Preparing Rhubarb Crowns for November and Beyond
Rhubarb is a classic, low-maintenance perennial that rewards a little autumn care with extra-vigorous, sweet stalks in spring. November is the perfect month to look after established crowns, divide overgrown clumps, and set up for “forcing” an early harvest next year. Here’s exactly how to prepare your rhubarb patch for winter—and future bumper yields.

Why Prepare Rhubarb in November?
- Dormant period: As leaves yellow, rhubarb rests and is easy to work around.
- Strengthens crowns: A tidy-up and mulching now mean richer, plumper stalks.
- Disease and pest reduction: Removing debris cuts down on slugs and fungal problems.
- Time to divide: Mature crowns (5+ years) get reinvigorated when split in late autumn.
Step-by-Step: November Rhubarb Care
- Remove Old Leaves and Stalks
- Once frost blackens leaves, cut away and discard all foliage (don’t compost—often carries disease).
- Pull out soft, rotting stalks around the crown to avoid mold buildup.
- Weed and Tidy
- Gently weed around crowns, taking out grass and perennial intruders.
- Loosen the soil, but keep tools away from rhubarb buds just below the surface.
- Mulch for Winter Protection
- Spread a generous layer (5–10cm) of well-rotted compost, leaf mold, or manure around (not over) each crown.
- Mulch insulates roots, feeds crowns, and prevents weed growth.
- Divide Crowns (If Needed)
- If plants are crowded or tired, now is ideal for dividing.
- Lift the entire crown with a fork and carefully slice into chunks, each with at least one “bud” and healthy roots.
- Replant divisions straightaway at least 75cm apart; water well.
- Prepare for Forcing Rhubarb
- If you want super-early stems, mark your biggest, healthiest crowns now.
- In January/February, cover chosen crowns with a tall pot or forcing jar; stalks will grow in the dark, ready to pick by late winter.
Extra November Tips
- Avoid burying the crown itself with mulch—leave bud tips visible.
- Never harvest stems in winter—let crowns rest until spring.
- Tag new divisions for easy ID next season.
With a little November TLC, your rhubarb will emerge stronger, healthier, and more productive when spring returns—ready to kickstart the growing year with the first sweet, ruby-red stalks.
