It sounds like a nutrient deficiency-magnesium most likely. But they also get potassium deficiencies etc. Using high nitrogen fertilizers is a big no-no and the cause of the problems. Nitrogen speeds the growth and accelerates the need for the other nutrients that arenÂt available. Use a slow release fertilizer. IÂm sure youÂll get other great advice. IÂm a palm novice.

Queen palms need a heavy dose of minor elements. These minor elements are sorely lacking in most florida 'soil'. If the new growths are smaller brownish and frazzly looking then your palm has what is called frazzle top. This is caused by a lack of magnesium and manganese in the soil. It probably can be salvaged, you need to get some(3 lb bag)of both items (manganese, magnesium) melted in a 5 gallon bucket and pour the solution around the palm, stay within a a 3-4 foot radius of the palm as this area is where roots are most concentrated and repeat monthly. When you see a regular green flush of new fronds, then you can just start using palm special fertilizer. At that point you should be in maintenance mode and if memory serves me correctly the right dosage is 1 lb per inch of trunk diameter applied (spread out evenly within the canopy drip line) at least quarterly.

Thank you very much for your replies :)

I figured picture is worth a thousand words, so here is my sick one -

and close-up where you can see the new growth is green -

and the healthy on on the other side of the front door that gets the same watering, fertilizing and light conditions -

Thanks for posting the pics, looks like the older fronds have some frazzle top. It does not seem as severe as I imagined it. You may not have to do the manganese and magnesium, but for sure get the best palm special fertilizer and spread at 1 lb per 1 inch of trunk diameter. HDepot has the Lesco variety palm food and it has worked well for my palms over the years. They carry a 50lb bag and as u said you have a few queens, the bag should not last too long... As a general rule of thumb I find that the the best fertilizer for ground (not lawn, which requires higher nitrogen) granular application is the palm special. If you review the list of elements you'll see that the minors are substantially higher than other types of fertilizers and this is strictly 'cause palms need the extra minors to do well.

I'd give them a bit more manganese and magnesium right about now and a regular spring fertilizing with "palm" fertilizer.
Wouldn't hurt to spray them or even fertilize them with some "palm" minor elements. Found in a bottle at your favorite box store. Spray the leaves or drench the roots. Good time of year to do this.

I have a drake elm root growing under a brick walkway and the bricks are starting to heave. I seperated the root from the tree and now the root is growing leaves. How do I kill the root without disturbing the brick walkway?
