How to Force Rhubarb Plants
Have you ever tasted sweet and tender rhubarb stalks? They are a delicious addition to any garden or kitchen. If you want to enjoy an early harvest, forcing rhubarb plants is the way to go. In this article, we will guide you through the step-by-step process of how to force rhubarb plants and get the most out of your garden.
What is Forced Rhubarb?
Forced rhubarb is the practice of growing rhubarb in complete darkness, which creates a unique pinkish color and a sweeter taste. When the rhubarb plant is deprived of light, it begins to break down its stored starches and convert them into glucose, resulting in a sweeter taste.
When to Force Rhubarb Plants?
The best time to force rhubarb plants is in late winter or early spring, around January or February. This will give you an early harvest of tender and sweet rhubarb stalks before the outdoor rhubarb plants have even started to grow. However, it is important to wait until the plant has experienced at least six weeks of cold weather (below 40°F) to ensure healthy growth and strong roots.
How to Force Rhubarb Plants Step-by-Step
Follow these simple steps to force rhubarb plants:
Step 1: Choose the Right Rhubarb Plant
Choose a healthy and established rhubarb plant that is at least two years old. This will ensure that the plant is strong enough to withstand the forced growth process. You should also pick a plant that is well-fertilized, with plenty of good quality compost and organic matter.
Step 2: Cut the Rhubarb Stalks
Cut the rhubarb stalks back to ground level, leaving only the crowns and a few inches of stem. This will allow the plant to focus its energy on producing new stalks instead of supporting old ones.
Step 3: Cover the Rhubarb Plant with Forcing Jars
Place forcing jars over the rhubarb crowns, making sure they are completely covered and sealed. This will create a dark and warm environment for the plant, which will stimulate growth and the development of sweet and tender rhubarb stalks.
Step 4: Water and Fertilize the Rhubarb Plant
Water the rhubarb plant regularly, but be careful not to overwater it. You should also fertilize it with a balanced fertilizer or organic compost to promote healthy growth and development.
Step 5: Harvest the Rhubarb Stalks
After about four to six weeks, the rhubarb stalks should be ready to harvest. Gently lift the forcing jar and cut the stalks as close to the base as possible. Remember to leave at least one-third of the stalks intact to ensure healthy regrowth.
Tips for Successful Forced Rhubarb
Here are some tips to help you achieve a successful forced rhubarb harvest:
- Make sure the rhubarb plant has experienced at least six weeks of cold weather before forcing it.
- Choose a healthy and established rhubarb plant that is at least two years old.
- Water and fertilize the rhubarb plant regularly to promote healthy growth.
- Use forcing jars to cover the rhubarb crowns and create a dark and warm environment.
- Harvest the rhubarb stalks as soon as they are ready to avoid overgrowth and loss of sweetness.
- Leave at least one-third of the stalks intact to ensure healthy regrowth.
Forcing rhubarb plants is a great way to enjoy an early harvest of sweet and tender rhubarb stalks. By following these simple steps, you can easily force your own rhubarb plant and enjoy its delicious taste in salads, pies, and jams. Remember to choose a healthy and established plant, cover it with forcing jars, water and fertilize it regularly, and harvest the stalks as soon as they are ready. Happy gardening!
