Top 5 Reasons your Terrarium Plants Keep Dying

1. Overwatering: Turn That Terrarium Lake Back Into Land

Anyone else feel like they need a degree in hydrology just to keep their terrarium happy? Overwatering is probably the number one cause of plant demise in terrariums. You think you’re doing them a favor by giving them a drink, but turns out you’re pretty much waterboarding them.

Why Overwatering Happens

Too Eager: You’re just so excited about your new green babies, you forget they’re not camels and don’t need to hoard water.
Lack of Drainage: Most terrariums don’t have drainage holes, making it literally impossible for excess water to escape.

Remedy: Less is More

Check the Soil: Poke your finger into the soil. If it feels dry an inch down, it’s time to water. If it’s still wet, put down the watering can and back away.
Gravel Layer: Add a layer of gravel or charcoal at the bottom to improve drainage. Think of it as the terrarium’s personal spa stone treatment.
Plant Sitter: Consider outsourcing! Find a friend with a green thumb and bribe them with cookies to take over watering duties.

2. Poor Lighting: Plants Aren’t Vampires

Maybe your terrarium sits on a shelf as dark as a cave. Plants need light, and unless we’re crafting a Dracula-themed terrarium, darkness won’t cut it.

Why Poor Lighting Happens

Bad Window Spots: You think that dark corner really brings out the gothic aesthetic.
Indoor Life: Well, the sun is too mainstream, right?

Remedy: Let There Be Light

Natural Light: Move your terrarium to a spot that gets indirect sunlight. Like a gentle morning sunbeam, not a solar death ray.
Artificial Lighting: Invest in a grow light. If your plants were on Instagram, they’d call it their ring light.
Light Tracking: Use a light meter app on your phone to see if your plants are getting enough lumens. Yes, you’ll look like a plant paparazzo, but it’s for a good cause.

3. Wrong Plants: It’s Not You, It’s Them

You wouldn’t put a polar bear in the Sahara, would you? Some plants just aren’t cut out for terrarium life, no matter how many inspirational quotes you whisper to them.

Why Wrong Plants Are Chosen

Impulse Buying: That cactus looked so cute, how could you resist?
Misinformation: That lovely lady at the plant store swore up and down that the fern would thrive. She lied.

Remedy: Know Thy Plant

Research: Look up plants that are specifically known to thrive in terrariums. Think ferns, mosses, and air plants.
Ask an Expert: Visit a botanical garden or a local nursery with specialists. They won’t sugarcoat the fact that putting a rose bush in a terrarium is a death sentence.
Plant Compatibility Chart: Create or consult a compatibility chart. Matching the right plant to the right environment is like perfecting a matchmaking algorithm for Tinder—complex, but worth it.

4. Poor Air Circulation: Plants Need to Breathe Too

Your plants are not hosting clandestine speakeasies; they need airflow. In a closed environment, humidity can skyrocket, leading to mold and rot.

Why Poor Air Circulation Happens

Sealed Containers: It looks cool, but it’s basically a suffocation chamber.
Too Cozy: You’ve crammed so many plants in there; there’s no room left to breathe, let alone grow.

Remedy: Ventilation Vacay

Air Holes: Drill small holes in the lid for ventilation. No, your terrarium won’t turn into Swiss cheese, but thank you for asking.
Open Lid: Take the lid off occasionally to let some fresh air in. It’s like a mini-vacation for your plants.
Right Size: Make sure your plants have enough room to grow without squishing each other into oblivion.

5. Pests: Tiny Invaders, Big Problems

You might need to call upon your inner Sherlock Holmes to figure out this one. Pests can wreak havoc in your tiny Eden, turning it into a battleground worthy of an insect-scaled “Game of Thrones.”

Why Pests Invade

New Plants: Sometimes, new plants come with unwelcome hitchhikers.
Humidity: Too much moisture can attract all the wrong kinds of guests.

Remedy: Declare War

Identify: Figure out what kind of pests you’re dealing with. Whether it’s aphids, mites, or some unholy hybrid.
Natural Predators: Introduce ladybugs or other natural predators if they’re suitable for your plant types.
DIY Spray: Make a gentle spray of water and dish soap to deter pesky invaders. It’s the horticultural equivalent of sending them a strongly-worded letter.
Quarantine: Isolate the affected plant immediately. Plants need social distancing too.
