Rosemary is a popular herb that can be used in the home, but it’s also an attractive ornamental plant. Unfortunately, rosemary doesn’t always do well in cold climates. If you live in an area where temperatures drop below freezing, you may wonder if your rosemary will survive the winter.
Can Rosemary Survive Frost?
Rosemary is a perennial herb that can tolerate low temperatures and grows well in USDA zones 8-10. But this fragrant herb does not fare well in cold weather, which means it won’t survive a hard frost. However, if your rosemary plants are growing under warm conditions (around 70 F), they will survive light frosts and even snowfalls.
If you’re trying to grow rosemary outside of the plant’s preferred climate range (zones 8-10), you’ll want to take special care with your plantings so that they don’t get damaged by temperatures below freezing. Most of the time this involves either bringing them indoors or covering them with heavy blankets at night while they sleep through the winter months when freezes may occur!
How Tolerant Is Rosemary To Cold Weather
You may have noticed that rosemary can survive temperatures as low as -10 degrees, but what if you live in a colder climate?
Rosemary is very tolerant of cold weather. The plant will withstand temperatures down to -20 degrees Fahrenheit and frost that isn’t too severe. If you live in an area where the temperatures drop below freezing, your rosemary plants will be fine as long as they are protected from wind and don’t experience repeated subzero exposure over a period of time.
If your rosemary plants do get frozen solid, here’s what you should do: First, thaw out the plant in a warm room (such as near some heat vents) so you don’t damage or kill it. Then place it back outside once it’s warmed up again (but not during freezing conditions). Once everything is thawed out, give the plant some water to rehydrate its roots before placing them back outside for good!
How To Protect Your Rosemary From Frost
Did you know that rosemary can survive frost? It’s true! Here are some tips for protecting your rosemary from freezing temperatures:
- Cover the plant with a blanket or sheet. This is the easiest way to protect plants in your yard or garden from frost. You can also use a tarp or plastic sheeting if you don’t have any blankets lying around. Just be sure to remove it once the danger of frost has passed, as too much moisture could damage your plant over time.
- Plant rosemary in a container. If you don’t want to cover up your rosemary, consider planting it in an attractive pot instead—this will help keep its roots protected when temperatures drop below 50 degrees Fahrenheit (10 degrees Celsius).
- Plant rosemary in a protected area of your yard. If you live where winters tend not to get very cold but still want protection from frosts and freezes, choose a spot close enough so that when temperatures dip down into freezing territory overnight during the winter months they won’t affect your plant too much! Ideally, this should be somewhere out of direct sunlight exposure since direct sunlight exposure can cause stress on many kinds of plants including roses which may already suffer from heat stress if left outside during summertime months without adequate water/irrigation practices established beforehand.
Caring For Rosemary During The Winter
If you live in a cold climate, your rosemary may not survive the winter. However, if you’re able to overwinter it indoors as a houseplant, it will continue to thrive for years to come.
Rosemary is a perennial herb that can be grown from seed or cuttings. If you purchase your rosemary plant at the grocery store or farmers’ market, it will have been propagated from seeds by a farmer or grower who knows what they’re doing and can make sure that the plant will do well in your area (which means knowing how much sun and water it needs). Most likely this means that whatever variety of rosemary you buy will be hardy enough to live through any season without needing special care other than watering once every few weeks.
There are many different varieties of rosemaries: some have small leaves while others are larger; some look like trailing plants while others grow upright; some produce flowers while others do not. But regardless of these differences among breeds, all types require full sun exposure during the day and need regular watering; otherwise, they’ll become stressed out and die back quickly before ever having time to flower!

What temperatures will kill rosemary?
For rosemary, the most important thing to know is that it can endure temperatures as low as -10 degrees F. The plants will survive an average winter in most of North America without any problems! However, when temperatures dip below -20 degrees F, your rosemary may be damaged or killed.
Can I overwinter rosemary?
Rosemary is a perennial herb that should be brought indoors before the first frost. It can also be grown in a container and overwintered inside, but this will limit its ultimate size and vigor.
In general, it’s not recommended to try overwintering rosemary since it will likely die back completely during winter. However, if you choose to try it anyway or grow your rosemary as an annual outdoors (which is sometimes done), keep these tips in mind:
- Rosemary should be planted in full sun with good drainage.
- Water weekly throughout summer until established; then water regularly until flower buds form.
- Prune off dead stems as needed after flowering begins in spring; once new growth has begun you may prune again right before bringing them indoors for winter storage—but no sooner!
Conclusion
Rosemary is an easy plant to care for, but it does require some special care during the winter. If you’re hoping to overwinter your rosemary plants, there are a few things you need to keep in mind. First, don’t over-water them! This will cause them to rot faster when exposed to cold temperatures and ice crystals on top of their soil surface. Second, make sure there are no gaps where air can get into the soil around their roots which could also result in damage due to freezing temperatures. Lastly (and perhaps most importantly), provide good drainage so they don’t become waterlogged during spring thaw periods.
