After crocus blooms, allow the foliage to remain in the garden or lawn until it turns completely yellow. This allows the foliage to produce nutrients that sustain the bulb for the next growing season. Crocus bulbs grow best in dry soil, so don’t water plants after they bloom. Check out these rock garden design ideas!
Naturalizing Bulbs
Some crocus varieties thrive in the midst of a lawn, creating a carpet of color in early spring. Don’t shy away from planting the bulbs (also known as corms) under deciduous trees, beneath shrubs, or around the bases of perennial plants. The crocus will complete its life cycle before larger plants leaf out and limit its sunlight. Plus, trees offer growing conditions favorable to this plant beneath their canopies: drier soil and less grass than found in open areas of lawn. Crocus thrives in dry soil and areas with limited competition from grass. Delay mowing a lawn embedded with crocus until the plant’s foliage turns fully yellow. In some areas, this means delaying the first lawn mowing until mid- to late June. Give your plants the soil they deserve using these tips.
