PJ4, if planting in the garden make sure you don't have alkaline soil as even if you mix ericaceous compost into soil, it won't last long. If your soil is alkaline (eg chalky or if you live in a limestone area), grow them in large pots instead.
Otherwise, prepare the planting hole well - time and effort spent on that will repay itself manifold in the future. Dig a hole twice as wide and deep as the pots they came in, mix some well-rotted farmyard manure or homemade compost with the soil from the hole, add some ericaceous compost, grit and some blood, fish and bone fertiliser following the instructions on the pack. Plant them so the base of the trunk sits at precisely the same level in the ground as it did in the pot and in a position where they will not get a lot of wind or any early morning sun. Water them in well and once a week until the leaves fall in Autumn. They should then thrive without any further attention needed for many years.
