AusBonsai

Hi Everyone........as my name suggests I'm relatively new to bonsai (about 6 years) and VERY new to this site. This question is about my (now 2) Liquid Amber's. I thought I'd lost my original small tree, so a few months ago, a very generous member of our local club gave me a well established tree. Now they are both in full BIG leaves. Do I defoliate them both now to try for smaller leaves or leave them alone? My main concern is the ever changing weather, from hot last week to wet and freezing today
