Rhubarb is a fruit-like vegetable that is enjoyed cooked and fresh. It is a member of the buckwheat family, and dates back to the 1700s in Europe.

Growing Rhubarb: A Gardener's Delight

Growing rhubarb is immensely rewarding. This perennial vegetable offers vibrant colors and flavors, perfect for pies and other culinary delights.

Choosing the Right Spot

Rhubarb loves sunlight. Ensure at least six hours of direct sunlight daily.

The soil should be well-draining and fertile. Enrich with organic compost for best results.

Pro tip: Sandy loam soils with a pH of 6.0 to 6.8 are ideal for rhubarb cultivation.

Planting Rhubarb

  • Plant rhubarb crowns in spring or fall.
  • Space them about 3 feet apart to allow room for growth.
  • Place crowns with buds facing upward. Cover with 2 to 3 inches of soil.

I learned the hard way that rhubarb prefers cooler climates – it struggles in extreme heat. If you're in a warmer region, choose a shaded spot.

Watering and Mulching

Rhubarb needs consistent moisture. Water deeply, especially during dry spells.

If the stalks look droopy, they likely need more water.

Apply mulch around the plants. This helps retain soil moisture and suppresses weeds.

Feeding and Care

Top dress with compost annually in early spring. Avoid over-fertilizing.

Rhubarb thrives with minimal fuss. Remove flower stalks to promote healthier foliage.

Harvesting Your Rhubarb

Wait until the second year to start harvesting. This ensures the plants are strong.

A well-established plant can produce for up to 10 years or more.

  • Harvest stalks when they are 12-18 inches long.
  • Twist and pull stalks, don't cut them.
  • Leave at least one-third of the stalks on the plant to allow regrowth.

Pests and Problems

Watch out for crown rot. Avoid by ensuring good drainage and not overwatering.

Rhubarb curculio beetles may attack, but they're usually not a major problem.

Remember: Rhubarb leaves are toxic. Always discard them safely.

Final Thoughts
