Arguably one of the most popular herbs, basil is a tender annual herb native to the southern regions of Europe and Asia. Just as with most herbs, basil thrives in sunny locations that receive at least six to eight hours of light per day. Since this is critical when growing basil, you may wonder, “Does basil like cold weather?” Read on to learn more.
Does Basil Like Cold Weather? Basil is an easy and popular herb to grow, especially common or sweet basil (Ocimum basilicum). This member of the mint family is grown for its sweetly scented leaves used either fresh or dried that compliment a variety of foods. A member of the mint or Lamiaceae family, basil is usually grown as a tender annual. Generally, its growth cycle doesn’t include overwintering; rather it dies down and the hard seeds wait in the ground over winter and then germinate during the spring thaw. When temperatures dip, basil suffers cold damage almost immediately in the form of blackened leaves. Therefore, basil and cold weather do not gibe. If, however, you are the lucky owner of a greenhouse or live in a region where temps may dip but long hours of sun prevail, it is possible to try and over winter your basil baby indoors.
Basil Cold Hardiness The cold tolerance of basil begins to suffer when the mercury drops into the 40’s but really affects the plant at 32 degrees F. (0 C.). The herb may not die, but basil cold damage will be in evidence. Keep in mind the cold tolerance of basil and wait until overnight lows are above 50 degrees F. (10 C.) before setting out transplants. If you set them out prior to temps in the 50’s, you’ll either have to dig them back up or cover them to protect this tender herb from cold snaps. It is also advisable to mulch 2-3 inches of grass clippings, straw, compost or ground up leaves around the basil plants. This will aid in retaining moisture and retarding weeds, but also protect the plant a bit in the event of a sudden, short cold snap. You can also cover the tops of the plants, down to the soil to help trap heat. If the cold snap really drops the mercury, a string of Christmas lights beneath the covered basil plants will help retain some heat under their covering. There may be some minor basil cold damage, but the plants will likely survive.
Basil and Cold Weather Once the mercury falls into the 50’s and it seems that it is likely to continue to dip, make a plan for the basil plants. You may just choose to harvest as many leaves as possible and dry or freeze them. Or, if there is plenty of sunshine during daylight hours and temps are over 50 degrees F. (10 C.) but dip down at night, leave the basil outside during the day and then move it indoors at night. This is a temporary situation and will prolong the life of the plant, but it will eventually expire as temperatures continue to drop. Lastly, you may want to try to get the basil to survive the winter so you will have fresh leaves year round. In this case, you will need to pot the basil and bring it inside. Remember, basil requires lots of light — six to eight hours of direct sun or ten to 12 hours under artificial light. Also, basil is still an annual and as such, it will eventually flower and die, even when brought indoors. That is its life cycle. Additionally, if you do not have the light or space to try and over winter the herb, you can take tip cuttings from the basil and root them in small containers kept on the windowsill. You’ll have to keep an eye on the cuttings, as they tend to grow towards the light and may come in contact with a frosty window, which will result in blackened leaves.

Basil is a sun-loving herb valued for its bright green foliage and distinctive flavor. Although basil is usually easy to get along with, it can develop droopy leaves that can ultimately shorten the life of the plant. Read on to learn more about why your basil is starting to wilt and what can be done about it.
Why Does Basil Wilt? Healthy basil plants require at least eight hours of sunlight every day, well-drained soil, and enough space to allow for plenty of air circulation. If you are meeting the plant’s basic needs and your basil plant keeps falling over anyway, there may be a more serious problem. Fusarium Wilt Basil plant droop that appears suddenly on young plants is often caused by fusarium wilt, a fungal disease that causes stunted growth and droopy, wilted or yellow leaves. The first signs of trouble are decreased growth and leaves with a cupped appearance. Eventually, leaves may drop from the plant. Fusarium wilt is difficult to manage and can remain in the soil for eight to 12 years. If you suspect your plant is infected with fusarium, you’ll probably have to start fresh with a new plant in a completely different location. Prevention is the best solution for fusarium wilt. Purchase healthy, disease-resistant plants. If you plant basil seeds, be sure the package indicates the seeds are fusarium tested.
Root Rot Root rot is another common reason for droopy basil plants. Rot is a water-borne disease generally caused by improper irrigation or poorly drained soil. Let the soil dry slightly between watering, but don’t allow it to become bone dry. If the basil is in a pot, ensure the plant drains thoroughly after watering and never let the pot stand in water. Leaf Spot If your basil plant is starting to wilt and you notice brown, water-soaked spots on the leaves, it may be infected by various fungal diseases known as leaf spot. Remove affected leaves at the first sign of infection. To prevent the disease, water at the base of the plant and never use a sprinkler or spray attachment. If the disease isn’t serious, a fungal spray may help.
Pests Aphids, spider mites and other insects can suck the sap from aphids, which may cause droopy leaves. Most sap-sucking insects are easily removed by spraying the leaves with an insecticidal soap spray. Use the spray strictly according to directions. Never spray the plant when the sun is directly on the foliage, or when temperatures are above 90 degrees F./32 degrees C.

