Why Grow Triple Curl Parsley?
Parsley is one of those herbs that belongs in every garden or kitchen windowsill. The Triple Curl variety offers unique benefits:

Its tidy growth habit makes it ideal for small spaces, patios, and windowsills.
Growing Conditions for Triple Curl Parsley
Parsley is easy to grow when you give it the right environment. It’s adaptable but thrives with these basic conditions:
Sunlight
- Full sun is best (6–8 hours daily).
- Will tolerate partial shade, especially in hot summer climates.
Soil
- Loose, rich soil with good drainage.
- pH between 6.0 and 7.0 is ideal.
- Add compost or organic matter before planting to boost nutrients.
Watering
- Keep soil evenly moist, not soggy.
- Deep watering 1–2 times per week works well.
- Mulch around plants to retain moisture and keep leaves clean.
Temperature
- Prefers cool to mild conditions (50–75°F).
- Can handle light frost, especially with mulch or row covers.
Planting Triple Curl Parsley
From Seed
Parsley seeds germinate slowly, often taking 2–4 weeks. Patience pays off.
- Soak seeds overnight in warm water to speed sprouting.
- Sow ¼ inch deep in prepared soil or seed-starting mix.
- Keep consistently moist until seedlings emerge.
- Thin seedlings to 8–10 inches apart once they develop true leaves.
From Transplants
Buying young plants saves time.
- Plant outdoors after the last frost date.
- Space 8–10 inches apart in rows or containers.
- Water well after planting to help them settle.
Container Growing Tips
Triple Curl parsley thrives in pots as small as 8–10 inches wide. Use high-quality potting mix and place in a sunny spot. Keep containers watered more frequently than garden beds—they dry out faster.
Pro tip: Combine parsley with other herbs like thyme or oregano for a compact, culinary container garden.
Caring for Triple Curl Parsley
Feeding
- Fertilize every 4–6 weeks with balanced organic fertilizer.
- Too much nitrogen can lead to lush leaves with less flavor.
Pruning and Harvesting
- Harvest outer leaves first, allowing inner growth to continue.
- Frequent cutting encourages more foliage.
- Avoid cutting more than one-third of the plant at a time.
Mulching
- Apply a light mulch to conserve moisture and prevent weeds.
- Straw, shredded leaves, or compost work well.
Overwintering
- In mild zones, parsley may overwinter outdoors with mulch.
- In colder regions, grow in pots you can bring indoors to a sunny windowsill.
Pests and Problems
Parsley is mostly trouble-free, but watch for:
- Aphids: Wash off with water or use insecticidal soap.
- Parsley Worms (Swallowtail Caterpillars): They’re harmless to humans and turn into butterflies. Consider sharing your harvest with them.
