Our Sabal Bermudana Needs Help !

[Kris]

Dear Friends,

Here is a Sabal Bermudana growing in our roof top garden.It did grow quite fast.But last year i did forget to feed this baby with palm fertz and other nutritional supplements.And now the palm leaf fronds are yellowing bit fast & drying up soon.

Is it some kind of nutritional deficiencies or is it pest infestation ?

And this palm is growing in washed river sand and nothing else.And some of the queen palm that grw in the same medium have all perished...

And here is a old link on its repotting work :

Hey Kris

Looks like it could be a magnesium deficiency. I have a few variety of sabal's that grow everywhere where I live and they grow in sand as well. Some of them are prone to lower leaf yellowing which is a magnesium problem. Might be what is wrong with yours.

I thought K deficiency is what is associated with older leaves dying prematurely.

Dolomite lime will green it up. Sabals love dolomite lime. Before you add the dolomite, make sure to give the pot a real good soak to try to leach out any accumulated salts.

[Xhoniwaters1]

Axel your probably right. Although both K and Mg problems can be hard to distinguish sometimes.

[sonoranfans]

Its definintely K deficiency but it could also be Mg deficient. You wont get the color back on the old fronds, it will have to grow out of it. Mg deficiency looks fairly even due to the mobility of Mg in tissue, K is blotchy, and that is what I see here. Because you have gone so long in a wet environment without fertilizer, you probably have multiple deficiencies...

Here is a picture of one of my Sabal's I just gave a generous dose of Mg. Hopefully I did the right thing

Where I am located in have no access to fertilisers.  But I have plenty of bananas... would This work if I put bananas at the Base of the tree. With time would mg migrate to the soil? I assume that banana is a good mg source?! Anyone tried?

[PalmatierMeg]

Bananas are known as a good source of potassium but I'm not so sure about magnesium. I suggest you try banana peels to reduce a source of flies associated with rotting fruit. Also, even though you may not have bagged fertilizer, do you have a source of animal manure: chickens, sheep, horses? Manure is a natural source of fertilizer and people that use it highly recommend it.
