Begonias are incredibly versatile plants when it comes to light conditions. They have the ability to thrive in a wide range of light intensities, from full sun to shade. However, the specific tolerance to full sun can vary depending on certain factors such as the climate and the variety of begonia.
In colder climates, begonias can generally tolerate more sunlight. The colder temperatures help to protect the leaves from the potential damage caused by intense sunlight. In these regions, begonias can be placed in areas that receive full sun without much concern.
On the other hand, in warmer regions, begonias require some protection from the hot afternoon sun. Excessive exposure to intense sunlight can lead to leaf scald, which causes the leaves to become discolored, brown, or even scorched. To prevent this, it is advisable to place begonias in areas that receive partial shade during the hottest parts of the day.
When it comes to the foliage color of begonias, it can also play a role in their tolerance to sunlight. Varieties with darker foliage, such as bronze or burgundy-colored leaves, tend to have a higher tolerance for sunlight compared to those with green leaves. The darker pigmentation in the foliage acts as a natural sunscreen, providing some protection against the sun’s rays.
Personal experience-wise, I have grown begonias in both full sun and shaded areas. In a colder climate, I have successfully grown begonias in areas that receive direct sunlight for the majority of the day without any issues. However, in a warmer region, I have noticed that begonias placed in full sun tend to develop leaf scald, especially during the peak summer months. To mitigate this, I have moved them to areas with partial shade, and they have thrived without any signs of leaf damage.
While begonias are generally tolerant of a range of light conditions, their tolerance to full sun can vary depending on factors such as climate and foliage color. In colder climates, begonias can withstand more sunlight, while in warmer regions, they require protection from intense afternoon sun to prevent leaf scald. Varieties with darker foliage have a higher tolerance for sunlight compared to those with green leaves. It is important to consider these factors and provide appropriate light conditions for begonias to ensure their optimal growth and health.
