My Grass Looks Dead After Winter: 8 Steps to Restore Grass

Winter season is a time when almost all living things hibernate. This is the season when our survival instincts would tell us to store and preserve as much heat and energy to fight the cold. We observe this phenomenon among animals and even humans. But do you know that plants also hibernate?

Plants go through a dormancy phase where they save up their nutrients in their roots to survive through the coming harsh weather conditions. According to a study published in Annals of Botany, this applies to both summer and winter seasons. Plant dormancy also shares the same characteristics during both seasons: there is the browning of their blades while its crown (tip) remains green.

Unlike animals and humans who can move around and hibernate themselves to safety, plant obviously can’t. So, dormancy is their best way to protect themselves.

Why Does My Grass Look Dead After Winter?

One reason grass looks dead after winter is dormancy. By the end of winter, your grass is still trying to recover from it and in a short few days, you will see how your lawn will start to look greener again. Of course, that should be aided with lawn care such as clearing, watering, and fertilizing appropriately.

However, another more concerning reason is winter stress. The effects of winter stress are varied depending on the type of grass. But one common effect of it is that your lawn starts to look brown or dead after the winter.

Sudesh Kumar Yadav wrote a review on ‘Cold Tolerance Mechanisms in Plants’ and noted that a plant’s cold tolerance (including grasses) depends on its sensitivity. Thus, its physical characteristics in the effect of the winter season also vary. This includes chlorosis (yellowing or browning), wilting, reduced expansion, and necrosis or death.

The extreme cold weather can also stunt the growth of the plant. Like dormancy, the winter stress can stop the grass from growing lush and green. Thus, it would look dead after the winter.

This can also be because it is in the plant’s nature to adapt to its external factors like the weather. One of the affected systems of plants during the winter is their reproductive development. Cold stress delays its growth and its ability to reproduce. This would explain why your grass won’t be as healthy as it usually is in the warmer season.

But the most adverse effect of cold stress in plants is the damage on its plasma membrane.

The plasma membrane contains saturated and unsaturated fatty acids. The ratio between these two determines a plant’s transition temperature. The plants that have more saturated fat have a higher transition temperature, this makes them more sensitive to cold temperatures.

That is why it is essential to know which grass species are more resistant to cold so you can plant them on your lawn rather than planting those that are sensitive to cold temperatures.

What Kind of Grass Turns Brown in the Winter?

Like most plants, some grass species are also seasonal. If you plant a warm-season grass species, they are the kind of grass that would be more likely to turn brown in the winter.

As the name suggests, warm-season grasses thrive in warmer climates and can withstand drought. However, they mostly go partially or completely dormant during the winter turning into brown during this season.

Two of the most common warm-season grasses are St. Augustine and Bermuda grasses. Zoysia is a popular one, too. However, the two mentioned earlier grow faster than Zoysia.

The Bermuda grass also tends to survive the winter season more, especially the hybrid ones. St. Augustine, on the other hand, is tough and can withstand drought but would look shabby during the winter.

Other warm-season grasses that turn brown during the winter are Bahia Grass and Centipede Grass.
