Greetings from Japan,
I'm new to this forum and i'm seeking advice for trimming a recently potted Japanese Maple. I was gifted this beautiful specimen around the end of January 2022 from a local friend here in Japan. He was removing some landscape and noticed a shrub that had the maple growing inside the bush.
From the looks of it, the maple must be 5-6 years old. The root system when given to me had a few large roots and nothing more. I took the maple and potted it with a combination of Akadama Pride and sphagnum moss purchased for the local store. I watered it and kept the mixture moist and in semi-low light conditions for about 1 month. The growth on it has surpassed what I thought would appear and in such a short time. It is so beautiful and with the cutting back that occurred during the constant trimming of the shrub has given it such a unique trunk and natural jin.
My question is this, with all of the new growth that has taken place, should I cut back some of it to allow the roots to grow stronger or just let it continue to grow? It is in a plastic pot that has a 10" diameter and is 6" deep. It drains at a slow pace with a watering occurring around every 7-10 days. Will post pictures soon. Im currently away from the plant now. It receives 6-7 hours of full to semi-full sunlight daily.
