The world of gardening features a great variety of herbs that prefer what we call “full sun”. In this article, we will list some of the most popular full-sun herbs.
Considerable controversy surrounds the topic of full sun, partial sun, partial shade, and shade plants, mainly because these terms aren’t “scientifically” accurate.
Nonetheless, they are very important in gardening because they highly increase the success of growing healthy plants. They’re also very “practical,” and that suits this activity very well.
What Does “Full-Sun” Mean?
Most gardeners agree that full sun means at least 6 hours of exposure to sunlight, and some people say that 8 hours would be ideal for full-sun plants.
In reality, your plants don’t depend that much on the duration of light exposure but rather on the quality of light they’re getting.
The secret lies in what we call PPF and PPFD. PPF indicates the amount of photosynthetically active photons (light that stimulates photosynthesis) that a source produces, while PPFD indicates how much of that amount is reaching your herbs.
Some gardeners, however, wanted to make it easier for you and decided to use the notions of partial or full sun/shade, and their effect turned out to be very positive on gardening. So, don’t worry. You don’t really need to calculate the PPF, PPFD, or anything else. You can just stick to these terms.
What’s really important, though, is that in some places, such as the southern U.S., the sun can send plant-damaging heat during some hours of the day. In that case, if the herbs you’re growing aren’t heat tolerant, you could be facing a major problem.
That’s why knowing if your herb is full sun isn’t always enough. You should also consider the climate your herb prefers.
In some instances, there is a simple solution that would help you overcome such a problem: morning sun, which is said to be brighter and less heat intense. In other words, your full-sun herbs would be getting the best quality of light during the morning.
Afternoon sun, on the other hand, can send very warm light that can hurt some plants that aren’t used to hot conditions.
So, remember it’s always better to give your full-sun herbs more morning sun than afternoon sun.
