Celosia are considered to be low-maintenance plants, but can encounter aphids, spider mite or fungal diseases in wet environments. Root rot or discoloration of leaves can be occasioned by poor drainage and overwatering. Look after plants by checking them frequently to detect any pests and treat the infestation at an early stage using insecticidal soap or neem oil. Spacing, good air circulation and sanitation of gardening equipment will aid in avoiding disease and ensure that celosia plants are kept healthy and colored.
