There are 450 different varieties of air plants (Tillandsia), which are exceedingly unusual. Because they fall under the bromeliad family, which includes 3,475 primarily tropical plant species, air plants are linked to pineapples. They reside in various parts of the world, from the southern US to the top of Argentina. Xeric and mesic air plants are the two primary varieties. Compared to its tropical cousins, Xeric Tillandsia can survive in desert climates with less water and more sunlight (mesic Tillandsia).
In order to collect water that collects at their base, air plants attach their roots to other plants, rocks, and trees. For instance, in a tropical environment, they reside in the trees where they absorb water from the humidity and water that accumulates on the branches of the trees. They enjoy temperatures between 50 and 90 degrees Fahrenheit because they are accustomed to the rainforest and warm desert climate (1032 C). While xeric Tillandsia favor dry air, mesic Tillandsia prefer humid air. There are techniques to recreate that atmosphere, and air plants are fairly hardy, so don’t worry if you don’t live in a region with their ideal circumstances.
They are available in a wide range of colors and sizes. Sizes of different air plant species range from two inches to seven feet. The sizes of the types that are often found in stores range from two to five inches. There are certain types that produce blooms, but this typically means that the plant’s life cycle is about to come to an end. Before they pass away, air plants discharge pups, which are young air plants that develop into identical adults. To find out more about growing additional air plants from the original seedling, see the propagation section.
How high can air plants get?
Despite having an alien appearance, air plants are indigenous to the Americas and can be found from southern United States to Argentina. In the wild, they hang from tree bark using their roots to feed on bird droppings and rainwater that they have absorbed through their leaves. The air plant, commonly known as a Tillandsia, is one of more than 600 species and variations.
They typically feature rosette-shaped leaves that resemble straps, with new growth emerging from the plant’s center. Some plants have flowers that are red, pink, or purple and endure for a few days to a few months. The leaves can be silver, green, prickly, or fuzzy. The majority of air plants are small, growing 2″ to 12″ tall.
What is the growth rate of air plants?
Air plants can be divided into two categories: mesic and xeric. These classifications distinguish tillandsias from two quite different types of habitats. Xeric tillandsias often develop more slowly than air plants from the mesic group.
Tillandsias that are xeric grow in hot, dry conditions naturally. They appear fuzzy because they have more trichomes, which are holes on leaves that absorb water.
Since there is less water available in hotter settings, larger and denser trichomes enable them to absorb more water. They shield against the damaging effects of direct sunlight as well. These factors contribute to the slower metabolism and slower growth of xeric air plants.
On the other hand, mesic tillandsias are native to regions with regular rainfall and generally high humidity. They lack the silver/white fuzz, have less noticeable trichomes, and have a greener appearance.
Tillandsias from xeric regions have adapted to survive under these conditions. They require a lot of indirect sunlight at home (some may survive a few hours of direct morning or afternoon sunshine every day), as well as regular watering. Mesic tillandsias, however, require more frequent watering. They often develop more quickly than air plants in the xeric group.
Reason #2: Air plants are slow growers
Air plants develop slowly; in fact, they are among the slowest growing plants. It takes at least a month or two for air plant seeds to germinate, and another four to eight years for them to grow into full plants. For the first two to three years or so, their growth will be very sluggish.
Most people use pups to propagate air plants, however even pups take 2-4 years to develop. When you purchase medium-sized air plants, they frequently grow for a short time before giving birth to puppies (offsets). Pups eventually grow into independent plants and can be cut off from the parent plant when they are half as big.
The parent plant will blossom for the first (and only) time at this time, and then it will start to produce pups. Your tillandsia will be ready to reproduce at this point. The parent plant begins to deteriorate after producing pups.
If you keep the parent plant and don’t separate the pups from it, it will eventually grow into a lovely cluster. Just consider the fact that after a few years of growing, plants only ever bloom once. The parent plant then gives birth to pups, at which point its existence is done.
It will take between 12 and 16 months for a newly purchased plant to show noticeable growth. You should notice blossoming in one to three years.
Spring through mid-summer, followed by early fall through late autumn, are the warmest times for air plant growth. During the winter and the height of the summer, they won’t grow much if at all.
