To get started, let’s discuss how to plant celery seeds or seedlings, which can be done directly into the garden in early spring when the weather is cooler. Timing is everything for successful germination.
Sowing Celery Seeds
When sowing celery seeds indoors, it’s essential to provide them with adequate light and warmth. Start by filling a seed tray or small pots with a good quality seed starting mix. Sow the seeds about 1/8 inch deep and 1-2 inches apart. Cover the seeds with a thin layer of the mix and gently water.
For direct sowing into the garden, choose a spot that receives partial shade to full sun and has well-draining soil. Prepare the bed by loosening the soil to a depth of about 12 inches. Sow the seeds 1/8 inch deep and 2-3 inches apart in rows that are 18-24 inches apart. Water the soil gently but thoroughly.
Remember, celery seeds require consistent moisture to germinate. Keep the soil consistently moist during the first few weeks after sowing. You can expect the seeds to germinate within 1-2 weeks under optimal conditions. Once the seedlings have 2-3 sets of leaves, you can transplant them into individual pots or directly into the garden, depending on your preference.
Transplanting Celery Seedlings
Transplanting celery seedlings from pots to the garden bed can be a bit tricky, but with the right approach, you’ll be enjoying crunchy stalks in no time. Before transplanting, make sure your seedlings have at least two sets of true leaves and are large enough to handle being moved without shock.
Choose a cloudy or overcast day for transplanting to reduce stress on the seedlings. Dig holes that are slightly larger than the pots, spacing them 8-10 inches apart in well-draining soil with a pH between 6.5 and 7.0. Gently remove the seedling from its pot, taking care not to disturb the roots.
Place the seedling in the hole at the same depth as it was in the pot, firming the soil around it to prevent air pockets. Water thoroughly after transplanting to settle the soil. If you’re planting multiple seedlings, space them evenly and water each one individually to ensure they get enough moisture. With proper care, your celery plants should establish themselves quickly and be ready for harvest in about 60-90 days.
