Glaskin's Perpetual Rhubarb Seeds

Product Details

This English heirloom variety was bred for early maturity and a long harvest window. Glaskin's Perpetual Rhubarb is tart, but never bitter due to its naturally low oxalic acid content. If it's given a good early start indoors, it can be harvested (late) during the first season's growth. Some leaves should be left unharvested to encourage good root growth and a strong return the following summer. The thick, succulent stems grow 30-35cm (12-14") long, with a primarily pink and green pigment and some red markings. This is the best rhubarb variety for harvesting later in the year. Grow it in full sun, in rich, fertile, well drained soil.

Matures in the first year. (Open-pollinated seeds)

Timing

Timing
Sow indoors in early spring and transplant or direct sow about 8 weeks after the last frost date where plants are to grow permanently. Optimal soil temperature: 16-25°C (60-75°F). Seeds should sprout in 5-10 days.

Starting

Starting
Sow 2cm (1″) deep, but plan for large plants. One plant will typically satisfy the needs of one household. Farm rows 100-120cm (36-48″) apart, plants 120 (48″) apart in the row.

Growing

Growing
Ideal pH: 6.0-6.8. Any well-drained, moderately fertile garden soil will do. Mulch around plants in fall with finished compost or well rotted steer manure. Choose a sunny spot. Rhubarb is cold hardy and drought tolerant. After growth stops in the fall, the plants go dormant, and require a period below 4°C (40°F) to stimulate good spring bud growth. In the second year, remove flower stalks as they appear. Divide plants every 4-5 years. A well maintained plant should produce for over a decade.

Harvest

Harvest
Do not harvest during the first year of growth. Cut the tart red stalks in spring after the first year of undisturbed growth. Do not eat the leaves. Stalks can be harvested all at once or selectively as required.

Seed Info
