Thanks everyone for the kind words.
Richie I haven't noticed any doubles on mine, it's a 2 yr old tree.
This is what I've been feeding and using for potting mix - 4 part agway pinebark mulch 2 part peat moss 1 part perlite 1 part compost, lime ,couple of handfuls of osmocote plus and the gross part; lots of buried seafood waste i.e. Fish juice,fish head,bones, guts, crab shells,shrimp shells, clam and mussel shells.just about anything from the sea, make sure to bury it deep ;)
Brett when you emptied the reservoir and let the mix dried up a little it's not that heavy at all. You could easily move it with a regular handtruck but I have a 600lb one made for moving drums just in case.
Vito my friend definitely next year!
