Should I cut off parsley flowers?
Also, parsley flowers should be routinely cut back or pinched. If allowed to go to seed, you'll have more parsley than you know what to do with. When you remove the blossoms, the energy the plant was using towards seed production is redirected towards foliage production, which makes the plant grow more vigorously.
For plants like parsley, you can cut the flower stalk off and pinch back the plant to encourage foliage growth. The same goes for basil. Snipping off flowers encourages the basil plant to resume producing leaves, halting further bolting.
Parsley is a biennial, not a perennial. What that means is that it grows into a plant one season, and after winter's cold temperatures, it blooms, sets seeds, and dies. The better idea may be to replant in spring, letting it grow all summer and winter.
By the time the parsley plant has gone to seed or bolted, it's too late. The best idea is to learn how to keep parsley from bolting in the first place, or at least how to slow down the inevitable process. If your parsley plant is bolting, it will likely have not much left in it.
The entire parsley plant, thick stalks included, is edible. When the plant flowers, you can use the flowers in the same way as the leaves. Use the flowers as a garnish or mix them into your pesto, tabbouleh, tzatziki, salsa verde or chimichurri recipe just as you would the leaves.
Parsley plants should be pruned every 2-3 weeks. Since parsley is very resilient, the plant can be pruned heavily. Focus on trimming the long stems of the plant so that they won't block light from shorter stems.
Heat. The heat of summer will trigger parsley to bolt, and if the summer is very warm, the plant is likely to produce flowers earlier than usual. Pinching off the flower buds as soon as they appear can help to lengthen parsley's growing season and give you leaves to harvest for several more weeks.
So how do you care for parsley in the winter? Cut the plants back in the early fall and apply about 2 to 3 inches (5-8 cm.) of mulch around them. The mulch keeps the ground from freezing and thawing in the winter.
Parsley is actually a biennial. This less common classification means that the plant only comes back after two gardening seasons — just enough time to produce leaves, go to seed, and develop a substantial taproot. As a biennial, the parsley plant offers delicious leaves its first year, and goes to seed its second year.
How long does a parsley plant last? Parsley plants will only last for two years before they reach the end of their natural growing cycle. They are a biennial, which means they put on leafy foliage the first year, and then bolt (go to flower and set seed) in the second.
Will parsley reseed itself?
Native to Mediterranean Europe, the parsley plant is a biennial, but is usually grown as an annual in home gardens. After the first year, the leaves tend to become more bitter and tough, but the plant will gladly reseed itself in temperate zones.
Prep your parsley.
You can eat the stems of parsley, but they are much more bitter than the leaves, so I recommend just using the leaves for most recipes. By placing all stems together, you can easily remove them in one quick cut.

Harvest flowering herbs like basil, sage and thyme before their flowers bloom. Once they bloom, the leaves lose their flavor. I prefer to snip off all the flower buds so that the plant lasts longer. Once the plant flowers it will start to make seeds and stop producing leaves.
How often should you harvest parsley? We generally recommend harvesting only up to 30% of a single parsley plant at a time to promote the most vigorous growth. But we've harvested our parsley more heavily than that and been fine, so pinch off stems and leaves as often as you need.
- Refrigerate: Trim the parsley stems, place them in a glass jar or container of water, and store in the refrigerator. Rinse and dry the parsley before use.
- Dry: Pick the leaves off the herbs and arrange them on a paper towel-covered plate. ...
- Freeze: Cut up the herbs and place them in ice cube trays.
Growing Parsley Indoors in Winter
If you don't have a sunny south window, you can grow parsley indoors under fluorescent or LED lights, at least while the plants are small.
If you have ever bought a live pot of herbs from the supermarket, you will have found that you must use all the herbs in a short period, as they often do not last very long sitting on the shelf in your kitchen. There are several reasons for this: Such herbs are not intended to last more than 1-2 weeks.
You can also take cuttings from a friend or neighbour's parsley. Cut a 7cm (2.7 inch) snippet with a few leaves on top and place immediately in a vase of water. Place on a windowsill and in a few weeks the cutting will form a white network of roots. Transfer into soil as soon as you can and grow on.
How many parsley seeds should I plant per hole/cell? Because they can be a little stubborn, it's a good idea to plant 2-3 parsley seeds per hole or cell, and then thin out the extras. But if you're using brand new seeds, you can keep it to one per hole.
Parsley is a biennial that can spread by seed. However, it does not spread aggressively and you can prevent spread by harvesting the herb before it flowers.
Are parsley stems good for anything?
Blend those parsley stems into your next pesto or chimichurri for an added boost of green. Whipping up a leafy salad? Finely chop some cilantro or dill stems for an added, herbaceous crunch. And if you're making a vinaigrette for that salad in a food processor or blender, then throw some herb stems in there, too.
