Establishment
Planting units of winterberry are propagated by seed, rooted stem divisions, and stem cuttings alike. The germination is usually hindered by hard seed coats and embryo dormancy. Utilizing proper after ripening and cold moist stratification procedures, germination can be stimulated. Seed should be covered with at least 1/8 to 1/2 inch of soil on nursery beds. Fall seedings should be mulched for winter protection.
When seedlings are acquired, the sex of the plant is typically indeterminable, in contrast to those propagated vegetatively. In late fall root suckers can be directly dug and transplanted, while actively growing softwood cuttings are taken from late spring to mid-summer. The cuttings are first placed under glass or plastic, but once roots form and begin to grow, they can be transplanted into containers or nursery beds for further development.
Utilize standard tree and shrub planting procedures to plant bare rooted transplants, containerized, or balled and burlapped stock.
