WOW!!! Lot's of stuff on Container Citrus Growing. Only been here a few day's and many thing to learn. Fertilizer, Soil ph, Temp, Lightning, Soil Mix. I have a list of items i will need to be successful. Which is better for Soil Mixture, Pine nuggets, Pine Bark, Cedar chips, etc?. What about the different mulches, how long do they hold up, 1,2, years before breaking down, disrupting airation, water flow to the bottom. One thing i learned form trial & error on my 2 Orange Trees i got last year. I Mixed the Container with a Proffesional Potting mix with VERMICULITE..... never will use it again!!! Acts like a spunge!! Lost one Tree to Root Rot, the other is so so. Repotted it with lots of Perlite, just have to wait and see if it survives.
