Rhubarb, with its tart yet sweet flavor, is a beloved ingredient for pies, crumbles, and jams. But what if you don’t have a sprawling garden? You can still enjoy fresh, homegrown rhubarb by learning how to grow rhubarb in a pot. Growing rhubarb in containers opens up a world of possibilities for even the smallest urban gardens or balconies.
Why Grow Rhubarb in a Pot?
Growing rhubarb in a pot offers several advantages:
- Space-Saving: Perfect for limited garden space, balconies, or patios.
- Control: You have more control over the soil, water, and nutrients.
- Mobility: Move your rhubarb pot to different locations for optimal sunlight.
- Pest Control: Easier to manage pests and diseases in a contained environment.
Choosing the Right Pot and Soil
The first step to growing rhubarb in a pot is to select the right container and soil.
- Pot Size: Choose a pot that’s at least 18 inches wide and 18 inches deep. Rhubarb plants have deep roots and need ample space to thrive.
- Material: Terracotta pots are ideal as they allow for good drainage. However, plastic pots are also suitable, especially in colder climates.
- Drainage Holes: Ensure the pot has drainage holes to prevent waterlogging.
- Soil: Rhubarb prefers rich, well-draining soil. Use a good quality potting mix or amend your garden soil with compost and peat moss.
Selecting and Planting Rhubarb Crowns
Rhubarb is grown from crowns, which are the underground stems.
- Choose Healthy Crowns: Look for crowns that are firm, plump, and free of disease.
- Planting Time: Plant rhubarb crowns in early spring or late fall.
- Planting Depth: Plant the crowns about 2 inches deep, with the buds facing upwards. Space multiple crowns 18-24 inches apart.
Providing the Right Conditions for Rhubarb Growth
Rhubarb thrives in full sun to partial shade, receiving at least 6 hours of sunlight per day.
- Sunlight: Choose a sunny spot for your pot, but avoid scorching afternoon sun, especially in hot climates.
- Watering: Keep the soil consistently moist, but not waterlogged. Water deeply and allow the top inch of soil to dry out between waterings.
- Fertilizing: Feed your rhubarb plants with a balanced fertilizer every 4-6 weeks during the growing season.
Harvesting Rhubarb
- First Harvest: Wait for at least two years after planting before harvesting any stalks. This allows the plant to establish itself.
- Harvesting Time: Harvest rhubarb stalks in early spring, before the plant flowers.
- Harvesting Technique: Cut the stalks at the base with a sharp knife, leaving at least 2 inches of stalk above the ground.
Protecting Your Rhubarb Plant
- Winter Protection: In colder climates, protect your rhubarb plant from frost by covering the pot with a thick layer of mulch or burlap.
- Pest and Disease Control: Monitor your rhubarb plant for pests like aphids and slugs. Treat any infestations promptly.
Rhubarb Plant Care: Beyond the Basics
- Dividing Rhubarb: To rejuvenate your rhubarb plant, divide the crowns every 3-4 years.
- Mulching: A layer of mulch around the base of the plant helps retain moisture and suppress weeds.
- Rotation: Rotate your rhubarb pot every year to prevent nutrient depletion.
A Final Flourish: Enjoying Your Homegrown Rhubarb
Now that you have a thriving rhubarb plant, it’s time to reap the rewards of your labor! Use your homegrown rhubarb to create delicious pies, crumbles, jams, and even cocktails. Experiment with different recipes and enjoy the sweet-tart flavor of your own garden bounty.
A Farewell to Rhubarb: The End of the Season
As summer approaches, your rhubarb plant will start to slow down its growth. This is a natural cycle, and your plant will go dormant for the winter months.
- Prepare for Dormancy: In late summer, stop fertilizing and reduce watering.
- Winter Protection: Ensure your rhubarb plant is adequately protected from frost.
