Harvesting rhubarb at the right time is crucial to ensure you get the best flavor and texture from this unique vegetable. Understanding when to pick rhubarb involves knowing the plant’s growth cycle, seasonal changes, and how to select the perfect stalks. With a few simple guidelines, you can enjoy the vibrant tartness of rhubarb in various dishes.
This article guides you through determining when to harvest rhubarb, how to recognize optimal conditions for harvesting, and practical tips on storing and using it in your kitchen.
When To Harvest Rhubarb?
The best time to harvest rhubarb is typically in late spring to early summer, when the stalks are firm and vibrant in color. Generally, this period spans from April to June, depending on your climate and the variety of rhubarb you are growing. Look for stalks that are about 12 to 18 inches long and have reached their fullest color.
Understanding Rhubarb Growth Stages
Rhubarb goes through several growth stages during the growing season, and understanding these can help you determine the ideal time for harvesting.
1. Planting Year
If you are planting rhubarb from crowns, it’s essential to refrain from harvesting any stalks during the first year. Let the plant establish itself and grow strong. The following year, you can begin harvesting small amounts.
2. Early Growth
In the early growth stage, typically in late March or early April, rhubarb appears with tightly curled leaves and slender stalks. At this point, it is too soon to harvest. Allow the plant to continue growing and developing stronger stalks.
3. Peak Harvest Time
By late spring, your rhubarb will reach a height of 12 to 18 inches, and the stalks will have transitioned into a bright red or greenish hue, depending on the variety. This is the optimal time to begin harvesting, usually from April to June.
4. Late Season
As summer approaches, rhubarb may begin to bolt, indicated by the flowering stalks that shoot up. Once this happens, the flavor of the stalks becomes more bitter, and they become less desirable for culinary uses. It’s best to stop harvesting at this stage to allow the plant to direct its energy back into producing strong stalks for the next year.
Signs That Rhubarb Is Ready to Harvest
When deciding whether to harvest rhubarb, look for the following signs that indicate readiness:
- Color: Stalks should be vibrantly colored—usually a deep red or pink. However, green stalks are also mature, though they may not be as sweet.
- Length: Stalks should be at least 12 inches long for ideal flavor and texture.
- Firmness: The stalks should feel firm to the touch, not wilted or limp.
- Season: Harvest when nighttime temperatures are above 20°F (-6°C) and during the daylight hours when moisture levels are lower.
How to Harvest Rhubarb Properly
Harvesting rhubarb can be done efficiently and safely. Here’s how to do it:
- Gather Your Tools: You will need a sharp knife or garden scissors and a pair of gardening gloves to protect your hands.
- Choose Stalks Wisely: Select the outer stalks first, as this encourages the plant to continue producing more. Avoid taking more than one-third of the plant at any one time.
- Cutting Technique: Cut the stalks at the base rather than pulling them from the ground. Pulling can damage the root system, leading to weaker growth.
- Leave Leaves: Only the stalks are edible, while the leaves are toxic due to high oxalic acid content. Dispose of the leaves correctly.
Harvesting Tips and Techniques
To make the most of your rhubarb harvest, consider these practical tips:
- Timing: Harvest during dry weather, preferably in the morning, to minimize moisture on the plant, which can lead to bruising.
- Storage Method: Store harvested rhubarb in the refrigerator wrapped in a damp paper towel and placed in a perforated plastic bag. This keeps it fresh for up to a week.
- Regular Harvesting: Check your rhubarb plant every few days during the harvest season for new growth.
Storing and Using Rhubarb
Rhubarb can be used in various ways, from pies to sauces. Proper storage is essential to maintain its freshness.
Storage
Fresh rhubarb can last in the refrigerator for about a week. If you want to store it longer:
- Freezing: Clean and chop rhubarb into manageable pieces. Blanch for one minute in boiling water, then quickly cool in an ice bath. Drain well and pack in airtight containers or freezer bags. Frozen rhubarb can last up to a year.
