For how long can the wheatgrass be kept soiled after the 7th day?
You can keep wheatgrass in soil for an extended period, and its nutrition remains intact until it's in the soil. According to studies, the nutritional content reaches its peak around the 7th day of growth. However, this doesn't mean that the nutrition rapidly decreases afterward. In fact, you can maintain its nutritional quality in the soil for up to a maximum of 15 days. Beyond this time frame, you may notice the grass wilting or becoming pale in color, indicating a decline in its nutritional value. It's worth noting that once wheatgrass is cut, its nutritional content starts to diminish, with a noticeable decline occurring approximately 15 minutes after harvesting. Therefore, it's best to harvest and use wheatgrass when you need it to maximize its nutritional benefits
