Any avid plant lover knows that light is essential to the production of photosynthesis, which is vital to plant growth. Of course, the amount of light that is required by plants will vary greatly based on the species. But, no indoor plant will be able to get the light it needs if the windows aren’t clean enough to let it shine through.
Why Your Plants Want Clean Windows
When dust and dirt accumulate on windows, it prevents natural light from passing through. In fact, 50% of natural sunlight can be blocked by dirty windows, even though the dirt may not be visible to the naked eye.
Regardless of the number of windows in your home or what direction they face, the light that flows in provides countless benefits to your plants, your home, and you. Also, windows offer protection against direct exposure to the sun’s UV rays, which can result in the premature aging of houseplants.
Basically, windows reduce the intensity of sunlight by as much as 50% in comparison to direct sunlight outside. This is because as light passes through the glass panes, the light is refracted.
Interestingly, just as the seasons change, so does the intensity of sunlight that flows in through windows. And while plants aren’t particularly picky when it comes to light sources, natural sunlight benefits plants, as well as humans.
Think for a moment how invigorating it feels to have the warmth of the sun’s rays on your skin. The sunlight boosts your body’s production of vitamin D, which also supports a healthy mood, immune system, and brain function. Have you ever noticed how plants grow in the direction of the light they’re receiving? For this reason, it’s a good idea to rotate the plant pots on a regular basis to promote even growth.
Dirty Windows Mean Dirty Air
In addition to letting the light in, clean windows help reduce the risk of mold growth, which can cause a variety of respiratory issues for you and your family. Likewise, overly damp soil due to poor air circulation can prove detrimental to plant health.
Additionally, by cleaning your windows regularly throughout the year, the sunlight can actually help heat your home during the winter months, thus reducing utility costs. And, just as we prefer cozy temperatures throughout the year, most houseplants require daytime temperatures between 65 and 75 with nighttime temps staying above 55 in order to stay healthy.
So, why not take advantage of the sun’s natural warmth during the summer months? Simply invest in sheer curtains to block the intensity of the sun’s rays while opening the windows to circulate fresh air.
Brighten Up Your Home
The next time you notice streaks or dirt on your windows, take a few moments to clean them. Not only will you be helping ensure your plants get ample sunlight in order to convert water and carbon dioxide into plant food, but you’ll be improving the ambiance of your home for your personal enjoyment while also preserving the lifespan of your windows and frames.
