Place Oxalis clovers in bright indirect light and water once top two inches of soil is dry! These plants can tolerate some morning sunshine, but prefer filtered light. If the air is dry, mist the area frequently or use a humidifier as your Oxalis likes a humid environment.  The ideal temperature range for your Oxalis is between 65 and 75 degrees. They are unable to withstand heat above 75–80 degrees. During the spring and summer, feed your Oxalis once a month with an all-purpose houseplant fertilizer.
