I have just bought some new plants for my shady garden, including a new Acer (I killed the last!), Azalea, Skimmia and something else. Everything is in pots as it is a concrete yard and I planted them into containers using normal soil (not new compost) which I planned to enrich with good feed. I also bought some new bog-standard compost but I was too impatient to wait for it to arrive before potting them!
I have now realised that these are all Ericaceous plants. I have bought ericaceous liquid feed - will that be sufficient to 'sort out' the standard soil I have used, or will I need to buy new ericaceous compost and disturb them again?
