It is mid-August in Brisbane and no sign of flower buds on my Kings - I have three. I put this down in part to my plants being too shaded. In past years I have had buds appear, only to dry up and fail. So my conclusion is that good light - direct sunlight - is the answer. I need to re-locate them I think. One on the side of a foxtail palm seems to be getting what it needs - on the eastern side of the palm, sheltered from the west. But not really likely to be a 'natural' location - it is tied on above a staghorn.
As for the Dendrobium
beetle - I have developed a technique that sees me cupping my hand below the foraging pest and then tapping the leaf so that the beetle falls into my hand....it seems their defence mechanism is, when disturbed, to drop before taking flight. Once caught, I simply crush them with a finger nail - they are tough little blighters.
I wonder if Success would eventually deal with them as sucking insects - thoughts?
