When it comes to gardening, many of us think of flowers and vegetables as the primary outdoor plants. However, herbs can also be a wonderful addition to any outdoor space, providing fresh flavor and fragrance to a variety of dishes. In this article, we’ll explore the world of outdoor herbs, discussing which varieties can be kept outside, how to care for them, and the benefits they can bring to your garden and your cooking.
Choosing the Right Herbs for Outdoor Growth
Not all herbs are created equal when it comes to outdoor growth. Some varieties are more sensitive to temperature, humidity, and light, and may require protection or special care to thrive. On the other hand, some herbs are perfectly suited to outdoor growth, and can even benefit from the extra space and sunlight. When selecting herbs to keep outside, consider the following factors:
Climate and Hardiness
Different herbs have different hardiness levels, which determine their ability to withstand cold temperatures, heat, and other environmental stressors. Herbs like rosemary, thyme, and oregano are relatively hardy and can tolerate light frosts, while basil, lemongrass, and mint are more sensitive and may require protection during colder months. Be sure to choose herbs that are suitable for your local climate and can thrive in the conditions you can provide.
Light and Temperature Requirements
Herbs also have varying light and temperature requirements. Some, like chamomile and lavender, prefer full sun and well-drained soil, while others, like parsley and dill, prefer partial shade and more moist conditions. Consider the amount of sunlight and shade your outdoor space receives, as well as the temperature fluctuations, when selecting herbs to keep outside.
Caring for Outdoor Herbs
Once you’ve selected the right herbs for your outdoor space, proper care is essential to ensure they thrive. Here are some tips for caring for your outdoor herbs:
Soil and Watering
Herbs require well-drained soil that is rich in organic matter. Add compost or manure to your soil to improve its fertility and drainage. Water your herbs regularly, but avoid overwatering, which can lead to root rot and other problems. Most herbs prefer about 1-2 inches of water per week, either from rain or irrigation.
Pruning and Maintenance
Regular pruning is essential for keeping your outdoor herbs healthy and productive. Prune back leggy stems, pinch off flower buds, and trim back overgrown plants to encourage new growth. This will also help prevent your herbs from becoming too woody or developing seeds, which can reduce their flavor and aroma.
Popular Outdoor Herbs
So, which herbs can be kept outside? Here are some popular varieties that thrive in outdoor conditions:
- Rosemary: A fragrant, evergreen herb that prefers full sun and well-drained soil.
- Thyme: A low-growing, spreading herb that tolerates light frosts and prefers partial shade.

Benefits of Keeping Herbs Outside
Keeping herbs outside can have numerous benefits, from improving air quality to attracting beneficial insects. Here are just a few reasons why you should consider keeping herbs outside:
Pest Control and Pollination
Many herbs, like basil and mint, have natural pest-repelling properties that can help keep unwanted insects away from your garden. Others, like chamomile and lavender, attract beneficial insects like bees and butterflies, which can help pollinate your plants.
Improved Air Quality
Some herbs, like rosemary and thyme, have been shown to improve air quality by removing pollutants and toxins from the air. This can be especially beneficial in urban areas, where air quality can be poor.
Aesthetic Appeal
Outdoor herbs can also add visual interest to your garden, with their varied textures, colors, and shapes. Many herbs, like rosemary and lavender, have attractive flowers or foliage that can add beauty to your outdoor space.
Conclusion
Keeping herbs outside can be a wonderful way to add fresh flavor and fragrance to your cooking, while also improving the health and beauty of your garden. By choosing the right herbs for your climate and outdoor space, and providing proper care and maintenance, you can enjoy a thriving and productive herb garden all year round. Whether you’re a seasoned gardener or just starting out, we hope this guide has inspired you to get outside and start growing your own outdoor herbs. With their many benefits and versatility, outdoor herbs are sure to become a favorite part of your garden and your cooking routine.
What are the benefits of growing herbs outdoors?
Growing herbs outdoors offers several benefits, including increased space, better air circulation, and more natural sunlight. When herbs are given the room to spread out, they tend to grow more vigorously and produce more foliage, which can be harvested and used in cooking. Additionally, outdoor herbs are often less prone to pests and diseases that can be prevalent in indoor environments, such as spider mites and root rot. This is because outdoor herbs are exposed to natural predators and beneficial insects that can help to keep pest populations under control.
Another benefit of growing herbs outdoors is that it allows for a greater variety of herbs to be grown. Some herbs, such as rosemary and lavender, are naturally adapted to outdoor environments and can thrive in conditions that would be difficult to replicate indoors. By growing these herbs outdoors, gardeners can enjoy a wider range of flavors and aromas in their cooking, and can also use the herbs to add beauty and fragrance to their outdoor spaces. Overall, growing herbs outdoors can be a rewarding and enjoyable experience that offers many benefits for gardeners and cooks alike.
How do I choose the right location for my outdoor herb garden?
When choosing a location for an outdoor herb garden, there are several factors to consider. The first is sunlight: most herbs require at least four to six hours of direct sunlight per day, so a location that receives full sun to partial shade is ideal. The next factor to consider is soil quality: herbs prefer well-draining soil that is rich in organic matter, so a location with good soil structure and fertility is essential. Additionally, gardeners should consider the proximity of the herb garden to a water source, as well as the potential for wind or frost damage.
