One of the best things about air plants is that they require minimal maintenance as compared to many other house plants. However, this doesn’t mean that they are maintenance-free, and just like with most plants, the three main factors that can affect their health and life span are: air, water and light. We’ve talked fairly extensively about watering your air plants, so today we’ll talk a bit more about light.
In general, tillandsias (AKA air plants) prefer bright, but indirect, filtered light. We recommend either south or north facing windows as opposed to east or west, as these tend to get more indirect light.
We’ve experimented with air plants throughout our house and the ones that seem to do best are near our kitchen window, which is partially shaded by outside trees – so they get plenty of natural, filtered light.
The humidity of your environment can also dictate how much direct light air plants can handle. In general, if your air plants are living in a more humid environment, they will be able to handle a bit more sunlight since they will not dry out as quickly. For example, air plants living outside in the humid Florida environment can often do OK with more sun.ost air plants do not do well with direct or full sun.
Because they require indirect light, air plants make great office plants as long as they get some light, either indirectly from a window source, or artificially from full spectrum fluorescent lights.
Of course as with anything in nature, there are exceptions. Some of the silver-leafed air plants can handle more direct sunlight. The great Xerographica air plant is one of the few tillandsias that can take full sun (read more about the Xerographica here).
We recommend that you experiment with positioning your air plants in different lighting situations to see how they respond best. Where have you seen your air plants thrive the most? What lighting has NOT worked for your air plants?
