10 Essential Terra Cotta Rhubarb Forcers for Garden Elegance and Early Harvests
Excluding light yields pale, tender stalks that add subtle sweetness to desserts.
In the world of kitchen gardens, terra cotta rhubarb forcers hold a unique place. These sculptural, functional cloches promise not only an earlier and more tender rhubarb harvest but also provide aesthetic valueâa marriage of practical gardening with timeless beauty. Though a standard fixture in English vegetable gardens, they have only recently started to capture the imagination of growers elsewhere.
What is a Rhubarb Forcer?
A rhubarb forcer is a bell- or chimney-shaped terra cotta pot, designed to cover the emerging shoots of rhubarb plants in early spring. By excluding light and trapping gentle warmth, the forcer coaxes the plant to produce long, pale, and exceptionally tender stems several weeks ahead of the usual harvest. These stems, called blanched rhubarb, boast not only a subtler flavor but also a reduced tartnessâcoveted by cooks for desserts and preserves.
Why Use Terra Cotta?
While glass and plastic options exist, terra cotta is preferred for its natural insulation, breathability, weight, and striking appearance. These forcers often become permanent residents of both historical and contemporary vegetable plots, forming centerpieces that look as good in winterâs bare beds as among lush summer foliage.
The Renaissance of the Rhubarb Forcer
The sudden renaissance of rhubarb forcers in the United Kingdom is a testament to their lasting appeal. As recently chronicled, the renewed interest can be traced in part to a serendipitous conversation between a noted potter and the Duke of Edinburgh at the Chelsea Flower Show. Inspired, designers and gardeners have revisited vintage shapes and revived old techniques, fueling a wave of new and classic styles now available.

How to Use a Terra Cotta Rhubarb Forcer
Deploying a rhubarb forcer is simple, yet benefits from attention to detail for best results. Here is a step-by-step overview:
- Start in Early Spring: As soon as rhubarb shoots begin to emerge, position the forcer over the plantâs crown.
- Fill with Straw or Mulch: To protect from late frosts and insulate the crown, some gardeners place a handful of straw inside.
- Lid On, Then Off: Keep the lid on initially. Once shoots elongate towards the light, remove the lid to prevent the growing stems from breaking the pot or forcing the lid off.
- Do Not Force Annually: Allow forced crowns a year to recover to maintain plant vigor; alternate forcing between established crowns when possible.
Key Design Features and Considerations
| Feature | Benefit | Notes |
|---|---|---|
| Removable Lid | Ease of access, air flow, and harvest | Improves usability for multiple crops |
| Hand-thrown Construction | Durability, unique visual appeal | Often more expensive |
| Frost Resistance | Year-round outdoor use, longevity | Essential for colder climates |
| Base Diameter | Fits over larger or mature crowns | Larger bases accommodate more established plants |
| Handles | Ease of placement and removal | More common in Cretan or continental designs |
| Vintage Patina | Authentic garden character | Increases collectible and decorative value |

Beyond Rhubarb: Additional Uses for Forcers
Though synonymous with rhubarb, these forcers work brilliantly to blanch and force other crops:
- Asparagus (extend the season and tenderize shoots)
- Chicory (produce heartier, less bitter leaves)
- Seakale (a rare gourmet vegetable)
This versatility contributes to their place as a staple of the serious kitchen garden.
Care, Placement, and Longevity Tips
- Soil Matters: Rich, well-rotted manure on the rhubarb bed improves yield and vigor after forcing. In poor soils, force only every other year.
- Cleaning: Gently wash with water and a brush at seasonâs end. Avoid harsh detergents that may linger in the clay.
- Overwintering: Store empty forcers upright in a frost-free shed if concerned about repeated severe freezes, but most are built to withstand British winters in the open garden.
- Display: When not in use, cluster forcers of varying shapes and sizes for instant sculptural impact in the garden border.
Frequently Asked Questions (FAQs)
Q: Can I use a terra cotta rhubarb forcer with other crops?
A: Yes. Besides rhubarb, these forcers can be used with seakale, chicory, and asparagus, all of which benefit from blanching and season extension.
Q: How often can I force the same rhubarb plant?
A: To maintain plant health, force each crown only every other year. Forcing every year can exhaust the plant and reduce future yields.
Q: What size forcer do I need?
A: For established crowns, choose a forcer with a 50-60 cm height and a generous base diameter (32-40 cm). For young plants, smaller options may suffice until they mature.
Q: Are antique or vintage forcers just decorative?
A: While many collectors value vintage forcers for their patina and aesthetics, properly preserved examples are perfectly functional and can be used like modern counterparts.
Q: What maintenance do terra cotta forcers require?
A: Rinse with water after use, inspect for cracks, and store carefully if your climate experiences extreme winter thaw-freeze cycles.
Where to Buy: Tips for Selecting Your Forcer
- Choose handmade, frost-resistant forcers from reputable potteries or garden suppliers to ensure years of reliable service.
- For decorative appeal, select a mix of heights and shapes (chimney, bell, Cretan-handled) for an evolving, attractive display.
- Check for removable lids, especially if you intend to use the forcer on a rotation of different crops throughout the year.
- Consider auctions or vintage dealers for rare or period pieces with unique history.
Conclusion: A Timeless Tool for Every Grower
