What is the N-P-K ratio?

I bought this last year and the package says 8-15-30

I have just planted an oak ( miami ) ( 100 gallons pot ) the tree is about 16 feet height. is it recommended to fertilize it? when and how?

The thing to remember the most is regardless of size and type of plant, is not to use to much. It can stunt the growth or flat kill the plant. With your miami tree in a pot the amount would naturally be less, I would strongly suggest you talk to a local nursery ( not florist) about the amount you should use for the the size pot you have. My trees are in the yard so here is what the instructions said to do. You are to make a hole roughly 6" to 1' down at the drip line of the tree and add a 1/4 cup of fertilizer all the way around the tree, the holes should be about 2 to 3 feet apart. This will encourage the roots to spread out and down to make the tree more stable when full grown.

I am planting a 3 ft tall shumard oak. how would i apply this? can i mix in the soil i am using for backfill?

sorry for the wait, if you have used it yet. For best results put some in the hole before you put in the tree. Then at about 3 to 6 feet away from the tree dig down about a foot and put some in the hole , do this in an box shape around the tree. this will help the tree to spread out the roots for better stability. And the deeper you dig down to put the fertilizer the deeper the roots will grow to find it.

can i use this on a newly planted oak cutting.

Yes it can be used on a newly planted tree, but is applied in a lower dosage.

It WORKS!!!

I am now a believer. My 3 trees were always just barely growing for the past 7 years. I’ve seen more growth since I fertilized them for the first time early Spring. They have NEVER looked better. Even the trunk looks bigger.

Need auger to use according to instructions

It’s too early for me to know how well this fertilizer works. I am uploading an image of the usage instructions so you can prepare better. I had to order an auger for my drill after receiving this product. I also think the amount in one bag may be insufficient for a mature oak, so I ordered more fertilizer, paying a second time for shipping.

Big improvement fast

Last summer we believe our oak in SW Florida was hit by lightning. All leaves started Turning yellow and fell off. This tree is so important to us for shade on our lanai. All winter (or what we call winter) it was totally bare while my other oak looked beautiful. I was upset thinking I might have to cut it down. Tried miracle grow and iro n nothing worked. Thought I would make one last ditch effort and get this stuff. Poked the holes around tree and filled holes. That was 3 weeks ago, Not beautiful yet but actually growing leaves!!!! We will see what happens from here.

Good Product

This fertilizer seems to have done well giving my tree the nutrients it needs. It has grown well during a drought with daily watering.

one tree looked terrific and the second seemed to improve

The order was on time and the product was what I expected. After I applied it there seemed to be an improvement to my dogwood trees. This was a month after I applied it. I was so surprised I ordered another bag. These dogwood have been struggling for some years. I lost one and another is losing leaves. Shortly after applying, one tree looked terrific and the second seemed to improve. So the short term review is very good. Long term is yet TBD.
