Rhubarb Problem

Asked January 23, 2018, 10:07 AM EST

Hello! We have rhubarb planted in our front yard (we live on the sand planes in Ramsey) and every year it gets something that causes spots, makes the leaves turn yellow, then brown, then die. My rhubarb has been planted now for four years and hasn't spread or thrived due to this fungus or whatever it is. Any ideas what it is and how to take care of it organically? Thank you! Nikki

I believe your rhubarb is unhappy in the area where it is planted. It is a heavy feeder. It needs full sun and soil that has been amended with good compost. It also needs to be fertilized each year. If it is just in our Anoka County Sand Plain soil without amendments, it will not thrive. You can try moving it to a suitable amended site. Maybe just half the roots this year and then try fertilizing the remaining portion this spring. Also, all old leaves need to be cleaned up and fresh soil/compost worked in gently around the roots. It is possible you have a fungus and, if so, dispose of what you have and plant a fresh plant in a suitable spot.
