How-To: Building a Woodland Terrarium

Building your own terrarium from moss and plants you have harvested yourself can not only be lot's of fun but also very rewarding. It will keep you looking for different varieties and will get you to see things you may not have noticed on an afternoon hike. I have found interesting bugs, eggs, mushrooms and animals, just to name a few. The terrariums I made yesterday were entirely constructed from wild moss I picked up that morning. With the wet conditions, the moss had flourished and was easy to harvest. Whenever you pick anything for transplant it is better to do so when well watered. If the roots are dry they may not take to the new potting medium. Moss is quite possibly one of the easiest to gather, gently work your finger tips between the moss and the object it is growing on (stone, tree, earth, etc...) and pull it up in a sheet or clump. Place the moss in a Ziploc bag (fold root side in if needed) and seal. Toss in your bag and keep looking for other items you might like (small stones, pieces of driftwood, bones, etc...) After you have found what you like and will need, head home to start on the terrarium. To prepare the moss you will want shake the sheet out into a garbage bag or bin or bathtub. Leaves, bugs and other debris should fall out. Don't worry about getting all of it out, you can get it at the end.

You'll need a clean, large glass container with a loose fitting lid. Cookie and apothecary jars work and look best. Look at rummage sales, thrift stores and if all else fails Wal-Mart carries pretty inexpensive jars like the ones shown in this How-To. I bought these years ago and believe they were about $12 or so. Really not a bad deal. You might want to have a few handy because once you get going it's hard to stop yourself. Chris is worried and he should be! I have completely mentally redecorated the apartment to incorporate as many terrariums and plant life that I can but that's for another time. SO with your jar spotless and rinsed thoroughly place about an inch of cleaned gravel in the bottom. I buy the $2 bags of river pea gravel from Home Depot and that looks just fine for me. If you want color you can use aquarium gravels, glass blobs or rubies and sapphires if that's what you want, you just need a 1" layer of pebble-ish stuff at the bottom for drainage.

Next we need earth! I use a regular high quality potting soil but you can also use specialty mixes like those for African Violets or Orchids. In a large bowl place the estimated amount of soil needed (there should be at least 1 1/2"-2 1/2" of soil and you will need more if you plan on making hills.) Next add in aquarium or gardening charcoal, about a 1:5 charcoal to soil mix is sufficient. The charcoal will purify the terrarium over time, keeping it fresh and healthy. Add in enough water to completely wet the soil. You don't want mud! Just enough where you can make a mud ball and it doesn't fall apart. Place into the container on top of the gravel (don't mix the two.) Be as neat as possible trying to mind the walls of the container. I like to make mounds of dirt to create hills and valleys to add visual appeal. After you have the base to your liking, take a fork and rough up the surface so the roots will take. Using a spray bottle filled with water and set on "Stream" spray down the sides of the container making sure to get all the dirt down to the bottom.

Now the fun starts. I pull several different varieties of moss that I collected trying to change up the color, texture and size. I love how fern moss looks like a forest from far away and clump moss takes on the appearance of a meadow. You can gently ease pieces off your main sheet of moss or puzzle together small sections you have. Press the moss firmly into the prepared soil. If you are using a longer moss like fern moss, lay it on last so the bottom leaves can hang over and not become smothered by other mosses. If you are planting ferns or other plants, make sure to dig a little hole for them first. It is better to put the plants in first and lay the moss around them. After all the living objects are in place you can add anything decorative you found or like (skulls, driftwood, jade statues, rocks, etc...) To finish up mist down entirely, spraying off any debris on the walls of the container. Don't go overboard with the water, if you see it pooling in the gravel stop. You don't want it to be too wet. Look through and pick out any debris or bugs hiding in the plants. Now place the top on and set in a low light area of your house to enjoy.

For the next week or so after you'll need to monitor the moisture levels. If there was originally water pooling in the gravel, leave the top off overnight. Then put it back on the next morning. If condensation starts to appear on the walls, take the top off again. If the soil looks dry, lightly mist down the plants. It will take some time but once the humidity is up without the glass fogging up, you can leave the top on and pretty much forget about it. Occasionally you will need to mist and prune but that is almost bi-annual. Really easy right? Make several, start big, it's just easier.
