Hi, I have a dwarf Nagami kumquat tree in a pot, and it has a pretty thick trunk, although there's probably 200 flower buds, it probably has only produced about 20 fruit in the end, and not very large. My friend has a smaller tree in a pot and hers produced over 100!

I noticed the tree isn't getting any bigger. I'm thinking of repotting into a bigger pot. Any advice?

Also for the soil, I got the Kellogg Palm and Cactus Mix. Can i mix that with just regular potting soil or should i just used the Cactus mix solely. Thanks....
