Growing Tips

  • 1Plant oats in a sunny spot with well-draining soil, ensuring they receive at least 6 hours of sunlight daily.
  • 2Water them regularly, keeping the soil consistently moist but not waterlogged.
  • 3Space the seeds about 1 to 2 inches apart to allow for proper air circulation, which helps prevent disease.
  • 4For pest control, monitor for common pests like aphids and use insecticidal soap if needed.

How to Harvest

  • 1Harvest oats when the grains are firm and have a golden color, typically in late summer.
  • 2Cut the stalks close to the ground using a sharp sickle or scythe, being careful not to damage the remaining plant base.
  • 3Bundle the cut stalks and allow them to dry in a well-ventilated area before threshing.

Step 5

Saving Seeds

How to Save Seeds

Saving seeds from your oats plant is a simple and rewarding process that any new grower can master! Once your oats have matured and the seed heads turn golden and dry, simply cut the stalks and let them dry further in a cool, airy place. Gently rub the seed heads between your hands to release the seeds, then sift out any chaff. Store your clean, dry oat seeds in a paper envelope or glass jar, and keep them in a cool, dry spot—like a pantry or cupboard—until you’re ready to plant again. With just a little effort, you’ll have your own homegrown oats to sow next season!
