Rhubarb is a quintessential addition to any British garden. With its vibrant red stalks and tart flavour, it’s a delight for both gardeners and food lovers. Whether you’re growing rhubarb for heartfelt crumbles, homemade chutneys, or refreshing summer drinks, this guide will cover everything you need to know—from planting to harvesting and even its health benefits.
Why Grow Rhubarb?
Rhubarb is a hardy perennial that thrives in the UK’s temperate climate. It’s easy to grow, incredibly resilient and, once established, will return year after year—offering you a reliable crop for decades. Even for novice gardeners, rhubarb is one of the most rewarding plants to cultivate.
When and How to Plant Rhubarb
Rhubarb is typically planted as crowns, which are dormant roots with buds. Here’s how to go about it:
When to Plant:
- Best Time: Autumn or early spring, when the ground isn’t frozen.
- Ideal Conditions: Rhubarb crowns prefer well-drained soil rich in organic matter like compost or well-rotted manure.
How to Plant:
- Choose the Right Location:
Rhubarb loves the sun, but it can tolerate partial shade. Make sure to pick a spot with ample space, as rhubarb plants can grow quite large.
- Prepare the Soil:
Loosen the soil and mix in compost or organic matter to improve drainage and fertility.
- Plant the Crowns:
Dig a hole deep enough to accommodate the crown, ensuring the buds are just about 2.5cm below the surface of the soil. Space multiple crowns at least 90cm apart to allow for growth.
- Water It Well:
After planting, water the crowns thoroughly to help them settle in and establish roots.
Tip:
Avoid harvesting any rhubarb in the first year after planting. This allows the plant to build up energy reserves for a strong foundation.
How to Care for and Look After Rhubarb
Rhubarb is relatively low-maintenance, but a little care goes a long way. Here’s how to keep your rhubarb thriving:
- Mulch Regularly:
Adding a layer of mulch around the base of the plant helps retain moisture, suppress weeds, and provide nutrients.
- Watering:
During dry spells, ensure consistent watering to prevent the plant from drying out.
- Remove Flower Stalks:
If flower stalks appear, remove them promptly to encourage energy to be directed toward the edible stalks.
- Divide Crowns:
Every 5–6 years, divide the crowns in autumn to revitalise the plant and prevent overcrowding.
When to Harvest Rhubarb
Harvesting rhubarb is one of the most rewarding steps. Timing is everything:
- When It’s Ready:
Rhubarb is typically ready for harvest between April and June. The stalks should be about 30cm long.
- How to Harvest:
Avoid cutting the stalks with a knife. Instead, hold the stalk at its base and gently pull or twist it away from the crown.
Important Reminder:
Never eat rhubarb leaves—they contain oxalic acid, which is toxic when consumed. Dispose of them in your compost bin instead.
Health Benefits of Rhubarb
Rhubarb is not only delicious but also packed with nutrients that offer numerous health benefits:
- Rich in Antioxidants:
Rhubarb is high in anthocyanins and other antioxidants that can help combat cell damage and reduce inflammation.
- Great for Digestion:
Rhubarb contains a good amount of fibre, which aids in digestion and promotes gut health.
- Low in Calories:
With only about 21 calories per 100g, rhubarb is an excellent choice for anyone looking to enjoy a healthy dessert.
- Boosts Heart Health:
Its potassium content can help maintain healthy blood pressure levels.
