How to Grow Parsley: A Long Season From One Slow Start

Parsley is the quiet workhorse of the herb bed. It doesn't bolt at the first warm day the way cilantro does, it keeps producing for a long season, and it's content in a pot, a border, or the gaps between bigger plants. The only thing it asks for is patience at the very start: parsley is famously slow to germinate, and most "failed" sowings were simply given up on too soon.

Start with the slow germination

Parsley seed can take two to four weeks to come up, which trips up gardeners used to radishes appearing in days. Don't assume it failed. Soaking the seed overnight before sowing speeds things along, and keeping the soil consistently moist through that long wait is the real key. Let the surface dry out once and you can lose the flush. Sow about a quarter inch deep, and if you want a head start, parsley is one of the few herbs that transplants reasonably well from an indoor seed-starting tray, as long as you don't damage the taproot.

Cool start, long haul

Parsley is a biennial grown as an annual: it makes leaves its first year and only flowers and sets seed in its second. That's good news, because it means a spring planting keeps giving leaves right through summer and well into fall, shrugging off light frost that finishes tender herbs. Start it in the cool of spring in full sun to part shade — it's one of the more shade-tolerant herbs, so it's a fine choice for a spot that only gets a half day of light. Keep it evenly watered and feed lightly through the season to keep new leaves coming.

Flat-leaf or curly

The two types are interchangeable in the garden and differ mainly in the kitchen. Flat-leaf (Italian) parsley has a stronger, cleaner flavor most cooks prefer and is easier to wash and chop. Curly parsley is milder, holds up as a garnish, and makes a tidy, ornamental edging. Grow whichever you'll actually eat — the plant cares which you pick about as much as it cares what you call it.

Harvest parsley from the outside, all season

Parsley is a cut-and-come-again herb. Always harvest the outer, fully grown stems at the base, letting the new growth in the center keep coming — strip it from the top and you stall the plant. Regular picking is the whole maintenance routine; the more you cut, the more it makes. Take what you need through the season, and if you garden where winters are mild, a mulch blanket will carry a plant or two through to an early spring harvest before it bolts in its second year. Parsley also earns its keep near the vegetables — it draws in beneficial insects, so it's a tidy fit for companion planting. Find your sowing windows on the planting calendar.
