Is it a must to fertilise my Tillandsias?
Tillandsias can grow without fertiliser but a regular fertilisation program will help the plant grow faster, larger, produce flowers and have more pups. Fertilise the plants once or twice a month with a very dilute (at 1/4 strength) liquid fertilizer, spray the plant or submerge it in the diluted fertiliser solution. The fertiliser used should have a very low copper content – Tillandsias do not like a lot of copper.
