How To Grow Basil In A Greenhouse - 6 Easy Steps

Culturing basil (Ocimum basilicum) in a greenhouse environment has gained significant attention due to its numerous advantages and the increasing demand for this aromatic herb.

Greenhouses provide an optimal environment for basil growth, allowing for extended growing seasons, enhanced control over environmental factors, and protection against adverse weather conditions. To successfully grow basil in a greenhouse, several key aspects must be considered. Here are six easy steps on how to grow basil in a greenhouse:

1.Choose A Suitable Greenhouse

Choose A Suitable Greenhouse

In selecting a suitable greenhouse for optimal basil growth, several factors should be taken into consideration. First and foremost, the greenhouse should provide an ample amount of sunlight. Basil plants thrive in direct sunlight, requiring at least six to eight hours of exposure daily.

Therefore, it is essential to choose a greenhouse positioned in an area that receives sufficient sunlight throughout the day. This can be achieved by selecting a greenhouse with a transparent roof or walls that allow sunlight to penetrate easily.

In addition to sunlight, proper ventilation is crucial for the healthy growth of basil plants. A well-ventilated greenhouse helps regulate the temperature and humidity levels, preventing the plants from becoming too hot or damp.

2.Prepare The Soil

Prepare The Soil

To prepare the soil for optimal basil growth, it is crucial to use a well-draining soil mix that is rich in organic matter. The proper soil composition provides the necessary nutrients and moisture retention capabilities for the basil plants to thrive. When choosing a soil mix, it is important to consider the specific preferences of basil.

This herb tends to prefer slightly acidic soil conditions, with a pH level ranging between 6 and 7. Therefore, it is advisable to test the pH level of the soil and adjust it if necessary by adding organic amendments such as compost or peat moss.

Ensuring proper soil drainage is imperative for the healthy development of basil plants. By using a well-draining soil mix, excess water can flow freely through the soil, preventing the roots from being waterlogged.

3.Start With Quality Seeds Or Seedlings

Start With Quality Seeds Or Seedlings

To ensure a successful basil harvest, it is imperative to start with the highest quality seeds or seedlings. Investing in reputable sources that specialize in quality basil seeds or healthy seedlings can greatly impact the overall growth and productivity of your basil plants.

High-quality seeds have a greater chance of germination and producing strong, vigorous plants. Similarly, healthy seedlings are likelier to thrive and adapt well to different growing conditions.

When purchasing basil seeds, it is essential to select seeds that are fresh and viable. Look for seeds that are plump, well-formed, and have a uniform colour. Avoid seeds that appear shriveled, discolored, or damaged, as they may have a lower germination rate. Additionally, consider choosing organic or heirloom basil seeds, as they tend to have a higher genetic diversity and may offer unique flavour profiles.


Planting is a crucial step in the growth and development of plants. Whether you are using seeds or seedlings, proper planting techniques are essential to ensure successful establishment and healthy growth. When using seeds, it is important to sow them directly into pots or trays filled with the prepared soil.

This allows the seeds to contact the soil, promoting germination and root development directly. It is recommended to follow the instructions on the seed packet regarding planting depth and spacing between seeds. This will ensure that each seed has enough space to grow without competition for nutrients and sunlight. Additionally, it is important to water the seeds regularly to keep the soil moist and provide optimal conditions for germination.



Basil, a popular culinary herb known for its fragrant leaves and versatile uses in the kitchen, thrives under consistent moisture conditions. Adequate watering is crucial for the optimal growth and development of basil plants. To ensure the plants receive the necessary hydration, it is recommended to water them regularly.

This can be achieved by providing a sufficient amount of water to the soil, taking care not to drench the plant. Overwatering, in particular, must be avoided as it can have detrimental effects on the basil’s root system, leading to the development of root rot.

It is important to balance watering the basil plants adequately and avoiding excessive moisture. To prevent overwatering, it is advisable to allow the soil to dry out slightly between waterings. This practice enables the roots to access oxygen and promotes healthy growth.

6.Provide Adequate Light And Temperature

To successfully cultivate basil in a greenhouse, it is crucial to provide adequate light and maintain optimal temperature conditions. Basil plants are known for their preference for full sunlight. This means that the greenhouse should be positioned in an area that receives maximum exposure to sunlight throughout the day.

A south-facing location is often ideal, allowing the plants to receive the most direct sunlight. It is also important to regularly monitor the sun’s movement and adjust the position of the greenhouse accordingly to ensure the plants receive consistent and uniform light throughout the growing season.

In addition to light, maintaining the right temperature is essential for the healthy growth of basil plants. Basil thrives in warm conditions, with an optimal temperature range of 70-85 degrees Fahrenheit (21-29 degrees Celsius).

Harvesting And Post-Harvest Handling Of Basil

Harvesting And Post-Harvest Handling Of Basil

The harvesting and post-harvest handling of basil is a crucial process that significantly impacts the quality and shelf life of this aromatic herb. Basil, scientifically known as Ocimum basilicum, is commonly cultivated for culinary and medicinal uses. The success of the harvesting process depends on several factors, including the stage of growth, time of day, and weather conditions.

Harvesting Basil:

  • Select mature basil plants with healthy leaves.
  • Use clean and sharp pruning shears or scissors to cut the basil stems just above a pair of leaves.
  • Avoid damaging neighboring leaves or stems during the harvesting process.
  • Harvest in the morning when the essential oil content is the highest.
  • Regularly harvest the basil to promote new growth and prevent flowering.

Post-Harvest Handling Of Basil:

  • Remove any damaged or discolored leaves and discard them.
  • Rinse the basil leaves gently with cold water to remove dirt or debris.
  • Pat the leaves dry with a clean towel or use a salad spinner to remove excess water.
  • Bundle the basil stems and secure them with a rubber band or twine.
  • Place the basil bundles in a jar or glass filled with water, ensuring the stems are hollow.
