American Black Currant
Ribes americanum
Zones 3–5
Growing
Establishing American black currant is a long-term commitment to your landscape, as these woody shrubs typically require three years of growth before they begin producing fruit. Because they do not spread via suckering, you can plant them in structured rows or as part of a larger windbreak without worrying about them invading nearby garden beds. When planting, focus on keeping the area around the base of the shrubs clear of aggressive weeds and grasses. Using shallow cultivation around the base of the plants is the most effective way to manage competition without damaging the established root systems.
Maintaining healthy foliage is key to a productive harvest. While this species is generally hardy against pests, you should ensure your planting site allows for plenty of air circulation. Good airflow is your best defense against the development of leaf spot and other fungal diseases that can take hold in stagnant, humid conditions. If you are using these shrubs as part of a multi-row windbreak, placing them in the outer rows can help protect more delicate garden plants from harsh winds.
