I'm a newbie. I have a Amberweet Orange just a little over a year ago, i used Vermiculite with some Potting Soil, little did i know i ran into Root Rot using Vermiculite mixture. I repotted it with lots of Perlite and Potting soil till i coud get some Cypress Mulch. I think it is hanging on, when i inspected the Roots, saw a few new Roots when planted it in a 1 gallon Container, Cypress Mulch Potting Soil 50/50. Just wonder if it is toast or will it come back, it still has a few leaves and green trunk and branches are still bright green. I sure have learned my lesson on using Vermiculite!!
