Plantlover2, can you post a photo for Dr. Houseleeks? It will help with the diagnosis.

Meanwhile if you could answer these questions it will speed things up in determining the problem.

1. How long have you had the plant?
2. Where do you live, as in weather conditions.
3. Did you acquire this plant as a potted plant or bare root.
4. When did you first notice the problem?

Had the plant for a week
Conditions are nonstop rain
Plant was potted
I noticed this yesterday, a week after I got the plant

I can try to get a photo but the plant's leaves simply turned transparent and it doesn't look good

What are your day time temps like?
Do you live in a hot area of the US?
How much sun is it getting?
What type of soil is it planted in?

Temps are mild, lows 30 high is 80 throughout the year usually cloudy

Area is not hot, it is very rainy

It just turned summer so we should start getting sun, we don't often because it is cloudy during the winter

Soil is unknown, was originally for sunflowers but I moved the sempervivums to a rockery instead because the soil was soggy

Soggy soil will definitely kill semps.
Good heavens, where do you live with weather like that?

Plantlover2

North western Washington. It rains just about everyday, we have sun today for the first time in weeks! I moved the plant to a rocky area and put some cactus soil around it. For some reason another sempervivum is having problems, it looks like something was eating it's edges away.

Could my plant be rotting from bad weather? If so will it live? I moved it as soon as I noticed...

If you are having lots of rain and the leaves are turning transparent, then it is likely the plant is rotting. Please post a pic right away.

If it is rot, it spreads rapidly and can kill the whole plant. A whole plant can rot within a day or two.

Emerald Giant is susceptible to rot. I grow them and they are generally an easy semp, but don't like to be disturbed much when wet. I myself have lost plants of Emerald Giant to rot. They can get very large, over 8 inches.

Generally the cure for rot is to dry the plant out immediately. This can involve digging it up and putting it some place where it will get air flow and no more moisture. I am reluctant to tell you to do that until I see a pic, but digging and drying a healthy semp should not hurt it if you are gentle.

Do what you can to protect from more rain. If you cannot get a pic right away, you may want to consider digging it up, moving it to a protected spot (leaving it out of the ground for a few days) and drying it.

I did dry it out and moved it to a rockery. I will post a pic soon, I just took the pic and need to upload it. It doesnt appear to be rotting fast but I am still concerned.

here is pic 1. most of the original leaves were plucked off because i didn't know if it would spread. it is a lot smaller now.

Awww, how sweet. The doc will be with you soon. But looks like you've caught it in time.
He will give you further instructions. He has helped me save several of mine that looked like that.

I just didn't realize how badly the rain could hurt them. I also have a few other types that I got about a month ago but they are fine. I wonder why these new ones took it so hard.

Many times the ones you get in pots have been fertilized to push growth. I have found that they don't hold up as well when stressed (to much rain, transplanting, to much sun, etc).
Doc will be able to give final instructions when he returns from his many treks. Smiling

...back from the stars...

Sue, as long as the rot does not progress to the stem, the plant will recover. The later pics look pretty good, so I think you have it under control. Be sure to watch closely. I'd pull off all of the leaves with rot and keep the plant dry, then look at least daily to see if more leaves are having problems. Be gentle with them and keep them on the dry side as they recover. You had some close calls there. I've lost a number of semps to rot very quickly, sometimes it seems almost overnight, to rot that I didn't catch right away.

Just last week I had a two headed Jovi heuffelii lose one of its rosettes to progressing rot. I had to dig it up to dry it out, then had to cut off the rotting rosette to save the other rosette. During hot spells in the weather, we should watch the plants closely. Once your collection is well established, however, you can relax a little bit as you can lose a few plants to rot and still maintain the variety.

Gah! It rained again! I'm bringing the emerald giant inside, the ground is soaking and it won't stop raining.

We are also back to clouds with an occasional shower. Later this summer we will be in a drought period and I will be wishing I had some of this rain. Whistling
Right now not so much. I want tomatoes this year. Come on sun. Both me and PlantLover need it. Hurray!
