For gardeners eager to enjoy fresh rhubarb before the traditional spring harvest, forcing rhubarb in March offers an exciting opportunity. This method accelerates growth by mimicking early spring conditions, allowing you to harvest tender stalks months ahead of the usual season.
Understanding Rhubarb Forcing
Rhubarb is a hardy perennial that naturally emerges in early spring. Forcing involves creating a warm, dark environment that tricks the plant into thinking winter has ended, stimulating early growth. This technique is especially popular in colder climates where the ground remains frozen for much of the year.
Preparing Your Rhubarb for Forcing
To successfully force rhubarb, start with healthy, established plants. The best time to begin is in late winter, around February or early March, depending on your climate. Select thick, vigorous stalks and ensure your plants have been well-watered and fertilized in the previous season.
Choosing the Right Plant
Look for crowns that are at least two years old. Avoid plants that show signs of disease or weakness. Healthy plants produce robust stalks suitable for forcing.
Forcing Rhubarb: Step-by-Step Guide
- Prepare the bed by removing weeds and adding compost to enrich the soil.
- Cut back the stalks to encourage new growth and remove any damaged leaves.
- Cover the crown with a large, dark container or a specially designed forcing jar to block out light.
- Ensure the cover is secure and airtight to maintain darkness and warmth.
- Maintain consistent moisture and temperature; ideal conditions are around 60-70°F (15-21°C).
- Check regularly for signs of growth, which should appear within a few weeks.
Care and Harvesting
Once the stalks emerge, continue to keep the environment dark and warm. Harvest the rhubarb by cutting the stalks at the base once they reach about 8-12 inches tall. Be gentle to avoid damaging the plant.
Remember, forcing rhubarb can weaken the plant if done repeatedly. Allow the plant to rest after forcing by removing the cover and letting it recover for the rest of the season.
Tips for Successful Forcing
- Use a dark cover that fits snugly to prevent light infiltration.
- Maintain consistent watering to keep the soil moist but not waterlogged.
- Apply a balanced fertilizer before forcing to promote healthy growth.
- Avoid disturbing the plant once it has been covered.
- Monitor for pests and diseases during the forcing period.
Conclusion
Forcing rhubarb in March is a rewarding gardening technique that allows you to enjoy fresh, tender stalks early in the season. With proper preparation and care, you can extend your harvest and impress your friends with homegrown produce even before the traditional harvest time.
