The way to be successful when Growing Parsley is to remember that it requires a rich well dug soil, which has been enriched with organic matter, which is preferably grown in full sun. It can be grown in partial shade if the soil is good, particularly if bone meal has been added.
During March sow four to six seeds to a pot, water and cover with glass or polythene, be patient, parsley is often slow to germinate because it requires quite high temperatures, but can be between 7-14 days. Once germinated the glass or polythene can be removed and the pot placed in maximum light in a greenhouse or windowsill. When the seedlings have grown a little and have produced a pair of leaves they can be thinned to 3 per pot.
Once the seedling has reached about 8cm high it is ready to be planted outside. Harden the plants off by placing them outside in the day, remembering to bring them back inside at night, for 1 week and then leave them outside both day and night for another week.
Due to difficulties in germination and if you do not have a greenhouse, some people find it easier to grow parsley outside from plants brought from a garden centre. Be sure to select the right place in your garden before planting out as parsley does not like being transferred once established. Multiple plants should be placed approximately 15cm apart. The usual plant to harvest time is approximately 3 months. The plants should be kept weed free and for best results given a monthly feed of organic liquid feed.
Parsley is a low maintenance plant once established and is probably the most popular herb which can be grown in cooler areas.
Growing Parsley in containers is very popular and there are some containers made specially for the job, just remember to keep the growing medium moist especially if the container is made of terracotta as they will dry out more quickly. To reduce the chance of this happening line the pot with polythene, a plastic bag will do before filling with your chosen growing medium and place in a sunny spot. The most effective way to harvest is by cutting the leaves with scissors rather than tearing or ripping, but care must be taken not to cut all the leaves from one stem as this will hamper and effect its growth.
