Growing Flat leaf parsley from seed

Soak seeds overnight before sowing.

Leaching can also speed up germination by washing away a chemical on the seedcoat which inhibits germination. To leach the seeds: soak them overnight, strain them and run water over the seeds (in the strainer) every few hours. When leaving the seeds for more than a few hours, place the seeds into a plastic bag to ensure that they do not dry out. Recommendations differ on how long to leach the seeds and though 24 hours is commonly recommended, leaching the seeds for as long as three days has been reported to produce quick germination results.

Look to ensure a distance 7.8 inches (20.0 cm) between seeds when sowing - bury at a depth of at least 0.25 inches (0.64 cm) deep. Soil temperature should be kept higher than 10°C / 50°F to ensure good germination.

By our calculations*, you should look at sowing Flat leaf parsley about 35 days before your last frost date .

Transplanting Flat leaf parsley

Transplant as soon as they have two sets of true leaves (and the soil is warm), because they have a long root and resent being transplanted once they have begun to leaf out. If you’re growing them in a pot for the kitchen window, select a container that is long and narrow rather than wide and shallow, to give the root room to run.
If planting into the garden, pick a spot that is handy to reach from the kitchen.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Flat leaf parsley is a hardy plant.

Harvesting Flat leaf parsley

Harvest outer leaves by gently twisting the stem away from the base of the plant.

To preserve parsley, you can either dry or freeze it.

Air drying Parsley: To dry parsley without a dehydrating machine, simply hang upside-down in small bunches in a cool, dark place. check that they are ready by crumbling a little in your fingers – if ready put into small airtight jars to keep until use.

Freezing Parsley: pack ice cube trays with parsley leaves and then cover with hot water (the hot water should blanch the parsley quickly and keep the colour nice and green). Place in the freezer for at least 24 hours, then place in freezer bags and store to defrost when required. Alternatively, blend parsley leaves in a food processor with oil to a smooth paste consistency, then pour into ice cube trays. After 24 hours, remove from the trays and place into freezer bags and store frozen until required.
