Despite not being particularly common in Kenyan cuisine, approximately 10% of the basil produced is consumed locally, while the majority is exported to countries such as the Netherlands, Denmark, Germany, and France, among others.

Basil possesses a diverse range of therapeutic properties, including its ability to address various ailments, anti-inflammatory effects, promotion of circulation and immune response, as well as being rich in antioxidants.

Varieties

Here are some popular varieties of Basil:

    1. Lemon basil: This variety imparts a refreshing lemon flavor to dishes.
    2. Cinnamon basil: It adds a subtle hint of cinnamon to enhance the taste of a dish.
    3. Purple basil: This type of basil contributes a visually pleasing purple color to recipes.
    4. Thai basil: Known for its sweet licorice flavor, it adds a unique taste to dishes.
    5. Camphor basil: This basil variety carries a distinct camphor-like aroma.
    6. African blue basil: A unique basil type with a vibrant blue color and a rich flavor.

Ecological Requirements

Basil is a low-maintenance herb that is often cultivated in outdoor settings but can also thrive indoors, particularly in greenhouses. Adequate sunlight is crucial for its growth, necessitating a minimum of 6-8 hours of sunlight per day.

Similar to other herbs, Basil flourishes in well-drained soil that is nutrient-rich. The optimal pH range for growing basil lies between 6 and 7.5.

Basil is fond of warm temperatures and is sensitive to frost, making it essential to protect the crop from freezing conditions.

Planting

Raising seedlings

The most effective way to accomplish this is by growing basil indoors, for example, within the confines of a greenhouse.

Procedure

Here are the rephrased instructions for growing basil:

    1. Build raised seedbeds.
    2. Apply a soil drench using a combination of LOYALTY 700WDG (10g), PYRAMID 700WP (100g), and OPTIMIZER (20ml) mixed with 20 liters of water. This mixture helps eliminate soil pests and diseases, break seed dormancy, and encourage even germination.
    3. Sow the basil seeds thinly and lightly cover them with soil.
    4. Mulch the seedbed and ensure it is adequately watered.

Basil seeds typically germinate within a span of 5-7 days.

Transplanting

Here are the rephrased instructions:

    1. When the seedlings reach a minimum height of 3 inches and have developed two sets of true leaves, they are ready for transplanting.
    2. It is highly recommended to harden off the seedlings before transplanting, especially if they are intended for outdoor cultivation. This process helps reduce transplanting shock.
    3. Prepare the soil to a depth of 6-8 inches. Incorporate DAP (diammonium phosphate) and composted manure into the soil. To enhance nutrient absorption by the plants, mix the fertilizer and/or manure with HUMIPOWER (1kg of Humipower for every 50kg of fertilizer or 1 ton of manure).
    4. Plant the seedlings approximately 10-15cm apart. For smaller plants, maintain a spacing of around 15-20cm.

Note:

    1. To prevent transplanting shock, it is recommended to spray OPTIMIZER (10ml per 20 liters) onto the transplants.
    2. Basil seedlings are delicate and should be handled with care.
    3. Mulching serves the dual purpose of retaining soil moisture and weed control. Options for mulching include grass clippings, chopped leaves, plastic mulch, or barley straw.
    4. Thinning the plants to a spacing of approximately 6-12 inches is advised for optimal results.
    5. It is important to avoid overcrowding the plants. Proper air circulation around the plants is crucial for their overall health.

Irrigation

    1. If basil is grown outdoors, watering should be performed more frequently. It is recommended to water at the base of the plants, avoiding wetting the leaves and stems to prevent downy mildew issues.
    2. Drip irrigation is preferable over overhead watering with sprinklers for basil cultivation.
    3. It is important to avoid over-watering as excessive moisture can result in a loss of flavor in the basil leaves.

Pruning

    1. Once the seedlings have developed their first six leaves, it is recommended to pinch them above the second set of leaves.
    2. Prune the branches back to their first set of leaves whenever a branch has grown 6-8 leaves.

