Care for a crocus plant by watering it during dry spells during the fall and covering it with a 2- to 4-inch layer of mulch before winter. The low-maintenance plant is a perennial that blooms in early spring and multiples regularly.
Apply a balanced fertilizer on established plants in early autumn. In late winter, remove the layer of mulch to allow any shoots access to the sun.
Do not provide excessive water to crocus plants as the roots of the plant are susceptible to rot. Should the threat of severe weather occur, cover any crocus plants with a bottomless gallon milk jug.
Add a crocus plant to your landscape by planting crocus corms -- the vegetative organ from which the plant grows -- 4 inches deep in a hole that has been tilled about 12 inches deep. Place the corm pointed end skyward and backfill with a mixture of the tilled soil and compost. Space plantings 3 to 4 inches apart. Almanac.com recommends planting crocus in clusters for an aesthetically pleasing effect. Planting bulbs inside a metal cage can prevent moles or voles from eating the corms.
The crocus plant comes in many colors, including blue, violet, yellow and white. An average crocus grows to a height of 3 to 6 inches and features cup-like blooms. The species is grown in agricultural zones three through eight.
