Propagation
Sow seed when ripe in a prepared bed or stratify seeds in a moist sandy soil, then place in a shaded position. Seedlings should be transplanted the following year.
Take soft tip cuttings of non-flowering shoots during summer.
General pruning information
These trees require little pruning. Remove dead or damaged branches during summer and pruning during winter should be avoided as it can encourage silverleaf disease. Spring pruning may give rise to sap bleeding.
Botanic information
Leaf: The leaves are ovate to rhomboidal and are pale green when young becoming mid to dark green, then turns yellow during autumn before falling. The leaf has a doubly serrated margin with an acute apex and a short petiole.
Flower: The slender pendulous male catkins appear during autumn and open in spring with the new leaves. The upright female catkins are downy and are up to 37mm (1½in) long on a short stem and disintegrate when producing seed in early summer.
Fruit: The catkin scales are deciduous from the main axil when releasing the winged nutlet. The seed is released during the driest period in endemic areas when riverbanks are low, allowing the seed to germinate. The seeds are viable but the plant may be reproduced vegetatively.
Note
Care should be taken when selecting a sight as the tree has vigorous roots that can lift concrete and block drains.
