jut a quick follow up question, I have had this on mya rhubarb for years and it produces good rhubarb, am I safe to continue to eat the rhubarb. I have started a new rhubarb spot away from these but will not be ready for a couple of years. Can I continue to use it until my replacement rhubarb it ready.
Thank you so much for the answer and your help. Have a great day.
Unless the stems you harvest look or taste unusual, they should be safe to eat.
