Leave it to the French to find a decorative solution to frost-bitten foliage.
The glass cloche was originally used to protect frost-tender plants in the garden, but these old-fashioned bell jars are useful -- and simply charming -- for your indoor garden, too.
Cloches act as mini-greenhouses, containing humidity given off by plants, as well as protecting them from drafty heat/AC vents -- often the cause of dry air indoors.
Growing plants under cloches is ideal for small tropical plants that crave high humidity.
Ferns, soft-stemmed tropicals and carnivorous plants thrive in a moist, warm environment, making them good candidates for living under glass.
African violets like a humid atmosphere. But if you're going to put one under a glass cloche, keep an eye on it. Like many flowering plants, it's prone to mold if enclosed for long. Allow good air ventilation by placing a small rock under one edge of the cloche. Or you can simply lift the cloche for a few minutes each day to clear any condensation that builds up on the glass.
Keep your cloche-covered plants out of hot, direct sunlight. Your tender tropicals can't take the heat. Temperatures can soar under glass, "cooking" your plants within a short time.
The amount of water in the air is measured as relative humidity -- and tropical plants need more than most. Native to tropical rainforests, these house plants prefer higher-than-average levels of relative humidity -- 70-80% will make them feel at home.
How do you know if your plants are getting enough humidity? You'll see signs that your plant is suffering in dry air -- dry, brown leaf tips, flower buds falling off, or brown scorch marks on foliage.
These glass bell jars provide an ideal micro-climate for many small, humidity-loving tropicals. They also make easy, temporary covers for growing seedlings and propagating your house plants.
Show off your small house plant under glass by placing it on a plant stand. A traditional-style pedestal will complement the old-fashioned charm of the garden cloche.
