i had gotten a red and a white from Home Despot for $2 each a few years ago.
the first year i got very few fruits, and while none were great
the red tated much better.
the next year, the white was absolutely amazing.
sweet, soft etc... so much better than the Mex cream i have also.
we just had a freeze a couple of months ago, and both were unprotected.
they are coming back, but only the lower part of the tree. it killed all smaller branches.
i dont know if i will even get fruit this year.
i dont know what was the difference in taste.
the white was planted on sand, though i did add lots of mulch,
leaf litter, and fish emulsion.
maybe it just took that long for the soil to get better ?
But the red didnt taste any better, so, i dont know, maybe the white just had better genes.
