I am interested in AutoPot specifically for growing citrus trees (lemon, key lime, rubyred grapefruit, pomegranate). I have some concerns about salt buildup though using AutoPot for small trees that live forever. Especially because I also would have the pots outside during the warm season.
I have read that over time salts will build up at the top of the AutoPot. It wouldn’t be a big deal for plants that are destroyed at harvest time, but these trees essentially should live forever. I also read that washing the salts down could kill the plant, which a heavy rain would certainly do when the pots are outside.
Has anyone ever grown citrus trees in AutoPots long-term? Are there different things that need to be done for that (e.g. growing medium, type and electrical conductivity of nutrient solution, flushing method, etc? Or is it just not a good idea for an AutoPot?
Hi Ronald,
Personally I have grown citrus plants/trees in AutoPot for many years in greenhouses and outside with no issues at all, the growth is fantastic, we simply used a citrus feed and have never encountered any issues with salts and rain washing them down. We would suggest that if you have AutoPot outside that if it rains heavily and for longe periods simply turn off the reservoir and then turn it back on when the rain has subsided and the solution in the tray has been consumed.
