Short answer
A soft, mushy stem on a Golden Pothos is almost always a sign of advanced stem rot caused by waterlogged soil. To fix this, you must immediately remove the rotted sections, prune away damaged roots, and repot the plant in fresh, well-draining soil with a pot that has adequate drainage holes.
When your Epipremnum aureum develops soft, mushy stems or a collapsing base, it is a serious warning sign that the plant's vascular system is failing due to excess moisture. Unlike common yellowing leaves, which might indicate minor stress, mushy stems indicate that rot has begun to decompose the tissue, posing a significant threat to the plant's survival.
Golden Pothos require their soil to dry out between waterings. If the roots sit in standing water or damp soil for too long, they lose the ability to take up oxygen and begin to decay, causing the mushiness to travel up the vine.
Check: Gently tip the plant out of its pot to check the roots; healthy roots should be firm and white or tan, while rotted roots will be black, slimy, and smell foul.
Fix: Remove all mushy, black roots and stems, sanitize your shears, and repot the remainder into a clean container with fresh, high-quality indoor potting mix.
Even if you water sparingly, using a heavy soil mix or a pot without drainage holes can keep the base of the plant saturated. Pothos vines are prone to stem collapse when the medium remains dense and prevents airflow to the root ball.
Check: Check the bottom of your pot for a drainage hole; if there is none, moisture is inevitably collecting at the base of the stems.
Fix: Replant into a pot with drainage holes using a soil mix amended with perlite or orchid bark to increase aeration.
In high humidity environments with poor air circulation, fungal pathogens can infect damaged stems. This often results in localized soft spots that rapidly spread across the vine base.
Check: Look for fuzzy gray or white growth on the mushy spots or distinctive dark lesions that don't appear to be caused by soil moisture alone.
Fix: Isolate the plant, remove the affected vines well below the mushy area, and improve air circulation around the remaining foliage.
When to worry
This is never merely cosmetic. A mushy stem indicates the plant is currently dying and requires immediate intervention to propagate healthy cuttings before the rot consumes the entire base.

Diagnose my Golden PothosNo, tissue that has turned mushy is dead and cannot recover. You should prune the vine back to the point where the stem is firm and green; if the base is mushy, you may need to take healthy top cuttings to propagate a new plant.
No, that virus is specific to pome fruits like apples. Your Pothos is suffering from standard root or stem rot related to moisture management, not a viral pathogen.
Always ensure your pot has drainage holes and wait until the top 2-3 inches of soil are completely dry before watering. Never let the pot sit in a saucer of excess water after a thorough soaking.
