Celery Seeds,
Chinese White

Start seeds indoors 8-10 weeks before the last expected frost date in your area. For cooler climates, planting in late spring or early summer is ideal, while in warmer climates, early spring or fall planting is recommended. Once the seedlings have at least two sets of true leaves, they can be transplanted outdoors when the night temperatures consistently stay above 50 F​.

Sow Chinese White celery seeds about 1/8 inch deep in seed trays or pots filled with a quality seed starting mix. Maintain a temperature of around 70-75 F for optimal germination. Once the seedlings are established, thin them to ensure proper spacing. Before transplanting, harden off the seedlings by gradually exposing them to outdoor conditions. Prepare the garden bed by incorporating compost or well-rotted manure to enrich the soil and plant the seedlings about 10 inches apart.. Mulching around the plants helps conserve moisture and control weeds.

Regularly water the plants deeply, especially during hot and dry spells, and avoid overhead watering to reduce the risk of foliar diseases. Apply a balanced fertilizer every four weeks to promote healthy growth, but avoid excessive nitrogen, which can lead to lush foliage at the expense of flavor. Pruning yellow or damaged leaves helps redirect the plant's energy towards producing fresh foliage, and thinning ensures adequate spacing for healthy air circulation​​.

• Celery and celeriac are insect pollinated and should be isolated by 1 mile from each other to ensure seed purity.
• Both plants are biennial and must either be dug and stored or be left in the ground to overwinter and flower the following spring.
• Harvest the seeds when they have completely dried on the plant.
• When stored properly, celery and celeriac seeds will last for 5 years or more.
