A friend of mine has a few scores of Strawberry plants which for two seasons have neither borne flowers nor fruit. They had a strong healthy foliage, and produced the ordinary quantity of runners; and were not isolated, but grew amongst others that were productive and are three seasons old. The sorts are Black Prince, usually very productive, and a seedling from British Queen. Could any of your readers give a probable reason for this barrenness]

[No particular cause can be assigned for the barrenness of Strawberry plants; they have a tendency to come barren - a fact patent to every gardener. Sometimes the barren plants are self-sown seedlings which come up about the beds. The barren plants should be pulled up as soon as they show they will not produce bloom, and replaced by other plants; on no account take runners from the barren plants. At the Royal Horticultural Society's Gardens at Chiswick, from some cause not explained, two types of Strawberry plants, that have been well denominated " rogues," frequently put in appearance; - one is a most robust growing form that produces plenty of large leaves but no blossoms; the other gives small fruits full of seeds, and quite worthless. - Eds].
