How does parsley grow in cold climates?
Parsley (Petroselinum crispum) is a popular herb grown in many parts of the world. It is considered one of the hardier herbs, tolerating temperatures down to about 25°F (-4°C) for short periods.
In cold climates, parsley can often survive winter temperatures with protection provided by a thick layer of mulch and an appropriate low tunnel structure, such as a cold frame or hoop house, to keep out heavy snow and wind.
For this reason, it can be planted early in the season before other finicky herbs, such as basil and thyme, are ready to go into the ground.
When grown in adequate soil with regular watering, parsley requires little maintenance other than occasional fertilization at the beginning of its growing season.
If planted early enough in the season before severe cold weather sets in, parsley may continue to produce leaves until a hard frost when it will go dormant for winter. Still, it will reappear again when warming temperatures arrive come springtime.
This biennial herb should be allowed to flower and go to seed in its second year to resect itself naturally, creating plentiful parsley harvests for your kitchen!

Parsley’s Ability to Handle Frost
Parsley is a versatile herb that can grow in various temperatures, from warm climates to cold. This makes it a popular choice for gardeners, as it is easy to grow and thrive in most conditions.
One of the questions often asked about parsley is whether it can handle frost. This article will discuss the effects of frost on parsley and how you can use it successfully in your garden.
How cold can parsley tolerate?
Parsley is a hardy biennial that can handle cold weather, but frost could be the end of it. For parsley to survive even the lightest frost, it needs to be grown in well-drained soil and mulched with a four to a five-inch layer of straw.
Parsley is not entirely fussy when it comes to cold, though ideal temperatures of 45-75 degrees F are recommended for growing.
While some varietals can tolerate temperatures down to 25 degrees F without being damaged, they won’t thrive under such chilly conditions. It’s also important to note that young seedlings may be more susceptible than mature plants.
In terms of hardiness zones, parsley will successfully overwinter in zones 8-10 without extra protection. For colder climates, insulating your parsley over the winter with straw and plastic covers will give them their best chance against below-freezing temperatures.
You may even want to consider planting parsley in containers or pots and bringing them inside as an extra precaution against frost or prolonged exposure to cold weather.
What are the signs of frost damage?
When exposed to frost, parsley is one of the less cold-tolerant plants. Although it has some frost tolerance, it is not considered a frost-hardy plant and may suffer damage when freezing temperatures occur.
It is essential to recognize the signs of frost damage on your parsley crop to protect it from further damage.
The leading indicator of frost damage on parsley is wilted leaves, which often appear limp and discolored.
It is also possible for the stems and leaves to blacken or take on a reddish color if they are exposed to a severe drop in temperature overnight or over several hours during the day.
Discoloration may spread from light yellow or green spots to a brownish-green tinge that surrounds entire leaves, stems, and flowers.
Other signs that your parsley has been affected by frost include:
- Fragmented leaf tips
- Curling of both newly emerged leaves and older foliage
- Stunted growth, if exposed to cold weather, persists over several days or weeks
- Difficulty in identifying healthy tissue amidst damaged parts of the plant
However, once warmer weather returns, you will likely be able to tell if your parsley has been affected by frost. Most new growth should recover quickly after temperatures rise again.

What can be done to protect parsley from frost?
Parsley is a hardy herb that is considered cold-tolerant—it can survive temperatures as low as 20°F (-7°C)—but when exposed to extended periods of frost and sub-freezing temperatures, it will die back.
It also may become damaged by multiple cycles of freezing and thawing. Fortunately, if given the right conditions, parsley can recover even after severe cold exposure.
The most important way to protect parsley from frost is to provide adequate protection through proper planting techniques, mulching, and insulating structures like walls and fences, helping to prevent the wind from damaging the plants.
Additionally, keeping parsley in a warm location away from harsh winds during autumn will help prevent frosts from forming too quickly or severely damaging leaves.
Mulching your parsley plants with hay or straw will help protect them not only against extended frost but also keep the soil temperature consistently warm throughout colder seasons.
Like mulching, row covers are another excellent method for protecting parsley—they provide insulation for roots and give much-needed warmth that helps keep plants healthy during colder months.
For containerized plants, bring them indoors when temperatures drop below 20°F (-7°C). If left outside in containers when the temperature drops too low, they may become damaged beyond repair.
