Rhubarb

rhubarb

Rhubarb is started by planting a division of a root from an older, healthy plant. Each root division should have a strong bud. Plant early in the spring in a well-drained area and place the root so that the bud is just below the soil surface.

Rhubarb should not be harvested the first year and should be harvested for only a few weeks the second year, but after that it can be harvested for 8 to 10 weeks. If seed stalks appear, cut them off.

When the rhubarb stalks become small and spindly start a new planting by dividing and planting roots from the old plants. If crown rot is a problem, use roots from disease-free plants and plant them in well-drained soil where rhubarb has not been grown.
