Propagation of Ribes Menziesii Pursh var. Leptosmum (Coville) Jepson
Ribes Menziesii Pursh var. Leptosmum (Coville) Jepson, commonly known as the pine-flowered currant, is a deciduous shrub native to western North America. The plant has a slow growth rate but can grow up to 10 ft tall and wide.
Propagation by Seeds
Propagation of Ribes Menziesii Pursh var. Leptosmum can be done by seed which can be collected in late summer when the berries ripen. Seeds should be cleaned and stratified in a mixture of sand and peat for 3 months to break down the hard external coat which will allow water to penetrate and improve germination. The seeds can then be sown in trays or pots under controlled environmental conditions, with bottom heat and high humidity. The seedlings can be transplanted once they are large enough to handle.
Propagation by Cuttings
The plant can also be propagated by hardwood cuttings taken in late autumn or winter when the plant is dormant. Select healthy branches and make cuttings 6-8 inches long, remove the leaves, and keep only 2-3 nodes. Dip the cuttings in rooting hormone and plant them in a mixture of sand and peat or perlite. The cuttings are then covered with a plastic bag to increase humidity and placed in an area with bright, filtered light, not direct sunlight. The cuttings will root and can be transferred to individual pots once the root system is established.
Propagation by Suckers
Ribes Menziesii Pursh var. Leptosmum can also be propagated by suckers. The plant naturally produces suckers, which are shoots growing from the plant's base. These suckers can be detached from the parent plant, and potted in a soil mixture made with equal parts of sand, peat, and perlite. The suckers should be kept moist and placed in a location with bright, indirect light.
Disease Management
There are a few common diseases that Ribes menziesii Pursh var. leptosmum (Coville) Jepson may be susceptible to, including powdery mildew and leaf spot. Powdery mildew is identifiable by the white, powdery substance that grows on the leaves, while leaf spot can cause brown or black spots on the foliage.
To manage powdery mildew, it is important to keep the plant well-aerated and to avoid overwatering. Fungicidal sprays can also be used to treat the disease. Leaf spot can be managed by removing infected leaves and branches, as well as improving the plant's air circulation.
Pest Management
There are a few pests that may be attracted to Ribes menziesii Pursh var. leptosmum (Coville) Jepson, including aphids and spider mites. These pests can cause damage to the plant's leaves and stems.
To manage aphids and spider mites, it is important to keep the plant well-maintained and to remove any infected leaves or branches. Insecticidal soaps and horticultural oils can also be used to control these pests.
Overall, proper maintenance of Ribes menziesii Pursh var. leptosmum (Coville) Jepson will help prevent the onset of disease and pest problems. Regular inspections and the removal of infected material can go a long way in keeping the plant healthy and thriving.
