How is there a dry spot on the fleshy leaves of Swift constellation?

Swift, a succulent plant of Lycopodium, is one of the succulent plants in the constellation system. Its leaves are slender, thick, oblong, slightly concave, with curved back, no ridgeline, oblique tip at the front, slightly twisted and short tip, four seasons red leaves, standard rosette shape, and the whole plant is covered with frost. Usually, the color of leaves is blue-green or tile blue.

Swift is a kind of succulent plant. I have two pots of swift, which are more than 25cm in Ye Zhan. They all grow their own leaves and have been raised for about 5 years. Swifts are very strong and easy to raise. Generally, they grow silently, don't pay much attention, and it's not easy to grow in vain. It is difficult to see the sudden rise of the stem unless it is kept in an environment with insufficient light for a long time. The most important thing is that its face value is not low. Basically, the red edge will not fade all year round, and even half of the leaves will turn red when they are not in the state, which is very beautiful. It is a succulent variety worth having.

Swift constellation has thick frost on its leaves, so it is more resistant to the sun. Even if the temperature reaches about 38℃ in summer, I don't have any sun protection and I don't see any sunburn. The picture below shows that there are many spots on the leaves of my Swift constellation, not sunburned, but injured when I broke the flower arrow. Before this, its plant shape was very compact, and the flower arrow had not fully grown. It took me a long time to pull it off with tweezers, and then I hurt the leaf.

The spots on the leaves of this Swift seat may be sunburned or other abrasions and scratches. It's not a bacterial infection anyway. Although it has a little impact on the face value, it will not affect the normal growth of Swift seats. Subjects can leave it alone and consume it slowly later. The subject may have questions: Isn't it that Swift is very sun-resistant? How can you get sunburned? Under normal circumstances, swift is indeed sun-resistant, but if the leaves are exposed to the sun when they are full of water, the leaves will be sunburned, and then partially hydrated and moved to a cool and ventilated place in time, but the leaves will still be sunburned, as shown below.

Another thing to note is that Swift is sun-resistant, and what I'm talking about is based on long-term exposure. If any meat lover hears me say that Swifts are sun-resistant, he will put the Swifts he has raised for a long time indoors or on the balcony in the open air, and then wait for the pots to be collected-if it is about 38℃, it can be directly dried in water, and it will rot within 1-2 hours. So generally speaking, when the temperature exceeds 35℃ in summer, it is best to shade Swift, control water and strengthen ventilation to help it spend the hot summer smoothly.
