FAQ and sources

When should you sow parsley?

Sow parsley directly when the soil is at least 10 °C, with nights above about 1 °C. It tolerates cool weather and has a good autumn window, but it germinates slowly: do not expect instant emergence. Keep the seedbed moist until seedlings appear, because if the seed dries during germination the row becomes patchy. Sow in shallow rows or a wide pot, covering lightly. Harvest usually starts after 80-100 days, then continues for a long time.

Why does parsley fail to germinate?

Parsley is known for slow, unreliable germination. The most common causes are cold soil, old seed, sowing too deep, or letting the seedbed dry out. Use fresh seed, cover lightly, and water gently. It can help to soak the seeds for a few hours before sowing, then sow in fine soil. Do not hoe the bed immediately thinking it has failed: parsley can take much longer than arugula or radishes.

How do you harvest parsley without damaging the plant?

Cut the outer stems at the base, leaving the central heart growing. Avoid taking only the leaflets and leaving bare stalks: the plant regrows better from a clean cut. Harvest regularly but do not strip the plant completely, especially after heat or cold. Parsley produces well in cool, fertile soil. In pots, after frequent cutting, a light organic feed can help support new leaves.

Does parsley grow better in sun or shade?

Parsley grows in sun during cool seasons, but in summer it prefers partial shade or morning sun. Strong heat stresses it, dries the soil, and makes leaves tougher. Keep the soil cool with mulch or a large pot. On a balcony, avoid small black pots exposed all day: they overheat and stop the roots. A bright but not scorching position gives more tender leaves and longer harvests.

Can parsley be grown in autumn?

Yes. Parsley is well suited to autumn. If sown or started in time, it keeps producing leaves in cool seasons and can handle moderate cold with protection. In autumn, watch moisture and waterlogging: roots dislike constantly wet soil. In mild climates it can stay productive for a long time. Remember that parsley is biennial: in the second year it tends to flower, so resow for high-quality leaves.
