How to grow Parsley
Planting
Sow from March to July where it is to grow, or in modules. Germination is slow and uneven — three to five weeks is normal, and warm soil helps. Sow a second batch in midsummer for autumn and winter picking, and thin to about 15 cm apart.
Pruning
Pick outer stems from the base rather than shearing the top, and the plant keeps producing. Remove flowering stems if they appear in the first year.
Propagation
From seed only. It does not transplant well once the taproot is established, so sow direct or use modules and plant out young.
Pests and diseases
Carrot fly attacks the roots of parsley as well as carrots; a fine mesh cover or a fleece barrier is the practical answer. Slugs take seedlings, and aphids gather on flowering stems.
Value to wildlife
If left to flower in its second year the flat umbels attract hoverflies and small parasitic wasps.
Notes
Parsley is biennial: it makes leaf in year one, flowers and sets seed in year two, then dies. Sow fresh every year rather than trying to keep old plants going. Flat-leaved types generally have more flavour, curled types stand winter better.
