If you live in apartments then windows and balconies are probably the places best suitable for growing plants. Though it sounds very limiting there are various options for growing plants. You can use windowsill and shelves, on plant stands, planters and beautiful window boxes to give your house a refreshing look.

The success in indoor gardening depends on various factors like watering, type of soil and containers, humidity etc. But in this post, we will talk about light and sunlight in particular.

Light is a very important factor in any form of gardening. But when you talk about indoor gardening, light is absolutely crucial.

Light Intensity Inside Your House

The light intensity in your house is not equal in every part. Some have intense direct sunlight whereas some of the places may never receive a tiny bit of light. The intensity also varies according to the seasons or time of the day. Here is how the light intensity varies relative to window orientation:

South-facing Windows:

In the northern hemisphere, the sun follows a slightly southern east-to-west arc across the sky. Because of this fact, a south-facing window usually gets the most intense light during the day. You can get direct sunlight within 2 to 3 feet of the window. The indirect light lights up to 5 ft and partial shade 8 feet from the window.

North-facing Windows:

They tend to have the weakest light intensity. They also have the deepest shade throughout the window compared to other windows. North-facing windows can only give partial shade up to 5 feet away. The best use of these windows would be to grow shade-loving plants during the summer months. Unless you arrange artificial grow lights, in winters, you won’t be able to grow anything.

East-facing Windows:

The unique nature of east-facing windows is it only gets sunlight from the morning sun when the rays are not very strong.

West-facing Windows:

West windows get the full afternoon and evening sun. The intensity of the sunlight is stronger compared to the east-facing windows but lesser than the south-facing windows.

East and west-facing windows get some direct sunlight up to 3 feet and indirect light up to 5 feet away, during morning and afternoon.

Plant Selection:

The general rule is to place only those plants that need plenty of sunshine on the south side. If your plant is a shade-loving plant, place it on a north-facing window. Windows that are on the east and west sides are best for growing plants that need medium light.

Now, Although natural light is good for your plants it is not mandatory, you can also use artificial lighting (the set-up might involve a little bit of work) to grow plants. The best combination would be to use the natural sunlight (with the use of proper shedding) during the summers and then supplement with artificial lights in the winter.

Just like the plant selection, your site selection also needs to be more specific. When you pick a spot for growing plants the key here is that it should not only allow ample sunlight but also can be shaded in some way.

Growing Plants On A South-Facing Window

Most gardeners prefer, south-facing windows, as they allow abundant light. But depending on where you’re located in the country, this could be a boon or a bane.

When you have a south-facing window it no doubt allows sunlight but the heat also streams in.

The environment can be a very hostile place for many houseplants. Only a few sun-loving plants love south-facing windows during summers. If you put some plants in the direct sunlight during the hottest part of a summer day, especially without proper airflow, You might just burn them to death.

But the same window becomes the most desirable place winter-flowring plants during cold winters.

How to Protect Plants on South-facing Windows During Hot Summers

It is crucial that you take utmost care of your plants especially during the summer months. The leaves and the roots of the plant can become overheated due to too much sun exposure. Even if they don’t die, they use up a lot of energy to protect themselves against extremes in light and temperature, that they cannot thrive.

Here are some useful ways to protect your plants during hot summer:

  • You can protect the roots from extreme heat by placing a growing container inside another container. This type of double potting method insulates the roots from extreme heat and it also looks nice aesthetically.
  • Use blinds to cover windows. Blinds are easy to open and close and so you can adjust the heat and light very efficiently.
  • Use a sheer curtain or fabric screen. This allows some bright light in and stops a lot of heat from outside. Cover the windows during the hottest part of the day and remove them once the heat reduces.
  • You can also use barriers to shade the bottom portion and allow direct light only at the top of the window. This will keep your roots cool but will give leaves the light so that the photosynthesis process does not stop.
  • Rather than placing plants horizontally use shelves like these and place them vertically. This way the plants will get more indirect sunlight.
  • Tall outside structures like an awning can help you protect plants from midday sun outside.
  • Also, arrange good ventilation during the hottest parts of the day Without proper ventilation the plants won’t survive.
