Basil has long been a favorite of gardeners and food enthusiasts alike, thanks to its rich flavor and remarkable versatility in both the garden and the kitchen.
Even those without a dedicated vegetable plot often make space for a few basil plants due to its reputation for enhancing flower beds, attracting pollinators, and providing delightful aromatherapy to any terrace or patio.
Cooks consider this luscious herb irreplaceable, and foodies insist that no tomato dish is complete without it. However, growing basil successfully requires a bit of attention and care.
It’s essential to create optimal growing conditions and provide proper maintenance throughout the growing season to prevent disease and ensure the plants produce well. But with careful selection of the suitable variety and diligent care, growing basil can be a rewarding experience that yields flavorful, aromatic results.
Selecting basil varieties for your garden
When selecting basil varieties for your garden, it’s essential to consider both their flavor and visual appeal. Basil comes in an impressive array of colors, shapes, and sizes, so choosing the right type for your needs is essential to ensure a productive and ornamental harvest.
There are four main categories of basil to consider: sweet basils, small-leaved or dwarf basils, purple-leaved basils, and scented-leaved basils. Sweet basils, such as the famous ‘Genovese’ and ‘Napoletano’ varieties, are large-leaved and tender with a rich, aromatic flavor.
These are the classic Italian basils and are perfect for making pesto. They are slower to flower than other types and can reach heights and widths of 16 to 24 inches.
Dwarf basils, on the other hand, are compact and generally stay under a foot tall and wide. While they are quick to flower, their neat habit makes them an excellent choice for edging garden beds or softening container plantings. They have a spicy flavor with hints of anise and clove, and you can harvest entire branches to sprinkle over salads or hors d’oeuvres.
Purple basils are less commonly used in cooking but are highly ornamental and add a long season of beauty to any garden. They are typically the same size as sweet basils and come in deep purple or burgundy shades.
Scented-leaved basils offer an extra dimension of flavor, with varieties like lemon, lime, and cinnamon adding unique and exciting flavors to sweet and savory dishes.
These basils can be sown thickly, like microgreens, and can be harvested for culinary and ornamental use. With the proper selection and care, your basil plants can be productive and visually stunning.
Creating the perfect environment for basil
Creating the perfect environment for basil to thrive is essential for a productive and healthy plant. Since basil is native to warmer climates, maintaining warm temperatures is critical to its growth. Any exposure to temperatures below 50°F can lead to stunted growth, while optimal temperatures range from 60°F to 80°F.
Starting basil seeds indoors or in a greenhouse provides ideal growing conditions, and germination typically occurs within six days in a soilless mix of peat, vermiculite, and perlite. Once the plants are 7-8 weeks old and firmly rooted, they can be transplanted into the garden after the last frost date.
To promote a more robust and bushier plant, pinch the central growth tip down to two sets of leaves. Take your time when transplanting, as rushing the process can lead to poor growth and susceptibility to pests and disease. Basil thrives in fertile, well-drained soil, so keeping the soil moist and consistent is essential.
Mulching can help maintain even moisture, but wait until the soil has warmed to 70°F to avoid any fungal problems. Basil also benefits from a warm, protected spot and some afternoon shade if planted in a windy, quickly drying area.
Location and spacing for growing healthy basil
Location and spacing are crucial factors in growing healthy basil. Each plant should be given ample room to spread out, ideally at least a square foot of bed space, allowing air to circulate freely around all sides. With high humidity and overwatering being the enemies of basil, it’s essential to avoid overhead watering that can promote fungal diseases.
Additionally, rotating the basil crop each year, rather than planting it repeatedly in the same spot, will help to prevent soil-borne diseases and promote a healthy growing environment.
To maintain productivity, removing flowers at the bud stage is crucial, which can deplete the plant’s energy and reduce leaf production. Removing buds is critical since the leaves are the most sought-after part of the plant.
When harvesting individual basil stems, count two to three leaf nodes down the stem, then pinch the center stalk above a set of leaves. This technique encourages the plant to regrow quickly.
Harvesting basil is easy with a pair of snips; it’s an actual cut-and-come-again herb. Simply stand the stems at room temperature in a glass of water until you’re ready to use them. After mastering the quirks of this fascinating crop, there’s no reason to shy away from growing basil.
With thoughtful care, basil rewards you with robust, vigorous plants all summer. You might find yourself with more basil than you ever dreamed possible!

How to deal with Basil diseases
As with any plant, basils are not immune to diseases. Two of the most common diseases are fusarium wilt and downy mildew, each presenting its own set of challenges regarding prevention.
Fusarium wilt, caused by a soil-borne pathogen, is identifiable by yellowing leaves, discolored stems, and stunted growth, with sweet basil varieties particularly vulnerable.
Fortunately, breeding efforts have produced cultivars with relatively high resistance to fusarium wilt, and seeds certified as disease-free should be purchased. The disease overwinters in contaminated soil, crop rotation, and proper watering are crucial.
The current threat to basil is downy mildew, recognizable by yellowing on leaf tops and gray spores underneath. Although new sweet basil varieties resistant to downy mildew are being developed, few products are available to combat the disease.
It is essential to manage cultural techniques such as using resistant varieties like ‘Red Leaf,’ ‘Red Rubin,’ Thai basil, ‘Lemon,’ ‘Lime,’ and ‘Cinnamon,’ removing and disposing of infected plants, and sourcing seeds from reliable nurseries.
Importing plants and seeds from areas where the pathogen thrives, such as the South, should be avoided to break the disease cycle.
In Summary – Basil Varieties
In a nutshell, basil is a ubiquitous herb in the culinary world and is primarily known for being the key ingredient in pesto. It thrives in warmer temperatures and is often grown annually, with a tendency to wilt quickly in the face of frost.
Suppose you’re only planning to grow one herb in your garden. In that case, basil is an excellent option due to its minimal growing requirements, including warm temperatures, fertile soil, and full sun exposure.
With over 40 known varieties of basil, selecting the perfect one might be challenging, so it’s essential to determine how you intend to use it beforehand, whether as an ingredient in dishes or beverages, as a garnish, or to make pesto.
Basil plants range in size from 8 inches to 4 feet tall, and many different options are available, from sweet and Genovese to more unique varieties. Your local garden center might offer some options as seedlings, but to grow the most unusual types, starting from seed is necessary.
So, choose one or two of your favorite basil varieties, experiment with different tastes and textures, or opt for a Basil collection with some of the most popular types.
