Nope, you are not dreaming. We are seeing increased amounts of moss this spring because of the record amounts of moisture and the resulting wet conditions our area experienced in 2018, and continuing into 2019.
Moss propagates when grass is not growing during the late fall, winter and early spring. Common mosses need very little light and plenty of moisture. They flourish in shady, damp, poorly drained and acidic soil. While your lawn soil may have a good soil pH, that is only one factor.
Healthy lawn grasses need the opposite of moss growing conditions; therefore when conditions discourage grass growth, mosses seize the opportunity and spread into these areas. We have just experienced a cool, “wet” fall, winter and early spring resulting in prime moss growing conditions.
Dense shade also favors moss growth and leads to thinning of lawn grass. If the shade is from trees and shrubs, consider having them thinned to allow more light. There are chemical options for reducing moss; however, the long term solution is addressing the shade, soil compaction and drainage. One major item you cannot control is the amount of rainfall and the resulting damp soil conditions.
Moss becomes dormant during hot, dry times of the year, so as we move into spring and summer the areas of moss in your lawn should begin to diminish.
