Growing Tips

  • 1Plant asparagus in a sunny spot with well-drained soil, as it thrives in full sunlight.
  • 2Water regularly, especially during dry spells, but avoid waterlogging the soil.
  • 3Space the plants about 12–18 inches apart to allow for proper growth and air circulation, which helps prevent disease.
  • 4Keep an eye out for common pests like asparagus beetles and use organic methods, such as handpicking or neem oil, to control them.

When to Pick

How to Harvest

  • 1Harvest asparagus in the spring when spears are 6-8 inches tall and about the thickness of a pencil.
  • 2Use a sharp knife or scissors to cut the spears at ground level, being careful not to damage the crown.
  • 3Stop harvesting when the spears become thin, allowing the plant to grow and store energy for the next season.

Step 5

Saving Seeds

How to Save Seeds

Saving seeds from your asparagus plant is a simple and rewarding process that any new grower can master! Once your asparagus plants flower and produce bright red berries in late summer or fall, simply pick the ripe berries and gently squeeze out the seeds. Rinse the seeds to remove any pulp, then let them dry completely on a paper towel for a few days. Store your dry seeds in a labeled envelope or airtight container in a cool, dry place until you’re ready to plant them next season. With just a little care, you’ll have your own homegrown asparagus seeds ready to start a new patch—saving seeds is easier than you think, and you’ve got this!
