Growing Tips
- 1Celery thrives in full sun, so ensure it gets at least 6 hours of sunlight daily.
- 2Keep the soil consistently moist but not waterlogged, as celery requires regular watering to prevent the stalks from becoming tough.
- 3Use rich, well-draining soil with plenty of organic matter, and space plants about 8-10 inches apart to allow for proper air circulation and growth.
- 4To manage pests, consider using row covers or introducing beneficial insects like ladybugs to control aphids naturally.

Step 5
Saving Seeds
How to Save Seeds
Saving seeds from your celery plant is a rewarding and simple process that any new grower can master! Allow your celery plant to flower and form seed heads, which look like small clusters of tiny seeds. Once the seed heads turn brown and dry on the plant, gently cut them off and place them in a paper bag. Shake the bag to release the seeds, then remove any plant debris. Store your seeds in a cool, dry place in a labeled envelope or jar, and they’ll be ready for planting next season. With just a little patience, you’ll have your own homegrown celery seeds—proof that you can do it!
