Spring crocus is a low-maintenance bulb that thrives when planted in well-draining soil in autumn for a cheerful early-spring display. Water regularly during active growth but let the soil dry out once foliage has died back in summer. Plant corms about 3 inches deep and enjoy minimal ongoing care year after year.
