I have decided to use hawthorn for my edge, but how should I plant it, what
distance apart? how deep, how do I prepare the soil?, I am also thinking of
planting it double, is this a go idea (2 rows)

Assuming that you are going to use established young pot grown saplings,
plant them at the same depth as they have been raised - in fact leave
the root ball and soil intact a.f.a.p. The soil should be well
cultivated with some slow release nutrients added at about
15-18ins/30-45cm deep. Make sure that the bed is high enough to allow
for subsequent settlement - remember that it is likely to be a long time
before it can be worked again. A double row is a good plan if you want
to increase the thickness of the hedge. Set the plants at 12ins/30cm.
apart in alternate rows 12-15ins/30-45cm. apart, or less if you want a
really dense hedge. Firm them in and water well.

Common Hawthorn or May [Crataegus oxyacantha] are hardy deciduous shrubs
fit to stand any UK winter, but it would be well to wait until after
your last frost before planting.
