Growing Asparagus from Seed: Those Red Berries Are Your Future Crop

If your asparagus plants are sporting bright red berries, you're looking at the next generation. Those berries contain seeds—and with a little patience, you can grow an entirely new asparagus bed for a fraction of the cost of crowns.

Harvesting and Storing Asparagus Seed

1. Collect berries as they turn fully red in autumn
2. Spread on paper towels indoors to dry completely (1–2 weeks)
3. Rub dried berries between palms to separate seeds from pulp
4. Store seeds in a cool, dry place until late April

Planting for Success

Wait until soil is thoroughly warm (late April in most regions). Sow seeds 1 inch deep and 4 inches apart in a sunny, well-prepared nursery bed. Seedlings emerge by June. Let them grow undisturbed through their first season—no harvesting! In October, transplant the strongest plants to their permanent bed.

The Patience Payoff

Seed-grown asparagus takes 2–3 years before you can harvest spears. But the genetic diversity of seedlings often yields more resilient plants than cloned crowns, and you'll have dozens of plants for the price of a few berries. For the gardener who plays the long game, it's one of the most rewarding propagation projects around.
