Growing Tips

  • Parsley is biennial — it overwinters in most zones and comes back in spring before bolting.
  • Soak seeds overnight before planting to speed up notoriously slow germination.
  • Start indoors 8–10 weeks before transplanting.
  • Flat-leaf (Italian) parsley has more flavor than curly for cooking.
  • Cut outer stems at the base — never strip from the center.

Common Mistakes

  • Expecting fast germination — parsley can take 3–4 weeks. Be patient.
  • Not soaking seeds — significantly speeds up germination.
  • Harvesting from the center — always take outer stems to keep the plant productive.
  • Letting it go to seed in year 2 without harvesting — once it flowers, leaf production stops.

Companion Planting
