Winter dormancy is natural when it comes to most types of lawns. The grass you have in your yard has simply not evolved to grow and thrive under a certain temperature, so instead it will go into a state of dormancy that causes it to slow down its biological processes and avoid using too many resources. Water and nutrients will no longer be used up as much as during the spring, summer and autumn, and the result will be that your lawn will stop growing as well.
Just as the growth process stops well before the freeze sets in, it is also likely to start a little later than the end of winter, especially if the area you live in is a little more dry and cold. What happens is that the lawn is triggered by temperature growth, so when it gets warm enough, it will quit being dormant and resume its normal growth cycle.
During this period, you might notice the grass beginning to wake up slowly, as its color starts to turn a brighter shade of green, and it begins to grow. That’s basically your cue to start irrigating your lawn more frequently, as it will need water to sustain its growth properly. Later on (perhaps sometime around March to early April), when the weather is warm enough, you can also consider adding a suitable amount of organic, slow release fertilizer to help keep your lawn strong and robust.
