These plants demand a soil pH between 6.5 and 7.0 and serious problems can arise if the pH dips below 6.5. Coir has a natural pH from 6-7 what suits perfectly. Fertilizers rich in calcium are also good for a Lisianthus plant. Optimal daytime temperature is between 20 to 24 degrees Celsius. Optimal nighttime temperature is between 16 to 18 degrees Celsius.
