A succulent terrarium is one of the easiest, most forgiving miniature gardens you can make. These little glass worlds need almost no maintenance, look stunning on a shelf or desk, and let you grow plants even in the smallest home. Here’s a simple step-by-step guide to building one that lasts.
What You’ll Need
- An open glass container (succulents need airflow, so avoid fully closed jars)
- Small pebbles or gravel for drainage
- Activated charcoal (keeps the soil fresh)
- Cactus or succulent potting mix
- A few small succulents
- Decorative sand, stones, or tiny figurines
Step 1: Add a Drainage Layer
Since terrariums have no drainage holes, start with a layer of pebbles or gravel about an inch deep. This gives excess water somewhere to go so roots don’t sit in moisture and rot.
Step 2: Sprinkle Activated Charcoal
Add a thin layer of activated charcoal over the pebbles. It filters the water and keeps the closed environment from getting musty, helping your little garden stay healthy.
Step 3: Add the Soil
Pour in a few inches of cactus or succulent mix, which drains far better than regular potting soil. Leave enough room to nestle in your plants and still have space at the top.
Step 4: Plant Your Succulents
Gently remove succulents from their pots, loosen the roots, and tuck them into the soil. Arrange taller plants toward the back or center and smaller ones around them. Leave a little breathing room between plants so air can circulate.
Step 5: Decorate
Finish with a layer of decorative sand or small stones, and add any tiny figurines, crystals, or shells you like. This is where your terrarium gets its personality, so have fun with it.
Caring for Your Terrarium
Succulents need bright, indirect light, so place your terrarium near a window but out of harsh direct sun that can scorch through glass. Water sparingly, just a little when the soil is fully dry, usually every couple of weeks. Overwatering is the most common mistake, so when in doubt, wait.
Enjoy Your Tiny Glass Garden
A succulent terrarium brings a touch of living green to any room with almost no effort. Once it’s planted, it practically takes care of itself, rewarding you with months of beauty. Build one for your desk, your windowsill, or as a thoughtful handmade gift, and you may find yourself wanting a whole collection.
