How to Harvest Lamb's Quarters
Timing and technique make all the difference between tough, bitter greens and tender, mild wild spinach. Here's everything you need to know about harvesting and preserving lamb's quarters.
When to Harvest
The best harvesting window is early spring through early summer — before the plants begin flowering. During this period, the leaves are at their most tender, mildest in flavor, and highest in nutrition. Young plants under 12 inches tall provide the best quality.
- Spring (April–May): Prime time. Seedlings and young plants offer the most tender leaves.
- Early summer (June–July): Still excellent. Focus on growing tips, which remain tender even as the plant gets larger.
- Midsummer (July–August): Plants begin flowering. Harvest tips only; lower leaves get tough.
- Late summer/fall: Best for seed harvest rather than leaf harvest.
What to Harvest
- Growing tips (top 4–6 inches): The best part of the plant. These young, tender stem tips with attached leaves are ideal for any preparation.
- Young individual leaves: Strip young, bright green leaves from anywhere on the plant. Avoid yellow, wilted, or heavily damaged leaves.
- Avoid: Tough lower stems, yellowing leaves, leaves below knee height on mature plants, and leaves with significant insect damage.
Harvesting Technique
- Confirm the plant's identity: Check for the mealy white coating, diamond-shaped leaves, and other features described in our identification guide.
- Pinch or cut the tips: Use your thumb and forefinger to pinch off the top 4–6 inches, or use scissors/garden snips for a cleaner cut.
- Strip individual leaves: For larger plants, grip the stem and slide your hand downward to strip leaves.
- Take no more than 1/3: Leave enough of each plant for it to regrow. It will produce new side shoots from the cut points.
- Wash well: Rinse thoroughly in cold water to remove soil, insects, and the water-repellent mealy coating residue.
Post-Harvest Handling
Use fresh lamb's quarters within 3–5 days when stored properly: unwashed, loosely wrapped in a damp paper towel, inside a bag or container in the refrigerator. Wash just before use. Treat it exactly like you would fresh spinach.
Harvesting Seeds
For seed harvest, wait until late summer or early fall (August–September in most regions). Seeds are ready when they fall freely from the stalks when rubbed. Cut entire seed heads, dry further if needed, thresh, and winnow. See our seeds guide for detailed instructions.
Preserving Lamb's Quarters
Freezing
Best method — 6–12 months
Blanch 60 seconds, ice bath, squeeze dry, portion into freezer bags. The gold standard for long-term storage.
Drying / Dehydrating
6–12 months shelf-stable
Spread leaves on dehydrator trays at 110°F. 4–8 hours until crisp. Store in airtight containers. Crumble into soups or powder in blender.
Powder
Year-round nutrition boost
Dehydrate then blend to fine powder. Add 1–2 tsp to smoothies, soups, sauces, bread dough. Incredibly nutrient-dense.
Canning
Possible but not ideal
Treat like spinach: pressure canning only (NOT water bath). High water content makes it less suitable than freezing.

Frequently Asked Questions
Can you harvest lamb's quarters after it flowers?
Yes, but the quality changes. Once the plant flowers (typically July–September), the leaves become tougher, more fibrous, and develop a stronger flavor. They're still edible but less pleasant raw. Cooked preparations (soups, sautés) work best for post-flowering leaves. The seeds that develop after flowering are also edible and nutritious. For the best leaf quality, harvest before flowering.
How do you store fresh lamb's quarters?
Store fresh lamb's quarters like spinach: unwashed, loosely wrapped in a damp paper towel inside a plastic bag or container in the refrigerator. It keeps for 3–5 days. Wash just before use. For longer storage, blanch and freeze (keeps 6–12 months).
Can you freeze lamb's quarters?
Absolutely! Freezing is the best preservation method. Blanch leaves for 60 seconds in boiling water, immediately transfer to an ice bath, squeeze out excess water, portion into freezer bags or containers, and freeze. Properly frozen lamb's quarters keeps for 6–12 months and works great in cooked dishes (soups, sautés, smoothies).
