'Screwing' alcantarea imperialis for pups
Hi There, I've read on this forum and in some bromeliad society newsletters that it is possible to get a plant to produce pups by destroying the apical meristem with a screwdriver. Well about three years ago I bought a few immature plants labelled Alcantarea Imperialis Rubra from a garden centre. Currently the biggest are about 900mm high and wide and none of them has produced any offsets. These plants must have been mislabelled as they are pale green without a hint of rubra anywhere. I have quite a few red Alcantareas but I really would like a supply of green pups to replace these ones when they flower. So my question is this - should I "screw" one of my nice green Alacantarea Imperialis 'Rubra' in the hope it will throw some pups? As an aside I had an immature (150mm) real rubra get hit by frost this winter which killed the centre of the plant, it is now pupping like mad... but it is a much younger plant and from my experience the younger they are the more readily they pup.
