So I’ve been interested in Bonsai for a few years and have knowledge on soil / chemistry of plant biochemistry. What I do lack is best times for pruning specific conifers. All the conifers I have are Pre-Bonsai , so the intention is to wire and prune to shape before spring re-pot.Right now I have 3 Japanese White pines (different varieties) , Japanese Red Pine, Norway, Pitch Pine, Atlantic Cedar, Spruce, and Juniper.
If I wired and pruned these species is September an acceptable time to do this? I know not to repot till spring to remove roots/while still keeping native soil in tact. I’ve gotten answers that it’s okay to prune anytime after growing season , so when temps drop such as in September or to prune in spring after repot. I need a direct Answer as I’ve not gotten one. So my question is what conifers can be prune and wired around September, and is needle plucking only necessary after potting as bonsai or can it be done when styling.
Also I’ve been listening to Herons Bonsai and Ryan Neil about needle pruning to lowest needle heigh on branch.
