What's wrong with my air plant (Tillandsia)? We get this question often from customers and even folks just visiting our site looking for information about caring for their air plants. While knowing exactly what happened to the plant can be tough, looking at the "big picture" can sometimes help us figure out what went wrong and make the proper adjustments.
To start, we need to look at what type of plant you have and take into account its natural growing habitat. Is it a green leafed plant that's more mesic? Or is it a silver leafed plant that is more xeric? This is an important question, because it will help determine the type of care you should be giving your plant and what environment works best. Check out our Mesic Vs Xeric article to learn the difference between these types of plants. A good rule of thumb is that green leafed/ mesic air plants are going to like more moisture and less sunlight versus a silver leafed xeric plant like the xerographica. Keep in mind that some air plants can fall in between these classifications, so labeling plants mesic or xeric is not an exact science. It does however give you a little clue into the ideal environment for your type of Tillandsia and ultimately the care you should give it.
Most issues with Tillandsia (air plants) stems from incorrect care for the type of plant and its specific needs. Too much moisture for a plant that likes arid and dry conditions will ultimately end up with issues. Same goes for air plants that like a lot of moisture like the brachycaulos or stricta, you would need to water these plants more than a silver leafed xerographica or it will gradually dehydrate and you will begin to see dry and brown leaf tips as the plant eventually shrivels up and dies from dehydration. We surely dont want that!
Once we have figured out the ideal natural environmental conditions, you should be able to figure out where you differed in the care which caused the issues and you can adjust accordingly. Whether it be more or less water, more or less sunlight, etc.
While incorrect care is a large part of why people have air plants that die, there are also many other factors that can come into play. Things like light, water, and air are all very important to the survival of your air plant. For more in depth care instructions, visit our air plant care page. Remember that air plant care guidelines are just guidelines, and there is no magic formula that works for everyone. Your specific needs will vary depending on all the different aspects we discussed above.
Below we have compiled a working list of questions/concerns we get from customers and visitors to our website. Our hope is to be your online Air Plant Source, and to not only provide quality air plants and products but to also to provide information and serve as an educational tool for air plant collectors all around the world.
If your air plant is turning yellow, it can be caused by too much light or too much water. When a plant turns yellow, it is saying "help!" Cut back on watering and if your plant is in an area with direct sun, move it to an area of more indirect light. Yellowing can also be caused by over fertilization or copper poising. Exposure to cold temperatures can also cause yellowing of the plant, which will happen before it gets mushy and ultimately dies.
Brown spots can be caused by many things. One of the most common causes is from too much sunlight and the plant is sunburned. This can be amplified if the plant is wet and getting too much direct sunlight. Another source of brown spots can be from over fertilizing. Fertilizer can burn your air plant's leaves. Brown spots can also be from a pest, or from the plant getting stressed in transit, especially if it is cold where you live. Lastly, brown spots can be a sign if fungus or mold starting such as a brown leaf spot disease. If this is the case you can try to spot treat with a fungicide that is formulated for roses. This type of fungicide will have no copper and be low in sulfur.
After an air plant blooms, the plant most often produces a pup or offset. You might notice that the mother plant starts to wilt or die off which is perfectly normal. Some plants produce more pups than others and may survive longer, while others might wither away once the pup is large enough to survive on its own. Learn more about pups in our article about air plant propagation.
While this is hard to say without seeing a picture, the answer is likely trichomes! Trichomes are small cells on the leaf of tillandsia (air plants) that assist in water collection and protection from being burned by sunlight. Some xeric varieties like tectorum will have an abundance of trichomes that is very noticeable while other mesic varieties like bulbosa will have trichomes that are almost unnoticeable. We have several articles to learn more including All About Trichomes and a follow up article Trichomes In depth which also discusses the CAM process air plants go through.
