When it comes to growing herbs like basil indoors, one of the most critical factors to consider is the direction of the window and the amount of sunlight it receives. Many gardening enthusiasts wonder if a north facing window can provide sufficient light for basil to thrive. In this article, we will delve into the world of indoor herb gardening, focusing on the specific needs of basil and the potential of growing it in a north facing window.
Understanding Basil’s Lighting Requirements
Basil is a sun-loving herb that typically requires a significant amount of direct sunlight to grow well. Ideally, basil needs at least 4-6 hours of direct sunlight per day to produce healthy leaves and prevent legginess. However, the amount of sunlight a north facing window receives can vary greatly depending on the location, time of year, and surrounding environment.
Factors Affecting Light Intensity in a North Facing Window
Several factors can influence the light intensity in a north facing window, including:
The time of year: During the winter months, the sun is lower in the sky, resulting in less direct sunlight entering the window.
The location: If you live in the Northern Hemisphere, a north facing window will receive less sunlight than one facing south. The opposite is true for the Southern Hemisphere.
Obstructions: Trees, buildings, or other obstacles outside the window can block or filter the sunlight, reducing the intensity.
Window size and type: Larger windows or those with a south-facing component can increase the amount of sunlight available.
Measuring Light Intensity
To determine if your north facing window receives sufficient light for basil, you can use a light meter or observe the shadows. A general rule of thumb is to place your hand in the window and observe the shadow. If the shadow is barely visible or has a soft edge, the light is likely sufficient for basil. On the other hand, if the shadow is dark and distinct, the light may be too weak.
Growing Basil in a North Facing Window: Challenges and Solutions
While a north facing window may not provide the ideal amount of sunlight for basil, it is not impossible to grow this herb in such conditions. With some creative solutions and careful planning, you can still enjoy a thriving basil plant in a north facing window.

Can Basil Grow in a North Facing Window?
Basil can grow in a north facing window, but it may not thrive as well as it would in a south facing window. North facing windows typically receive less direct sunlight, which is essential for basil’s growth. Basil requires at least 4-6 hours of direct sunlight per day to produce healthy leaves and prevent legginess. If your north facing window receives indirect sunlight for most of the day, you may still be able to grow basil, but you may need to supplement with grow lights to ensure it gets enough light.
To increase the chances of growing basil in a north facing window, choose a variety that is known to tolerate shade or low light conditions. Some popular varieties include ‘Genovese’, ‘Sweet Basil’, and ‘Thai Basil’. You can also try using a mirror or reflective surface to reflect any available sunlight onto the plant. Additionally, make sure the soil is well-draining and the temperature is between 60-70°F (15-21°C), which is ideal for basil growth. With proper care and attention, you can still enjoy a healthy and flavorful basil plant in a north facing window.
How Much Light Does Basil Need to Grow?
Basil requires a significant amount of light to grow, especially when it comes to producing healthy leaves and preventing legginess. As mentioned earlier, basil needs at least 4-6 hours of direct sunlight per day. However, if you’re growing basil in a container, you can move it to a sunny location outdoors during the day to give it a boost of sunlight. If this isn’t possible, you can also use grow lights to supplement the natural light. The type and intensity of the grow lights will depend on the specific variety of basil you’re growing and the amount of natural light it receives.
The intensity of the light also plays a role in basil’s growth. The light should be bright, but not scorching. If the light is too intense, it can cause the leaves to become scorched or discolored. A good rule of thumb is to provide light that is similar to the light you would find in a sunny windowsill. If you’re using grow lights, make sure to follow the manufacturer’s instructions for the recommended distance and duration of use. By providing the right amount and intensity of light, you can promote healthy growth and prevent problems like legginess, leaf drop, or weak stems.
What are the Best Varieties of Basil for Low Light Conditions?
There are several varieties of basil that are known to tolerate low light conditions, making them perfect for growing in a north facing window. Some popular varieties include ‘Genovese’, ‘Sweet Basil’, and ‘Thai Basil’. These varieties are known for their compact growth habit and ability to produce healthy leaves in low light conditions. Another variety that does well in low light is ‘Purple Basil’, which has beautiful, deep purple leaves and a slightly sweeter flavor than other varieties.
When growing basil in low light conditions, it’s essential to choose a variety that is known to tolerate shade. Look for varieties that are specifically labeled as “low light” or “shade tolerant”. You can also experiment with different varieties to see which one does best in your specific growing conditions. Keep in mind that even shade-tolerant varieties will still require some direct sunlight to produce healthy leaves.
