General characteristics of a Laburnum

Laburnum is a weeping tree that develops beautiful yellow pendulous flowers in June. Lanurnum in bloom is a very striking appearance with beautiful golden yellow flower clusters and one of the few weeping trees with flowers. The great advantage of this tree is that it is suitable for any garden: large or small. In addition, the tree grows on almost any soil. This small-growing tree requires little maintenance and is completely hardy. Toxic to animals and humans.

How to plant a Laburnum

Dig a planting hole 1.5x as wide as the root system; make sure the roots are covered with soil; do not plant deeper than to where the trunk begins

Caring for and pruning your Laburnum

Laburnum in the open ground usually suffices with natural precipitation. During the dry summer months, additional watering may be necessary.

A laburnum is preferably pruned as little as possible. This is because the tree does not tolerate pruning well as pruning wounds often do not heal properly and begin to rot. Since the tree has a naturally beautiful growth form, it is often not even necessary to prune. Should it still be necessary, for example after an infestation with a fungal disease, we recommend that you treat the pruning wounds afterwards with a wound sealant. This will prevent pathogens from entering the plant. Never prune in the fall and winter to avoid infections. The best time to prune a laburnum is immediately after flowering.

If you want to prevent your laburnum from self-seeding using the seeds, you can cut off the pods at the base. This way, you ensure that the plant puts its energy into forming new flowers.

It is also important to fertilize the plant regularly with a fertilizer specially formulated for flowering plants. This will help to promote flowering and ensure that the plant gets enough nutrients.


 

Where does a Laburnum grow

You can plant the laburnum weeping tree in any soil type, but it prefers light clay, silt and sand. The laburnum does very well in a sunny spot, but the tree does not like very strong winds. The golden rain also does not like prolonged wet soil - so it is important to choose a site with permeable soil.

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 leaves of laburnum are long-stemmed, elliptical and trifoliate. The underside is light to gray-green and finely hairy. It blooms with yellow butterfly flowers in 10-20 cm long, pendulous clusters. The fruits are 4-8 cm long pods, silky hairy at first, later dull brown. The bark is smooth and greenish brown.

Laburnum is deciduous and hardy.
