Fall Succulent Terrarium Guide

Fall Succulent Terrarium: the full guide

Everything from your workshop in one spot: how we built it layer by layer, the succulents you picked from, decor ideas from real guests, and how to keep your terrarium thriving well past fall.

The build, layer by layer

An open glass bowl has no drainage hole, so every layer has a job. Here's what each one does and why it matters.

  1. Pick 3 to 4 succulents

    Mix shapes and sizes: something tall or spiky, a round rosette, and a small filler. Before you plant, set them in the bowl while they're still in their pots and move them around until you love the layout.

    Why: Different shapes and colors give your terrarium depth. Testing first means no digging plants back up later.

  2. Add pumice for drainage

    Spread about an inch of pumice evenly across the bottom of the bowl.

    Why: With no hole in the bottom, extra water needs a place to go. Pumice holds that space so roots aren't sitting in a puddle, which is the number one way succulents get into trouble.

  3. Add your soil

    Add succulent soil on top of the pumice, about 2 inches deep. Build it a little higher toward the back.

    Why: Succulent soil is gritty and drains fast, which is exactly what these plants like. The slope gives your arrangement a natural hillside look and makes the back plants easier to see.

  4. Plant

    Squeeze the nursery pot, ease the plant out, and gently loosen the roots with your fingers. Shake off some of the old soil. Dig a small well, set the plant in at the same depth it sat in its pot, and firm the soil around the base so it stands on its own. Tallest plant first, toward the back, then work forward.

    Why: Loosened roots spread into their new home faster. Keeping leaves above the soil line prevents rot.

  5. Decorate

    Place your wood first since it's the biggest piece, then tuck in moss, pinecones, dried flowers, and any fall accents. Finish by brushing stray soil off the leaves and glass with a dry brush.

    Why: Big pieces first means small pieces fill in around them naturally, instead of fighting for space.

Arranging tips

  • Tallest in back. It anchors the whole bowl and keeps your smaller plants from getting hidden.
  • Think triangle, not line. Three plants in a loose triangle look like they grew that way. A straight row looks like a store shelf.
  • Pair opposites. Spiky next to round, green next to purple or powdery gray. Contrast makes each plant stand out.
  • Leave room to grow. About a finger's width between plants gives them space to fill out over the next few months.
  • Decor frames, plants shine. Let the wood and moss sit around your succulents, never on top of them. Leaves need light and air.
  • Spin it and step back. Turn the bowl all the way around. Every side is someone's front view.

Meet your succulents

Here are some of the varieties you may have picked from at your workshop.

EcheveriaThe classic rosette, shaped like an open flower. Comes in greens, blues, pinks, and purples.

HaworthiaSpiky with white stripes. One of the most forgiving picks, and fine with a little less light.
Photo: aloe
AloeLong pointy leaves with soft little teeth. Adds height and structure.
Photo: ghost plant (graptopetalum)
Ghost plantPowdery lavender gray rosettes. The powder is natural sunscreen, so handle it by the base.
Photo: sedum
SedumTiny bead or leaf clusters that spread. Perfect for filling gaps.

CrassulaStacked or jade-style leaves that grow upward. Great for a little height.

Decor inspo

Real terrariums from our workshops. Pick one idea or mix two. A few pieces placed with intention beat a full bowl every time.

Care at home

Succulents are easygoing. The two things that matter most are bright light and going easy on the water, especially in a bowl with no drainage hole.

Light

Pick your brightest window, ideally one with a few hours of gentle sun. East or south windows are great. Glass can heat up in harsh afternoon sun, so if your bowl sits in a hot west window, pull it back a foot or two. Stretching or leaning plants are asking for more light.

Water

Wait about a week after your workshop before the first drink so the roots can settle. After that, water every 2 to 3 weeks, only once the soil is completely dry. Use about a tablespoon per plant, poured slowly at the base with a spoon or squeeze bottle. Water even less in winter.

Check the glass

Your bowl is see-through for a reason. If you can see water sitting in the pumice layer, skip the next watering or two until it's gone.

Temperature

Normal indoor temps are perfect. Keep it away from heat vents and cold drafty windows, and bring it inside before nights drop below about 50°F.

Moss and decor

Lift out moss and dried pieces before you water so they stay crisp and don't mold. Wipe smudges off the glass with a dry cloth. When fall wraps up, swap in winter accents and your terrarium becomes a year-round piece.

Down the road

Turn your bowl a quarter turn every week or so for even growth. If it gets crowded, move a plant into its own pot in spring. Leaves that fall off can root on their own if you lay them on dry soil. Free baby succulents!

Plant troubleshooting

What you see What it means
Soft, mushy, or see-through leaves Too much water. Let the soil dry out completely and water less often.
Water pooling in the pumice More water than the bowl needs. Skip watering until it dries up, then use less next time.
Wrinkly or deflated leaves Thirsty. Give it a drink and it should plump back up in a day or two.
Stretching tall, pale, or leaning Not enough light. Move it closer to a bright window.
Crispy brown patches Sunburn, often from hot sun through glass. Move it out of direct afternoon light.
Fuzzy white spots on moss or wood Things are staying too damp. Remove the piece, let it dry, and water less.
A few bottom leaves drying up Totally normal. The plant is growing. Pull them off gently.
