Ericaceous SOIL based compost NB.
Many ...maybe most...staff at the GC do not actually know the difference between lightweight ericaceous mpc and the genuine heavyweight soil. I guess it can be confusing. For permanent planting in containers avoid all the mpc rubbish...it is fine for temporary potting on, seed growing and cuttings. Inadequate otherwise and the cause of so many plants drying out or suffering from nutrient deficiency. Pointless, for example, for blueberries, rhodos, azaleas and the like in comtainers
Acers will be ok in ordinary john innes but they are just that much happier with acid soil. Might as well start off right
