Rare and variegated houseplants require significantly less fertilizer than heavy-feeding garden crops or common fast-growing indoor species. Because variegated leaves contain less chlorophyll, these plants process nutrients at a slower metabolic rate. Over-application easily leads to mineral salt accumulation around delicate roots, resulting in tissue burn, leaf tip browning, or stunted growth. To keep rare plants healthy without risking fertilizer burn, dilute a balanced liquid fertilizer to one-quarter or one-half of the strength recommended on the product label and apply it only when the plant is actively growing under adequate light. ...
