Crepe Myrtle Cutting
r/bonsai
Cut the chunk at the widest point and score the bottom about a half inch around and apply rooting hormone.
Then put 3 screws in a triangle pattern into the base to use for wire tie downs.
I put them directly into a coarse mix of usually lava and pumice.
Most importantly, I put down a layer of shredded sphagnum around the base to retain moisture while rooting.
I usually put them under some shade cloth until they start budding out then transfer to full sun and start feeding them heavy.
