Rhubarb is typically in season from early spring to early summer. Specifically:
- Field-grown rhubarb appears from late March to early April and is available through late spring to early summer. The season tends to slow down during the summer as rhubarb does not grow well in heat.
- Hothouse or greenhouse-grown rhubarb is available earlier, from late winter to early spring, before the outdoor crop.
- At farmers markets, rhubarb is generally found from April through June, with some cooler climates extending the season into summer.
- Harvesting usually stops around July to protect the plants.
In summary, the main rhubarb season is from late March/early April through June or slightly into early summer. After that, fresh rhubarb becomes scarce until the next season, though frozen rhubarb can be found year-round.
