Almost all types of willow are dioecious, with the exception of the weeping willow. A willow (Salix) has either only female flowers or only male flowers. They are pollinated by bees.

frequently asked Questions

Are pastures poisonous for humans and animals?

No. All parts of the pasture are non-toxic. Young leaves are even edible. They can be used in salads. The rind tastes a bit bitter, but can be used to brew tea. The ingredients contained in the willow, such as salicin, are basic substances in the manufacture of medicines.

How should willows in the garden be cared for?

In principle, they are relatively easy to care for. Young plants need to be watered regularly. Even with older specimens, the soil should not dry out completely. Alternatively, a layer of mulch can be applied to the root disc. This limits the evaporation of water. Compost should be added in spring, alternatively long-term fertilizer.

Is it absolutely necessary to prune willow trees regularly?

Yes absolutely. Regular pruning should be carried out, as willows are usually fast-growing. Pruning measures should be made in spring. The plants are quite easy on pruning, they don't mind a radical pruning either.
