I would give the newly collected WC chem fert (like M gro)--if its in a free draining substrate (add Perlite to soil!)--and if it does not have a huge muck ball, if it does, avoid the muck ball some. Also foliar right away--they love this. Managing green on new WC depends on vigor. Some gro right away others don't, Sometimes they push growth all in one area and the weak foliage benefits from that having some of the leading growth tip cut after they have grown for 2 weeks. If tree grows ramp fert. If you cut, stop late summer/early fall to assure it settles. This is a nice tree! I would nurser lower wimpy foliage for the future.
