This type of rhubarb seed was purchased from Forgotten Heirlooms. The variety is unknown and the stems stay green instead of turning red, but it makes a great cobbler and pie. These are first year seedlings so they will need a season before they can be lightly harvested. Rhubarb is a perrenial that lasts at least 5-10 years so plan accordingly!
Planting/Harvesting Notes
- Plant in very fertile, well drained soil
- Transplant two weeks before the last frost date in the early spring in soil that is amended with well rotted manure and plenty of compost.
- Be sure to plant in an area where pets cannot access the rhubarb. The leaves are toxic to humans and animals!
- Plants should be about 4 inches tall before transplanting.
- Choose a location protected from the heat or use tall annual plants, row covers, or a temporary shade structure to provide adequate shade.
- Do not allow the transplants to dry out in hot weather.
- Once your plant has 10 stalks, you can harvest 3-4 stems per plant. Havest the stalks ONLY. Do NOT eat the leaves. The leaves contain toxic levels of oxalic acid.
- Leave some stalks on the plant during the summer so the plant can store reserves in the roots over winter. It’s best to not harvest during the first year to allow the plant to build up stores in its roots.
- Harvest in the spring and fall only to allow the plant ample time to build up energy stores in the roots. Break off any flower stalks at ground level in the first year to ensure the plant puts all of its energy into its roots. The leaves will die back at first frost so you can harvest all stocks just before frost in the fall.