If you’re tempted to toss a handful of fertilizer at your basil plant in hopes of creating a full, healthy plant, stop and think first. You may be doing more harm than good. Basil plant feeding requires a light touch; too much fertilizer may create a big, beautiful plant, but the quality will be badly compromised, as fertilizer decreases the all-important oils that give this herb its distinctive flavor and aroma.
Fertilizing Basil Plants If your soil is rich, your plants may do just fine with no fertilizer at all, or you can dig an inch or two of compost or rotted animal manure into the top 6 to 8 inches at planting time. If you think the plants need a little extra help, you can use a very light application of a dry fertilizer once or twice during the growing season. The best fertilizer for basil is any good quality, balanced fertilizer. If you’re wondering when to feed basil growing in containers, the answer is once every four to six weeks for indoor plants and every two to three weeks for basil in outdoor pots. Instead of a dry fertilizer, use a water-soluble fertilizer mixed at half strength. You can also use an organic fertilizer such as fish emulsion or liquid seaweed. Mix and apply the fertilizer according to label recommendations.
How to Fertilize Basil To feed in-ground basil using a dry fertilizer, sprinkle the fertilizer lightly on the soil around the plants, then scratch the granules into the soil with a spade or garden fork. Be careful not to get the dry fertilizer on the leaves; if you do, rinse it immediately to prevent burning. Water the plant deeply to prevent damage to the roots and to distribute the fertilizer evenly throughout the root zone. For containerized basil plants, simply pour the diluted, water-soluble fertilizer onto the soil at the base of the plant.

Basil is a wonderfully versatile annual herb that is native to southern Asia and the islands of the South Pacific. As with other herbs, basil is easy to grow and with ideal conditions quite prolific. Even so, basil plants can have a number of issues; among these are basil plants with woody stems. If you have basil stems turning into wood, read on to learn about troubleshooting woody stems in basil.
How to Avoid Basil with Woody Stems Basil, Ocimum basilicum, is a member of the Lamiaceae or mint family. Basil is grown primarily for its tender, young leaves which are used either fresh or dried in Asian and European foods. Proper planting and ongoing care of basil gives it the best chance to flourish and avoid disease and pests. Basil, like most herbs, likes lot of sunshine, at least six to eight hours per day. Propagation by seed is simple. You can direct sow into the garden after all danger of frost has passed or start seeds early indoors (six to eight weeks prior to planting outside). Sow the seeds evenly and cover them with ¼-inch of well-drained soil with a pH of 6.0-7.5. Within five to seven days, you’ll see the seedlings begin to emerge. Keep the seedlings moist but not drenched or they may develop a fungal disease called damping-off. When the seedlings have two or three pairs of leaves, thin them or transplant them 6-12 inches apart. Mulch around the plants with grass clippings, straw, compost or ground leaves to help retain moisture and retard weeds.
Water the basil every seven to 10 days, depending upon rainfall. If the plants are in containers, they may need additional water. Lightly fertilize basil with a 5-10-5 food once or twice at the rate of 3 ounces for every 10 feet of planting space. Use a liquid fertilizer at half the recommended strength every four to six weeks for indoor basil and every three to four weeks for basil that is grown outside in containers. Follow all of the above and you should have an abundance of lovely, aromatic basil leaves to harvest. But what happens if you start getting woody basil plants?
Troubleshooting Woody Stems in Basil Basil, unlike some plants, actually loves to have a little taken off the top. You can harvest as soon as the plant is a few inches tall. Snip young leaves or, if you are harvesting an entire stem, cut above a pair of leaves. This encourages new growth at the cut which should be visible within a week. Keep trimming the basil throughout the growing season to encourage growth. If you can’t use the basil immediately, hang stems to dry or freeze the basil in ice cube trays for later use. Puree the basil with either a little water or olive oil, put the puree in the tray, freeze, and then pop them out and store the cubes in the freezer in an airtight container for later use. The important thing is to keep pruning your basil. If you don’t, the plant will flower and form seed which, in turn, causes the stems to become woody. The leaves will turn bitter as well. If you’re growing the basil as an ornamental for its attractive foliage and flowers, then you probably don’t care if the basil stems are turning into wood. If, however, you love those succulent young leaves, keep snipping. Old stems that have not been cut back also turn woody just as a plant that has been allowed to flower. Do keep in mind that basil is an annual. You can extend its life a bit by bringing the plant inside when the weather begins to get cold, but it will eventually die. Woody basil plants simply mean that the plant is protecting itself from the dipping temps. If you bring it inside, give it plenty of light. Production will slow in the winter, but you should still be able to harvest some delectable fresh basil leaves to enliven your winter meals.

