10 Things to Know About Air Plants (Tillandsias)

10 Things Nobody Tells You About Air Plants (Tillandsias)

Air plants, or Tillandsias, have captured attention for their beautiful forms, vibrant foliage, and unique ability to grow without soil. Despite their popularity, there’s a lot most people don’t know about growing and caring for these fascinating epiphytes. Read on for the top ten things nobody tells you about air plants—and discover how to keep them thriving as striking features in your home or garden.

1. Air Plants Still Need Water

No, air plants do not live on air alone. While it’s common to see them marketed as “no-maintenance,” these plants require regular hydration. Air plants absorb essential moisture and nutrients through specialized cells on their leaves, not their roots. Neglecting to water them leads to shriveling, browning, and eventual death.

• Watering can be done by misting daily, dunking or soaking weekly, or a combination of both, depending on your climate and the air plant’s species.
• Higher temperatures, bright light, and dry conditions mean more frequent watering. In steamy bathrooms or humid climates, less frequent water is needed.

2. They Hate Sitting in Water

Unlike traditional houseplants, air plants will rot if left sitting in water or if excess water is trapped between their leaves or in their crown. Any water that pools at the base may encourage rot, which is fatal for these delicate beauties.

• Always shake off excess water after soaking or misting, and let them dry completely within four hours in a spot with good air circulation.
• Display them so water can easily drain and dry—for example, upside down on a towel.

3. Don’t Plant Air Plants in Soil

Do not pot your air plant in soil: it suffocates their unique root system, whose only purpose is to anchor the plant in place—never to take up nutrients or moisture. Soil retains too much water, which leads to rotting.

• Display your Tillandsias perched on decorative stones, shells, driftwood, or mounted onto bark, as you would see in their native habitats.

4. Light and Air Circulation Matter

Bright, filtered natural light is ideal. Fluorescent or grow lights also work, so offices or darker spaces can enjoy air plants as well. Full direct sunlight for extended periods will scorch their leaves, especially during midsummer or with thin-leaved species. Good air movement is essential after watering and for overall plant vitality.

• Ideal light: Near an eastern, western, or bright northern window, or beneath strong artificial lights.
• Avoid: Dim corners, sealed terrariums without vent holes, or sitting directly on heat vents.

5. They Flower Once (But Pups Live On)

Each air plant blooms just once in its lifetime, usually after reaching maturity. Their inflorescences are often brightly colored and can last from a few days to many months, depending on species. Post-bloom, the plant will gradually decline, but as a parting gift it produces pups—offsets or baby air plants that can be separated and grown on.

• Wait until pups are at least a third the size of the parent before gently pulling or cutting away, allowing each to develop fully.
• Clusters are possible and make for eye-catching displays.

6. Water Quality Counts

Tillandsias are sensitive to water with high mineral or chemical content. Chlorine, fluoride, and hard water can damage their delicate leaf scales (trichomes).

• Use rainwater when possible. If not, let tap water sit out for a few hours to let chlorine dissipate, or use filtered water.
• Avoid softened or distilled water unless you supplement with occasional fertilizer, as distilled water alone can leach nutrients from the plant over time.

7. Fertilizing Makes a Difference

While air plants can get by without supplemental food, they thrive and produce more robust growth, flowers, and pups when given the occasional boost. Use a fertilizer specially formulated for bromeliads or air plants, diluted to at least one-quarter of the recommended strength.

• Fertilize once a month during spring and summer, mixed into your soak or misting water.
• Over-fertilizing can burn the plant’s leaves, so err on the side of less rather than more.

8. Diversity in Shape, Color, and Habitat

There are over 600 species of Tillandsias, with a huge range of sizes, textures, and shades—from the silvery, fuzzy-leaved species that hail from dry deserts to the lush, glossy green forms found in humid forests.

• Use this diversity to mix species for living art installations—combine upright, spiky varieties with those that drape or curl. Each brings a unique look.

9. Display Options Are Nearly Endless

Because they don’t require soil, air plants can be displayed almost anywhere with adequate light and airflow, limited only by your creativity. From terrariums, glass globes, and driftwood to shells, magnets, wreaths, or wall frames—the sky’s the limit.

• For long-term health, avoid sealed containers unless opened frequently for air exchange and drying time.
• Try natural-finished wood, cork, or stone. Avoid copper wire or treated wood, as these can be toxic to Tillandsias over time.

10. Common Myths and Mistakes

A few persistent myths and mishaps continue to lead to air plant woes. Here’s what new air plant owners should watch out for:

• Myth: Air plants don’t need water at all.
  Reality: All air plants need hydration. Misting is not always enough, especially in dry homes; regular soaking is often best.
• Myth: They want direct sun like succulents.
  Reality: Filtered, bright light is best. Avoid harsh direct sun for most species.
• Mistake: Potting in soil or sand.
  Tip: Mount or perch with no soil needed.
• Mistake: Letting water pool or plants dry completely out.
  Tip: Prioritize both drainage and regular watering.

Additional Tips for Happy Air Plants

• Trim any brown or dried leaves at their base to keep the plant tidy and healthy.
• Do not trim roots unless absolutely necessary—they help anchor your plants.
• Rotate plants periodically to ensure all sides receive light.
• If leaves curl drastically inward or feel tough and wiry, your air plant is thirsty.
• Avoid sitting plants directly on heaters, air conditioners, or in consistently drafty spots.

Frequently Asked Questions (FAQs)

Q: How often should air plants be watered?

A: Typically once per week by soaking, supplemented by misting 1–2 times a week. Adjust frequency for dry homes, higher temperatures, or thinner-leaved species.

Q: Can I use tap water for my air plants?

A: Tap water is generally fine, but let it sit out for a few hours before use to dissipate chlorine. Rainwater, well water, or filtered water are best. Avoid softened or overly hard water.

Q: Do air plants need to be fertilized?

A: Monthly feeding during the growing season (spring and summer) with a dilute air plant fertilizer can encourage blooms and pups, but is not strictly necessary.

Q: Should I trim my air plant’s roots?

A: Roots serve as anchors rather than nutritional organs. Most trimming is unnecessary unless for cosmetic reasons or if the roots are damaged.

Q: Can air plants be displayed in closed terrariums?

A: It’s better to avoid sealed terrariums. Without airflow and time to dry after watering, air plants can quickly rot. Choose open containers or mountings that let air circulate freely.
