Dappled willow care: Add color to your landscape

Shrubs are versatile plants that add beauty to any garden and can grow well in tough spots where other plants might struggle. However, many shrubs, such as Rhododendrons, Azaleas, and Camellias, are difficult to grow because of their ideal growing condition and inability to adopt different pruning methods. Hence, gardeners can choose dappled willow as an easy-care plant because of its low maintenance, adaptability, and colorful pattern.

The dappled willow is a fast-growing shrub that produces leaves with white, pink, and light green colors, making it perfect as an ornamental plant. This shrub can be planted alone, in small groups, or as a hedge. However, it also produces yellow catkins in early spring and attractive foliage as small trees.

With its drooping branches, colorful leaves, and red stems, it is a great choice for gardeners to add beauty to any space. Growcycle provides multiple gardening tips and hacks to ensure the healthier growth of plants with the right pruning methods. 

Origin and History

Dappled willow was first grown in Japan for its pretty, colorful leaves and slightly drooping branches. In the late 1970s, a Dutch hosta breeder introduced it to the West, and it was reintroduced to the U.S. in the 1980s under its Japanese name. Later, in 1996, a new version called ‘Flamingo’ was created in the Netherlands.

It offered better features and became a favorite among gardeners. This shrub grows naturally in wet areas like marshes, streams, and seeps. It is native to Japan, Korea, China, and southeastern Siberia. 

Botany of Dappled Willow

The dappled willow is a tri-colored willow, scientifically known as Salix integra. It belongs to the Salicaceae family and is also popular by other names, such as Flamingo, Shrimp, Japanese Flamingo, Nishiki, and Flamingo-Dappled. 

• Size: When mature, it typically grows to 4–6 feet and spreads 5–7 feet wide. 
• Stems: It usually has younger pink stems that slowly turn red in winter, adding color to the plant. However, in warmer winters, all stems turn red during the cold weather. 
• Leaves: This Nishki willow shrub produces narrow, lance-shaped leaves up to 4 inches long. They are especially colorful in spring to early summer, with a mix of white, pink, and green, but they slowly become green as summer goes on.
• Flowers: In spring, this shrub produces small, non-showy yellow flowers that grow in tiny catkins less than 1 inch long. However, it is mainly grown for its colorful leaves. 
• Growth Habit: Usually, the dappled willow has a rounded or arching growth habit with a dense, bushy appearance. It grows multiple stems from the base, creating a full and vibrant look.

Benefits of Dappled Willow

The dappled willow is a unique multi-colored shrub that offers multiple benefits such as:

• Fast Growth: It is a fast-growing shrub that can grow up to 4 feet yearly and reach 8-10 feet in just a few years.
• Improved Air Quality: This dense shrub helps improve air quality by absorbing carbon dioxide, releasing oxygen, and trapping dust and pollutants, making a healthier environment. 
• Low Maintenance: This shrub grows well in different soils, sunlight, or shade. It only needs light water and pruning to keep its shape, making it perfect for busy gardeners.
• Helpful in Pollination: This willow shrub attracts pollinators such as bees, birds, butterflies, and insects because of its dense, vibrant foliage, improving the ecosystem. 
• Natural Privacy Screen: This shrub's thick, tall growth is a natural privacy screen. Planting it in rows or groups creates a leafy barrier that blocks views and reduces noise, creating a quiet environment. 
• Aesthetic Look: Its multi-colored foliage, weeping branches, vibrant leaves, and bright red stems make it a beautiful addition to ornamental plants and boost the beauty of gardens. 
• Windbreak: The strong structure of the dappled willow helps block strong winds, protecting more delicate plants from damage.

Quick Tips to Plant Dappled Willow

Planting a dappled willow (Hakuro Nishiki) is relatively easy. Here are some quick tips for planting and caring for this ornamental shrub:

• Dappled willows thrive in full sun to partial shade. The full sun boosts their vibrant leaf color.
• They prefer moist, well-draining soil but can tolerate various soil types, including clay or sandy soil.
• Loosen the soil where growers will plant the willow.
• Mix in compost or organic matter to improve drainage and nutrient content.
• Early spring or fall is ideal for planting.
• Make a hole twice as wide and as deep as the root ball.
• Place the shrub in the hole, ensuring the top of the root ball is level with the ground.
• Fill the hole with soil, tamp it down gently, and water thoroughly to eliminate air pockets.
• Keep the soil consistently moist, especially during the first year as the plant establishes its roots.
• Mulch around the base to retain soil moisture.
• Prune in late winter or early spring.

Types of Dappled Willow and Other Varieties

There are multiple dappled willow varieties that bring unique features and beauty, making them great choices for gardens:

Dappled Willow Care Guide

Dappled willow shrubs need specific conditions to thrive well. Hence, gardeners need to maintain these factors:

1. Light 

Dappled willow grows best in full sun, with at least six hours of direct sunlight each day. It thrives best in hardiness zones 4 to 9 and helps to produce bright leaves and strong blooms. It is better to avoid too much or too little sunlight to keep optimal growth. 

