This tart, easy-to-grow perennial is great for pies and jams, especially when coupled with strawberries. It comes to life when temperatures rise into the 40s F, making it one of the earliest spring crops.

Growing Guide
GROWING NOTES
Yields best in full sun.

Well-drained, deep, fertile soil, high in organic matter, pH 5.5 to 6.5. Yields best with plentiful, consistent moisture.

Needs extended temperatures below 40 F.

Flower stalks may reach 5 feet tall.

Remove flower stalks to increase production.

MAINTAINING
Carefully consider location before planting this long-lived perennial. If possible, establish planting area and improve soil the season before planting.

Plant dormant crowns, as soon as you can work the soil in spring. You can cut crowns into pieces, but make sure each has at least one strong bud. Plant 1 to 3 inches deep and 2 to 3 feet apart.

Mulch to suppress weeds and retain moisture. Plants require little or no fertilizer.

Remove flower stalks as they appear the first year to give strength to developing plant. Do not harvest any leaf stems until plants are well-established the second year. Removing flower stalks helps plants channel energy into leaf stem production.

Growth slows and flower stalks form when temperatures warm in summer. In cool regions, growth may continue if you have adequate moisture and remove flower stalks. In warmer areas, growth may resume in fall - sometimes enough for a light harvest.

Horseradish makes a good companion crop, as both are long-lived perennials.

Renovate beds when plants become crowded and leaf stems small (usually in 5 to 15 years) by dividing crowns and replanting in fall or spring.

To force rhubarb in winter: Dig plant in autumn after dormancy but before the soil freezes. Pot with buds 1 inch below soil surface and keep outside for at least 8 weeks with temperature below 40 F. Move pot inside to cool, dark location. Keep soil moist, and rhubarb should be ready to harvest in about 6 weeks. (Stalks will be well-developed, but leaves will be small and yellow.) Replant outside in spring.
