How to Grow
Start Parsley Italian Giant seeds indoors or outdoors throughout the year in well-drained soil, ideally in a sunny or partially shaded spot such as a windowsill, container, or garden bed near the kitchen for easy picking. This flat-leaf parsley prefers full sun or light shade to develop its zesty flavour. Sow from January to December to enjoy fresh leaves year-round.
Sowing
Sow the seeds thinly on damp, well-drained soil and cover them very lightly. Keep the soil moist and place the container or bed in a warm, bright spot to encourage the slow germination typical of parsley.
Growing
Once seedlings appear, thin them to about 20cm apart to allow space for each plant to grow into a bushy clump reaching around 40cm tall and 30cm wide, suitable for 20cm pots. This spacing supports healthy leaf development whether grown in containers or garden beds.
Plant care
Maintain consistent watering, especially during warm weather, to keep the soil evenly moist. Regularly pick leaves to encourage fresh growth, and feed the plants lightly every few weeks to maintain productivity. As a biennial, the parsley will flower in its second year, at which point leaves become tougher, so many gardeners prefer to sow fresh seeds when flowering begins.

Yes, Parsley Italian Giant grows well indoors on a bright windowsill. Use a pot with drainage holes, keep the compost moist but not waterlogged, and give the plant as much light as possible.
Parsley is rich in vitamins A, C and K, and is often used to support digestion and add fresh, bright flavour to meals.
Italian parsley grows best in full sun but also copes well with partial shade. In very hot spots, a little afternoon shade helps keep plants lush and stops them drying out too quickly.
Parsley is a biennial, which means it usually produces leaves in its first year and flowers in its second. Once it flowers, the leaves become tougher and the plant will eventually decline, so many gardeners sow fresh parsley each year for the best harvest.
