Planting blueberries in limey soil

Thanks for your very prompt reply. …You say to plant in polythene lined trench 30cm deep. What diameter of hole if i am digging separate holes for my three plants…I have three holes dug already over 20inches diameter and well over 30 cm deep…. .Would Tippland Irish Mosspeat do on its own or would i need to add fertiliser. Someone told me that there is lime added to mosspeat that s sold in 200 litre bags? Thanks again for the advice so far!
