@Leo in N E Illinois ,
lots of sun and encourage many branches. With just one
defoliation a year [ it happens naturally in nature [
you can have 1 to 1/2 inch leaves.
Also more leaves, much smaller sizes.
You can also carefuly cut the leaves with sharp scissors
and the red colouration, returns to the end of the leaf.
Root system is as hairy as an azalea,
Good Luck growing a few.
