Rhubarb, a vegetable often mistaken for a fruit due to its common use in sweet pies and tarts, is a staple in many gardens for its tart flavor and versatile uses. To enjoy rhubarb earlier in the season and to enhance its flavor and texture, gardeners often employ a technique known as forcing. This method involves using a rhubarb forcer, a tool designed to accelerate the growth of rhubarb stalks by simulating winter conditions and then providing a warm, dark environment that prompts early sprouting. In this article, we will delve into the world of rhubarb forcing, exploring what a rhubarb forcer does, its benefits, and how to effectively use one in your garden.
Understanding Rhubarb and Forcing
Before discussing the specifics of rhubarb forcers, it’s essential to understand the basics of rhubarb cultivation and the concept of forcing. Rhubarb is a perennial plant that typically grows from crowns planted in the ground. It requires a period of cold weather to break dormancy, after which it grows rapidly in the spring. Forcing involves manipulating the plant’s environment to coerce it into growing earlier than it naturally would, thereby extending the harvesting season.
The Science Behind Forcing Rhubarb
The process of forcing rhubarb is based on the plant’s natural response to environmental conditions. Rhubarb crowns need a certain amount of cold weather to induce them to grow. Once this cold period is satisfied, the crowns are ready to produce new stalks as soon as they are provided with the right conditions, such as warmth and moisture. A rhubarb forcer works by covering the crown and creating a warm, humid microclimate that encourages the stalks to grow. The darkness prevents the shoots from producing chlorophyll, resulting in tender, pale stalks with a sweeter and less bitter taste than those grown in full sunlight.
Benefits of Using a Rhubarb Forcer
Using a rhubarb forcer offers several benefits to gardeners and cooks alike. The primary advantage is the ability to harvest rhubarb up to 6 weeks earlier than usual, extending the rhubarb season and allowing for a longer period of enjoyment. Additionally, stalks produced through forcing are often milder in flavor and more tender in texture, making them ideal for a variety of culinary applications. Forcing can also help increase yields, as it allows for an earlier start to the harvesting season, potentially before pests and diseases become prevalent.
How to Use a Rhubarb Forcer
Using a rhubarb forcer is a straightforward process that requires some planning and attention to detail. Here are the general steps involved in forcing rhubarb:
A rhubarb forcer can be purchased or homemade. Traditional forcers are made of terracotta, but modern alternatives include plastic and wooden models. If you’re crafty, you can even create your own forcer using an old bucket or barrel, provided it has drainage holes to prevent waterlogging.
Preparing the Rhubarb Crown
Before applying the forcer, the rhubarb crown must be prepared. This involves removing any dead or rotting plant material from the crown to prevent disease and ensuring the soil around the crown is moist but not waterlogged. It’s also crucial to choose a healthy, mature crown for forcing, as younger crowns may not have the energy reserves necessary for early production.
Applying the Forcer
The forcer is placed over the prepared rhubarb crown, and the area around the base of the forcer is mulched to retain moisture and suppress weeds. The forcer should be covered with straw or another insulating material to regulate temperature and keep the environment warm and dark inside.
Monitoring and Maintenance
After applying the forcer, it’s essential to monitor the temperature and moisture levels inside the forcer. The ideal temperature for forcing rhubarb is between 40°F and 50°F (4°C and 10°C), and the environment should be consistently humid. Checking on the rhubarb regularly can help prevent overheating, which can lead to bolting (premature flowering), and ensure that the stalks are harvested at the optimal time.
Harvesting Forced Rhubarb
Forced rhubarb is typically ready to harvest within 6 to 8 weeks after applying the forcer. The stalks should be picked when they are between 10 and 12 inches long, as they become tougher and more bitter if left to grow longer. Harvesting is done by twisting the stalks at the base rather than cutting them, to avoid damaging the crown and compromising future yields.
Post-Harvest Care
After harvesting the forced rhubarb, it’s crucial to allow the crown to recover. This involves removing the forcer, exposing the crown to sunlight, and ensuring the soil remains well-watered but not waterlogged. The crown will produce new growth, but it may not be as vigorous as the forced stalks. It’s recommended to avoid forcing the same crown more than once every two years to prevent exhaustion and maintain the long-term health of the plant.
Conclusion
A rhubarb forcer is a valuable tool for any gardener looking to extend their rhubarb season and improve the quality of their harvest. By understanding how to use a rhubarb forcer effectively and taking proper care of the rhubarb crown, gardeners can enjoy an earlier and more bountiful rhubarb crop. Whether you’re a seasoned gardener or just starting out, incorporating a rhubarb forcer into your gardening practices can lead to a more rewarding and productive gardening experience.
For those interested in trying out forcing, it’s essential to start with healthy rhubarb crowns and follow the guidelines for preparation, application, and maintenance. With a little patience and the right techniques, you can unlock the full potential of your rhubarb plants and indulge in the unique, sweet-tart flavor of forced rhubarb earlier in the season than ever before.
What are Rhubarb Forcers and How Do They Work?
Rhubarb forcers are devices or structures used to accelerate the growth of rhubarb plants, allowing for an earlier harvest of the edible stalks. They work by creating a warm, dark environment that stimulates the plant to produce new growth. This is typically achieved by placing a container or cover over the rhubarb crown, which traps warmth and blocks out light. As the plant grows, it is forced to stretch upwards in search of light, resulting in longer, tender stalks that can be harvested before they become tough and fibrous.
The use of rhubarb forcers can significantly improve the quality and yield of rhubarb crops. By controlling the environment and providing optimal growing conditions, forcers enable gardeners to coax the best possible performance from their rhubarb plants. With proper care and attention, rhubarb forcers can produce stalks that are up to 2-3 weeks earlier than those grown without forcing. This not only extends the rhubarb season but also provides a head start on enjoying this delicious and versatile vegetable. Whether you’re a seasoned gardener or just starting out, using a rhubarb forcer can be a great way to get the most from your rhubarb plants.
