This is a photo of the soil after watering ( Today ). I fertilize with Tamahi in the spring and BioGold in the fall. I haven't pruned branches since 2020; it's still weak.
I transplanted them just to check the roots, they are healthy, three times ( 2020 Akadama, pumice; 2022 pumice and 2025 akadama, kiryuzuna, kanuma and spagnum moss) I haven't pruned roots.
