How to Transplant Potted Crocus

Crocuses require replanting every three to four years because new bulbs, or corms, grow on top of the old ones each year. Crocuses grow best in rich, well-draining soil in full sun to light shade in USDA Plant Hardiness Zones 3 through 8. Whether you're transplanting crocus corms from one pot to another pot, or to your flowerbed, they require a cool, dark resting place for 12 to 13 weeks at about 35 to 45 degrees Fahrenheit after the transplanting. Transplant crocus corms in the late summer or early fall after the leaves die back and the plant goes dormant.

Trimming shears
Well-draining soil
Pot (optional)
Water-soluble fertilizer

Instructions

- 1
  Use a small gardening fork to gently work the crocus corms up out of the soil without damaging the corms.
- 2
  Separate the clumps of corms into single corms, and dispose of any that are damaged or rotting.
- 3
  Trim any dead leaves from the bulbs.
- 4
  Fill the new pot or pots with soil, or work the soil into a flowerbed.
- 5
  Dig holes three to four inches deep and three to four inches apart, then place one crocus corm in each hole with the roots down, and cover it with soil.
- 6
  Water the newly planted crocuses thoroughly right after planting, then allow the soil to dry before watering lightly as needed. Crocuses require light watering in the spring and fall, but not during the summer or winter when they are dormant.
- 7
  Place the crocuses in pots in a cool, dry area for about 12 to 13 weeks during the winter. Move them indoors to a warmer, lightly sunny area where the temperature is about 50 to 60 degrees Fahrenheit once they begin to sprout. While they are flowering, provide at least four to six hours of sun per day.
- 8
  Allow the crocuses to wilt and dry naturally after they are done blooming so the corms are well-nourished in preparation for their summer dormancy.
