November last year we planted a grass tree, which is growing really well, thanks to advice from H1 re molasses, seasol & powerfeed. It has now put up it's flower spike (and don't they grow fast - 2 inches a day I reckon!) and I don't know whether to cut it off or not. It looks fantastic, but, my thoughts are: is it under stress? Will the energy used for this flower sap the plant ? and how far down should I cut it?
TIA.
