What sort of soil do Japanese Maples need?
Good news! Japanese Maples are not fussy about soil types. Key to success is good drainage - Acers hate standing in water for any extended period, and not potting into too large a plant pot - Acers don't thrive in pots which dwarf the plants.
It is a common myth that Acers need ericaceous soil - our plants are not grown in ericacous compost.
