How to Make a Terrarium- Step-by-Step Tutorial

Let me take you back to a lazy Sunday morning. I was sipping coffee, staring at my dull living room, thinking it needed a touch of green. But here’s the catch—I’m terrible with plants. Watering schedules? Forget it! But then, a friend mentioned terrariums, those self-sustaining mini-gardens. It sounded like the perfect solution, and the best part? You can make one in the afternoon! So, let’s dive in, and I’ll walk you through how to make a terrarium that’s not only easy to maintain but also a stunning addition to your home.

What is a Terrarium?

Before we get our hands dirty (literally!), let’s talk about what a terrarium is. It is a small, enclosed garden, usually made in a glass container. Think of it as your very own miniature ecosystem. It’s a fantastic way to bring nature indoors, especially if you’re like me and don’t have a green thumb.

Terrarium Making Checklist

Before you begin, let’s make sure you have everything you need. Here’s a simple checklist to guide you through the process:

Now that your checklist is ready, let’s move on to the fun part—creating your terrarium!

Creating Your Terrarium

Step 1: Choose Your Container

Quick story: I started my first terrarium with an old fishbowl I found in the garage. It wasn’t huge, but it was perfect for my first try. The key here is to pick something that suits your style. Open containers are easier to manage, especially for beginners. Closed containers, on the other hand, create a humid environment that’s ideal for moisture-loving plants.

Step 2: Layer the Bottom with Stones

Why stones? They create a drainage system so that water doesn’t sit in the soil and cause your plants to rot. Spread a layer of small stones or pebbles across the bottom of your container, about an inch thick.

Step 3: Add a Layer of Activated Charcoal

This is a crucial step, especially in closed terrariums. Activated charcoal helps filter the air and water, keeping your terrarium odor-free and your plants happy. Sprinkle a thin layer over the stones.

Step 4: Add Potting Soil

Now it’s time to add the soil. You want just enough to plant your greenery—about 2-3 inches, depending on the size of your container and the roots of your plants. Remember, not too much! We don’t want to overcrowd.

Step 5: Choose and Arrange Your Plants

Here comes the fun part—planting! Arrange your plants in the soil, starting with the larger ones first. Make sure to leave enough space between them for growth. If you’re using succulents, keep in mind that they need more light, so place them near the opening of a container with a lid.

Personal Tip: When I made my first terrarium, I went a little overboard with the plants. It ended up looking crowded, so I learned that less is more. You can always add decorative elements like moss or small stones to fill the gaps.

Step 6: Add Decorative Elements

This step is optional, but if you’re feeling creative, why not? To give your terrarium a personal touch, you can add tiny figurines, colored sand, or even small crystals.

Step 7: Water and Seal Your Terrarium

After planting, give your terrarium a light watering—just enough to moisten the soil. If you’re using an open container, you’ll need to water your plants occasionally. Closed terrariums are more self-sustaining and only need to be watered every few weeks.

Pro Tip: Watch out for condensation. If you see too much, your terrarium might be too wet. Just leave the lid off for a day or two to let it dry out.

Caring for Your Terrarium

Here’s where my experience comes in handy: I learned that terrariums are pretty low-maintenance, but they do need some care. Keep your terrarium in a spot with indirect sunlight, and make sure you’re not overwatering it. Succulents need more light, so if your terrarium starts looking a little dull, try moving it closer to a window.

Beginner’s Questions on How to Make a Terrarium Answered by Experts

1. How do I Prevent Mold in My Terrarium?

Mold is a common problem in terrariums, especially in closed ones. Make sure you’re using activated charcoal to help filter the air. Also, avoid overwatering and ensure your plants aren’t touching the sides of the container.

2. Can I Use Any Plants in a Terrarium?

Not all plants are suitable for terrariums. Choose small, slow-growing plants that thrive in the environment you’re creating—succulents for open terrariums and moisture-loving plants like ferns for closed ones.

3. How much Sunlight does my Terrarium Need?

Terrariums generally need indirect sunlight. Direct sunlight can cause the temperature inside to rise too much, harming your plants. Succulents need more light, so place them near a window, but avoid direct sunlight.

4. Do I Need to Fertilize my Terrarium?

Terrariums don’t need much fertilization. Too much fertilizer can cause your plants to grow too quickly, overcrowding the space. A light application once a year is more than enough.

5. Can I use artificial plants in my terrarium?

Absolutely! If you love the look of a terrarium but don’t want to deal with plant care, artificial plants are a great option. Just be sure to dust them occasionally to keep your terrarium looking fresh.

There you have it—a beautiful, low-maintenance terrarium that’s as fun to make as it is to admire. Whether you’re using it to brighten up your home or as a thoughtful gift, a terrarium is a perfect way to bring a little bit of nature indoors. Plus, it’s the perfect project for those of us who might not have the greenest thumbs. So go ahead, gather your materials, and start creating your own mini garden today!
