwXwc

Have you read Teaming with Microbes? Good book that is doing a lot to help me understand the good side of fungus and all the other tiny stuff in the soil. Who knew?

I saw several nymphs this season for the first time ever. They are some of the more bizarre bugs to have in the garden, but I hope they'll have a good effect!

We have the dog vomit slime mold for the first time in our yard as of this spring.

Thank you for this post, it is reassuring to see that what we are doing (organics ONLY) are making a difference!

Thanks Theresa, there was a host of the Slender Flattop Goldenrod, Euthamia Caroliniana, last Oct. in an open field now just knowing this species, and what I think is the Late flowering Thoroughwort, Eupatorium serotinum nearby in semishade making the bees crazy.

We have ongoing problems w/ this @ the city park where I work - I've tried rinsing the affected skin w/ hot water, which seems to help. I understand that cooking neutralizes the sting (people actually make tea from & even eat stinging nettle).

What a cool looking mushroom. I think I will take the writer's advice and avoid walking in the dark woods to find it though.

I love both the beauty berry and firebush together. Always have flowers or berries, bright colors, drought tolerant to a degree... Nice plants!

Has there been any discussion as to why the population explosion of the spanworms occurred this year? Was it related to the very dry winter and spring (eliminating many wasps) followed by heavy rains which spurred the snowbush's growth?

Great tips. I recommend that all DIYers mow tall in summer just to avoid additional pressure on struggling turf.
Organic fertilizers work well in summer to avoid excessive growth, as long as they have plenty of time to break down prior to those heavy storms you mention.

That was an important point you made about fertilizer use during this rainy time. Suggest all use slow-release fertilizers to avoid excess run-off of nitrogen & phosphorus into our waterways.

Thanks for such great details. For the 37th Edition of the Festival of the Trees blog carnival, we talked about Survivor Trees. Your post was a fitting addition to the "Hurricane" section!

I got to this page from reading your article about laurel oaks. I would love to chat with you about a problem that I am having with one of the oaks on my property- either by phone, or email. If you could oblige me, I'll send you my email address.

Now, back to reading about these orchids!

I briefly read this early this month and discarded it, but while in downtown ST Augustine I saw a palm with symptoms that could be a diseased palm. This was the other day in the plaza (used to be called the slave market). That would be a big jump from Manatee / Hillsborough County, but other palms around this specimen in the area are healthy and it has been in the ground for some time. It probibly is anouther disease or deficiency. I have been in the nursery/ landscape business for 30 years and hate to see the infections that are effecting our major trees, citrus, bays, palms, next? Craig Hartwig.