Versatile and easy to grow, basil is an attractive culinary herb valued for its aromatic leaves, which are used either dry or fresh. Although basil is usually grown as an annual, it is suitable for growing year round in USDA plant hardiness zones 10 and above. Although the herb is relatively trouble-free, it is susceptible to certain pests and diseases that can cause yellowish leaves on basil plants.
What Causes Basil Leaves to Turn Yellow? There are a number of reasons for a basil plant turning yellow, and determining the reason isn’t always easy. Improper watering – Root rot, a result of too much water, is one of the most common reasons for yellow leaves on basil plants. Water basil only when the top 1 to 2 inches of soil is dry, and remember that slightly dry soil is healthier than soggy soil. As a general rule, one deep watering every seven to 10 days is adequate. If you grow basil in a container, be sure the pot has at least one drainage hole. Fungal disease – Although several fungal diseases can cause yellow leaves on basil plants, downy mildew is one of the most common. Downy mildew is a fast-spreading fungus recognized by yellowish basil leaves and a fuzzy, gray or brown growth. If you catch the problem early, you may be able to stop the spread by clipping affected growth. However, badly affected plants should be removed and disposed of carefully.
Growing conditions – Chilly temperatures are another reason for yellowish basil leaves. Basil prefers daytime temps above 70 F. (21 C.). Nighttime temperatures should be above 50 F. (10 C.) Lack of sun is yet another common cause of yellowish basil leaves. Basil prefers bright sunlight for six to eight hours per day. Basil grown indoors will likely need artificial light during the winter, ideally for 10 to 12 hours per day. Aphids – Aphids are tiny pests that suck the juice from tender foliage, thus causing yellow leaves on basil plants. Look for aphids on the undersides of leaves and on the joints of stems and leaves. Aphids are easy to control with insecticidal soap, but be careful not to apply the soap when the sun is directly on the leaves or on hot days, as the soap can scorch the plant.
Root knot nematodes – These small, soil-dwelling pests can cause yellowish basil leaves and small galls on the roots. The best recourse is to harvest the plant and use the healthy leaves. Next time, plant resistant varieties in soil not affected by nematodes. Lack of nutrients – Basil is a hardy plant that does well in poor soil, but it still requires nutrients in order to thrive. Fertilize basil regularly to prevent yellowish basil leaves, using an all-purpose balanced fertilizer.

Help! My basil leaves are curling and I don’t know what to do! Why do basil leaves curl under? The reason for basil leaves curling up may be environmental, or your plant may be diseased or pestered by pests. Read on to learn more about this frustrating problem.
Reasons for Basil Leaves Curling Up Generally, growing basil in the garden is easy and stress free. That being said, problems can and do happen. Basil leaf curl treatment is dependent on the specific factor causing it. Here are the most common stressors leading to curling basil leaves. Sunlight – Basil is definitely a sun-loving plant and exposure to less than six hours of bright light per day may result in distorted foliage or basil leaves small and curled. Relocating the plant to a sunnier location may solve the problem. Water: Too much or too little – Basil requires regular water, but not too much. As a general rule, water the plant deeply whenever the top 1 to 2 inches of soil feels dry to the touch, usually once every four to seven days. However, keep in mind that potted plants may require more frequent irrigation, especially during hot, dry weather.
Whether the plant is in the ground or in a container, be sure the soil (or potting mix) is lightweight and drains well. Water at the base of the plant and keep the leaves as dry as possible. Diseases – Fungal diseases may be the cause of basil leaves curling up, but chances are, you’ll notice other telltale signs. For example, powdery mildew is a fungal disease that causes a grey, powdery substance on the leaves. The disease is caused when conditions become too moist, including too much shade or soggy soil. Fusarium wilt, which is usually deadly, can cause brown or distorted leaves. To prevent moisture related diseases, water basil carefully as directed above. Pests – Basil is a hardy plant, but it can sometimes be bothered by aphids and other small, sap-sucking pests such as spider mites or scale. The pests can be difficult to see, but a close look at the leaves, especially the undersides, will usually tell the tale.
If you determine your plant is infested with bugs, insecticidal soap spray usually keeps the pests in check. Be sure to spray when the foliage is in the shade; otherwise, the spray may scorch the plant. Don’t spray when the temperatures are above 90 degrees F. (32 C.).

