Grow in any well-drained soil, including, dry, chalky, or sandy soils, preferably in full sun or in light dappled shade. Junipers need little, if any, pruning.
To propagate- remove seed from flesh as soon as ripe and sow in containers in a cold frame; germination may take up to 5 years. Root ripe-wood cuttings in early autumn.

Other use
In medieval Europe a fire of juniper wood was burned to discourage evil sprits and protect from plague. It was thought that felling a tree would bring death in the family within a year. J. communis’ medicinal properties were recorded by ancient Greek and Roman physicians. Culpeper recommended it, among many other uses, as “a counter-poison, resister of the pestilence and excellent against the biting of venomous beasts”. It is famous as a flavouring ingredient in gin- the English word being an abbreviation of “Holland’s Geneva” as gin was first known, from the Dutch word for juniper, jenever. This is a traditional alcoholic drink of the Netherlands and Belgium, from which gin evolved. It became popular in the United Kingdom when William of Orange, leader of the Dutch Republic, occupied the English and Scottish thrones with his wife Mary.
