Crocus Bulbs Information

Bearded Iris

One of the first signs of spring, Crocus bulbs (properly called corms) bloom extremely early in the spring, sometimes while snow is still present! These little jewels provide great bursts of color in partial shade to full sun areas, multiply readily and return year after year in zones 3 to 8. Crocus are very low maintenance and are great for rock gardens, naturalizing and planting in mass! They also are one of the easiest cold-hardy bulbs to force indoors!

Planting Crocus

  1. Crocus are typically planted in fall. Their roots will form in fall and they will bloom in early spring.
  2. It is critical to choose a planting location that has well drained soil and receives full to partial sun.
  3. Crocus corms should be spaced approximately 2-4" apart.
  4. Crocus corms should be planted with the flattest side down at a depth of 2-3". Sometimes it is difficult to determine the flat side of a corm; if unsure, take your best guess. It will not affect a bulb this small very much. Plant one corm per hole or plant several together to create a "bouquet" effect.
  5. Thoroughly soak the planting area with water once all of the corms have been planted. Water as needed while the plant is growing and blooming.
  6. Once the flowers have finished, allow the remaining foliage to yellow and die back. The leaves will continue to gather sunlight and make food for next year's blooms.
  7. Once the foliage has yellowed and dried, it may be removed by gently pulling it out of the soil. If the leaves do not easily pull away from the bulb, they are not ready to be removed. After the foliage has been removed, your crocus will be dormant and ready to "rest" until next year!