In terms of specific locations, a spot near a kitchen door or patio can be ideal for an outdoor herb garden, as it allows for easy access and harvesting. Another option is to create a container garden on a deck or balcony, which can provide a convenient and space-saving way to grow a variety of herbs. Regardless of the location, gardeners should ensure that the soil is properly prepared and that the herbs are planted at the same depth and spacing as they were in their pots. With proper care and attention, an outdoor herb garden can thrive in a wide range of locations, providing fresh flavors and aromas for months to come.
What are some low-maintenance herbs that can thrive outdoors?
Some low-maintenance herbs that can thrive outdoors include rosemary, thyme, and oregano. These herbs are naturally adapted to outdoor environments and can tolerate a range of conditions, including drought, heat, and cold. They are also relatively pest- and disease-free, which makes them ideal for gardeners who are new to growing herbs or who want to minimize their maintenance requirements. Another low-maintenance herb is sage, which is a hardy perennial that can survive winter temperatures and require minimal care.
In addition to these herbs, there are several other low-maintenance options that can thrive outdoors, including mint, chamomile, and lemon balm. These herbs are often vigorous growers that can spread quickly, so they may require occasional pruning to keep them under control. However, they are generally easy to care for and can provide a range of flavors and aromas for cooking and other uses. By choosing low-maintenance herbs, gardeners can enjoy the benefits of an outdoor herb garden without requiring a lot of time or effort to keep their plants healthy and thriving.
How often should I water my outdoor herb garden?
The frequency of watering an outdoor herb garden depends on several factors, including the type of herbs being grown, the climate and weather conditions, and the soil quality. As a general rule, herbs prefer moist but well-draining soil, so they should be watered regularly but not excessively. In hot and dry weather, herbs may require daily watering, while in cooler and more humid weather, they may only need to be watered every few days. It’s also important to avoid overwatering, which can lead to root rot and other problems.
In terms of specific watering schedules, gardeners can water their outdoor herb garden in the morning or early afternoon, when the sun is not too intense. This allows the plants to absorb the water throughout the day, and can help to prevent evaporation and runoff. It’s also a good idea to check the soil moisture by sticking a finger into the soil up to the knuckle, and to adjust the watering schedule accordingly. By watering their outdoor herb garden regularly and appropriately, gardeners can help to promote healthy growth and prevent problems such as drought stress and root rot.
Can I grow herbs in containers outdoors?
Yes, herbs can be grown in containers outdoors, which can provide a convenient and space-saving way to enjoy fresh flavors and aromas. Container gardens can be placed on a deck, patio, or balcony, and can be moved to different locations to take advantage of sunlight and other environmental conditions. When growing herbs in containers outdoors, it’s essential to choose a container that is at least 6-8 inches deep and has good drainage holes to prevent waterlogged soil.
In terms of care, herbs grown in containers outdoors require similar conditions to those grown in the ground, including adequate sunlight, water, and fertilization. However, they may require more frequent watering, as the soil in containers can dry out quickly. It’s also important to choose a well-draining potting mix and to fertilize the herbs regularly to promote healthy growth. By following these tips, gardeners can enjoy a thriving and productive container herb garden outdoors, even in small or limited spaces.
How can I protect my outdoor herb garden from pests and diseases?
There are several ways to protect an outdoor herb garden from pests and diseases, including using physical barriers, practicing good hygiene, and applying organic or integrated pest management (IPM) techniques. Physical barriers, such as fine mesh or fine-netted row covers, can help to keep pests such as whiteflies and aphids away from the herbs. Good hygiene practices, such as removing weeds and debris, can help to prevent the spread of diseases such as fungal infections and root rot.
In addition to these methods, gardeners can use organic or IPM techniques to control pests and diseases in their outdoor herb garden. For example, neem oil or insecticidal soap can be used to control pests, while copper-based fungicides or bicarbonate solutions can be used to control fungal diseases. It’s also important to monitor the herb garden regularly for signs of pests or diseases, and to take action quickly to prevent problems from getting out of control. By using a combination of these methods, gardeners can help to protect their outdoor herb garden from pests and diseases, and enjoy a healthy and productive harvest.
Can I grow herbs outdoors year-round in cold climates?
In cold climates, it can be challenging to grow herbs outdoors year-round, as many herbs are sensitive to frost and freezing temperatures. However, there are several ways to extend the growing season and enjoy fresh herbs outdoors, even in cold climates. One option is to use cold frames or hoop houses, which can provide protection from frost and freezing temperatures. Another option is to grow herbs in containers that can be moved indoors during the winter months, or to use a greenhouse or indoor growing system.
In terms of specific herbs, some varieties are more cold-hardy than others and can be grown outdoors year-round in cold climates. For example, herbs such as rosemary, thyme, and sage are relatively hardy and can survive light frosts, while herbs such as mint and lemon balm can be grown outdoors in cold climates with proper protection. By using a combination of these methods and choosing cold-hardy herb varieties, gardeners can enjoy a year-round outdoor herb garden, even in cold climates. This can provide a range of flavors and aromas for cooking, as well as a beautiful and fragrant addition to the outdoor landscape.
