After the second incident in the row within a couple of months and the third in a year and all three of them regarding Sabal spp, I feel like I have to use a term  such as  Sabal Sudden Death Syndrome to decribe current situation. Used term term is by no means supposed to imply some kind of disease, instead it should describe only a certain reoccuring incident of various Sabal plants dying in a very steady pattern. Namely they die suddenly (without any prior indication like withering or stunting or discoloration) and fast and they die in a way that latest rosette of leaves dies first, then meristem dies and the rest leaves of the plant collapse eventually either fast or with age. Besides all affected plants had been growing for many years in the ground on same spot. Apart from a couple cases, which occured during 2012 and of which demise I am almost sure what had been the cause, all three recent losses consist a very alarming puzzle for me. First I lost during foreast late autumn a Sabal palmetto, then during this late autumn a Sabal uresana and now is under way also a Sabal minor.

First the pictures of the dead uresana. Latest rosette of leaves has been already pulled off and meristem as well with lowest parts turned to a stinky, jelly mass. . Now there is only a freeky gap there.

And now pictures of the S minor. Note please how newest leaves are already dead and oldest spear as well. Newest spear is ok for now, but I have no doubts that it is a matter of days before growing point also dies.

As you may have noticed already, all plants are surrounded by a knee high or higher rabbit cage. Nevertheless I id find inside the protected area around the latest casualty, something evil stinking and resembling  .... a poo! (pictures below and many excuses sorry for the induced disgustion). So I seek desperately for a possible explanation, as I have more Sabal specimens planted in the same part of the garden. Could it be possible that a mamal, most probably a cat, is spraying palms with urine for purposes of territorial demarkation?  Is it possible that what I used to get rid off existing olive palms in 2012 (brand name in USA "Crossbow"), still affects after more than 5 years existing plants? In this respect I am quite sure that the two aforementioned casualties during 2012 are collateral damage because of the application of this herbicide. But after 5 years, how probable can this be? Is it further possible that organic fertilizer had been spread to close to growing point, causing thus a meristem rot?  But again why are other plants, even small Sabal specimens in pots, not affected, as I have used same fertilizer for container grown palms. Is it possible that crown rot was induced by protective spraying of chemicals against rpw? But again I have applied same chemicals on supposedly more tender Sabal specimens such as causiarum and rosei to no ill effect so far. So WHAT IS GOING ON? Please help...

I am sorry, konstantinos:(.

I don't know what is happening. My small experiece with Sabal is they are slow growers,but always healthy with no care. In my old garden i have mexicana, uresana and causarium and they are growing healthy with no water, feed in a place with hot Summers and cold Winters. For me, Sabals are like stones.

For my experience working in gardens, the cats explanations is the most probable. Cats urine is too strong and can burn plants.

After five years, the weedkiller must not be the problem.

And the organic fertilitzer, the palms must be buried in this to have damage.

The chemicals for RPW are safe if you respect the dose.

 

I hope you will find the problem.

It seems to be roots are burnt so the leaves are yellowing,reason could be due to fertz or due to insecticides(Chemical based).Even had dogs,Now their are cats of neighbours visiting our garden and do all kind of things.But i don't see any effect on our palms.

3 to 4 cats visit and being male cats they fight for territory But due to them i don't see any squirrels and iam happy.

Here are new pictures as promised. What was was looking like it was about to wither, it is now dead but still no spear pull. No more nes dead leaves but still I am not sure whether newest spear is ok, because it stands still.IMG_20180227_180151.thumb.jpg.fb71568a67IMG_20180227_180212.thumb.jpg.ce5948ab2dIMG_20180227_180334.thumb.jpg.6caf74f3d3

And the massacre goes on also this summer! New victim is a young Sabal domingensis, which WITHIN ONLY TWO LAST WEEKS, has turned from previous condition to this one.

Same pattern of decline: First get affected newest leaves and spear. Meristem or root damage?

No. I assume it might be reaction on fertilizer in my case. I know I added 15-15-15 fert around it a week before.

If it were so, I would assume first a damage of root system, which would consequently affect first OLDER leaves...
