The seed can generally be purchased of any seedsman. I bought mine at Landreth's. I soaked the seeds in water for forty-eight hours before planting. When treated thus they sprouted almost as freely as could be desired. Those not soaked came up sparsely and very badly.
The ground was prepared as for ordinary garden seeds. The seed was placed in rows, about one foot apart, and about one inch deep. I kept the plants carefully weeded from their first appearance till the autumn. The result has been that plants raised one spring are fit for setting out as hedges the next spring.
