Have you seen those neat balls of air plants hanging in a greenhouse and ever wondered what they were? These are actually air plant clumps that are formed from multiple offsets ( pups) that are growing together! Or maybe you want to grow a clump of your own. Read on for some tips on growing an air plant clump, and some photos of some pretty impressive air plant clumps that we have had over the years!

Let’s start from the beginning. To summarize, an air plant’s life cycle is at its pinnacle when it blooms, and will soon send its energy to creating pups or as we like to call them air plant babies!

So the first rule of thumb with propagation is to continue caring for your air plant as you normally would; giving your plant adequate sunlight and water. This is also a good time to fertilize!  Normally we would recommend removing the pup when it is about a third of the size of the parent plant, but in this case, leave it! Some plants produce more than one pup at a time as well!

It can take a while to form a clump so be patient! As the pups begin to grow, they too will flower and eventually produce pups. If left to grow naturally in this way, they will form a clump!

Some plants are more prolific clump producers than others, including the ionantha, ionantha vanhyningii, schiedeana, houston enano, and stricta, among others.

Some plant clumps lend well to being hung by wire which encourages them to grow in a spherical shape, but they can also be mounted to a piece of wood, or left to grow unmounted. We have had great success in growing T. ionantha clumps on wires.

So to get your air plants to begin growing towards a clump:

  • Continue caring for your plant as normal, giving it adequate sunlight and water
  • Fertilize once a month ( We have fertilizer available in our shop)
  • Allow pups to grow instead of removing them 
  • Use wire to hang the clump to promote a spherical shape
