What does the full sun and part shade mean for plants? What’s the difference between Part Sun and Part Shade? Burning questions that we gardeners need to know!
Out of all the requirements and things a plant needs to grow, light’s got to be near the top of that list. But not all of our plants are the same. Just like us, each one has a preferred amount of sunshine that they’d like, while tolerating a range right around that level.
Light levels for plants are a crucial parameter in the success of the crop. Without access to adequate light, plants will suffer and so will your harvests. On the flip side, too much sun or too intense more likely can be just as bad for other crops. This article is all about the Sun. More specifically in this article, we’re going to explain what the terms full sun, partial sun, partial shade, and full shade mean. So let’s get into it.
On the back side of every seed packet, the good ones anyways, there’s a whole host of information provided and one of the key things they sometimes tell you is the plant’s light requirements.
These light requirements are always given as a minimum and they come in four different designations.
Light requirements for plants
1. Full sun for plants
First up is full sun, meaning the plant needs at least six to eight hours of direct unobstructed sun per day. It will probably not blossom if you grow it in less light, and the plant may even die in some situations.
2. Part sun for plants
Next, we have part sun, which designates plants that require only four to six hours of that same direct sun. This is typical for windows facing east that get a few hours of morning light and then a few hours of the indirect afternoon sun.
3. Part shade for plants
Then we have part shade, which designates plants that still needs 4+ hours of sun, but may not be tolerant of hot midday hours. It is often synonymous with the part sun. However, some designate this category for plants that require part shade and are not really tolerant of that direct midday sun.
4. Full shade for plants
And lastly, we have full shade and this is for plants that can’t tolerate or in fact require less than four hours of direct sunlight per day.
Again noting that some of these plants actually don’t like any of that midday Sun at all. Because remember not all sun is created equal. Direct sun in the early morning and direct sun at noon are two entirely different beasts. Not to mention geography can play a huge part as well.
The sun intensity where I live can be completely different from what plants experience in places like Texas and Florida. Always remember the right plant for the right place.

FAQs on what does the full sun and part shade mean for plants
Why do some plants need full sun?
Sunlight energy is essential for plants to manufacture the nutrients they require. However, there are instances when they take in more energy than they can utilize, and this extra can harm important proteins. They turn the extra energy into heat and release it back into the environment as a form of self-defense.
What plants do better in full sun?
How do you measure sunlight in plants?
The procedure involves holding the light meter as close to the plant’s leaves as you can, with the sensor pointing away from the plant and toward the source of incoming light.
Do succulents like the full sun?
Succulents love the direct sun, but if yours is consistently in the same spot, it’s possible that only one side is getting enough light. It is important to rotate your plants frequently. Due to their natural tendency to tilt toward the sun, succulents will stand up straighter when rotated.
What is considered bright light for plants?
A window that receives direct light all day long and faces either the south or west is considered to have bright light.
What time is the morning sun for plants?
The sun is at its brightest between 10 a.m. and 4 p.m. The sun is the least intense in the morning. The hot afternoon light can burn the leaves of some plants, even those of some sun-loving types, so a few hours of early sun isn’t as intense as a few hours of mid-day and afternoon heat.
Is morning sun considered full sun?
Full sun is defined as any period of sunlight lasting at least six hours.
What happens if shade plants get too much sun?
The leaves of shade plants that are grown in the sun may become burnt and grow poorly. This can cause the plant to die if it is not fixed. The plant may need to be moved or given extra shade if you notice these symptoms.
Do plants still get sun on a cloudy day?
Without sunshine, plants cannot use the photosynthesis process to turn nutrients and carbon dioxide into energy. They create far less of the energy required for growth and blooming on cloudy days.
