How to grow parsley

1. Sow parsley seeds outdoors from early spring to early summer. Dig 1cm-deep trenches and sow the seeds along the trench, and then cover in water.

2. When the seedlings are big enough to handle, thin them to one plant every 15cm with 15cm between rows.

3. Make sure your plants are well watered, especially during summer, and feed a liquid fertiliser every few weeks.

4. Make sure you remove any flower heads to allow you to harvest your plant for longer. You can also cut off any lower leaves and shoots that turn yellow.

Common problems when growing parsley

Parsley is closely related to carrots and celery, so the RHS says it can be blighted by similar pests, including carrot fly and celery leaf miner.

Carrot fly is a small black fly whose larvae feed on the roots of parsley. Prevent an infestation by sowing seeds thinly and avoid crushing the foliage. You can also cover your plants with horticultural fleece or surround them with clear polythene to stop low-flying female flies. Sadly, there's nothing you can do if your plants do suffer from an infestation.

Celery leaf miners are small larvae that tunnel through leaves, leaving brown blisters and stopping growth. Make sure you pinch out affected leaves and grow your parsley under horticultural fleece or mesh to prevent it.
