Forcing rhubarb is an ancient technique used to stimulate the early growth of this delicious and tart vegetable, allowing gardeners to enjoy its unique flavor and nutritional benefits months before its natural harvest time. But how long do you force rhubarb for, and what are the best practices to ensure a successful and bountiful crop? In this article, we’ll delve into the world of forced rhubarb, exploring the optimal duration, methods, and tips for achieving the perfect balance of flavor, texture, and yield.
Understanding the Basics of Forcing Rhubarb
Forcing rhubarb involves creating an environment that tricks the plant into believing it’s already spring, prompting it to produce its stalks prematurely. This is typically achieved by covering the plant with a container or a layer of straw and soil, which serves to exclude light, retain heat, and maintain moisture. By controlling these environmental factors, gardeners can manipulate the rhubarb plant’s natural growth cycle, encouraging it to produce tender, juicy stalks that are perfect for cooking and eating.
The Importance of Timing in Forcing Rhubarb
The duration of the forcing period is crucial, as it directly affects the quality and quantity of the rhubarb crop. If the forcing period is too short, the stalks may not have enough time to develop fully, resulting in a lower yield and less flavorful produce. On the other hand, if the forcing period is too long, the plant may become exhausted, leading to a decrease in its overall health and productivity. Generally, the forcing period for rhubarb can last anywhere from 6 to 12 weeks, depending on factors such as the variety of the plant, the climate, and the Desired level of sweetness and tenderness.
Factors Influencing Forcing Duration
Several factors can influence the optimal forcing duration for rhubarb, including:
The variety of the rhubarb plant: Some varieties, such as ‘Cherry’ and ‘Victoria’, are more suited to forcing than others, and may require shorter or longer forcing periods.
The climate: Rhubarb plants in colder climates may require longer forcing periods to produce the same level of growth as those in warmer climates.
The Desired level of sweetness and tenderness: Some gardeners may prefer their rhubarb to be more tart and crunchy, while others may prefer it sweeter and more tender. The forcing duration can be adjusted to achieve the desired level of sweetness and texture.
Techniques for Forcing Rhubarb
There are several techniques that can be used to force rhubarb, each with its own advantages and disadvantages. Some of the most common methods include:
Using a rhubarb forcer: A rhubarb forcer is a specialized container designed specifically for forcing rhubarb. It is typically made of terracotta or plastic and has a narrow neck and a wide base. The forcer is placed over the rhubarb plant, excluding light and retaining heat and moisture.
Using straw and soil: This method involves covering the rhubarb plant with a layer of straw and soil, which serves to exclude light and retain heat and moisture. This method is often less expensive than using a rhubarb forcer, but may require more maintenance.
Using a cold frame or greenhouse: A cold frame or greenhouse can provide the perfect environment for forcing rhubarb, offering protection from extreme temperatures and weather conditions. This method can be more expensive than the others, but can also be used to grow a wide range of other crops.

What is forcing rhubarb and why is it done?
Forcing rhubarb is a horticultural technique that involves manipulating the plant’s environment to stimulate early growth and production of tender, sweet stalks. This process typically involves covering the rhubarb plants with a container or structure that excludes light, which triggers the plant to produce new growth in search of light. By forcing rhubarb, gardeners can enjoy an early crop of rhubarb, often several weeks before the plants would naturally produce edible stalks.
The main reason for forcing rhubarb is to get a head start on the growing season and to produce a crop of high-quality stalks. Forced rhubarb is prized for its tender, sweet flavor and is often used in pies, jams, and other desserts. By controlling the environment and stimulating early growth, gardeners can produce a crop of rhubarb that is less bitter and more flavorful than naturally grown stalks. Additionally, forcing rhubarb can help to extend the harvest season, allowing gardeners to enjoy a longer period of fresh rhubarb production.
What are the ideal conditions for forcing rhubarb?
The ideal conditions for forcing rhubarb involve a combination of temperature, darkness, and moisture. Rhubarb plants typically require a period of cold temperatures to break dormancy, followed by a period of warm temperatures to stimulate growth. A temperature range of around 40-50°F (4-10°C) is ideal for forcing rhubarb, and the plants should be kept in darkness to stimulate the production of new growth. The soil should be kept consistently moist, but not waterlogged, to support the growth of the rhubarb.
In terms of specific techniques, gardeners can use a variety of methods to force rhubarb, including covering the plants with a terracotta forcer or a large pot. The rhubarb plants should be mulched with a thick layer of straw or compost to retain moisture and regulate soil temperature.
