Likely causes

    Most likely

    How to tell: The soil feels constantly wet or swampy. The base of the plant may look mushy or discolored.

    What to do: Stop watering immediately and allow the top inch of soil to dry out. Ensure the pot has excellent drainage and never let it sit in a saucer of water.

  2. Insufficient Light

    Possible

    How to tell: The grass looks pale and yellow, especially on the lower leaves. It may also appear stretched out.

    What to do: Move the plant to a spot that receives full, direct sun. Sweet vernal grass needs plenty of light to maintain its healthy color.

Questions people ask

Can yellow leaves turn green again?
Usually, no. Once a leaf turns yellow, it will likely stay that way or eventually die, so focus on preventing new yellow leaves.
Is my plant getting too much sun?
Sweet vernal grass loves full sun, so it is rarely too much. If it is yellowing, it is almost certainly a water or light deficiency.
