Dividing and Moving Rhubarb: Autumn and Early Spring Guide
Rhubarb is a long-lived, hardy perennial, but even the toughest plants benefit from being divided and moved every few years. Over time, crowns become crowded, yields decline, and stems get thinner. Dividing rhubarb rejuvenates the plant, improves harvests, and allows you to create new plants for other areas of the garden or allotment.
This guide explains when and how to divide and move rhubarb, focusing on the two best times—autumn and early spring—with clear, beginner-friendly steps and practical advice.

Why Divide and Move Rhubarb?
Dividing rhubarb has several benefits:
- Rejuvenates old, tired plants
- Produces thicker, stronger stems
- Prevents overcrowding
- Increases yields
- Creates free new plants
Most rhubarb plants benefit from division every 5–7 years.
Best Time to Divide and Move Rhubarb
🍂 Autumn (Best Overall Time)
When: October to November (after leaves die back)
Why autumn is ideal:
- Plant is dormant
- Less stress on roots
- Soil is still warm
- Strong root growth before winter
Autumn-divided rhubarb establishes well and grows strongly the following spring.
🌱 Early Spring (Second Best Option)
When: February to early March (before active growth starts)
Why spring works:
- Plant is still dormant
- Easy to see crown structure
- Good option if autumn was missed
⚠️ Avoid dividing once growth is well underway, as this weakens the plant.
When NOT to Divide Rhubarb
Do not divide rhubarb:
- In summer
- During active growth
- During very wet or frozen conditions
This causes stress and can reduce harvests for several years.
How to Lift Rhubarb Safely
- Cut back old leaves if still present
- Insert a fork well away from the crown
- Lift gently from several sides
- Raise the entire crown with as much root as possible
Large crowns can be extremely heavy—take your time.
How to Divide a Rhubarb Crown
Once lifted:
- Shake off excess soil
- Identify natural divisions in the crown
- Split using a spade, knife, or saw
- Ensure each division has:
- At least 1–3 healthy buds
- A good section of root
Discard any old, rotten, or weak central pieces.

How Many New Plants Can You Get?
A healthy crown can usually be divided into:
- 3–6 strong new plants
Very old plants may produce even more divisions.
Preparing the New Planting Area
Rhubarb is a hungry plant and stays in the same spot for years.
Soil Preparation
- Choose a sunny or lightly shaded spot
- Dig deeply and remove weeds
- Add plenty of compost or manure
- Improve drainage if soil is heavy
Good preparation now pays off for years.
How to Replant Rhubarb Divisions
- Dig a hole large enough for roots to spread
- Place crown so buds sit just at soil level
- Firm soil gently around roots
- Water thoroughly
Spacing:
- 75–100cm between plants
- Allow room for mature growth
Aftercare for Divided Rhubarb
Watering
- Water well after planting
- Keep soil moist but not waterlogged
Mulching
- Apply mulch around (not over) the crown
- Helps suppress weeds and retain moisture
Feeding
- Avoid strong feeds immediately
- Compost or manure is usually enough
Can You Harvest After Dividing?
- Autumn-divided plants: Do not harvest the following spring
- Spring-divided plants: Avoid harvesting for the first season
This allows roots to re-establish and prevents weakening.
How Long Until Full Harvests Return?
- Light harvests: Year 2
- Full harvests: Year 3
Patience leads to thicker, stronger stems long-term.
Common Mistakes to Avoid
- Dividing too often
- Planting crowns too deep
- Harvesting too soon
- Poor soil preparation
- Letting new plants dry out
Avoiding these mistakes ensures long-lived plants.
Can You Move Rhubarb Without Dividing?
Yes—but division is strongly recommended.
Moving without dividing:
- Doesn’t rejuvenate the plant
- Often results in poor growth
- Misses the opportunity for new plants
If you’re lifting it, it’s best to divide it too.
Signs Rhubarb Needs Dividing
- Thin stems
- Reduced harvests
- Crowded crowns
- Weak growth
- Poor vigour
These are clear signals it’s time to act.
Final Thoughts
Dividing and moving rhubarb is one of the best things you can do for long-term productivity. Autumn is the ideal time, with early spring as a reliable alternative if needed. With careful lifting, clean division, and good soil preparation, you’ll rejuvenate old plants and enjoy stronger harvests for many years to come.
Once done properly, rhubarb will reward you with decades of reliable cropping—making this a job well worth doing.
