Basil plants are one of the most popular herbs to grow and also one of the easiest. Dwarf basil boasts all the same benefits as regular fresh basil, but is more compact and darn good looking. This herb’s peppery flavour makes it amazing for savoury dishes, and it’s a rich source of vitamin C and antioxidants. The extremely aromatic leaves also have a delightful variety of flavors, from the slightly lemony mint of sweet basil to cinnamon and licorice. Leaf colors span from rich green to deep purple, with smooth or crinkled leaves. The flowers are insignificant but very popular with bees.
All types of basil grow easily in warm, sunny weather. The leaves are commonly used in cooking, but the flower buds are also edible. This fast-growing herb thrives equally well in gardens and containers. With sufficiently warm weather, new basil plants are ready for pruning (to encourage bushier growth) in about six weeks.

When to Plant?
This will be determined by your planting zone. There is a final frost date for each area. As a result, you can plan your gardening activities around this date. Check our Frost Dates Across North America: First & Last Frost Dates Chart. However, the date will not be the same for every plant. Basil should be planted after the last spring frost. You can plant during the summer as well.
How to Plant
To plant basil seeds, you need a 0.25 to 0.5 gallons pot or large container at least 6″ deep so that the basil shoots can grow at least 4″ apart. A container for growing basil must necessarily have drainage holes.
If your container does not have drain holes, add stones to the container’s bottom to act as a drain. Plant basil in well-drained, fertile soil with direct sunlight for at least 6 – 8 hours a day.
The soil temperature for planting basil should be 50°F – 70°F. The first sprouts of the basil will appear in 7 – 12 days.
When growing basil, it is best to use larger pots. The smaller the pot, the more often the plant needs to be watered. On hot summer days, the soil can dry out, which will harm the plant. A sunny windowsill is an ideal spot to grow basil. The best time to plant basil is late in the day or early morning so that the plant is not immediately exposed to the scorching sun. Companion planting: Plant basil among other herbs and vegetables with similar lighting and watering needs, e.g., parsley or tomatoes. Some people say tomatoes taste better when they neighbor basil. Plant basil alongside chamomile, lettuce, oregano, and peppers.
How to Cultivate
Sun – Needs at least six hours of sun per day.
Spacing – If planting more than one, space the basil plants about 4 inches apart to allow for growth.
Water – Large beds or planter boxes may only need water every 3 – 4 days.
Soil – Basil loves moist, rich, well-drained soil with a pH of 6.0 – 7.0.
How to Harvest
When propagated by seeds, the crop is harvested in about 2 – 2.5 months from the appearance of the first shoots.
Once the basil plant is 6 – 8 inches tall, you can harvest it.
Basil has no specific harvest time – just choose any time you want, and do it the way you want it.
Another nice thing is that the more often you harvest, the more basil you get.
Harvest before the seeds form. When basil goes to seed, the leaves will often have a bitter flavor.
Hydroponics
Germination: Begin by germinating the seeds in a damp paper towel or seed starter kit and keeping them in a warm, dark place until they sprout.
pH range: Maintain a pH range between 6.0 and 6.5 by using a pH meter and adjusting with pH up or pH down solutions. This range ensures that the plant can absorb nutrients effectively.
EC: Check the electrical conductivity with an EC meter and aim for an ideal range of 1.2 to 1.8 mS/cm. This level provides enough nutrients for the plant to grow healthily.
PPM: The recommended total dissolved solids (TDS) or parts per million (PPM) range for Dwarf basil is between 800 and 1600 ppm.
Humidity: Maintain a relative humidity level of 50-70% for optimal growth of Dwarf basil.
Light hours: Dwarf basil requires at least 12-16 hours of light per day for optimal growth. You can use artificial grow lights or place the plants near a sunny window.
Temperature air: The optimal air temperature for Dwarf basil growth is between 70-80°F during the day and 60-70°F at night.
Temperature water: Should be between 65-75°F. You can use a water heater or cooler to maintain the desired temperature.
With these guidelines, you should be able to grow healthy Dwarf basil plants hydroponically. Good luck, and happy growing!
Common Pests and Diseases
Cercospora leaf spot (Cercospora ocimicola)
Symptoms: Circular to irregular dark spots on leaves with light centers
Cause: Fungus
Management
Avoid overhead irrigation and splashing plants with water, instead water plants from the base and apply a layer of mulch around the plants to reduce water splash; remove and destroy any symptomatic leaves; minor infections can be controlled by spraying weekly with a fungicide containing potassium bicarbonate
Downy mildew (Peronospora belbahrii)
Symptoms: Yellowing leaves; discoloration often begins around the middle vein and spreads outwards; gray fuzzy or downy growth on the lower surface of the leaves; brown to black angular necrotic patches on the plant.
Cause: Fungus
Management
Grow tolerant varieties; apply protective fungicide; ensure good air circulation around greenhouse grown plants; use drip irrigation to avoid wetting foliage.