Weeding

    1. Weeds pose a threat to the crop as they compete with it for nutrients, moisture, space, sunlight, and can also harbor pests. Therefore, weed control is essential.
    2. Manual weeding is recommended in basil gardens and should be performed with care. Weeds located near the plants should be cut off at ground level.
    3. Prior to planting, spraying weeds with CLAMPDOWN 480SL (200ml per 20 liters) significantly reduces weed growth throughout the entire crop season.

NOTE;

    1. When the crop begins to flower and produce seeds, it is advised to pinch off the tops of the plants rather than the flowers. Pinching the tops promotes bushier growth in the plants.
    2. Removing the flowers as they start to form does not stimulate new foliage; instead, it encourages the formation of flowers in the leaf axils, which can reduce the overall yield of the plant.
    3. If heirloom basil seeds were initially planted, the harvested seeds can be saved and used for the next season’s crop.
    4. It is important to note that seeds from hybrid varieties cannot be saved and used for planting in the subsequent growing season.

Pests & Disease Management

Pests

Cutworms: These are caterpillars that are brown to black in color and reside in the soil. They have a habit of cutting and consuming the stems of young seedlings and transplants. Severe infestations can result in a complete loss of the crop if not managed.

To address cutworms:

  • Treat the seeds with SHIELD 600FS at a rate of 3ml per kilogram of seeds.
  • Drench the soil with either PROFILE 440EC (60ml per 20 liters) or PENTAGON 50EC (20ml per 20 liters) to control the pests.

Beetles: These insects primarily feed on the tender leaves, leaving behind the larger veins.

To control beetles:

  • Spray either SINOPHATE 750SP (20g per 20 liters), LEXUS 247SC (8ml per 20 liters), or KINGCODE ELITE 50EC (10ml per 20 liters) onto the affected plants.

Slugs: These pests feed on the leaves, causing ragged holes to form.

To combat slugs:

  • Drench the soil with either PROFILE 440EC (60ml per 20 liters) or RANGER 480SL (60ml per 20 liters) to manage the slugs.

Aphids: These pests feed on the crop by extracting sap from the plants. Infested leaves may curl and crinkle. Additionally, aphids secrete honeydew, which promotes the growth of sooty mold.

To address aphids:

  • Spray either KINGCODE ELITE 50EC (10ml per 20 liters), LEXUS 247SC (8ml per 20 liters), or PENTAGON 50EC (10ml per 20 liters) onto the affected plants.
  • To clean the sooty mold, spray JAMBO CLEAN at a rate of 100ml per 20 liters.

Maturity, Harvesting & Post-Harvest Handling

The maturity period for basil ranges from 60 to 70 days from the time of planting, varying depending on the specific variety.

Harvesting of basil involves picking or plucking the topmost leaves once the plants have approximately 8 leaves. This can be done once or twice a week.

For the best-flavored basil, it is recommended to harvest before the crop starts flowering. This practice also stimulates branching and increases yield. However, if flowering has already begun, the flowers are still edible and can be a tasty addition to salads.

It is advisable to harvest a few leaves from each plant rather than picking all the leaves from a single plant.

At the end of the growing season, all the leaves are harvested, and the stems are cut off.

Basil can be used either fresh or in its dried form.

Freezing is the recommended method for storing basil as it helps retain its flavor without any loss.

Alternatively, basil can be dried, although its flavor diminishes over time. To dry basil, place the stems in a well-ventilated and shady area for 3-4 days. If the leaves are not completely dry, they can be placed in an oven on the lowest heat setting with the door slightly open. It is important to turn the leaves regularly for even drying. Once the leaves are fully dried, store them in dry, airtight containers for up to 12 months.

Food dryers can also be used to dry basil. Simply lay the stems on the trays and seal the dried leaves in an airtight container. Store them in a cool, dark area or a root cellar, where they can retain their quality for up to a year.

Refrigeration can be used to store basil for a week or more, but the flavor diminishes over time. Basil is most flavorful when used fresh.
