Pruning rhubarb is not as easy as it seems.

When to Prune Rhubarb in Pennsylvania

BEST Time to Prune Fruits, Vegetables, Herbs, and Flower Plants!

There are three specific times you should prune your rhubarb plants:

  1. Early Season
  • When it is time to transplant your rhubarb plants into another pot or even your garden, simply prune 1 inch off the top of the plant down to its leaves. Repeat this for two to three of the largest stems.

2. Mid-Season

  • In the first 3 weeks that your rhubarb plants grow flowers you will want to prune them off. By pruning flowers off your rhubarb plants you encourage your plant to put its nutrients into its root system first. This will then allow your plant to have even more flowers and harvest.

3. Late Season

  • Finally, you want to prune your rhubarb plant throughout late summer to help promote a healthy plant and more harvest. In the late season, prune any dead leaves or stems any diseased harvest, and any suckers.
