What Is Rhubarb?
Rhubarb is a hardy perennial vegetable grown for its thick, colourful leaf stalks (stems). The leaves themselves are toxic and must never be eaten, but the stems are delicious when cooked.
Once planted, rhubarb returns every spring with minimal maintenance.
Best Rhubarb Varieties for the UK
Popular and reliable UK varieties include:
- Victoria – classic, heavy-cropping
- Timperley Early – early harvests
- Champagne – pink stems, excellent flavour
- Glaskins Perpetual – good for summer harvesting
Choose varieties based on harvest time and flavour preference.
Where to Grow Rhubarb
Rhubarb grows best in:
- Full sun or light shade
- Deep, fertile soil
- Free-draining ground
Avoid areas that become waterlogged in winter.
Rhubarb needs space—choose a permanent position where it won’t need moving often.
When to Plant Rhubarb in the UK
Best Planting Times
- Autumn: October–November (best overall)
- Early spring: February–March
Avoid planting during frozen or waterlogged conditions.
How to Plant Rhubarb (Step by Step)
Step 1: Prepare the Soil
- Dig deeply
- Remove weeds and stones
- Mix in plenty of compost or well-rotted manure
Good preparation now supports many years of growth.
Step 2: Plant the Crown
- Dig a hole large enough to spread roots
- Position crown so the buds sit just at soil level
- Firm soil gently around it
Do not plant too deep—this can cause poor growth.
Step 3: Water Well
- Water thoroughly after planting
- Keep soil moist while establishing
Spacing Rhubarb Plants Correctly
- Space plants 75–100cm apart
- Allow room for mature growth
- Avoid crowding
Rhubarb plants grow large and need airflow.
Growing Rhubarb in Pots (Is It Possible?)
Yes—but only with:
- Very large containers (40–50cm wide)
- Excellent drainage
- Regular feeding and watering
Pots dry out quickly and need more attention than ground-grown plants.
Watering Rhubarb
Rhubarb likes consistent moisture.
Watering tips:
- Water deeply during dry weather
- Mulch to retain moisture
- Avoid waterlogging
Dry conditions lead to thin stems.
Feeding Rhubarb for Big Harvests
Rhubarb is a heavy feeder.
Feeding Schedule
- Add compost or manure in autumn or winter
- Apply mulch in spring
- Liquid feed in summer if growth slows
Avoid high-nitrogen feeds late in the season.
Mulching Rhubarb (Very Important)
Mulch:
- Retains moisture
- Suppresses weeds
- Feeds the soil
Apply mulch around—but not directly over—the crown.
When Can You Harvest Rhubarb?
First Year
❌ Do not harvest
Allow the plant to establish.
Second Year
✔ Light harvesting only
Third Year Onwards
✔ Full harvesting allowed
Patience in the early years leads to much stronger plants.
How to Harvest Rhubarb Properly
- Pull stems gently from the base
- Twist and pull—don’t cut
- Harvest up to one-third of stems at a time
Never harvest after July to allow the plant to recharge.
Forcing Rhubarb (Optional)
Forcing gives early, tender stems.
- Cover crowns with a forcing pot or bucket in winter
- Harvest pale pink stems early spring
- Do not force the same plant two years in a row
Forcing weakens plants if overdone.
Common Rhubarb Problems
Thin Stems
- Poor soil
- Lack of feeding
- Overharvesting
Rotting Crowns
- Waterlogged soil
- Planting too deep
Flowering Stems
- Remove immediately
- Flowering reduces stem production
Dividing Rhubarb (Long-Term Care)
Divide every 5–7 years to:
- Rejuvenate plants
- Increase yield
- Create new plants
Best time: autumn or early spring.
Can Rhubarb Survive Frost?
Yes—rhubarb is extremely hardy.
- Tolerates heavy frost
- Dies back in winter
- Regrows vigorously in spring
One of the toughest UK crops.
Toxicity Warning (Important)
- Rhubarb leaves are poisonous
- Only eat the stems
- Remove leaves during harvest
Never compost large amounts of leaves where animals can access them.
Common Mistakes to Avoid
- Harvesting too soon
- Planting too deep
- Poor feeding
- Letting plants dry out
- Harvesting too late into summer
Avoid these and rhubarb becomes effortless.
Final Thoughts
Rhubarb is one of the most reliable crops you can grow in the UK. With the right planting position, rich soil, and a bit of patience in the early years, it will reward you with decades of heavy harvests.
Plant it once, look after it well, and rhubarb will quietly become one of the most productive and dependable plants in your garden.
