Traditional uses and benefits of Weeping willow

Plant Description

Weeping willow is a medium to large-sized, rounded, deciduous landscape tree with a stout trunk topped by a graceful broad-rounded crown of branches that sweep downward to the ground. The tree normally grows around 10 – 12 meters tall, occasionally reaching 18 meters. The short bole can be quite thick. It grows rapidly, but has a short lifespan, between 40 and 75 years. The plant is found growing in shrub land, riparian habitats, and fresh water wetlands, beside lakes, ponds, rivers, streams, in parks, maintained gardens and larger domestic gardens. The plant is tolerant of many soil types, including alkaline, loamy, sandy, and clay soils. However, their preference is for moist, well-draining, slightly acidic soils. If your soil is too alkaline, you can make it more acidic by amending it with sulfur. It rarely thrives on chalk.

Many consider this tree to have the best form of the weeping willows available in commerce. Bark is gray-brown or gray-black with irregular furrows. Branchlets are typically green or brown. This weeping willow can be a spectacular specimen at the edge of a pond with its branches gracefully weeping down to touch the water; however, it is often very difficult to site this tree in a residential landscape. Some experts believe that the true species no longer exists in the wild in China and that plants being sold today under the name S. babylonica are primarily hybrids or mistakenly identified similar species.

Stem

The stems are reddish to yellowish brown and smooth. The nodes are rounded, hairy, and point downward. The wood is weak and susceptible to breakage and litter.

Leaves

Weeping willow has yellowish-brown shoots, with small buds. Smooth, hairless leaves are alternate, simple, and linear-lanceolate with an acuminate apex. They are 9-16 cm long and 0.5-1.5 cm wide, acuminate, cuneate, and have finely serrated margins. The leaves are light green above, and grayish-green or glaucous beneath. In autumn, the leaves turn golden-yellow. They are glabrous, and the stipules are slender. The fall foliage is greenish-yellow or sometimes golden yellow. The leaf margin is finely toothed. Leaves are spirally arranged along the branches. Leaf stalk is 5-10 mm long and pubescent.

Flower

Plant is dioecious with Male and female flowers appearing in silvery green catkins born on separate male and female trees. Male catkin is 1.8-3 cm long and 0.5-1 cm wide while female catkin 1.5-2.5 cm long and 0.5 cm wide.  They are silvery-green, non-showy, and appear from April to May. The male catkin is the showiest with only stamens, no petals, and measures 1 to 2 inches long. Flowers richness in nectar attracts an abundance of insects.

Fruit

Fertile flowers are followed by dry, hard, 3-4 mm long capsule. It is initially green and turns yellowish-brown when ripened. Mature capsule releases many tiny, down-covered, or cottony seeds. It does not attract wildlife. They are not showy and create litter. They ripen in late May to early June.

History

Historically, weeping willow was used as a popular trading item along the Silk Road. It was introduced to England from Syria in 1730. It was first described and assigned its scientific name by the Swedish botanist and plant pathologist, Carl Linnaeus, in 1736. Linnaeus named weeping willow salix babylonica after mistaking it for the trees described growing along the rivers of Babylon in the Bible. The trees mentioned in the Bible were likely poplars, which are members of the willow family (Salicaceae). The species that Linnaeus observed was the variety that had been introduced into the Clifford Garden in Harte Kamp in the Netherlands.

Other Facts

• Weeping willow is a popular ornamental tree in northern China, and is also grown for wood production and shelterbelts there, being particularly important around the oases of the Gobi Desert, protecting agricultural land from desert winds.
• Stems are very flexible and are used in basket making.
• The plant is usually coppiced annually when grown for basket making, though it is possible to coppice it every two years if thick poles are required as uprights.
• The extensive root system makes this species useful for binding soils.
• Decoction or infusion of the bark has been used as a wash to make the hair grow.
• It is sometimes used for erosion control, because it has a well-developed root system.
• The plant is used in reforestation projects.
• The plant is traditionally grown in living fences in the northwestern Himalayas, where it helps to exclude livestock and other animals; mark out land boundaries; whilst also providing a range of medicinal and other uses.

Various Products

• Fodder: The leaves and tender shoots are used as fodder for cows and goats in some areas. The fodder compares favorably with lucerne. In a survey carried out in Bumthang district, Bhutan, in 1982, Salix babylonica was found to be among the preferred fodder trees by farmers.
• Apiculture: The flowers are a good source of honey.
• Fuel: Wood and branches of S. babylonica were traditionally used for fuel wood in China.
• Fiber: S. babylonica is a source of pulpwood and produces good quality newsprint paper also used for wrapping papers and high grade Kraft paper. Branches are used for basket making.
• Timber: Weeping willow wood is usually reddish-brown, light and soft, with a straight grain, and of moderate density. It is widely used for furniture, packing cases, agricultural tools, fiber board, plywood and mine poles
• Medicine: Leaves and bark have astringent and tonic properties. Catkins and young twigs are antipyretic. Leaf infusion is given to rheumatics.

Different Services

• Erosion control: Planting the tree along riverbanks prevents soil and water erosion, wave-shock and minimizes sediment deposition. In New Zealand, willows are widely grown for soil conservation purposes, where they are the most abundant exortic species after Pinus radiata.
• Shade or shelter: Weeping willow is an important tree species for farmland shelterbelts.
• Ornamental: S. babylonica is also valuable as an ornamental garden and park tree. The male is mainly the one planted for ornamental purposes.
• Pollution control: It tolerates high levels of sulfur dioxide.

Management Info

Commonly used management techniques include mechanical control (e.g. felling, excavating) and/or herbicides, e.g. glyphosphate, picloram, picloram/triclopyr. Herbicides can be applied by foliar spray, stem injection, and cut stump application. Repsrouting may occur.

The Willows National Management Guide: Current management and control options for Willow (Salix spp) in Australia is divided into six sections that includes detailed information on the spread and impacts of willows on riparian habitats, guidelines for how to plan a willow management program, including when to prioritize, detailed descriptions of available control and waste management methods, including when to use specific methods. The manual also includes important information on how to sustain the program in order to endure long term benefits, monitoring, managing erosion, re-vegetation and case studies of different methods, approaches and strategies in management.

The Weed Control Methods Handbook provides you with detailed information about the tools and techniques available for controlling invasive plants, or weeds, in natural areas. This Handbook is divided into eight chapters, covering a range of different control methods: manual, mechanical, promoting competition from native plants, grazing, bio-control, herbicides, prescribed fire, solarization, flooding, and other, more novel, techniques. Each control method has advantages and disadvantages in terms of its effects against the target weed(s), impacts to untargeted plants and animals, risks to human health and safety, and costs.
