Frequently Asked Questions

What pest or disease commonly affects Petroselinum crispum (flat-leaf Italian parsley), and how do I treat it?

Flat-leaf Italian parsley (Petroselinum crispum) is prone to leaf spot and, in damp weather, early blight-like spotting from fungal pathogens. Remove the most affected leaves, improve airflow by spacing plants, and water at the soil line rather than overhead; avoid wet foliage at night. If spotting persists, use a labeled fungicide that’s appropriate for edible herbs and follow the label’s pre-harvest interval.

How often should I water during the main growing phase for Petroselinum crispum var. neapolitanum?

Keep the top 1–2 inches of soil consistently moist while plants are establishing, because parsley has slow, uneven germination and shallow feeder roots. After plants are established, water deeply about 1–2 times per week to maintain steady moisture—more often during hot spells—so soil never dries out fully between waterings. Use part-sun conditions to reduce evaporation, but don’t let the crown sit in waterlogged soil.
