If your Gasteria ‘Little Warty’ appears unhealthy, it could be caused by 2 factors: Overwatering and pest infestation. Overwatering Letting your succulent sit in water for too long will lead to root rot. Overwatered soil prevents roots from absorbing the oxygen they need. Save your overwatered Gasteria ‘Little Warty’ by removing the diseased parts immediately. Gently remove your plant from the soil. Shake off excess soil and carefully examine the roots. Use a sharp sterile knife or shears to cut the rotten roots. Leave the plant on a strainer or mesh and allow the roots to dry out for two to three days. Replant your Gasteria ‘Little Warty’ in a terracotta pot filled with fresh potting mix. Water it properly. Pest Infestation Gasteria ‘Little Warty’ is prone to mealybugs and aphids infestation. As soon as you detect signs of pest infestation, give your plant immediate treatment. Remove mealybugs by directly applying a q-tip dipped in rubbing alcohol on them. You can also spray the plant with alcohol or diluted dishwashing soap. Repeat the treatment once a week until you rid the plant of mealybugs. Aphids can be removed by spraying your plant with soapy water or neem oil once a week until you get rid of the infestation. Dilute 1 tbsp of neem oil in 8 cups of water and mix well. When using neem oil, spray your plant in the late afternoon to prevent sun damage.
