The soil should be acidic (pH 4.5-6.0), well-drained, and rich in organic matter. Dig a hole twice as wide as the root ball, ensuring the top of the root ball is level with the surrounding ground.
Gently loosen the roots before backfilling with an amended soil mix, such as a blend of peat moss, composted bark, and garden soil. Water thoroughly after planting.
Watering, Fertilizing, and Pruning Rhododendron President Lincoln
Consistent moisture is crucial, especially during dry periods. Water deeply and regularly, allowing the soil to dry slightly between waterings. Avoid overwatering, which can lead to root rot. Fertilizing supports healthy growth and abundant blooms. Apply an acid-loving plant fertilizer specifically formulated for rhododendrons in early spring, before new growth begins, and again in early summer.
Follow package directions carefully. Pruning is generally minimal, focusing on removing dead, damaged, or crossing branches. This is best done immediately after flowering.
- Watering:Deep, infrequent watering is preferred to shallow, frequent watering. Aim for consistent moisture, avoiding both soggy and bone-dry conditions.
- Fertilizing:Use an acid-loving fertilizer, applying in early spring and early summer. Avoid high-nitrogen fertilizers, which can hinder flowering.
- Pruning:Remove dead, damaged, or crossing branches immediately after flowering. Avoid heavy pruning, which can damage the plant.

Landscape Applications of Rhododendron President Lincoln
Rhododendron President Lincoln’s adaptability allows for creative integration into diverse garden settings. Below are three distinct landscape scenarios demonstrating its potential.
Scenario 1: A Formal Garden Setting. Three mature Rhododendron President Lincoln specimens are planted symmetrically along a paved walkway leading to a formal garden fountain. Their deep crimson flowers provide a bold contrast to the structured lines of the walkway and the lighter colors of surrounding boxwood hedges. The consistent spacing emphasizes the formality of the design. To complement the deep crimson, underplanting with silvery-leaved plants, such as Artemisia, adds textural contrast and softens the overall effect.
Scenario 2: A Woodland Garden. Rhododendron President Lincoln is ideally suited for a naturalistic woodland setting. A grouping of five to seven plants, varying slightly in size and maturity, are planted informally amongst existing shade-loving perennials, such as ferns (Dryopteris) and hostas. The irregular placement mimics the natural distribution of plants in a woodland environment. The rich crimson flowers stand out against the lush green backdrop, creating a vibrant focal point. The dappled shade provides the ideal growing conditions for this rhododendron.
Scenario 3: A Foundation Planting. Two Rhododendron President Lincoln plants flank the entrance to a house, creating a welcoming and dramatic visual impact. Their dark foliage provides a striking contrast to the lighter colored house siding. The plants are positioned to avoid obstructing windows or walkways. Companion plants such as variegated Japanese forest grass (Hakonechloa macra) add visual interest and texture at the base of the rhododendrons, softening the hard lines of the house foundation.
Suitable Locations for Rhododendron President Lincoln in Various Garden Styles
Rhododendron President Lincoln thrives in locations that offer partial shade and well-drained, acidic soil. Its versatility allows for successful integration into various garden styles.

Rhododendron President Lincoln
Rhododendron ‘President Lincoln’ is a highly prized cultivar known for its exceptional deep crimson blooms and robust growth habit. Its popularity has led to significant interest in its propagation and its role in ongoing rhododendron breeding programs. Understanding these aspects is crucial for ensuring the continued availability and improvement of this remarkable plant.
Propagation Methods for Rhododendron President Lincoln
Successful propagation of ‘President Lincoln’ relies on techniques that ensure the preservation of its desirable traits. Two primary methods are commonly employed: semi-hardwood cuttings and layering. Semi-hardwood cuttings, taken from new growth that has begun to harden, offer a relatively efficient method for mass propagation.
These cuttings are typically treated with rooting hormones to stimulate root development and planted in a well-draining propagation mix. Layering, a more traditional method, involves bending a low-growing stem to the ground, burying a portion of it, and encouraging root formation before separating the rooted section from the parent plant.
This technique is less efficient for large-scale propagation but offers a high success rate.
Role of Rhododendron President Lincoln in Rhododendron Breeding Programs
‘President Lincoln’ serves as a valuable parent in rhododendron breeding programs due to its striking deep crimson color and its relatively vigorous growth. Breeders utilize its desirable traits to create new cultivars with improved characteristics, such as enhanced disease resistance, larger flower size, or different bloom times.
Cross-breeding ‘President Lincoln’ with other rhododendrons with complementary traits can result in offspring with a wider range of colors and forms. For example, crossing it with a yellow rhododendron could yield offspring with shades of orange or reddish-orange. Its genetic contribution enhances the diversity and quality within the rhododendron family.
