Root Pruning and Re-potting
Now is the major root pruning time for your bonsai trees. You can root prune and pot almost all trees now (with the exception of pines and cedars).
Keep feeding your bonsai throughout autumn. Diluted liquid fish emulsion is my preferred fertilizer.
Look over your bonsai for any signs of pests and treat with the appropriate spray.
Keep an eye on those bonsai that you have already wired to ensure that the wire doesn't start biting into the bark.
