How to Grow Parsley from Seed

Parsley grows best when you soak the seeds overnight, plant them in well-draining soil about a quarter-inch deep, and keep them consistently moist in partial shade. The seeds take 2-4 weeks to germinate, so patience is key. Once established, parsley gives you fresh herbs for months with regular harvesting.

Total time: 4 weeks
Hands-on: 30 min
Difficulty: Easy

Ingredients

1 parsley seeds
1 bowl room temperature water
1 compost
1 garden soil
1 potting mix

Step by step

Soak the seeds overnight. Drop your parsley seeds in a small bowl of room temperature water the night before planting. This softens the hard seed coat and cuts germination time in half.
Prepare your planting area. Choose a spot with morning sun and afternoon shade, or use containers with drainage holes. Mix compost into garden soil or fill pots with quality potting mix.
Plant the seeds. Scatter seeds on the soil surface, then cover with a quarter-inch of soil. Space them about an inch apart in rows or broadcast them in patches.
Water gently and consistently. Use a spray bottle or gentle shower setting to avoid washing away seeds. Keep soil damp but not waterlogged. Check daily and mist as needed.
Wait for germination. Seeds emerge in 2-4 weeks. You'll see tiny green shoots that look like grass at first. Keep watering consistently during this phase.
Thin the seedlings. When plants have 3-4 true leaves, thin to 4-6 inches apart. You can eat the thinned seedlings or transplant them to other spots.
Begin harvesting. Start cutting outer stems when plants reach 6 inches tall. Cut stems at the base, leaving the center to continue growing. Regular harvesting keeps plants productive.

Tips & troubleshooting

Mark your planting area clearly - parsley seedlings look like weeds at first
Plant extra seeds since germination rates are typically around 70 percent
Parsley tolerates light frost and often survives mild winters
Pinch off flower stalks to keep leaves tender and extend the harvest
Save some plants to go to seed if you want to collect seeds for next year

Variations

Flat-leaf parsley. Also called Italian parsley. Has broader leaves and stronger flavor. Grows slightly larger than curly varieties and handles heat better.
Curly parsley. The classic garnish variety with tightly ruffled leaves. Milder flavor than flat-leaf. More cold-tolerant and compact for container growing.
Container growing. Use pots at least 8 inches deep with drainage holes. Group several containers together to maintain humidity. Move pots to follow ideal light conditions.
Succession planting. Plant new seeds every 3-4 weeks for continuous harvest. Start indoors 6-8 weeks before last frost for earlier outdoor transplants.

Questions

Why are my parsley seeds taking so long to germinate?: Parsley seeds have a hard coat and naturally take 2-4 weeks to sprout. Cold soil slows this even more. Pre-soaking helps, and keeping soil consistently moist and warm speeds things up.
Can I start parsley seeds indoors?: Yes, start them 6-8 weeks before your last frost date. Use seed starting trays and transplant when seedlings have 4-6 true leaves and soil has warmed up.
How often should I water parsley seedlings?: Check daily and water when the top of the soil feels dry. Seedlings need consistent moisture but not soggy conditions. A light daily misting often works better than heavy watering.
When can I start harvesting parsley?: Begin cutting outer stems when plants reach 6 inches tall, usually 8-10 weeks after planting. Always leave the center growing point intact so the plant continues producing.
Will parsley grow back after cutting?: Yes, parsley is a cut-and-come-again herb. Harvest outer stems regularly and new growth emerges from the center. Plants can produce for months with proper care.