Although the shrub can handle partial shade, too little sunlight can reduce flowers and make the leaves less colorful. In hot areas, it prefers some afternoon shade. Hence, gardeners need to place it in a location with enough sunlight. 

2. Water 

Regular watering is important during the first growing season of dappled willow. Hence, it is better to water it about once every three weeks or more often. Once the plant is established, it needs less water, so adjust the water schedule and ensure that the soil dries out completely. 

If it is potted in a 5-inch pot and not exposed to direct sunlight, gardeners need to water it with 0.8 cups of water every 9 days. Mulch can keep the soil moist in dry areas, as too much dryness can reduce its growth. 

3. Soil 

The Japanese Willow shrub can grow best in moist, well-drained soil with a pH between 5.5 and 7.5. It thrives in moist soil but not in standing water. Hence, it is better to avoid clay that holds too much water. 

The soil that contains loamy and organic matter like compost is best for the healthier growth of shrubs. Therefore, gardeners can add sand or perlite for better drainage. 

4. Temperature and Humidity 

The shrub usually tolerates temperatures between -13°F and 100°F. In colder climates, it needs winter protection, such as mulch, while in hot areas, gardeners need to maintain regular watering and partial shade.

Although it prefers moderate humidity and temperatures between 41°F and 95°F (5°C to 35°C), gardeners need to use wind barriers or consistent watering to reduce any leaf damage, such as wilting leaves and leaf drops. 

5. Fertilizers

Dappled willows usually grow well without extra fertilizer, but feeding them once a year can keep them healthy. During their active growth period in early spring, gardeners can use a balanced 10-10-10 fertilizer to help maintain vibrant foliage.

The plant should be fed every 4-6 weeks during the growing season for better results. Gardeners should also water the plant before and after applying fertilizer to prevent root damage. Overfertilizing should be avoided, as it can harm the plant instead of helping it.

6. Pest and Disease Control

Dappled willows are resistant to some diseases but can still be affected by issues like aphids, rust, willow scab, powdery mildew, and leaf spots. Gardeners should check the plant regularly for signs of these problems and maintain consistent watering to keep it healthy.

If chemical treatments are needed, it is best to use systemic insecticides, well-formulated fungicides, or organic insect soaps to manage pests and diseases effectively.

Pruning Dappled Willow

Pruning dappled willow is essential for maintaining its shape, encouraging new growth, and improving its vibrant foliage. Here is how to do it:

Best Time to Prune

• Prune in late winter or early spring before new growth begins.
• Light trimming can also be done throughout the growing season to maintain the desired shape.

Tools to Use

• Use sharp, clean pruning shears to make precise cuts and prevent disease spread.

How to Prune Dappled Willow 

• Remove the tallest or older branches first. 
• Cut the branches close to the ground, leaving no leftover stumps.
• Remove 1 to 5 branches, or about a third of the total branches.
• Next, cut back any weak, dead, or diseased branches with bypass shears.
• Remove any branches that cross or split, starting from the top.
• Use lopping shears for branches thicker than 0.5 inches (1.3 cm).
• Trim off any shoots growing at the base of the plant 1 to 2 times a year.
• If the plant is too overgrown or unhealthy, cut it back to a couple of inches above the ground.
• After pruning, water and fertilize the plant properly.

Shaping Dappled Willow

• Cut the tops of branches to reduce height or shape the plant.
• Make cuts just above the side buds, leaving about 0.25 inches (0.64 cm) above the bud.
• Now, trim side branches at a 45-degree angle to the main trunk and about half the size of the main branch.
• For thick hedges, make small cuts at the top to allow light into the lower parts of the plant.
• For a certain height, cut some branches inside the plant to create space at the top.
• Now, shape the plant like an "A" by curving the top inward to allow more light to reach the bottom.
• Make sure the plant is balanced by trimming smoothly on all sides for a healthy and pretty look.

Propagating Dappled Willow

Propagating dappled willow allows gardeners to grow new plants from existing ones. Here is the complete guide to do it:

Propagate Dappled Willow through Stem Cutting

• Choose 6 to 8 inches long stems, ensuring they are not too thick or too small.
• Cut those stems at a 45-degree angle to maintain the absorption. 
• Place the cut stems in a pot filled with potting soil.
• Push the stems 2-3 inches into the soil. 
• Water the container well to keep the soil moist. 
• Avoid overwatering to prevent the new roots from drowning.

Propagate Dappled Willow through Softwood Cutting

• Select healthy, non-flowering stems that are 4-6 inches long.
• Use sharp pruning shears to make a clean cut just below a leaf node.
• Remove the lower leaves to expose the nodes needed for rooting.
• Dip the cut end in the rooting hormone. (Optional)

Propagate Dappled Willow through Soil 

• Create a hole in the soil using a pencil or finger to make space for the cutting.
• Insert the cutting into the hole, ensuring the nodes are buried.
• Push the soil around the cutting to remove air pockets and secure it in place.
• Water the soil thoroughly right after planting to keep a balanced shape.
