Terrariums are back in style and they’re a fun, easy way to grow and showoff your plants. Terrariums are made of glass and are generally enclose or have a few holes in the cover to provide fresh air. The glass cover traps humidity and recycles it as water, keeping waterings to a minimum. Air holes allow air to circulate and keep the condensation down so that you can see the plants. If your container’s lid doesn’t have air holes, just take the top off from time to time. This is a great way to grow ferns indoors because they need humidity to thrive.
You may not be familiar with hydrostone, a product used for the base layer. It’s a soilless growing media that feels like pumice. It helps deliver the perfect balance of air and water to your plants. It’s a 100 percent recycled product, made in the United States.
Begin by adding a one inch layer of hydrostone in your glass container. Top that with a solid layer of sphagnum moss. This helps hold the soil in place and keeps the stone layer looking clean. Next, add an inch or so of Espoma’s Potting Mix.
Choose your plants. Laura uses maidenhair ferns because they require a high level of humidity, which work perfectly for this type of container. Birds nest ferns and staghorn ferns also work well and look terrific with the curly foliage of the maidenhair ferns. Fern displays are all about texture. Gently remove the plants from their pots and shake off as much soil as you can before nestling them into the new container. Top with a bit more potting soil if necessary.
Decorate the top layer with more moss, rocks, miniature fairy garden figures or natural products like pinecones. Whatever you think will look beautiful is the best choice. Leave one little spot of the top soil open. This way you can look at it to gauge how wet or dry the soil is. Mist soil lightly.
At first, it’s a good idea to check your container once a week for watering needs. In general, they’ll only need water about once a month but each terrarium is slightly different. Don’t kill it with kindness, in other words, don’t over water it. Set your new creation in bright light but not direct sun light as the glass can act as a magnifying glass creating too much heat. Fertilize every other month with Espoma’s Indoor! Liquid fertilizer. Now, sit back and enjoy your very chic looking new art project.
