How to grow

Cultivation

Grow in terrestrial bromeliad compost in full light, low to moderately humidity and no draughts. Water freely when growing and flowering, reduce slightly and add a balanced liquid feed weekly when in fruit, keep barely moist at other times

Propagation

Root basal offsets in early summer, or sever the leafy rosette at the top of the fruit, allow it a day or two to callus then root it in a barely-moist mix of peat, or peat substitute, and sand in indirect light at 21°C
