This is the definition of a low maintenance plant. You can fertilize it a couple of times a year with a diluted general houseplant fertilizer. Sansevieria is okay with any humidity level. It is easily propagated by the division of root clumps and from leaf cuttings. It will grow pups and visibly outgrow its pot before it is necessary to re-pot this plant. The leaves can be wiped down every so often as they may collect some dust.
