Overview
Salix gooddingii Ball var. vallicola (Dudley) Ball is commonly known as Gooding's willow or Arizona black willow. It is a deciduous tree that belongs to the family Salicaceae. This tree is primarily found in Mexico and the southwestern parts of the United States, including Arizona, California, New Mexico, and Texas.
Description
The Gooding's willow tree is dioecious, meaning that there are separate male and female trees. The male trees produce catkins during early spring, while the female trees form small clusters of flowers. The tree has dark-green colored leaves that are elongated and narrow, which typically grow up to 6 inches long and 1 inch wide. The leaves are smooth, pointed, and slightly curved at their tips, and they have finely serrated edges. The bark of the tree is grayish-brown and relatively smooth, with shallow grooves and fissures.
Uses
Gooding's willow has several uses. The tree is often used for erosion control and as a natural barrier to mitigate flood damage along streams and riverbanks. It is known for its fast-growing nature and is therefore often planted for shade and windbreaks. The wood from this tree is also used in construction, furniture-making, and as firewood. The tree offers habitat and food for wildlife, including birds, rodents, and other small animals.
General Appearance
The Gooding's willow is a medium-sized deciduous tree that can grow up to 50 feet tall; however, it is usually much smaller in cultivation. The tree has a dense and rounded crown with branches that grow at an upward angle. The twigs of the tree are thin and flexible, with olive-green color. The tree's root system is extensive, allowing it to soak up moisture and nutrients from the soil, making it ideal for stabilizing soil around areas prone to erosion.

Humidity: Although humidity is not a critical factor in the growth of Salix gooddingii Ball var. vallicola, it is recommended to keep the humidity levels between 40 to 60% to ensure optimal growth.
Fertilizer: During the growing season, give Salix gooddingii Ball var. vallicola a slow-release, balanced fertilizer. Apply the fertilizer once a month, following the instructions on the package.
Propagation: The easiest way to propagate this plant is through softwood cuttings taken in the spring or the autumn. Plant the cuttings in a well-draining, soilless medium, and place them in a shaded and humid location until they root.
Cultivation
The Salix gooddingii Ball var. vallicola (Dudley) Ball, also known as the Goodding's willow, is a hardy plant that can grow in various climatic conditions. It is commonly found in wetlands, but it can also thrive in upland areas with well-draining soil. When cultivating this plant, it is important to keep in mind that it requires a lot of space as it can grow up to 30 feet tall and spread up to 20 feet wide.
Watering Needs
The Goodding's willow is a water-loving plant that requires constant moisture. It is important to keep the soil consistently moist but not waterlogged. Lack of water can cause leaf drop, while excessive watering can lead to root rot. During hot and dry spells, it is advisable to water the plant deeply once a week to ensure its survival.
Fertilization
Goodding's willow is not a heavy feeder, and excessive fertilization can do more harm than good. Fertilizing once a year in the early spring with a slow-release fertilizer will provide sufficient nutrients for growth. The fertilizer should be applied around the base of the plant, ensuring it is not in direct contact with the stem as it can burn the plant.
Pruning
Pruning is not necessary for the Goodding's willow, but if desired, it can be done during the dormant season (late fall to early spring). Pruning promotes the growth of new branches and canopy development, which can enhance the plant's aesthetic appeal. It is advisable to remove only a small portion of the plant per year, and to avoid cutting too close to the main stem as it can cause permanent damage to the plant.
Propagation of Salix gooddingii Ball var. vallicola
Salix gooddingii Ball var. vallicola (Dudley) Ball, or more commonly known as Goodding's willow, is a shrub or tree species that is native to North America. It belongs to the Salicaceae family and is characterized by its narrow leaves and long, thin branches. Goodding's willow plays an important ecological role in riparian habitats, as it helps stabilize soil and prevent erosion.
If you are interested in propagating Goodding's willow, there are several methods you can use. Here are some of the most common:
Propagation by Cuttings
One of the easiest ways to propagate Goodding's willow is through cuttings. You can take cuttings from the young twigs or branches in early spring, before the leaves begin to appear. Use a clean, sharp knife or pruning shears to cut a section of the wood that is approximately 6 inches long. Remove all the leaves except for the top two or three pairs. Dip the cut end in rooting hormone, and then plant the cutting in a pot filled with moist potting soil. Keep the soil moist and the cutting in a warm, bright area until root growth appears, which can take several weeks.
Propagation by Division
If you have an established Goodding's willow plant that has multiple stems or clumps of growth, you can propagate it by division. Wait until early spring to dig up the entire plant, and then use a sharp, clean tool to separate the different stems or clumps into individual plants. Be sure to keep each new plant's roots moist and shaded until you are ready to transplant it to its new location.
Propagation by Seed
Propagation by seed is also possible, but it is considered more challenging than the other methods. Goodding's willow produces tiny seeds that need to be stratified (exposed to cold temperatures) before they will germinate. Collect seeds in the fall and place them in a sealed plastic bag with a damp paper towel. Leave the bag in your fridge for 60-90 days, checking them every few weeks to make sure they stay moist. After this, plant the seeds in moist potting soil and keep them in a warm, bright area until they germinate.
Disease Management
As with many plants, Salix gooddingii Ball var. vallicola is susceptible to a variety of diseases that can cause significant damage if not managed properly. One of the most common diseases that affect this plant is leaf spot. This fungal disease causes small, dark spots to appear on the leaves of the plant, which can eventually lead to defoliation. To manage this disease, it is important to remove infected leaves as soon as they are observed. Additionally, fungicides can be used to control the spread of the disease.
Another disease that can affect Salix gooddingii Ball var. vallicola is powdery mildew. This disease causes a white, powdery film to appear on the leaves and stems of the plant. Infected leaves can become distorted and eventually drop from the plant. To manage powdery mildew, it is important to water the plant properly and avoid over-fertilization. Additionally, fungicides can be used to control the disease.
Pest Management
Salix gooddingii Ball var. vallicola is also susceptible to a variety of pests, including aphids and scale insects. Aphids are small, soft-bodied insects that can be found on the undersides of leaves. They feed on the sap of the plant and can cause significant damage if left untreated. To manage aphids, it is important to remove infected leaves and use insecticidal soap to control the population of the insects.
Scale insects are another common pest that can affect Salix gooddingii Ball var. vallicola. These insects attach themselves to the stems and leaves of the plant and feed on the sap. They can cause significant damage if left untreated. To manage scale insects, it is important to remove infected leaves and use systemic insecticides to control the population of the insects.
By staying vigilant and practicing good plant care, it is possible to manage the common diseases and pests that affect Salix gooddingii Ball var. vallicola. Regular monitoring and treatment can help keep this plant healthy and thriving.
