Coleus plants can handle morning sun. In fact, many modern coleus varieties have been bred to tolerate more sunlight than their predecessors. However, it is important to note that while they can handle some direct sunlight, they still prefer dappled shade and should not be exposed to intense midday rays.
When coleus plants are exposed to too much sun, their foliage can become scorched and faded. The leaves may develop brown patches or even turn completely brown. This can be quite disappointing, as the vibrant colors and patterns of coleus leaves are one of their main attractions. Therefore, it is important to provide them with some shade during the hottest part of the day to prevent this damage.
On the other hand, if coleus plants receive too little light, they may exhibit weak growth. The leaves can become leggy and pale, and the overall plant may appear stretched and spindly. In order to promote healthy growth and vibrant foliage, it is important to provide them with enough light.
Personally, I have found that placing coleus plants in a location where they receive morning sun and afternoon shade works best. This allows them to benefit from the gentle morning rays, which can enhance the colors of their leaves, while still protecting them from the intense heat of the midday sun.
If you are unsure about the amount of sunlight your coleus plants are receiving, you can observe their behavior and adjust their location accordingly. If you notice that the leaves are becoming faded or scorched, it may be a sign that they are receiving too much direct sunlight. In this case, you can try moving them to a spot with more shade or provide some form of sun protection, such as a shade cloth or umbrella.
On the other hand, if your coleus plants are not showing vibrant colors or are exhibiting weak growth, it may be an indication that they are not receiving enough light. In this case, you can try moving them to a location with more direct sunlight or consider using supplemental lighting, such as grow lights, especially if you are growing them indoors.
While coleus plants can tolerate morning sun, it is important to provide them with some shade and limit their exposure to intense midday rays. Finding the right balance of sunlight will help ensure healthy growth and vibrant foliage for your coleus plants.
