An aloe plant that is slowly softening is a sign of overwatering. The aloe vera leaf contains soft translucent gel making it thick. If you remove a leaf and peel, it off, you can use extract the gel naturally and apply it to your hair. This moistness is the reason why the aloe plant cannot take in more water. Excessive hydration can lead to softening of the leaf. Without immediate intervention, your plant can succumb to the excess water. If your aloe plant, expose your plant under indirect sunlight. This helps dry the excess water and normalize the soil. Aloe vera requires dry soil to thrive successfully.
