My succulent is growing leggy and its leaves are wilting - is it lack of water or overwatering?

Newbies who have just started growing succulents always have a million questions. Some symptoms on the plants are hard to identify, so taking photos for an expert to check is the most direct way. Below we continue answering questions from succulent growers.
Question 1: Is this 'First Love'?
Answer: Yes, it's 'First Love'. Treat her well~
Question 2: How should I deal with this one that has grown top-heavy? I haven't watered it much, and it has always been on the balcony. Is it called Thousand Buddha Fingers?
Answer: Yes, Thousand Buddha Fingers (Sedum pachyphyllum). Even on a balcony behind glass it will still grow leggy. It's getting hotter and hotter now, so I don't recommend pulling off leaves or beheading it; if you do behead it, that's fine too - it has already sprouted small heads below, and once the wound on the upper part has dried, you can place it on moist soil to root.
Question 3: How does Black Prince branch?
Answer: Black Prince (Aeonium 'Zwartkop') is usually propagated by beheading once the side shoots grow to more than ten centimeters!
Question 4: Why are the leaves of my Sedum growing downward? How should I care for it now? Thank you
Answer: It's lacking UV exposure. Just gradually increase the light.
Question 5: Hello, what's wrong with this?
Answer: Sunburn. Mine has even more sunburn than yours~
Question 6: Why have the leaves of my Sedum 'Burrito' wilted? I've been watering normally lately. And that Laura, when I bought it I smelled it carefully and it had a fragrance, now it doesn't.
Answer: If you're watering normally, maybe you're actually watering too little? Hehe~ For fragrant succulents like Laura, the more sun they get, the stronger and more noticeable the fragrance becomes. I guess the windowsill doesn't get enough light~
Question 7: Is the one on the right growing too tall? A bit leggy? What's its name?
Answer: A leggy Coral Beads.
Question 8: Help, what's wrong with my Moon Shadow? Why is the Ruby Necklace dropping leaves? And what is that plant called? It has always been under the east-facing window, with ventilation, but it got rained on last weekend, so I stopped watering. How should I get them back to health now? Thanks!
Answer: The fuzzy one is called Felt Bush. The root systems of the Felt Bush and Moon Shadow should be fine. Water when it's time to water, and clean up the dried leaves to prevent mold and bacteria from growing when you water. No need to say more about ventilation.
Question 9: Please help me take a look. My Fire Cracker grew leggy so I beheaded it, but that head is always wilted? Why is my Fire Cracker green instead of red?
Answer: The wilted beheaded part means the roots haven't established well yet! Succulents changing color, what we call "coloring up," generally happens in spring and autumn when the day-night temperature difference is large. Now in summer the temperature difference is small, so naturally it won't turn red!
Question 10: I have a Romeo that just won't root no matter what. Earlier when the weather wasn't so hot, it grew roots about 1 millimeter long, but now it's probably too hot, the roots it grew have dried up, and then there's been no movement. What should I do?
Answer: When rooting, the soil must be moist - neither too dry nor too wet is recommended. The environment must avoid direct harsh sun; newly grown roots can't tolerate high temperatures. Although it's hot now, don't lose heart. Continue with moist soil (sprinkle some water in the evening or at night when the soil is dry), ventilation, and bright indirect light or half-day sun in the morning and evening to encourage rooting.
