Short answer
Snake plant root rot is almost always caused by overwatering or poorly draining soil that keeps the rhizomes constantly wet. The single most common fix is to remove the plant from its pot, trim away all mushy, black roots, and repot it into a fast-draining succulent mix in a container with drainage holes.
Root rot in Dracaena trifasciata typically manifests as soft, mushy, or translucent foliage starting at the soil line, often accompanied by a foul, swampy odor emanating from the pot. Because snake plants are succulents that thrive on neglect, seeing these symptoms is a serious red flag that requires immediate intervention to save the plant.
Snake plants store water in their thick leaves and require their soil to dry out completely between waterings. Watering more than once every three to four weeks often leaves the root system sitting in an anaerobic environment, leading to rapid tissue decay.
Check: Gently lift the plant from the pot; if the soil is sodden and the roots feel slimy or detach easily when pulled, you have confirmed rot.
Fix: Stop watering immediately, remove all decayed roots with a sterile knife, and repot in fresh, dry, porous succulent soil.
Even with sparse watering, using dense, peat-heavy potting soil or a pot without drainage holes will trap moisture around the base. This species is highly susceptible to rot when the root zone cannot breathe or drain excess water.
Check: Check if water pools on the surface for a long time after irrigation or if the pot lacks holes at the bottom.
Fix: Replant into a terracotta pot with drainage, using a mix of 50% potting soil and 50% perlite or pumice to ensure rapid drainage.
While snake plants are touted as low-light survivors, they use much less water in low-light conditions. When placed in deep shade, the soil stays damp for weeks, which can induce root rot even with an otherwise normal watering schedule.
Check: Observe the soil; if it takes more than a month to dry out completely, the plant is not receiving enough light to drive photosynthesis and water uptake.
Fix: Move the plant to a brighter location with indirect sunlight to increase the plant's metabolic rate and evaporation from the soil.
When to worry
You must act immediately the moment you notice the base of the leaves becoming soft or yellowed, as this indicates the rot has likely moved from the roots into the main rhizome. If the entire rhizome has turned black and mushy, the plant is typically beyond saving.

Diagnose my Snake PlantYes, if you have leaves that are still firm and healthy, you can cut them off, let the cut end callous for 24-48 hours, and then propagate them in fresh soil or water.
Fungicides are generally unnecessary and ineffective for snake plants; addressing the moisture issue through physical removal of dead roots and better drainage is the only reliable cure.
Wrinkled leaves usually indicate dehydration because the damaged, rotted roots can no longer take up water to hydrate the foliage, making the plant look 'thirsty' despite being in wet soil.
