If you’re growing rhubarb, knowing when to harvest it makes a big difference in flavor and texture.
Pick it too early, and the stalks are small. Too late, and they can become tough and stringy.
The best time to harvest rhubarb is in late spring through early summer, when the stalks are firm, thick, and full of flavor.

When to Harvest Rhubarb
Rhubarb is usually ready to harvest from April through June, depending on your climate.
The best harvest window is when:
- Stalks are 10–15 inches long
- Stalks are thick and firm
- Color is rich (red or green depending on variety)
Harvesting during this time gives you the best flavor and texture.
How to Tell When Rhubarb Is Ready
Instead of focusing only on timing, look at the plant itself.
Your rhubarb is ready when:
- Stalks are full-sized and sturdy
- Leaves are fully open
- The plant looks healthy and established
Avoid harvesting:
- Thin, weak stalks
- Very young plants
How to Harvest Rhubarb
Harvesting rhubarb is simple and quick.
- Grasp the stalk near the base
- Gently pull and twist
- The stalk should snap cleanly
You can also use a knife, but pulling helps prevent damage to the plant.
Always remove the leaves and discard them—they are not safe to eat.
When to Stop Harvesting
It’s important not to harvest for too long.
- Stop harvesting by mid to late summer
- Leave some stalks so the plant can recover
- Avoid harvesting in the first year
This helps your plant stay strong for next season.
How to Store Rhubarb
After harvesting:
- Remove leaves right away
- Rinse and dry the stalks
- Store in the refrigerator (up to 1 week)
For longer storage:
- Cut into pieces
- Freeze in airtight bags
Rhubarb freezes very well and keeps its flavor.
