Caring for Parsley

Parsley has moderate water needs and performs best when the soil is kept consistently moist, especially during dry spells in late spring and summer. Water regularly at the base of the plant, aiming for the soil rather than the foliage to reduce the risk of fungal issues. In hot, dry weather, water two or three times a week; in cooler or wetter periods, once a week is usually sufficient. Mulching around plants with compost or well-rotted manure helps retain soil moisture and keeps roots cool. Feed parsley lightly in April with a balanced general-purpose fertiliser or a top-dressing of compost. Because it's grown for foliage rather than flowers or fruit, avoid high-nitrogen feeds that promote excessive soft growth at the expense of flavour. One spring feed is generally enough for the season, though container-grown parsley may benefit from a weak liquid feed every four to six weeks during active growth. Parsley is hardy to zone 5a and will often overwinter outdoors in temperate Europe, particularly flat-leaved varieties. In colder areas or exposed sites, protect plants with fleece or cloches from November onwards. First-year plants are more likely to survive winter than second-year specimens. Common pests include aphids and carrot root fly (parsley and carrots share the same family). Cover young plants with fine mesh if carrot fly is a problem in your area. Slugs can damage seedlings, so use organic pellets or barriers if necessary. Parsley is generally disease-resistant, though overwatering or poor drainage can lead to root rot or powdery mildew on the leaves.
