Propagation
Fresh seed should be sown in a well-drained media and the kept moist but not wet. Maintain a temperature of 18º to 21º C. (64º to 75º F) in an unheated glasshouse or open frame. Germination occurs within 3-weeks to 3-months depending on the species, then prick out and pot up. 

Careful not to over water seedlings, as they are prone to damping off and larger plants are difficult to transplant. When removing seed from Banksia fruits it may be necessary to place the fruit in an oven for 60 minutes at a temperature of 120° C. to simulating the effect of a bushfire to opening the valves.  

Note:
The seeds from the species will germinate in 21 to 42 days and there is no pre-treatment required.  When planting place the winge point up.

General pruning information
When pruning reduce only the new growth as cutting old wood is likely to cause dieback. Limbs may be removed back to the collar.

Cultivation
Generally, Banksia species prefer a well drained, sandy soil that is tending acidic but many species from Western Australia grow on acidic top soils with alkaline subsoil. When the growing Western Australian species outside their native habitat technique of building a garden bed, of acidic soil above a layer of agricultural lime commonly produces better results particularly in raised garden beds or on slopes. During establishment, keep the soil moist but not wet and do not use fertiliser that contains phosphorus.

Botanic information
Leaf: The leathery textured dull dark green oblong leaves have a cuneate base and a truncate apex and are up to 60 mm (2⅜ in) long by 20 mm (¾ in) wide. The margins are serrated and the leaves are densely rusty-tomentose when young becoming glabrous on the upper surface and the petiole is up to 5 mm (¼ in) long.

Flower: The reddish to yellow green tubulate flowers have glaborous perianth segments that are up to 34 mm (1¼ in) long and a pistil to 31 mm (1¼ in) long. They are arranged in an axillary or terminal cylindrical spike that is 100 mm to 270 mm (10½ in) tall by 88 mm (3½ in) wide and appear on short lateral branchlets from early to, late spring.

Fruit: The glabrous narrow elliptical embedded follicles are up to 20 mm (¾ in) long by 10 mm (⅜ in) high and wide. They are arranged in a villous spike that is persistent of the plant. The follicles open after fire and release obliquely obovate seeds with a body of to 12 mm (½ in) long by 8 mm (⅜ in) wide and have a notched wing up to 15 mm (⅔ in) wide.
