I am a new learner. I bought wheat grass for using in juices but I don’t know how to keep because I cannot use it all at one time. Should I keep in the refrigerator or outside? Also can I just cut the tips and if it keeps growing. Thanks in advance for educating me.

Wheat grass is the young shoots of wheat plants. If no instructions came with your wheatgrass, there is some information available on line (Google wheatgrass). It appears that once the grass has grown to its optimal level, you can keep it in the fridge for about a week. It seems that most people cut the grass only once.
