LOSING ITS COLOUR
At different times of year and in different weather conditions, grass can appear different shades of green. Grass grows at different rates based on its location, type or the weather. In spring, it is likely to grow most rapidly, producing new cells such as chloroplasts. The higher the concentration of chloroplasts within a blade of grass, the more green pigment there will be too. When grass turns brown or yellow it might still be alive, but very low on chlorophyll.
If you notice that the bottom of the blades of grass are losing their green colour, this is often due to the amount of water the grass is getting. When grass becomes dry, the lower parts of the blades will begin to turn brown, but if the opposite is true and you are overwatering the grass, it may appear yellow. This is because if the soil is waterlogged, oxygen can’t get to the plant and the grass becomes oxygen-deprived.
