My Japanese Aralia plant gets full sun 10 – 3pm Zone 9 Kelseyville, Ca. It has been planted in the ground for 15 years. It never looked really full but did flower. Now in the past year the leaves are turning black around the edges and dying off. Today I cut it back. I wonder if I should dig it up and transplant it into a big container to baby it back to health? It is planted in volcanic soil. Help….I don’t want it to die it was my dad’s.
The full sun is likely just too much for this plant.
Though a Japanese Aralia needs the warm temps you should plant in a full or partial shade location.
