Greenhouse Gardening - How to Grow Parsley?

Apr 19, 2017 0 comments

Parsley is a flowering herb rich in Vitamins A and C and Iron. Used mostly to garnish food, it is a common ingredient in East European and Mediterranean cuisines. You can grow it in a greenhouse with a simple process that includes:


  • If you plan to do wholesale parsley cultivation, buy greenhouse kits that do not have a slab base so you are able to cultivate a patch in your greenhouse and plant the seeds directly in the soil. However, you can make raised garden beds in such greenhouses or, you can plant the herb in hanging pots.
  • You should start about two or three weeks ahead of the last spring frost because sprouting parsley seedlings are considerably poor at tolerating frosty conditions.
  • The optimal spacing is 6 to 8 inches between the seeds.
  • Ensure the soil is rich and moist. Well-composted manure is ideal for enriching the soil before planting parsley.
  • The herb has slow-sprouting seeds so soak them a day before planting, preferably in warm water.
  • The optimal temperature for growing parsley should be between 65 and 75 degrees Fahrenheit.

Tips and tricks

  • The plant is biennial and, new plants produce leaves with better flavor so consider doing a fresh plant every year.
  • To keep your parsley moist and cool, apply mulch around each plant.

Common problems

- Some common diseases that affect parsley in greenhouses are leaf spots and stem rot. Some problematic pests, on the other hand, are carrot flies and the larvae of black swallowtail and celery flies.

Watering requirements

  • Before and after germination, 20 millimeters per week but, this is only necessary until the sixth week after germination. However, you may need to water the plants during the summer months to ensure the plants do not dry out; between 5 and 10 millimeters of water per week is sufficient.

Soil requirements

  • Parsley thrives in rich, moist soils with pH that ranges between 5.5 and 6.7.

Lighting requirements

  • The herb does well in full sun. However, it thrives in partially shaded areas just as well.


  • In greenhouses, parsley matures 10 to 12 weeks after planting. To harvest, snip the leafy stems at the base of the plant or just collect the leaves as necessary.
