Shamrock Spider Plant Care. Shamrock plants attract aphids, whiteflies, and spider mites. Water regularly and thoroughly while actively growing, but shamrocks prefer to be kept on the dry side during winter while they are dormant.

If this happens, stop watering and fertilizing and store pots in a cool, dark location until new growth begins to show. Fertilize shamrock lightly once every month while the plant is actively growing, then withhold fertilizer when the plant enters dormancy. You will need to repot this plant soon, since the nursery gives you just a small container to start.
