Rhubarb Planting Instructions
Rhubarb crowns have to be planted shallow. At least 1/4 to 1/3 of the crown surface should be above ground level when properly planted. If the bud itself is below the soil line it may rot off and fail to grow. We have seen fall planted crowns frost heave and roll around on the soil surface and still grow! This isn’t an ideal situation, but it makes the point that a shallow crown will often grow and a crown planted below the surface almost certainly wont.
