How to Grow Parsley

How to Grow Parsley: Use fresh seed each year. Soak seed in warm water for 24 hours before sowing.

Learn how to grow parsley in minutes. Parsley is a biennial herb usually grown as an annual. There are two types of parsley: curly leaf parsley has finely divided, ruffled leaves and grows from 8 to 12 inches tall; flat-leaf parsley has flat, bright, green leaves that resemble a celery stalk and grows 18 to 24 inches tall. Flat-leaf parsley is also called French of Italian parsley.

Parsley is a favorite of most Western cooks—used for its clean, fresh taste in sauces, salads, stuffings, and omelets. It’s commonly added at the end of cooking for its fresh peppery and tangy flavor. It has a light spicy aroma with hints of anise and lemon.

 Parsley grows to its full size the first season and after winter’s cold temperatures, it blooms, sets seeds, and dies in its second season. If you are growing parsley for kitchen use and not seed, you may want to simply treat the plant as an annual and plant it anew each spring.

  • Botanical name: Petroselinum crispumneapolitanum (flat or plain-leafed parsley, also called Italian parsley); Peroselinum crispum (curly leafed parsley. Parsley is a member of the Apiaceae – carrot and parsley family.
  • Origin: Eastern Mediterranean
  • Type of plant: Biennial plant is usually grown as an annual.
  • Growing season: Spring through fall
  • Growing zones: Zones 5 to 9
  • Hardiness: Parsley can withstand frost but does not tolerate very hot weather; plants thrive in soil between 60°F and 65°
  • Plant form and size: Grows 12 to 20 inches tall in clumps of deep green foliage.
  • Flowers: White to yellowish-green flowers grow on flat clusters called umbels; flower stalks form in the second year growing to 24 inches high
  • Bloom time: Blooms early to midsummer in the second year.
  • Leaves: Rosette of dissected leaves that resemble carrot leaves. Curly parsley leaves are tufted and finely cut with serrated or toothed edges and wrinkled surfaces. Plain-leaf or Italian is similar but has a flat surface. Individual leaves consist of a leafstalk, side branches, and several separate leaflets.

  • Best location: Grow parsley in morning sun or partial shade in the afternoon. Parsley grows best where the air temperature is about 60° to 65°F. In hot summer regions, start parsley outdoors in the fall and let it grow on through the winter.
  • Soil preparation: Parsley grows best in compost-rich, moist soil with a pH between 5.5 and 6.7. Add a slow-release fertilizer to the soil before or at planting time.
  • Seed starting indoors: Sow parsley indoors in late winter or early spring 4 to 6 weeks before transplanting to the garden. Soak seeds in warm water for 24 hours before planting. Seeds germinate in 5 to 6 weeks and plants mature in 70 to 90 days.
  • Transplanting to the garden: Transplant parsley outdoors in mid to late spring after the soil has warmed to 50°F.
  • Outdoor planting time: Sow parsley seed outdoors in spring after all danger of frost has passed and the soil is at least 50° Parsley is slow to germinate and emerge from the soil—usually 5 to 6 weeks after sowing. For best germination soak seed overnight in warm water before sowing or pour boiling water in the planting hole before sowing seed. In mild winter regions and hot summer regions, sow seed outdoors from early winter to late spring.
  • Planting depth: Sow parsley seed ¼ inch deep.
  • Planting and spacing. Space parsley 6 to 8 inches apart in all directions.
  • How much to plant: Grow 6 plants for cooking; grow 10 to 20 plants for preserving.
  • Companion planting: Grow parsley with asparagus, sweet corn, peppers, and tomatoes. Parsley is said to repel asparagus beetles and reduces the number of carrot rust flies. It’s best to grow parsley apart from like family plants including carrots, celery, and parsnips to avoid cross-pollination.

  • Watering: Keep the soil evenly moist; do not overwater parsley.
  • Feeding: Parsley is a heavy feeder. Feed parsley with liquid seaweed extracts two to three times during the growing season. Side-dress parsley with aged compost in midseason.
  • Mulching: Where the weather gets hot, mulch around plants to keep the roots cool; be sure not to cover the crown which can cause rot.
  • Care: To keep parsley productive, cut back the full length of outside stems (cut at the base). Remove flower stalks that form. (When flowers are allowed to remain, the leaves will become bitter.) Prune away dead leaves as needed to keep the plant tidy. Towards the end of the growing season, cut back plants to promote new growth.
  • Container growing: Parsley grows and yields well in a container. Choose a container at least 6 inches wide and deep. Grow parsley indoors in summer or winter in 6-inch pots.
  • Winter growing: Bring parsley indoors for winter harvest and to avoid freezing damage and continue cut-and-come-again harvest. Parsley leaves grown in the house will be tougher than those grown outdoors.

Troubleshooting Parsley

  • Pests: Cabbage loopers, carrot rust flies, carrot weevils, whitefly, nematodes, parsley worms, and spider mites can attack parsley. The brightly striped parsley worm caterpillar which becomes the swallowtail butterfly will feed on parsley. You may want to plant enough parsley to feed the parsley worm caterpillar to support a butterfly colony. Whiteflies can attack parsley in large numbers. Spray the undersides of the leaves thoroughly with insecticidal soap to control whiteflies. Give leaves an occasional rinse to keep spider mites from infecting plants.
  • Parsley usually is not attacked by disease if planted in well-drained soil. Crown rot can occur if the soil is too wet and not well-drained. Leaf spot can occur if watering is sparse or the weather is hot.

