Hi, Ive also been having some trouble out of my Adenium Obesum. But as I am looking through some of the suggested caused and cures. I am finding it a little hard to compare since there are a few differences. I purchased my Adenium Obesum about a month ago online. It arrive healthy, about 2.5-3" tall green and healthy. She was obviously grown from seed since she has the infamous fat trunk. I done a little research before purchasing the plant. I got to know it like dry arid conditions, fast draining soil, and PLENTY of sun light. I also read you could train Adenium Obesum to become indoor tolerant. My potting medium is bonsai potting mix, and sand; no course or dead plant material as it is highly susceptible to root rot. Since it has arrive I placed the plant in indirect sunlight but still pretty bright. After about a week or so I noticed a bit of yellowing in a few of the leaves. Come 2 days later it has spread to a few more, a few days later the first yellowing leaves begin to wilt. Then fall off. You get the idea. So now its a month later and I have a most of the original leaves, but a few have fallen off and most haven either yellowed or becoming yellow. I know my water is draining fast, the only thing I can think is light, or the water I am currently using (tap) is not kosher with my Adenium Obesum. Please help, I want to see my little girl thrive. I know Adenium Obesum are such BEAUTIFUL trees, which is why I purchased it to begin with. The situation isnt too dire, but until I get some help I have her placed outside my window in direct sunlight most of the day. Btw I am watering her about once-twice a week. Im still figuring out what she likes as far as water. Remember this is a baby not some of the beauts you guys have posted. Thanks once again, Stefan

How frequently should I water it? Thanks for the insight, that would make a lot of sense if it needs more water than other succulents.

Hi! I'm interested in your passion vine seeds. I have a lot of morning glory seeds (purple), some alyssum and verbena seeds (the annual sort, I believe) and a lot of pothos cuttings. I also have some medium-sized aloe plants. Any of those strike your interest?

t_bird, You will need to post a photo for accurate assistance. Without, Lichens will not damage plant and often black spots on trunk can accompany Lichens. This is all speculation. Question will also be where you reside (climate & conditions), site where plant is. Often Lichens are on shrubs/trees when they are in a low light and shaded area. Rick