Reason #3: Lack of care
Despite their hardiness and low maintenance needs, air plants still need to be cared for. They need a lot of direct and indirect light, as well as watering (yes, tillandsias love water and cannot thrive without it). Additionally, your air plant won’t grow or thrive at all without adequate air exchange, hydration, and light.
A lot of light is needed for air plants, most often filtered light. Avoid subjecting them to intense direct sun for more than a couple of hours each day; doing so will burn the plant.
Air exchange is crucial as well.
Ensure that the room is ventilated once every day. If you’d like, you can also take your plants outside for a few hours each day (or at least few times a week). But don’t leave them in the air conditioning.
Watering is yet another crucial component. Watering air plants frequently is necessary. Less irrigation is needed for xeric air plants compared to mesic air plants.
During the warmer months, deep water your plants for an hour once every 10 days for xeric plants and once a week for mesic plants. Because they are prone to decay, certain plants don’t require deep watering (such as t. tectorum).
Running a lot of water over the plants for a short period of time under a shower or sink will also water them more frequently and less intensively. For mesic air plants, do this three times each week, and for xeric air plants, once per week.
Air plants won’t get enough water from misting alone. Every two to three days, you can spritz your air plants. However, at least once a week, you should soak or submerge them for extra deep watering sessions. Shake off any extra water consistently (you can even leave your air plant to dry upside down).
While this is a broad suggestion, the best course of action is to learn what each species of tillandsia requires.
Tip #1: Promote rooting
The beautiful thing about air plants is that you can exhibit them nearly anywhere by just arranging them on top of different things.
However, roots will be encouraged if you secure your air plants to fixtures that they ordinarily cling to in their natural habitat. Better roots will therefore encourage more rapid and superior growth overall.
To achieve this, you must secure your air plant to items like driftwood, wood, tree fern slabs, bark chips, and trees, among others. By encasing the base in moss, you can attach your air plants to those items.
After that, secure by wrapping the plant around the mounting device with some floral wire, as shown. You might need to do this by drilling holes through the display for the wire.
Tip #2: Fertilization
Fertilizing your air plant might assist if it’s not growing. Although air plants can survive without fertilizer, fertilizing your tillandsias is strongly advised.
By doing this, you dramatically increase the lifespan of your plant. Your air plant won’t thrive if you don’t fertilize it. Your air plants’ growth and coloring will both be enhanced by fertilizing.
In the wild, they actually take in nutrients from the nearby sources and decaying stuff (such airborne debris, dead leaves, and bugs). Through the trichomes on their leaves, they take in water-soluble nutrients.
We must use specially prepared tillandsia/orchid fertilizer/food because we don’t give our indoor air plants with natural sources of fertilizing at home. Fertilizers for air plants, like this weekly spray, frequently contain additional nitrogen and potassium for foliage development (new tab).
Tip #3: Provide favorable conditions
Make careful to offer your air plants the best conditions for growth and success. This includes plenty of filtered strong light (a terrarium cannot have more than one hour of direct unfiltered sunshine), excellent air exchange, and regular watering.
Make sure there isn’t a draft, but if it is near a window, ventilate the space once daily or move the plant outside for some fresh air (they love it).
To assist them tolerate more heat in the summer, deeply hydrate your air plants and lightly mist them in between. Your air plants won’t last very long if you keep them in showers or gloomy areas.
Do air plants ever get bigger?
There are many different varieties of air plants (Tillandsias). One of its most distinctive qualities is their range in size. In our greenhouse, we’ve seen Xerographicas the size of beach balls, Ionantha Mexican plants the size of your thumbnail, and everything in between. This list is for people who are looking for tiny plants. The following little air plants are ideal for use in tiny containers such as teardrop terrariums and globe terrariums. On our page for little air plants, you can find them all.
It’s vital to remember that all air plants are seedlings or pups, which are offsets at the base of the mother plant that appear after blooming. The plants mentioned below are likely to remain small and compact during their whole lives, nevertheless. Of course, there aren’t many air plants that are too big for a household atmosphere. On our website, we refer to size in terms like “little” or “big,” but these terms are all relative to the species in question. For instance, a large Ionantha Rubra will still be smaller than a little Xerographica.
