Cactus ID please
I've recently added three plants to my collection. Two are succulents and one is a cactus. Pictures can be seen here. http://www.flickr.com/photos/upload/done/ My guesses are as follows.
Green succulen - aloe or haworthia
Yellow cutting - crassula or sedum
Cactus - ?
Also, you can see that some of the lower leaves on the green succulent have rotted. A couple of days ago they only had a few little spots. It's been really humid lately. I'll remove the leaves, but does it look like the plant is sick enough that I should try and take a cutting? Or is it likely to be okay? Thanks!
