Phaulothamnus are relatively rare and understudied, and detailed care requirements are not widely documented. However, like many plants, they are likely to thrive with attention to light, water, soil type, and temperature conditions that mimic their native habitats. Gardeners should be vigilant for signs of pests or diseases, though specific challenges to phaulothamnus are not well-established. Seasonally, phaulothamnus may have different needs regarding water and protection from temperature extremes, requiring adjustments to care practices as temperatures fluctuate throughout the year.
