Mulberry treesMulberries are large trees with ornamental appeal. They produce abundant small fruits rather like blackberries.
More about Mulberry trees
Mulberries are large ornamental trees, related to figs. There are several species, Morus nigra, also known as the Black Mulberry is the main fruting species, and also the best suited to the UK climate. Morus alba, the White Mulberry, also produces edible fruits but is primarily grown for its ornamental value. White Mulberries are also used in silk production - silkworms feed on their leaves, which have a much finer texture than the leaves of the Black Mulberry. Morus rubra, the Red Mulberry, is native to North America.
All the varieties we sell in this category are Black Mulberries, i.e. the fruiting form, and are grown on their own roots (not grafted).
Mulberries are best-suited to large open gardens or parkland areas, and they grow slowly into large trees of about 6m-10m height and spread. If planting several trees, allow about 10m / 30ft between trees.
The fruit resembles raspberries or unripe blackberries, and has a tangy sweet-sharp taste. It can be eaten fresh or used for cooking (in other words, just like raspberries and blackberries). The fruit is borne throughout the canopy of the tree, generally out of reach from the ground - the usual method of picking is by shaking the branches when the fruit is ripe in late August.
Mulberries are easy to grow (if you have the space), usually unaffected by diseases, and self-fertile.
Mulberries are slow-growing and can be grown in large pots or planters for a decade or more, although trees grown this way may eventually need to be planted in open ground.
There is a long tradition of growing mulberry trees in the UK, especially in the London area. In the early 17th century King James 1st actively encouraged the planting of mulberry trees in London in an effort to start an English silk industry. There is some debate as to whether King James and his advisors knew that sikworms preferred to eat the leaves of the White Mulberry species, but either through ignorance or because they found that White Mulberries were not suited to the English climate (which was much colder then than it is now) the vast majority of mulberry trees planted at this time were the Black Mulberry species. Silk production never took off in London, but left a legacy of Black Mulberry trees throughout the capital, and since these are long-lived trees many stil survive.