Tips for Growing Parsley in Cold Climates
Parsley is an herb often found in Mediterranean dishes. It is a hardy plant that can handle cold weather, exposed gradually.
Growing parsley in climates with cold or even frosty temperatures can be done with a few simple tips and tricks. In this article, we’ll discuss these tips and how you can grow parsley in colder climates:
Choose the right variety
When shopping for parsley for cold climates, look for varieties that produce flat-leaved stalks instead of curly leaves. These types are generally more complex and more likely to survive frostbite.
Additionally, taller varieties may be better suited for cold climates and should have dark green leaves to inject intense flavor into your dishes.
Some examples of good choices include:
- Moss Curled
- Giant of Italy
- Plain-leaved Parsley
Please pay attention to the information on the packet label; it will indicate whether the specific variety can handle colder weather.
In addition to the variety you select, remember that soil pH levels play an essential role in whether parsley can withstand frost; soil rich in lime will help protect growth from topical frost injury.
Plant in a sheltered location
When growing parsley in colder climates, selecting a sheltered spot is best to protect your plants from the elements.
Choose a location that gets plenty of light and features well-draining soil with an alkaline pH, but make sure the spot is protected from harsh winds.
If you’re planting parsley in a container or planter, consider setting it up on a patio where it won’t be exposed to cold drafts and strong winds.
The location should also be relatively close to the house – any more than 300 feet away, and the temperature will likely drop too much for the plant to survive winter temperatures.
Parsley can typically handle light frosts if planted early enough; however, harsh frost can damage your crops. Cover your plants with burlap, blankets, or other materials before nighttime when frosts are predicted.
You may want to use an indoor growing option such as hydroponics if you face frequent frosts or severe weather conditions outdoors.
Mulch heavily
Mulching heavily can help protect parsley in cold climates. Well-rotted organic materials, such as compost, aged manure, grass clippings, and shredded leaves, make excellent mulching materials because they are lightweight and help retain heat.
In addition to protecting parsley from frost, a thick layer of mulch helps insulate the root system against shallow temperatures. It also helps the soil retain moisture without becoming waterlogged.
Mulch can also help prevent weeds from competing with your parsley plants for soil moisture and nutrients.
When applying mulch, ensure it extends out several inches beyond the edges of the plant’s foliage so it’s impossible to damage it when gardening or cultivating mistakenly.
If you have garden pests in your area, use a thicker layer of material and apply directly onto the soil surface around each plant for extra protection against cold weather and critters!
Conclusion: Can Parsley Handle Frost?
After exploring all the facts, it is evident that parsley can handle frost. It is a cold-tolerant plant with temperatures down to 28°F in the right conditions. This makes it the perfect herb for cooler climates.
Parsley is an easy-to-grow herb with a wide variety of culinary, medicinal, and ornamental uses. With proper care and maintenance, parsley can provide an abundance of tasty leaves and flowers for months.
Summary of key points
In conclusion, parsley is a biennial or short-lived perennial herb widely used worldwide as a garnish and flavoring agent. It has a mild flavor, with the flat-leafed variety being more commonly used in cooking due to its more robust flavor.
Although parsley can survive light frosts, it can be damaged by heavy frost and extended subfreezing temperatures.
Therefore, if planted outside during the spring season in northern zones, it may not survive the onset of deep winter temperatures.
In this case, it is wise to protect plants from the cold through the use of mulching or other forms of insulation – or by growing parsley indoors where you can control temperature variables.
Final thoughts on parsley and frost
Parsley is an incredibly hardy plant that will survive various temperatures, making it an ideal choice for home gardens in temperate and cool climates.
When cultivating parsley in your garden or flower beds, it is essential to remember that some varieties are more resilient in cold weather than others. Choosing a variety that is incredibly tolerant of low temperatures may be wise if you live in a more relaxed area.
When exposed to cold temperatures, parsley will become brown and wilted-looking but can survive frost up to around -4°F (-20°C).
Light snow or frost will not irreversibly damage the plant if you provide adequate protection during severe cold spells. The best practice is to keep the parsley covered with a blanket or other insulating material until the cold passes.
Parsley has advantages and disadvantages when it comes to low temperatures and frost. While it can handle light snowfall, it should not be expected to cope with brutal winters without protection.
However, its resilient nature means it should remain healthy throughout milder winter periods and thrive through warmer months when grown in nutrient-rich soils and watered regularly.
