How Long Does Parsley Take to Grow? Full Timeline + Tips

By Emma Johnson · January 24, 2026

Parsley typically takes 70 to 90 days to reach full maturity from seed, but you can begin harvesting leaves as early as 45 to 60 days after planting. Growth time depends on variety, growing conditions, and climate. This article explores the full growth timeline, optimal care practices, and tips for faster, healthier parsley development.

Understanding Parsley Growth Stages

Parsley (Petroselinum crispum) is a biennial herb commonly grown as an annual for its flavorful, nutrient-rich leaves. Knowing each growth stage helps gardeners plan and optimize harvests.

Germination Phase (14–28 Days)

Parsley seeds are notoriously slow to germinate due to natural compounds that inhibit sprouting. Pre-soaking seeds in warm water for 24 hours can reduce this phase by up to 50%.

Optimal soil temperature: 70°F (21°C)
Soil moisture: Consistently moist, not soggy
Light requirement: Indirect light until emergence
Germination rate: Typically 60–80% under ideal conditions

Seedling Development (Days 28–60)

After sprouting, seedlings develop their first true leaves. This stage is critical for establishing strong root systems.

Thin seedlings to 6–8 inches apart
Provide 4–6 hours of direct sunlight daily
Fertilize lightly with balanced liquid fertilizer every 2–3 weeks
Protect from pests like aphids and slugs

Mature Growth and Harvesting (Days 60–90+)

By day 60, most parsley plants are ready for initial harvest. Full maturity occurs around 70–90 days, depending on variety.

Harvest outer leaves first to encourage new growth
Regular picking promotes bushier plants
Peak flavor occurs just before flowering (bolting)
In mild climates, parsley can overwinter and produce for a second year

Factors That Influence Parsley Growth Speed

Several environmental and cultural factors affect how quickly parsley grows and when it becomes harvestable.

Temperature and Climate

Parsley thrives in cool to moderate temperatures between 60°F and 75°F (15°C–24°C). High heat accelerates bolting, reducing leaf quality.

Soil Quality

Well-draining, loamy soil rich in organic matter supports robust growth. A pH between 6.0 and 7.0 is ideal.

Watering Practices

Consistent moisture is key—allow top inch of soil to dry between waterings. Overwatering leads to root rot; underwatering stresses the plant.

Sunlight Exposure

Full sun (6+ hours) yields the best results, though parsley tolerates partial shade, especially in hot climates.

Variety	Average Days to Harvest	Height at Maturity	Leaf Type	Cold Tolerance
Curly Leaf Parsley	75	10–12 in	Crisped, decorative	Moderate
Italian Flat-Leaf Parsley	70	12–18 in	Smooth, broad	High
Hamburg Root Parsley	90–100	18–24 in	Less leafy	Very High
Evergreen Hardy	72	10–14 in	Semi-curled	Very High
Forest Green	68	12 in	Dark green, curled	Moderate

Table data source:1, 2, 3

The table shows that flat-leaf and newer hybrid varieties like Forest Green mature slightly faster than traditional curly types. Hamburg root parsley, grown for its edible taproot, requires the longest growing season. Cold-hardy cultivars such as Italian and Evergreen Hardy perform better in fall and winter gardens, extending harvest windows.

Tips for Faster and Healthier Parsley Growth

To shorten growth time and improve yield, consider these proven strategies:

Pre-soak seeds: Soak in warm water for 24 hours before sowing to speed germination.
Use bottom heat: When starting indoors, place trays on a heat mat set to 70°F (21°C).
Start indoors: Begin seeds 6–8 weeks before last frost to get a head start.
Choose fast-maturing varieties: Opt for 'Forest Green' or 'Italian Flat-Leaf' for quicker harvests.
Mulch to retain moisture: Organic mulch helps maintain consistent soil hydration and temperature.
Avoid overcrowding: Thin plants early to allow airflow and reduce disease risk.

Common Questions About Parsley Growth Time

How long does it take for parsley to grow from seed?

Parsley takes 14 to 28 days to germinate and another 45 to 60 days to reach harvestable size, totaling 60 to 90 days to full maturity depending on conditions and variety.

Can I harvest parsley before it's fully grown?

Yes, you can begin harvesting parsley once the plant has at least 8–10 leaves, typically around 45–60 days after planting. Always pick outer stems to promote continued growth.

Why is my parsley growing so slowly?

Slow growth may result from poor germination due to old seeds, cold soil, inconsistent watering, insufficient light, or compacted soil. Ensure optimal temperature, moisture, and nutrient levels for best results.

Does parsley grow back after cutting?

Yes, parsley regrows after cutting if harvested properly. Cut outer stems near the base, leaving the inner growth intact. With regular pruning, parsley can produce for several months.

Is parsley easy to grow for beginners?

While parsley has a slow start, it is relatively low-maintenance once established. It’s a great herb for beginners who are patient and provide consistent care, especially during germination.
