Crocus are often called Snow Crocus because they will bloom when snow is still on the ground. There are over 80 species of this hardy perennial. Snow Crocus is one of the easiest spring flowers to grow and propagate.They require well-draining soils with a pH level between 6.0 and 7.0.
Things You Will Need
Plant Snow Crocus corms in a sunny to lightly shaded area. Because these earl spring flowers bloom before leaves are on trees, they can be planted close to them. Avoid planting corms within the tree's drip line.
Plant corms in soil that has good drainage and is slightly acidic. Soil that does not have good drainage or is heavy with clay can be amended by mixing organic matter into the top 12 - 18 inches of soil. The corms can be planted in raised beds or along hillsides to improve drainage.
Bone meal or superphosphate should be added to the soil below the corm to encourage root development in corms. In sandy soil, plant corms slightly deeper. Mulch around the Snow Crocus to preserve moisture.
Plant Snow Crocus corms in the fall 2 inches below surface. The corm's wider side should be on the bottom with the buds facing up. Water the corm thoroughly to prevent air pockets.Credit: wikimedia.org: by Der Wolf im Wald
Fertilize with 10-10-10 solution and avoid adding more nitrogen. Do not fertilize after they have started flowering.
Propagation occurs through the "mother" Snow Crocus producing several small corms before dying off. They multiply rapidly and corms should be dug up, separated and corms replanted every 2 - 3 years during the fall.
Corms can overwinter in the ground. Mulch over the winter, remove when the shoots begin to emerge in spring. Fertilize and water so you will be rewarded with healthy plants and more corms in fall.Credit: wikimedia.org: by Meneerke bloem
Tips & Warnings
Bulbs, corms and rhizomes that sit in too much water develop disease and/or rot quickly.
