Everyone should plant herbs in their home. Having home-grown herbs saves you the stress of going to the stores to get herbs and you get to enjoy freshly plucked herbs always.

One of the best types of herbs to grow is basil. Basil is easy to grow, but just like every other plant, it has some requirements. What are the requirements of basil? Does basil need full sun to thrive?

Basil grows best in full sun, but can also do well in partial sun. Basil grown in full sun grows faster and stronger, but full sun is not so necessary when growing basil in warm climates such as tropical and subtropical regions.

How many hours of sunlight does basil need? Can you grow basil using grow lights? We’ll cover these questions and more in this article.

Light Needs of Basils

Basil can grow in various light conditions. It is important that you note that your region (i.e. climate) plays a major role in the way you grow your basil.

Growing Basil in Temperate Regions

Most people in the United States will have to provide their basils with 6-8 hours of sunlight in spring and fall while providing slight shade during the summer.

If you live in a temperate region, you should plant your basil in the southern or western parts of your home as these places receive more sunlight.

Growing Basil in Subtropical Regions

If you are in Florida or other places considered subtropical, you need to pay close attention to your plants especially in the summer months.

You should provide partial shade to your basil in the afternoon while giving them sufficient sunlight. Plant your basil in the southern or eastern parts of your home.

Growing Basil in Tropical Regions

Tropical regions are warmer than other regions, so basil may grow poorly if exposed to the midday sun. You should grow your basil in partial shade so that they receive 4-6 hours of sunlight daily. You can grow your basil in the northern or eastern parts of your home.

If your basil is showing signs of light deficiency, do not grow them in the northern part of the home.

You can grow basil without sunlight. Using grow lights, you can enjoy fresh basil. You can also use a grow light to grow basil in your basement.

Make sure that you give your basils 10-12 hours of grow light daily so that they can grow as healthy as those grown under sunlight.

Other Needs of Basil

Asides from light, here are other needs of basils:

1. Soil

Soil is needed long as you are not growing hydroponics or aquaponics basil. You need well-drained and aerated soil to grow basil. You also need to make sure that there are no harmful microbes or nematodes in the soil.

2. Water

You should water your basils at least once daily. In the fall, you may choose not to water your basil. During the summer, make sure that your basil has enough water so it doesn’t look dehydrated.

3. The potential of Hydrogen (pH)

Basil needs a pH that is either neutral or slightly alkaline/acidic. The recommended pH for basil is 6.5 to 7, but they can grow at pH 6.0 to 7.5. Make sure that you pay close attention to the soil pH because it helps your basils to collect as many nutrients as they need from the soil.

4. Fertilizer

You enrich the soil with fertilizer. For basils, you can use organic or inorganic fertilizers. Since you may be growing basil as backyard herbs, organic fertilizer is best because it is cheaper and provides a wider range of nutrients.

Examples of organic fertilizers that you can give to your basils are compost and rotted manure.

5. Pruning Your Basils

You should occasionally prune your basils to encourage them to grow more branches and appear bushy. Aside from the growth of branches, pruning also encourages more leaf growth. You should continue pruning your basils in the growing season.

  2. Insert the Branch in a Glass of Water: 2-3 inches of the branch should be immersed in water.
  3. Change the Water Regularly: Make sure that the water remains crystal clear.
  4. *Observe the Branch for Roots: In 10-14 days, you should observe some roots growing in the immersed parts of the branch.
  5. Plant the Cutting: Follow the steps involved in transplanting basils above.

*You need patience to observe the root growth in this method.
