For the Martha Stewarts of the world, caring for a houseplant is as easy as boiling water. But what if the only thing you’ve ever been able to grow is mold in the back of your fridge?
When it comes to coaxing your nearly dead fern back to life, David Trinklein, an associate professor of plant sciences at MU, says never fear. “I don’t think there’s a person who can’t be properly taught to grow a plant if they have the right environment,” he says.
The environment is the key. Most houseplants are native to rainforests and love high humidity. So unless you keep your fern in a sauna, its current indoor home is as natural as a pine-tree air freshener.
However, there are some plants hardy enough to survive low light and low humidity, the natural environment of humans. Steve Boyd of Lari’s Flowers suggests woody stem plants, such as palms. Leafy green plants known as cast-irons are able to tolerate almost any condition. Cast-iron plants are literally harder to kill than to keep alive. “If you can’t grow a cast-iron plant, you ought to try plastic,” Trinklein teases.
However, be wary of loving your plant too much. Don’t try to give it the eight glasses of H2O you drink every day: Overwatering is the No. 1 killer of houseplants. Usually this happens because roots continue to suck water pooled at the bottom of the pot. Guilty of being overzealous? There are some plants, including the African violet, that love having what are called wet feet and thrive under such conditions.
All plant owners, though, should avoid watering with softened water, which has high sodium content. Trinklein calls this the kiss of death. Although soft water will leave fewer mineral stains in your bathtub, the extra salts build up and draw the water from the roots and cause them to shrivel. Think of plants in this condition as akin to pickles, but they won’t taste like kosher dills. To avoid this, use distilled or bottled water.
Boyd says he sees houseplants in horrible condition all the time. Sometimes it’s best to just start over. But don’t worry; it’s still possible to turn your brown thumb a little greener.
“People should not be threatened by the prospect of growing a plant,” Trinklein says. “It should bring joy and contentment. If one does lose a plant (from) time to time, that’s nature.’’
And hey, if all else fails, you can always go faux.
