ABOUT

Frangula alnus 'Ron Williams', commonly known as Alder Buckthorn 'Fine Line', is an ornamental shrub characterized by its unique and attractive appearance. The plant is noted for its narrow, columnar growth habit, presenting a stylish and contemporary silhouette. The foliage of 'Fine Line' is particularly noteworthy; it consists of slender, green leaves that are finely textured and dense, contributing to a feathery, delicate visual effect. These leaves emerge as a light green in spring and mature to a darker shade as the seasons progress. In autumn, the leaves transform into a spectrum of yellow hues before they shed, creating a vibrant display. Additionally, the Alder Buckthorn 'Fine Line' produces small, inconspicuous flowers in late spring to early summer. These flowers are creamy white, adding a subtle contrast against the green foliage. Furthermore, the plant may bear fruit that appears initially as a red berry before turning to a dark, almost black color upon maturity. Although the fruit is not a significant ornamental feature, it can add interest and attract wildlife to the garden. The stems and branches of 'Fine Line' form a vertical pattern that is both eye-catching and elegant, which, combined with its fine foliage, makes it a popular choice among gardeners looking to add architectural interest to their landscape without consuming too much space.

Pruning
  • water dropWater

    The Alder Buckthorn should be watered deeply to ensure moisture reaches the roots, generally requiring about 1 to 1.5 gallons of water per week, depending on rainfall and soil conditions. Overhead watering is not recommended; instead, water at the base of the plant to minimize the risk of leaf diseases. During the first growing season, it's crucial to maintain consistent moisture to establish a strong root system, so water may be required two times per week. Reduce the frequency as the plant becomes established but provide extra water during dry spells. Avoid overwatering, as the Alder Buckthorn does not tolerate soggy soil.

  • sunLight

    The Alder Buckthorn prefers partial to full sun conditions. It grows best with at least four hours of direct sunlight each day, but it can also tolerate light shaded areas. The ideal spot for this plant would have morning sunlight and some afternoon shade, especially in areas with hot summers.

  • thermometerTemperature

    The Alder Buckthorn thrives in temperatures between 50°F and 80°F and can withstand winter temperatures down to -30°F. It is important to prevent prolonged exposure to temperatures above 90°F as it can stress the plant. The Alder Buckthorn is a hardy species and is suitable for growing in USDA hardiness zones 3 through 7.

  • scissorsPruning

    Pruning the Alder Buckthorn is primarily for shaping and removing any damaged or diseased branches. It's best to prune in late winter to early spring before new growth begins. Prune sparingly, as this plant typically maintains a good shape naturally, but remove any crossed or rubbing branches to promote healthy growth. Annual pruning will suffice unless additional shaping is required to maintain its form.

    Alder buckthorn 'Ron Williams' performs best in a soil mix that's well-draining with a mix of loam, sand, and a small amount of compost. The ideal soil pH for this plant ranges from slightly acidic to neutral, approximately between 5.5 to 7.5.

  • plantRepotting

    Alder buckthorn 'Ron Williams' generally does not need frequent repotting; it can be repotted every 2-3 years as it is relatively slow-growing. It is best to repot in the spring before new growth begins.

  • circleLife cycle

    The Alder Buckthorn 'Ron Williams' begins its life as a seed, which after dispersal typically germinates in spring under the right moisture and temperature conditions. The seedling stage follows, where the plant establishes its root system and begins to produce its first leaves. As the plant enters the vegetative stage, it produces more leaves and stems, growing steadily in height and width while maturing into a shrub. Flowering occurs in late spring to early summer, with small, inconspicuous flowers that are pollinated by insects, leading to the production of berries. The berries mature by late summer to autumn, turning red and eventually black when ripe, which are then eaten by birds and other animals, aiding in seed dispersal. Lastly, the plant enters a period of dormancy during the winter months, reducing its metabolic activity until the next growing season begins.

      Spring-Early Summer

    • The Frangula alnus 'Fine Line', commonly known as the Alder Buckthorn 'Fine Line', is most effectively propagated by softwood cuttings during late spring or early summer. For this approach, a gardener should select healthy, new growth that has not yet become woody. Cuttings should be about 4 to 6 inches (10 to 15 cm) long with several leaves left on the top. The bottom leaves are removed, and the cut end is dipped into rooting hormone powder to encourage root development. The treated cutting is then inserted into a well-draining soil mix, ensuring that at least one or two leaf nodes (where the leaves meet the stem) are buried in the soil. The soil should be kept moist but not waterlogged, and the cutting should be placed in a warm area with indirect light. Using a plastic cover can create a greenhouse effect, maintaining high humidity around the cutting to facilitate rooting. After several weeks to a few months, the cutting should develop roots and can then be transplanted into the garden or a larger pot for further growth.
