Haworthia Limifolia “Spider White” White Fairy Washboard is not considered a difficult houseplant to grow—if you can keep a pot of aloe alive on a windowsill, chances are you can do the same with Haworthia Limifolia. As with all succulents, the most dangerous situation is too much water, since they should never be allowed to sit in water under any circumstances. If you’re given a Haworthia Limifolia in such a container, make sure the container had adequate drainage
Watering
Water once a week or when the soil starts to become slightly dry at the top. Keep the soil lightly moist at all times, but do not overwater as this will cause brown spots and leaf drop. Curly or dry leaves suggest, the plant is dry and needs watering. Water in the early morning or late evening when temperatures are cooler. Always check your soil before watering.
