What type of fertilizer for rhubarb?
+1
I've had the plants for 3 years, and they've never been fertilized! They are starting to grow, it's not too late, right? Something organic... I'm was just at a big box store, and read packages, but nothing about rhubarb. I bought some for our blueberries, would that work?

mix compost, rotted manure, or anything high in organic matter in the soil.Rhubarb plants are heavy feeders and need this organic matter. Don't add a chemical fertilizer when planting rhubarb or during the first year of growth. Direct contact with nitrates can kill your rhubarb plants- Good luck!!!
Here is a good source of information straight from growers. https://bonnieplants.com/growing/growing-rhubarb/
Horse manure works great.
Thank you, everyone!
