How to slow down plant blooming

[Chris in Hamilton]

Cool temperature. Dim light. Somewhat higher humidity but maintain good air movement. Make the plant think it is a cold (within normal tolerances for the species) cloudy week. Not sure how effective this will be with Den. lindleyi specifically, but almost all plants' metabolic rate is completely dependent on ambient temperature, so everything slows down when it is cool. There's a reason that florists refrigerate most flowers.

Thanks Kirk! That is what I thought but I was worried the buds would drop. I'l blame you if they do
