A T-cut is made in the rootstock and a smooth, sloping cut is made on the lower end of the scion. The scion is then inserted into the T and wrapped and sealed. Other types of grafts are also usually successful, although there may be incompatibility between white and black mulberries. Hardwood, softwood and root cuttings also are suitable methods for propagating mulberries. Softwood cuttings of white mulberries root easily when taken in midsummer and treated with rooting hormone.
Red mulberries are less easily rooted.
Black mulberries are also somewhat difficult to propagate since they tend to bleed a lot. Mulberries are generally free of pests and diseases, although cankers and dieback can occur. The disease carries on from one season to the next, so collecting and burning infected fruits help control it. The ripe fruit is very attractive to birds, but there is usually enough fruit left over for harvesting. The fruit of black mulberries ripen in summer to late summer.
