I'm about to use the Bayer Granules for the first time. Will it hurt trees if you apply a little too much? Directions say to use 2 teaspoons for a 1 gallon container. How should I judge how much to use on small pots? Most of my trees are in pots smaller than 6". Does anyone have experience in using the granules? I would love any usage suggestions. I don't want to damage my trees. Posts on here seem to have success with using the granules. I just couldn't find any posts with how much people use. Also, does it really last 12 months? I would appreciate any help. Thanks!

Look at the size of your pots vs a 1 gallon container. If its about half, use 1 teaspoon. If its 1/4 the size, use half a teaspoon etc

I have always just used the liquid 3/1 but it's always better to start more deluted when trying a new fertilizer treatment

I have used the Bayer granules on my roses since 1995, and it's a great product. I would suggest the '2 in 1', r/than the '3 in 1', which contains a fungicide that would be bad for the mycorrhizae. In my experience, no, it does not last a year--three or four months would be more like it. If you put the granules on the surface, and water normally, it would be unlikely that you would over-fertilize.
I would suggest the same approach that I use when cooking from Korean recipes: use half of what the recipe calls for, see how you like the result, and work up from there.
I am very new to bonsai, but I can attest that with roses, the systemic insecticide works wonders, especially with any kind of aphid.
Your mileage may vary. Taxes, title, and dealer prep are extra.

Thanks for the responses! Anyone with experience with granules with bonsai would still be helpful. Thanks!

I use a mycorrhizae treatment on mine and have used 3/1... totally didn't occur to me until now that I was probably killing off my treatment when I used it :oops::eek: good thing I don't use it so much

The fungicide portion of the bayer product should be more-or-less safe for beneficial fungi. It is a pretty narrow-spectrum fungide. When in doubt. I consult THIS handydandy spreadsheet http://mycorrhizae.com/wp-content/uploads/Effects-of-Fungicides-on-Mycorrhizal-Fungi-PDF.pdf
