The leaves of a Sansevieria Trifasciata may turn yellow due to several reasons. One of the major reasons is fungal infection. Fungus that grows in the soil, especially if the soil is moist, can cause root rots and make your plant wilt and turn yellow. Another reason is nutrient deficiency. This can be caused by using a poor quality soil mix or by using pots that prevent the roots from absorbing the water and nutrients from the soil. The lack of nutrients can also be caused by overwatering. You can fix this by repotting your Snake Plant in a suitable soil and using clay pots that allow aeration of the soil. You can also use effective fungicides and disinfect the soil mix and pot.
