Sow and Plant :Can be grown from seeds, but it is faster to grow from a dormant crown, or by cutting away and replanting a division taken from an established plant. Make new plantings or move old ones in spring.

Germination:  days

Spacing :Single Plants: 2′ 11″ (90cm) each way; Rows: 2′ 11″ (90cm) with 2′ 11″ (90cm) row gap

Feeding Use mulch to keep soil nutrient levels high. Mulch with rich compost in late winter, and add more mulch in summer to deter weeds and keep soil moist.

Harvesting :Use a sharp knife to cut new stems in spring as they reach 14 inches long. Discard leaves, which contain dangerously high levels of oxalic acid. Stop harvesting in early summer, and allow plants to grow freely the rest of the season.

Yield per 10ft of row: 12 lbs

Time to harvest: 365days

Troubleshooting :Trap slugs with beer, hand pick them in rainy weather, or spray them with caffeinated coffee first thing in the morning.

Notes : To make rhubarb stems longer, cover plants with bushel baskets or other large, breathable containers for one month in spring.
