Boron deficiency in coconut palm

[pj_orlando_z9b]

It appears my coconut, although recovering well, is showing symptoms of what I think is boron deficiency. I put down a balanced fertilizer in April 1 and again on July 1. I've had almost 35" of rain since May 1 in Central FL so maybe I need more? Any recommendations on a solution?

My newest fronds and something I found on the web to compare.

Classic hook leaf?

Don't know if this will help. However late last year I switched to this fertilizer: (it contains boron). And don't forget the NaCL. 5 tablespoons full at that age.  Salt is their no.1 fertilizer.

I switched to Carl Pool in June and I just saw it does not have boron. I wonder if I should put a solution down just for boron.

Since boron is a micro/trace, you would want to add a very, very minimal amount.

More over than boron, I would apply salt to your coco. Do you have a complete shot of it?

Took this tonight. I add manganese sulfate when I do regular fertilizing since my soil is very low in manganese. I've dealt with frizzle top on some palms.

In the past, I've sprinkled some Borax laundry detergent booster over the root zone of various palms that appeared to have boron deficiency. But had to just guess at how much to use. I was told to use Borax by the University of Florida, but they didn't really tell me just how much Borax to use. In any event, my palms grew out of the Boron deficiency. This was post 2010 freezes.

Boron deficiency indeed. Last year, after several days of heavy rain, a few of my palms showed symptoms of boron deficiency. I corrected the problems with "ESSENTIAL MINOR ELEMENTS Granular Formulation" —the liquid formulation doesn't contain boron, but I still use it to prevent manganese deficiency.

I was also using Carl Pool Palm Food, so I switched to Palm Gain

I actually bought and applied Palm Gain this morning cause they had the highest concentrate of micronutrients including boron and manganese.

Yeah, I'm hoping it was due to the heavy rains last month. Then we went dry for 2 weeks in July which may have allowed the boron to not be leached as rapidly.  It looks at least minor and treatable rather than a severe problem.

Southern Ag Essential Minor Elements in granular form is great and most cost efficient in 40lb bags for about $40. If you get a lot of frizzletop after winter you can find manganese sulfate in 50lb bags for a much more reasonable price that the expensive little bags at the BB garden center.

Whoa! I have far too many palms to feed to pay $16.98 for a 10# bag of Palm Gain. That's the most expensive fertilizer (per pound) that I've ever seen!  That equates to $84.90/ 50#s!!!

I pay $19.85 for a 50# bag of 8-2-12 palm fertilizer, to include some slow release nitrogen and potassium, with magnesium, iron, manganese, and sulfur (see bag label below).  I buy my fertilizer from a company just outside of Avon Park, Florida. They mainly cater to the agricultural growers but sell to the home owner or anyone else.

For additional  minors, I buy a liquid concentrate called Brandt Bio Master.

For all my potted palms and plants, I feed them Osmocote Plus, but I also give them on occasion 20-20-20 with minors. I buy this in 25# bag for around $24/bag. This stuff lasts me for years. My wife also uses it to fertilizer all her potted plants and roses, etc. on our lanai.

This deficiency,along with frizzletop, often happens and is displayed in many mature queen palms grown in Arizona.New fronds push out thick and heavy and collapse under their own weight.It is hard to eliminate,and was the reason I removed them from my yard.
