Basic Growing Parsley From Seed Guide
If you are new to gardening and want to know the basics of how to grow parsley, then here are some tips to get you started:

Starting Parsley from seeds: Parsley seeds can take up to three weeks to germinate.
It is best to start them indoors six to eight weeks before the last expected frost date in your area (Growing Zones).
Once the seedlings have emerged and developed a few true leaves, they can be transplanted outdoors to their final location.

Location: Parsley prefers a partially shaded location. Ideally it should receive at least 4-5 hours of sunlight per day. The location should have a well-draining soil rich in organic matter.
Water requirements: Parsley prefers a moist soil, so make sure to water it regularly to keep the soil consistently moist. Avoid over-watering, as this can lead to root rot.
Heat: As it is cold weather biennial plant, Parsley Bolting may occur early if the plant is subjected to too much stress, such as high heat or being moved to a new location once it has become established.
How to Fertilize: Parsley can benefit from regular fertilization, especially in poorer soils. Use a balanced, all-purpose fertilizer every four to six weeks, during the growing season. Ideally add organic matter to poorer soils prior to transplanting parsley outdoors.
Harvesting regularly: Parsley can be harvested as soon as it has developed several sets of true leaves.
It is best to harvest starting from the outer leaves. This will allow the inner leaves to continue growing.
Regular harvesting will help to promote a bushier growth, and hence make it a more abundant crop.
Pest problems: Parsley is susceptible to pests such as aphids and spider mites. Keep an eye out for any signs of infestation, and treat leaves with insecticidal soap or neem oil.
It is also worth considering to grow parsley companion plants that can help to keep pests away, these include chives, basil, and roses.
By following these basic tips, you can grow healthy parsley plants from seed and enjoy fresh, flavorful herbs all season long.
