Question about Fertilizer

[Palmfarmer]

Only thing i was able to obtain at home depot was a 17-17-17 all purpose. it says one teaspoon per 30cm, should i include the fronds in that calculation or only the trunk? How much more than recomended can i use before i start to burn things or outright kill them? Thanks

One teaspoon per 30 cm?  Seems way too little. What am I missing in this question? Is this a top coat per trunk diameter? More info please.

sorry my bad it was 3. I am basicly just wondering if it is fine to take the fronds into the calculation, or if i should only calculate the dose based on trunk height.

Wow, you're getting serious down there!

First, the nutrient ratio is good. Palms like a more balanced fertilizer, though some say that high potassium is best. (I use wood ashes in my fireplace on my palms in the ground.)

How much to use, in my opinion, varies by species. The reason is that some just grow fast, and others don't, and there's no point in feeding a slow poke a lot, because it usually won't speed it up by much and just waste fertilizer, which can also leave residue on walks, etc.

The 30cm might be referring to pot size? And are you sure it says teaspoon, not tablespoon? A tablespoon of granular fertilizer for a 30cm pot would seem about right to me.

Definitly not it says for trees apply 3 teaspoons per 30 cm of height.

for pots it says apply 3 teaspoons into the the pot. the pot should be 10 liters or more.

I was actually thinking about using the ash from my barbecue to fertilize my bananas since they like high potassium. I only use lump coal which is basically charred wood.
