Hi all! I have a willow leaf fig that I want to airlayer, the top of the tree has some inverse taper that would create an amazing base for a new tree. When is the best time of the year to do this work? Thanks!

Having to investigate die back on middle trunk , & now apex is dominated by right trunk as previous years the left received damage. Warded the aphids off quickly with detergent & Castile soap

Recently got this larch and it is in need of serious attention before doing styling work. What can be my next steps to bring it back to health in our current Melbourne weather? The picture is a rough plan for future styling, but I won't be doing that work until it is growing strong and healthy?

The taller one is a swamp white oak and the smaller one is a burr oak
