How Much Sunlight Do Succulents Need?

It is not a secret that succulents love sun and they need sunlight to maintain their unique shapes and colors. While some succulents grow very well in the full sun, some varieties prefer bright sunlight or partial shade to thrive. In this blog, we would show you how succulents react when they get too much sunlight or under-exposure.

Under-exposure

Succulents that do not receive enough sunlight will exhibit problems such as elongation or etiolation, which means the stems and leaves will stretch and get leggy. Because the plants stretch to seek more light to do photosynthesis.

Another problem will occur is succulents  like Echeveria, Crassulas, will lose their vibrant pigmentation and will become pale or revert to a dull green color. Succulents need adequate sunlight to become “stressed” and display their true beauty by showcasing their full range of vibrant colors.

Over-exposure

Succulents by nature do better with a lot of sun exposure, but they do need protection from direct sunlight or intense heat in hot summer.


As overexposure will cause sunburn on the leaves just like people will get sunburn if we don't get any protection on our skin.

You can gradually introduce the succulents to the direct sunlight. Most succulents will get used to it when they get stable. That is why we already say it is not suggested to place your new arrival succulents in direct sunlight.

So how much sunlight they need?

Therefore, we do not recommend exposing your succulents to direct full sun in temperatures above 90°F. Place them under filtered sunlight or give them partial shade to make sure they get at least 4-6 hours of sun a day. They will be happy to thrive.

Is there any ways to fix low-light conditions?

The answer is yes! 

1. The easiest way is growing succulent near the window. A south-facing window or east-facing window is a good choice because morning sun is brighter and last for long time.

2. Different with the 1st way, there are some window box planters which are very beautiful. This is half indoor and half outdoor way to plant succulents. To avoid the window box hold too much water especially after rain, be sure to pick planter pot with drainage holes to let the exceed water drop out.

3. Artificial grow light is another good way to fix low-light conditions especially in winter season and in some rainy cities. There are lots of grow light in the market. You can read lots of reviews and compare different brands before placing the order.
