Frequently Asked Questions

What pest or disease most commonly affects Petroselinum crispum var. neapolitanum (Italian flat-leaf parsley), and how do I stop it?

Leaf spot and damp-related fungal problems are common, especially when foliage stays wet and soil drains poorly. Water at the soil line, improve airflow by spacing plants so leaves don’t stay crowded, and remove any spotted leaves immediately; if it’s spreading, switch to a labeled garden fungicide appropriate for edible herbs. Watch for aphids on tender new growth and spray them off with a steady jet of water, repeating as needed because parsley regrows quickly.

How often should I water giant Italian flat-leaf parsley during the main growing phase?

Keep the top 1–2 inches of soil consistently lightly moist from sprouting through the main leaf-producing period, but never waterlogged. In warm weather, that usually means watering about 2–3 times per week, adjusting to rainfall and how fast your soil dries; sandy beds may need more frequent watering while heavier soils need less. If leaves start drooping and the soil dries out, water deeply once rather than frequent light sprinkling to encourage steady root growth.

How can I tell when Petroselinum crispum var. neapolitanum is ready to harvest (around 70 days)?

Harvest when plants have formed a full rosette of mature, flat leaves about 8–12 inches tall—typically near 70 days from sowing under good conditions. Pick outer stems first by cutting close to the base or snipping individual leaflets, leaving the center to regrow. Don’t wait for bolting; once flower stems start forming, leaf flavor declines and regrowth slows.

A lush, slow-to-bolt green—Giant Italian parsley delivers a vivid, fresh aroma with an unmistakably full-bodied flavor. Expect broad, deeply crinkled leaves that hold their texture beautifully, making this variety a standout for garnishing and flavoring throughout the season. Grow Giant Italian for dependable, vigorous harvests at about 70 days, with enough foliage to keep your beds looking richly alive while your pantry stays bright with herbal character.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 28°F before moving outdoors. Harden off for 7 days first.

Expert Note

Soak seeds 12–24 hours and keep evenly moist—parsley can be slow to germinate, especially in cool springs.
