How to use Pro AGLIME to use on potted figs?

I went to Tractor Supply looking for some pellet lime for the figs. They could not find it. I bought some powder AGLIME. If I use this on potted figs about how much do you spread for a 10 - 15 gallon pot? Is a tablespoon enough?

I was going to use raised bed potting soil, maybe a little sand and some finer shredded bark for the fig pot mix. I didn’t buy the raised bed mix, but it is like these.

I used that same lime at 1 tablespoon per gallon of homemade potting mix for apple rootstocks when potting up. I used Pro Mix BX and added 1/2 inch screened bagged pine bark mulch. Also added 1/4 by volume #4 perlite. A lot of lime runs out of the mix when first watered but enough stays there for a full growing season in 5 gallon pots.

OK thanks.
