There are wattangaree that can settle for semi shade, and prostrate wattangaree that make glorious low-maintenance floor covers. An excessive amount of feeding can kill them, particularly with a phosphorous wealthy fertiliser – a particular no-no for many native crops – and over-pruning can imply few if any blooms subsequent yr for a lot of banksias, as they flower on outdated wooden. Simply reduce off useless flowers, and that is it. Species that develop from lignotubers, like Banksia robur, B. spinulosa and B. serrata, could also be pruned again to floor stage. If doubtful, verify the label – or simply do nothing, and allow them to bloom.