One of the first air plants you will likely come across in your hunt for small plants is the Ionanthas, a particular variety of Tillandsia. Typically 1-3 inch tall plants with spiky foliage, Tillandsia ionanthas. They produce a lot of pups and, if let to spontaneously multiply, will form clusters. They naturally occur in Mexico, Central America, and South America. Elevation, climate, and conditions in each Ionantha’s native region account for the majority of the differences between them.
How much time do air plants last?
The growth rates of the various categories of air plants will have a considerable impact on how long your tillandsias live.
Xeric tillandsias, or the silvery-fuzzy varieties, are native to hot climates. They don’t need as much watering as mesic tillandsias, and they can withstand more intense lighting for longer periods of time.
Since mesic tillandsias (the greener varieties) are native to humid climates, they require more frequent and deeper waterings. Additionally, they naturally conceal themselves in the trees to avoid direct sunlight (but still lots of bright light).
It can be shown from a comparison of the two types of tillandsias that xeric air plants grow significantly more slowly than mesic ones. The air plant will take longer to mature, blossom, and generate pups if it grows more slowly.
Lifespan factor #2: Propagation method
The longevity of your air plant will vary depending on how it was propagated. Generally speaking, it contributes to the entire lives. Since growing from seed requires more time than growing from pups, pan.
It will take your air plant about two to three years to mature into a small plant if you start with seeds. It will take another 3-5 years to mature after that. If you start from seed, growth will be extremely sluggish during the first several years.
However, if it has had time to develop stronger, your plant may live longer than those that are cultivated from pups. Not always, but generally speaking, air plants developed from seeds will be more robust and healthy.
A new air plant will mature more faster if you start the growth of one from an offset. Typically, that is how your air plant was propagated whether you purchased it locally or ordered it online. It’s simpler and more practical. A mature offset will take two to three years to reach, bloom, generate new pups, and then die.
See this page for extra advice if the air plant you have doesn’t seem to be growing.
Air plant lifespan factor #3: Level of care
One of the key determinants of how long an air plant will last is how well you take care of it. Your air plant might not survive more than a few months if it receives poor care.
Keeping air plants in damp environments or overwatering them are two things that can lead to their mortality. In this situation, air plants don’t exhibit many or any symptoms for a while. When you pick them up or decide to water them again, however, they abruptly start to come apart.
Air exchange and lighting are also essential for air plants. Don’t store them in terrariums with lids. You still need to properly air the space even if you keep them in open displays.
A few times a week, taking the plant outside will be quite useful. Your plant needs a lot of indirect, bright light to survive and flourish.
Make sure to bring your air plant indoors when the temperature drops below 50 degrees Fahrenheit (10 Celsius). You need to water your air plant more frequently in the heat.
Lifespan #4: Nutrients and fertilization
Unbelievably, tillandsias in the wild receive nutrients from a variety of sources nearby. They take up nutrients from decomposing materials, withering leaves, airborne organic detritus, and even animal waste. Your indoor air plants can’t obtain those nutrients at home, therefore they don’t get them.
Although fertilizing your air plants is not essential, doing so will increase their longevity by months or even years. You can use a variety of fertilizers, including this spray, which needs to be applied once a week. Following product directions is essential since excessive fertilization might burn your plants to death.
Boron and zinc fertilizers should never be purchased as tillandsias are poisoned by them. Additionally, fertilizer needs to be water soluble so that your air plant’s trichomes on its leaves can absorb it.
Additionally, since bacteria in the soil are required to convert urea into useable nitrogen for plants, fertilizer must be urea-free. Due to a lack of soil, your air plants cannot perform this. Your plant will suffer early plant damage if you use those fertilizers.
How long do air plant blooms last?
Blooms on air plants can persist anywhere between a few days and 2-4 weeks. However, the blossoms of certain larger air plants, such t.xerographica, can continue up to a year.
Make sure not to soak or water your air plant at all if you want the bloom to persist longer. Because the bloom of an air plant cannot absorb water, watering it will cause it to wilt quickly.
Tillandsias only have one blossom in their lifetime, after which they produce pups and pass away. It usually blooms between one and two years after you get it, but this can vary.
