pot your plant!
Rule #1: Don’t leave your plant in the black plastic "grow" pot you bought it in.
Marino says, “Plants that are potted live longer, happier lives because they have better access to water, and their roots can continue to grow and not be pot bound in the black plastic grow pot.”
Look for a pot made of a substantial material, like a ceramic, stoneware, terra cotta, or fiberglass that is 2-3 inches larger in diameter than your fiddle’s plastic pot. (Marino says bigger pots tends to lead to overwatering, which is a no-no.) Drainage holes aren’t necessary.
how to pot your plant
While drainage holes might not be necessary, adding the right rocks to the bottom of your pot is. This will both protect the plant’s roots from excess water sitting in the bottom of the pot and absorb it. Marino recommends lava rocks mixed with gravel because of their porous qualities.
As for the soil, make sure to buy the variety made for indoor plants. Look for perlite and vermiculite on the soil bag—Marino says this mix will hold and keep water for the plant between waterings. If you plan on doting on your fiddle, spraying it with organic liquid fertilizer once a month will be a real treat. (The Sill is a fan of Fox Farms liquid fertilizers.)
what about watering?
You need to water your fiddle once week, for sure. Half a liter is good for the larger 5-7 foot fiddles and a bit less for the shorter, bushy guys. Another thing to remember: The air gets very dry in the winter, which is not at all like their natural habitat. Fake humidity by misting your plant with water once a week—if not year round, then definitely in the winter. This can be done at the same time you water your plant.
