I tried to post photos but it doesn't seem to be working, do they need to be in a certain format? Anyway, plants were installed on April 4th - mostly 1 gallon, 3 gallon and 5 gallon containers. Most are now looking a rather sickly yellow or brown and leaves are falling off. The installer put 2 gallon emitters on just one side of root ball, in some areas he put straight spaghetti tubing w no emitter to one side of root ball and set the system to run 1 hour per day. Please advise.
