Willow Forrest

Do you want to plant a Willow Forrest? Here you will find all the information you need on how to best plant the Willow Forrest, and on pruning and caring for your Willow Forrest.

General characteristics of a Willow Forrest

The goat willow (Salix caprea) is a tree in the willow family (Salicaceae). It is also called the water willow. The species is common in Europe and Northeast Asia, and not exclusively in damp locations. The goat willow is one of the species native to the Netherlands. S. caprea is usually seen as a shrub, but it can also be cultivated as a tree. In the wild, S. caprea will eventually develop into a tree. 

The leaves are oval, dark green, and slightly hairy on the underside. The scattered leaves of the goat willow appear after flowering. Only the Eared Willow and the Grey Willow have leaves that are somewhat reminiscent of those of the goat willow. 

The goat willow is one of the first to flower after winter, making it an important food source for many early insects. The goat willow has catkins covered with long, hairy bracts. They flower in March and April. The goat willow is dioecious. Male catkins are ovoid and initially covered with silvery hairs. Then, densely packed yellow stamens appear. Female catkins are slender, pale green with short, whitish styles. The female catkins are longer than the male. Both male and female flowers have a single nectary.


How to plant a Willow Forrest

Usually supplied as self-rooting cuttings of 1-3 m in length. Plant as deeply as possible, 40-60 cm into the soil, preferably until the soil is moist, ideally from mid-February to late March. There is less chance of the slits taking root in November or December.

Caring for and pruning your Willow Forrest

Pruning

Pruning a willow is a crucial step in promoting its growth and maintaining its shape. Generally, the best time to prune a willow is during late winter to early spring, when the tree is dormant. This is usually between January and March, depending on the specific climate zone.

Pruning a willow during this period minimizes the risk of disease and infection because the tree is less susceptible to stressors. Furthermore, it is easier to identify branches that need to be removed because the tree is defoliated. If you notice your willow is becoming overgrown, showing signs of disease, or simply needs a new shape, now is the ideal time to take action.

Pollarding

Pollarding a willow is a traditional pruning method used to rejuvenate the tree and extend its lifespan. The best time to pollard a willow is in late autumn or early winter, usually between November and December. During this period, the tree has shed its leaves and is in a dormant state.

Pollarding a willow involves cutting the branches back to the trunk, creating a gnarled, characteristic shape. This process stimulates the growth of new shoots and creates a denser, healthier structure. It's important to remember that not all willows are suitable for pollarding, so it's advisable to consult a professional landscaper before undertaking this step.

Where does a Willow Forrest grow

In the Netherlands and Belgium, the species is common everywhere. It thrives in sunny to partially shaded, open places (pioneer) on moderately nutrient-rich, fairly dry to moderately moist, light soil (sand, loam, and loess). It grows primarily in forests, wooded areas, hedgerows, and cleared areas.

Its natural range extends throughout Europe, with the exception of the far north and the far south, and extends into northeast Asia. It is a pioneer plant on fallow land. S. caprea is more drought-tolerant than other native willow species. The species also tolerates more lime in the soil. Due to its susceptibility to rust, the species is less suitable as a tree in an urban environment. Its susceptibility to watermark disease is low. Therefore, although beautiful specimens can sometimes be found in nature, S. caprea proves unsuitable as a tree in an urban environment. However, as a native shrub, capable of growing into a tree if necessary, the species is indispensable.

Reproduction rate

1. Very low reproduction rate. The plant hardly spreads, has few seeds or vegetative spread (e.g., trees with heavy seeds).
2. Low reproduction rate. Spread via limited seed production or specific conditions required
3. Average reproduction rate. Regular spread, depending on wind, water, or animals, at a moderate speed (e.g., dandelion).
4. High reproduction rate. Many seeds and multiple spread strategies (wind, birds, vegetative). Quickly colonizes open spaces
5. Very high reproduction rate. Invasive species that spread explosively over large distances (e.g., Japanese knotweed).

Harvest/recognition in winter

The bud scales are yellow-brown to reddish, and also initially hairy but soon become bare. The buds with catkins are noticeably larger. The bark of young trees is smooth and gray with diamond-shaped lenticels. In older trees, vertical fissures develop that connect the lenticels. It has attractive yellow and green catkins between 3 and 7 centimeters long; it grows upwards; in winter, the tree is bare, and the weeping shape of the branches is clearly visible.
