The substrate should dry completely between waterings and the pot should always have good drainage. to avoid flooding.
Lack of light
La Sansevieria needs bright indirect light to thrive. If you place it in low-light areas or far from windows, its leaves will turn soft and paleThis happens because the plant cannot carry out photosynthesis properly, becoming progressively weaker.
Inadequate temperatures
Sansevierias prefer warm temperatures, between 18°C ​​and 30°C.Excessive cold can soften its leaves and even cause irreversible damage. Avoid placing it in locations exposed to cold drafts or sudden temperature changes.
Substrate and pot problems
A compacted or moisture-retaining substrate makes it difficult for healthy roots to develop. Use cactus or succulent mixes that are airy and have excellent drainage properties.. The pot should also allow excess water to escape and be suitable for the plant's size.
How to Recover a Soft-Leaved Sansevieria: Step by Step

- AphidThese tiny insects often appear on weakened houseplants. Remove them manually or use organic insecticides.
- Root rot and fungal diseases: The fusarium and other fungi appear due to excess moisture. If you notice brown spots or soft areas at the base, remove the plant, eliminate the affected roots, and apply a fungicide.
- Anthracnose: It manifests as brown spots bordered by darker colors on leaves and stems. It is important to use organic fungicides and improve ventilation around the plant.
Additional care for firm, healthy leaves

- Leave water in the dishEmpty the saucer from the pot 15 minutes after watering to prevent the roots from remaining submerged.
- Do not remove damaged leaves or roots.Soft tissue acts as a source of infection. Cut through it with clean tools.
Can the soft leaves of Sansevieria be recovered?
Not all soft or wrinkled leaves will regain their plump appearance. If the leaf still maintains some of its rigidity and color, it may recover after correcting the irrigation and improving the light.However, if it's completely soft, has changed color, or shows signs of rot, it's best to remove it as soon as possible.
