Forcing Rhubarb: A Guide on Inducing Rhubarb's Growth Acceleration
Ready to force some rhubarb for a delightful early harvest? Here's the lowdown on this delicious, winter- harvested treat.
First things first, it's essential to choose a well-established rhubarb plant (minimum 2-3 years old) for forcing. Avoid forcing the same plant annually, as it can weaken and potentially kill the plant. Instead, force once every 2–3 years to allow for recovery[1].
Now, let's time things right. Begin forcing in late December or early winter, after the plant has gone dormant. This timing encourages early stem growth before the normal spring season[4].
Cover the rhubarb crown with an upturned bucket, large pot, dustbin, or similar container, blocking out light completely. This encourages the rhubarb stems to grow longer, more tender, and paler, suitable for early harvest[1][4]. In cold regions or to speed things up, insulate the outside of the pot with a thick layer of straw or bubble wrap.
Don't forget to keep the soil evenly moist, especially during dry spells, as rhubarb is thirsty during warmer weather. Remove weeds and apply water consistently to promote healthy forced growth[1].
When the stalks reach a desirable length and thickness, harvest them gently, being careful not to damage the crown or roots[5].
To succeed with rhubarb forcing and harvesting, remember these tips:
- Do Not Force Annually: Forcing stresses the plant, so limit forcing to once every 2–3 years per plant[1].
- Fertilize in Spring and Summer: Enrich the soil with well-rotted manure or compost to provide nutrients for vigorous growth. Top up with fertilizer after the first harvest to sustain production[2][3].
- Water Regularly: Rhubarb requires consistent moisture, especially during forcing, to prevent growth inhibition[1][2].
- Remove Flowering Stalks: Cut off flower stalks as they appear to prevent energy diversion from stem production[1].
- Patience is Key: Avoid harvesting in the plant’s first year; allow the plant to establish its root system fully in early years for stronger future yields[2].
- Safety Note: Rhubarb leaves are poisonous and should not be eaten[1].
By following these steps and tips, you'll enjoy tender, early rhubarb stalks that provide a delicious harvest well before the growing season peaks. Happy forcing!
