Overall, Ribes viscosissimum Pursh var. hallii is a unique and valuable component of the North American ecosystem, providing sustenance and habitats for various animal species.Light Requirements
Ribes viscosissimum Pursh var. hallii (Jancz.) Jancz., commonly referred to as sticky currant, grows best in partial shade or filtered sunlight. Direct sunlight can be too harsh for the plant and can cause leaf scorching and drying. The ideal location for planting is under the shade of larger trees or shrubs, where it can receive dappled sunlight.
Temperature Requirements
The sticky currant is a hardy plant and can grow in a wide range of temperatures. However, it prefers cooler temperatures and can survive in temperatures ranging from -40°F (-40°C) to about 80°F (27°C). In warmer climates, the plant may require additional watering to keep the soil moist. In colder climates, the plant may go dormant during the winter months and regrow when the weather warms up.
Soil Requirements
The sticky currant prefers well-draining soils that are rich in organic matter. It can grow in a wide range of soil types, including loamy, sandy, and clay soils. However, the soil must be free of standing water as the plant can be susceptible to root rot. Ideal soil pH ranges from slightly acidic to slightly alkaline, with a pH between 6.0 and 7.0 being the best. Applying a layer of mulch around the plant can help to retain moisture in the soil and protect the roots from extreme temperatures.

Propagation of Ribes viscosissimum Pursh var. hallii (Jancz.) Janc.
Ribes viscosissimum Pursh var. hallii (Jancz.) Janc., commonly known as sticky currant, is a deciduous shrub native to western North America, from Alaska to California. The plant is popular among gardeners due to its showy flowers and edible berries. Here are some methods for propagating Ribes viscosissimum Pursh var. hallii:
Seed propagation
Seed propagation is a common method of propagating Ribes viscosissimum Pursh var. hallii. The seeds can be harvested from ripe berries in the fall. After cleaning the seeds, they must be stored in a cool and dry place until the following spring. In early spring, the seeds are placed in containers with moist soil and covered with plastic to maintain high humidity. The containers are kept in a warm and bright place until the seeds germinate. Once the plants have developed a few leaves, they can be transplanted to their permanent location.
Softwood cuttings
Softwood cuttings can also be used to propagate Ribes viscosissimum Pursh var. hallii. The best time to take cuttings is in early summer, when the plant is actively growing. Cuttings are taken from the tips of the branches, and the lower leaves are removed. The cuttings are then dipped in rooting hormone and placed in containers filled with a well-draining soil mix. The containers are covered with plastic to maintain high humidity and placed in a bright, but not direct, light. Watering is done as needed to keep the soil moist. After a month, the cuttings should begin to root. Once they have developed roots, they can be transplanted to their permanent location.
Hardwood cuttings
Hardwood cuttings can also be used to propagate Ribes viscosissimum Pursh var. hallii. Cuttings are taken from the dormant plant material in the winter, when the plant has gone into dormancy. The cuttings should be made from the previous year's growth and should be about 6-8 inches long. They are then dipped in rooting hormone and placed in containers filled with a well-draining soil mix. The containers are covered with plastic to maintain high humidity and placed in a bright, but not direct, light. Watering is done as needed to keep the soil moist. After a few months, the cuttings should begin to root. Once they have developed roots, they can be transplanted to their permanent location.
Disease Management
Ribes viscosissimum Pursh var. hallii (Jancz.) Jancz. is susceptible to several diseases. Some common diseases that might affect the plant are:
- Powdery mildew: This typically appears as a white or grayish powder on the leaves and stems of plants. To manage powdery mildew, it is recommended to remove and dispose of any infected plant material. Additionally, maintaining good air circulation and avoiding overhead watering can help prevent its spread.
- Leaf spot: This disease appears as dark, water-soaked spots on the leaves. To manage leaf spot, it is recommended to remove and dispose of any infected foliage. Maintaining proper soil moisture and reducing humidity can help prevent the disease from spreading.
- Anthracnose: This disease typically causes small, sunken spots on the leaves, stems, and fruit. To manage anthracnose, it is recommended to remove and dispose of any infected plant material. Maintaining good air circulation and avoiding overhead watering can help prevent its spread.
Pest Management
Ribes viscosissimum Pursh var. hallii (Jancz.) Jancz. can also be affected by various pests. Some common pests that might affect the plant are:
- Aphids: These small, soft-bodied insects feed on the sap of plants and can cause stunted growth and distorted leaves. To manage aphids, it is recommended to spray the plant with a strong stream of water or neem oil.
- Spider mites: These pests are small and difficult to see, but they can cause damage by feeding on the plant's sap. To manage spider mites, it is recommended to spray the plant with a strong stream of water or insecticidal soap.
- Caterpillars: These pests feed on the leaves and can cause significant damage to the plant. To manage caterpillars, it is recommended to remove them by hand or use a suitable insecticide.
Regularly inspecting plants for signs of disease or pest damage and taking prompt action can help prevent these issues from spreading and causing significant damage to the plant.
