Medlars tolerate most soils, unless very chalky or badly drained, but grow best in a deep, fertile, well-drained soil. They will do best in a warm, sheltered site in sun but can be grown in partial shade. Leaves and flowers are easily damaged by strong winds.
Due to their spreading habit medlars are best grown as standard or half-standard trees (trees with a well developed clear trunk). Medlars are grafted onto quince or hawthorn rootstocks. The semi-vigorous Quince A and BA29 rootstocks offer greater stability, producing trees 4-6m (13-20ft) in height and spread. Trees are self-fertile, so there is no need to worry about pollination groups and only a single tree need be grown to produce fruit.
If planting a new tree, ideally do so between November and March, and if planting more than one, allow 4.5m (15ft) between each tree. Stake trees for the first three or four years.
In March apply a general fertiliser, such as growmore, at 70g per sq m (2oz per sq yd) over the rooting area. After applying fertiliser, mulch with well-rotted farmyard manure or compost.
Adequate moisture is essential to obtain strong growth and good cropping, and young tree in particular should be watered well during dry spells in spring and summer for the first three or four years.
