Sun Stress in Hoya Plant

The transformation of a hoya’s leaf from a glossy green to stunning blushes of burgundy or pink is an unforgettable experience.

It is important to ensure that your plant receives ample sunlight to see this amazing transformation. The hidden colors of your hoya are easily revealed with a little diligence, regardless of the fact that it sounds like.

A hoya that is stressed by sun requires care to be sure to avoid sunburn. The hoya should be steamed off to adjust it to the new level of light and keep an watch for any indications of burning or dehydration. If you are patient the leaves will show a reddish hue in their natural color.

What Does Sun Stress Do to Hoya?

Although your plant needs the sun’s rays for survival but the sun is an unforgiving mistress. The excessive radiation of ultraviolet from sun damage chlorophyll, which is an important pigment in the plant’s metabolism. The leaf’s structure starts to degrade in the process.

To counter the problem, hoya creates anthocyanin, which is a colorless compound. It is typically visible as a red or pink hue on your leaf.

Anthocyanin is a powerful antioxidant that blocks the harmful ultraviolet portion of the spectrum of light before it harms chlorophyll. It’s nearly as effective as sunscreen!

The way that this sun stress manifests on your hoya is largely dependent on the type of hoya. In the end, the family is comprised of nearly 300 distinct varieties!

Variegated hoyas display gold or orange variations to the lighter parts of their leaves, while plain-leaf hoyas gradually transform their leaves to rich reddish-purple.

A more ardent sun-lover may require full sun. While others might require just a few hours of indirect sunlight that is filtered to get the bronze shine.

Start by finding a secure and well-lit space to keep your pet. Even for hoyas that thrive in bright light direct sunlight is not the best choice. Choose the most indirect light your plant will endure.

A subtle flush of burgundy can be safe, but attempting to make the entire plant in burgundy could create issues in the end I’ve observed.

The direct sun’s rays weaken and kills leaves. They disappear at the conclusion of the season of growth in cases of less sized plants.

Keep in mind the different kinds of plants that you have and the type of light they prefer. Similar to humans tanning excessively tanned can cause harm.

Begin small, then gradually raise the amount of light until the plant starts to blush and it is secure.
