Is Too Much Light on Plants a Bad Thing? [ANSWERED]
Believe it or not, there is such a thing as too much light on plants.
Like us, plants need periods of darkness in their day to rest and remain strong. Plants that have been exposed to too much light will show symptoms, like:
- initial loss of color or pale leaves,
- yellowing leaves at the top of the plant, with
- browning at the tips (like sunburn),

Today, at the Garden Bench Top, we are going to tackle all those questions about too much light on plants. We’ll look at what happens to a plant that is on the receiving end of too much light. We’ll also gain a better understanding of different types of lighting, and how you can adjust your lighting for your own plants.
So, if you’re ready grab a pair of sunglasses, because it’s about to get bright in here!
What Happens if a Plant has Too Much Light?
Plants that are over-exposed to light will exhibit some tell-tale symptoms – or cries for help – to tell you that some immediate action is required.

Failure to recognize these signs of too much light, will often result in a quick decline in your plants’ health, eventually leading to death.
As we mentioned earlier, a plant requires darkness to rest and recuperate from the days’ growth. It would be like keeping you in a room with constant light for 7 days straight. The constant light will lead to sleep deprivation, which will eventually lead to a significant reduction in your mental and physical capabilities.
In addition, depending on the light source, the constant heat from the light can dry your plant out to the point of complete dehydration. And we don’t think we need to tell you what happens after that.
