Answer: These three plants like an evenly moist soil, but not a soggy soil. It is possible that you overwatered them, especially if they were growing indoors or in a heavy potting soil. These plants all like a lot of sunlight, and if grown on a windowsill may be leggy due to lack of light. If you have a sunnier window, or could put them outside, you might try that. So much of gardening is learning by trial and error, please don't be too discouraged.
