Devon,
United Kingdom 
After buying a Pieris on the market, I realised that I don't have any ericacious compost. I intend to plant it in the ground and wonder if it will be any good to mix some composted Lawsons Cypruss needles into the soil.

Same here - its more or less neutral here and all the acid lovers grow very well.

I don't know what type of soil it is. Perhaps I should just try it?

Or check the local area - if you see camellia, rhododendrons, azaleas and particularly blue hydrangeas (which means acid soil) growing well, Pieris will be fine.

Thankyou Bulba and Bamboo.There's a camellia next door which has been in for years so I guess it might work.

Is your soil alkaline, MBD? Our soil is neutral and we grow Pieris and Rhododendrons in it without ericaceous compost with no problems at all.