How to Harvest Parsley

  • When to harvest: Gather parsley stems and leaves as you need them. Parsley will mature 70 to 90 days after sowing. Harvest leaves before plants flower; once flower spikes form, the leaves will be bitter tasting. At the end of the season, let parsley flower, collect the seeds to replant next year.
  • How to harvest: Cut outer leaf stalks at the base for fresh foliage (let inner leaves continue to grow). Cut the whole plant at once and it will re-grow. Harvest parsley by cutting the leafy stems from the base of the plant—this will also serve to make the plant grow back bushier. Harvest the larger, outer leaves first. Dig roots in fall of the first year or spring of the second year using a garden fork.

  • Flavor and aroma: Flat parsley has a stronger more pungent taste than curly parsley; use it sparingly so that it does not overpower other flavors. Parsley will tone down strong flavors such as garlic. Parsley is a chief ingredient in bouquet garni.
  • Leaves: Use first year leaves with salads, sandwiches, eggs, vegetables, meats, soups, stews, roasts, sauces, and vinegar. Strip leaves from coarse stems before chopping. Add leaves to green salads, potato salad, cold pasta dishes or mince over deviled eggs. Add parsley to any savory dish, fish, and poultry. Add parsley to cottage cheese, soft cheese such as ricotta, and herb butter. Second-year leaves are unpalatable.
  • Cooking: Parsley added at the last minute to cooked foods will be crisper, tastier, and greener. Flat-leaf parsley is the best flavor choice for cooking. Parsley tastes good with omelets, stews, vegetables, soups, eggs, sauces, rice, and pasta, also with fish, shellfish, meat, and poultry.

  • Refrigeration: Store fresh parsley in a plastic bag in the refrigerator or sprinkle with water and wrap in a paper towel, or cut the ends and place stems upright in cold water.
  • Drying: Dry leaves in the refrigerator; wash them first then let them air dry spread on a baking sheet covered with paper towels. Leaves will take 2 to 7 days to dry in the fridge. Hang dry parsley in bunches or in a mesh bag to hang dry; hang dry parsley in the shade. Dried parsley quickly loses flavor; freezing leaves may be a better alternative.
  • Freezing: Chop and freeze leaves in a zippered plastic freezer bag. Freezing will retain the flavor.
  • Storing: Dried parsley leaves should be kept in an airtight container away from light and moisture.

Propagating Parsley

  • Seed: Pour boiling water over seed before sowing or soak seed in warm water for 24 hours or refrigerate or freeze seed before sowing. Let a few plants go to seed at the end of the season; they will reseed for next year.

Parsley Varieties to Grow

  • Choose from these parsley varieties: ‘Giant Italian’ and ‘Giant of Naples’ are flat-leaf Italian parsley for cooking; ‘Moss Curled’ and ‘Extra Curled’ are curly-leaf parsley.

  1. I just finished this bit about Parsley and must tell you that there is an excellent way to dry it. but, first only the curled parsley works well with this method. I cut the tops from the stems and throw in a paper bag in the fridge. It dries so well, keeps a beautiful green colour, is crisp and very aromatic. this works best once you have more than one plant and they are quite large. I will cut back and snip the tops from a whole plant. I fold the top of the bag and label with the date, then shake the bag once every two days until completely dry. For those of you with cool/cold winters doing this two to three times in season will probably provide enough dry parsley to last until spring. Blessings.

  2. I have been growing Italian parsley and curly parsley next to each other in a raised bed. They were doing well until I noticed that some leaves of the Italian parsley curled up slightly. The curl started from the new leaves and continued after the leaves grew bigger. There were normal leaves and the curled ones on the same plant. Unlike the matt colour of the normal leaves, the curled ones looked shiny especially the under side. Colour wise, both were green, but the green of the curled leaves was lighter than the normal ones. I checked online for the possible cause. Two reasons came out: celery mosaic virus and Aster yellows, but the symptoms did not match exactly. To make it more interesting, the coriander/cilantro plants that were in a pot nearby also started to grow the curly and shiny leaves which were not there initially. The characteristics of the curled leaves of both herbs were very similar. The flavour of the curled leaves of both herbs was still very good. Is this normal? Shall I be worried? Do I need to do anything? Thanks!

    • Curled and shiny leaves on plants in different soil but close proximity: check carefully for sap-sucking insects such as spider mites, thrips, or aphids. The shine and curl could be the result of sap-sucking insects drawing plant juices from the plant, this would cause the curl and could cause the tissue to be both thin and shiny or papery. Wash the plants to knock off insects. Be sure to keep the soil just moist, not wet but never dry.

  3. Karen…. I’m new to this so I was wondering once they are completely dried can I put them in a mason jar and save them then? You said you shake bag every 2 days-about how many days does it take? Thanks for any tips Judy