Basil is the “king of herbs,” a plant that has been used in both food and for medicinal purposes for thousands of years. It’s rich and varied flavors and delightful smell have continued to make it a popular garden and potted plant. Of the many varieties you can choose for your garden, bush basil plants are compact and showy and have smaller leaves than sweet basil with a concentrated punch of flavor.
What is Bush Basil? Basil comes in so many varieties that it can be hard to choose just one or two for a limited space. Sweet basil (Ocimum basilicum) is fairly common, a tall herb with large, glossy green leaves. Bush basil (Ocimum minimum), sometimes called dwarf basil, only grows to about six inches tall (15 cm.) and is compact and bushy with smaller leaves. While both are annual plants, bush basil may survive the winter in milder climates. For culinary purposes, bush basil vs. sweet basil is a matter of taste. The leaves of both plants are used in similar ways, like in sauces or in salads. The flavor in the leaves of bush basil is more intense than sweet basil, so you get more bang for your buck. Because of this strong flavor, you’ll often see bush basil called “spicy globe” basil.
Growing Bush Basil in the Garden or Containers Bush basil care is simple, making this tasty and fragrant plant easy to grow even for those without a green thumb. Because it’s shrub-like, compact, and bushy, growing bush basil in a pot is a great choice. It can even be used to create a low hedge in a garden. It will grow well and easily whether you choose a container or you put it right in the ground. Bush basil prefers rich soil, so find a good quality potting soil, or use a fertilizer to enrich your soil. Choose a full-sun location that drains well, water your plant regularly, and it should grow well. As it grows, harvest leaves as needed. Pinching it back will actually help it grow more. If you see flowers starting to grow, pinch them off. A flowering basil plant loses its flavor.
How to Use Bush Basil Plants The leaves of the bush basil have an intense flavor, so you don’t need to use as many as you would with other varieties. Otherwise, you can use your small leaves exactly as you would with sweet basil. Bush basil leaves go great in anything Italian, like pasta dishes and tomato sauces. You can use the leaves in salads and with vegetable dishes. Basil even tastes great in drinks, like lemonade, iced tea, and cocktails. Bush basil plants are easy to grow, the leaves taste great, and they look nice both in containers and gardens. They make a great choice for any garden, yard, or windowsill.

A member of the sunflower family, arnica (Arnica spp.) is a perennial herb that produces yellow-orange, daisy-like blooms in late spring and early summer. Also known as mountain tobacco, leopard’s bane and wolfbane, arnica is highly valued for its herbal qualities. However, before you decide to grow arnica or use the herb medicinally, there are a number of things you should know.
Arnica Herb Uses What is arnica herb for? Arnica has been used medicinally for hundreds of years. Today, the roots and flowers are used in topical treatments such salves, liniments, ointments, tinctures and creams that soothe tired muscles, relieve bruises and sprains, ease the itch of insect bites, soothe burns and minor wounds, promote hair growth and reduce inflammation. Although the herb is usually applied topically, homeopathic remedies with highly diluted amounts of the herb are available in pill form. Arnica is generally safe when used topically, although products containing arnica should never be used on broken skin. However, arnica should never be taken internally except when the doses are small and extremely diluted (and with the guidance of a professional). The plant contains a number of toxins that can cause a variety of potentially dangerous results, including dizziness, vomiting, internal bleeding and heart irregularities. Ingesting large amounts can be deadly.
Arnica Growing Conditions Arnica is a hardy plant suitable for growing in USDA plant hardiness zones 4 through 9. The plant tolerates nearly any well-drained soil, but generally prefers sandy, slightly alkaline soil. Full sunlight is best, although the arnica benefits from a bit of afternoon shade in hot climates. How to Grow Arnica Planting arnica isn’t difficult. Just sprinkle the seeds lightly on prepared soil in late summer, then cover them lightly with sand or fine soil. Keep the soil slightly moist until the seeds germinate. Be patient; seeds usually sprout in about a month, but germination can take much longer. Thin the seedlings to allow about 12 inches between each plant. You can also start arnica seeds indoors. Plant the seeds in pots and keep them in bright, indirect sunlight where temperatures are maintained at approximately 55 F. (13 C.) For best results, grow the plants indoors for several months before moving them to a permanent outdoor location after all danger has passed in spring. If you have access to established plants, you can propagate arnica by cuttings or divisions in spring.
Arnica Plant Care Established arnica plants require very little attention. The primary consideration is regular irrigation, as arnica is not a drought-tolerant plant. Water often enough to keep the soil lightly moist; don’t allow the soil to become bone dry or soggy. As a general rule, water when the top of the soil feels slightly dry. Remove wilted flowers to encourage continued blooming throughout the season. Disclaimer: The contents of this article is for educational and gardening purposes only.
