Fertilization of Sambucus pubens Michx. var. arborescens Torr. & Gray
Fertilization is essential for the health and growth of the elderberry plant. Below are the guidelines for fertilizing:
- Timing: Fertilize the elderberry plant during the plant's active growing season, which is typically from early spring to early fall.
- Type: Use a balanced fertilizer, such as a 10-10-10 blend, at half strength level.
- Application: Distribute the fertilizer evenly around the base of the plant, taking care not to pour it directly on the stem.
- Quantity: Apply about one pound of fertilizer per plant.
Pruning Sambucus pubens Michx. var. arborescens Torr. & Gray
Proper pruning ensures that the elderberry plant remains healthy and vibrant. Below are the guidelines for pruning:
- Timing: Prune the elderberry shrub in late winter or early spring before new growth occurs.
- Method: Use clean, sharp pruners to cut back any dead or damaged wood. Aim to remove about one-third of the plant's overall size.
- Epimediums: Remove the oldest, thickest stems from the base of the plant to encourage the growth of new, healthy stems. Cut off any weak or spindly shoots, leaving only the most robust stems to thrive.
Propagation of Sambucus pubens Michx. var. arborescens Torr. & Gray
The Sambucus pubens Michx. var. arborescens Torr. & Gray, commonly known as American red elderberry or elder, is a deciduous shrub that belongs to the family Adoxaceae. Propagation is the process of producing new plants from existing ones. Several methods are available for propagating elderberry, including:
Sowing Seeds
Seed propagation is an effective way of growing American red elderberries. The matured berries of the plant are collected and allowed to dry in a cool and dry place. The dry berries are then cracked to allow easy extraction of the seeds, which are soaked in water overnight. The seeds are sown in a propagating tray containing a mixture of peat moss and sand and covered with a plastic wrap to maintain moisture. The tray is kept in a warm place, and the seeds germinate in 2-3 weeks.
Cuttings
Cuttings are a fast and efficient way of propagating American red elderberries. The cuttings should be taken in late summer when the plant has just finished flowering. A 3-4inch hardwood stem is cut with a sharp knife, with a bud at the top. The leaves are removed, and the stem's bottom is dipped in rooting hormone powder and planted in a propagating tray containing a mixture of vermiculite and peat moss. The tray is kept in a warm and humid place, and the stem will start developing roots in 4-5 weeks.
Root Division
Root division is another propagation method that can be applied to American red elderberries. It is best done in early spring before the plant has started to grow new leaves. The soil around the plant is dug up and the roots are separated into smaller pieces, with a minimum of two growing points per section. The sections are then replanted in a new area and watered thoroughly.
In conclusion, propagating American red elderberries can be achieved through sowing seeds, cuttings, and root division. Each method has its advantages and requires adequate care and maintenance to ensure successful propagation.

To manage this disease, it is recommended to keep the soil under the plant clean and free of debris. Additionally, it is essential to water the plant roots, not the foliage, to prevent the disease from spreading.
Rust: Rust is a fungal disease that can affect the plant's leaves and stems, causing orange or brown spots. The disease can lead to defoliation and stunted growth. To manage this disease, it is recommended to prune the infected parts of the plant and apply a fungicide as directed by the manufacturer.
Common Pests Affecting Sambucus Pubens Michx. var. Arborescens Torr. & Gray
Japanese Beetle: Japanese beetles are common pests that can damage the leaves, flowers, and fruits of the American Elderberry plant. The insect feeds on the foliage, causing it to skeletonize and brown. To manage this pest, it is recommended to handpick and destroy the beetles. Additionally, using insecticidal soap and neem oil can prevent further infestation.
Aphids: Aphids are small insects that can cause various problems to the plant, including yellowing of leaves, stunted growth, and defoliation. To manage this pest, it is recommended to use natural predators like ladybugs or lacewings. Additionally, using insecticidal soap and neem oil can prevent further infestation.
Spider Mites: Spider mites are tiny pests that can cause damage to the plant by sucking its sap, causing yellowing of the leaves and stunted growth. To manage this pest, it is recommended to increase the plant's humidity by spraying it with water. Additionally, using insecticidal soap and neem oil can prevent further infestation.
