It could be overwatering? With Adeniums based on where you reside (climate) and conditions made available. This is a process in which adeniums go through (loss of leaves, dormancy). Especially during this time of year, with lower light levels and temps. You are the only one that will know whether you have overwatered. Do not know that active ingredients in your ant killer and am not informed enough to give an answer on this. As tapla mentioned, with information given. Can make it a difficult to pin point. If you search at the bottom of the Adenium forum thread there is a bar in which you can search out most queries. The information and articles that Tapla has created about soil, water retention and such are very helpful and worth a read. We are fortunate to have very knowledgeable people here, so please check these out. This post was edited by rcharles on Sun, Nov 30, 14 at 15:22

I'll take a stab at this. I think it's just stress from having been moved around a lot. You don't know the conditions it has been through. Perhaps some roots were damaged. I think it just needs some time to get established. Don't over-fertilize. Make sure it gets good growing conditions. Don't let the soil get overly dried out, since it's in growth mode. Not sure what else to say. Hopefully someone in your area can offer some more help.

Do you have a picture of the seedling(s) in question? I am new at growing from seeds, and mine are all less than a foot tall. But the very first leaves they grew (which are now the lowest down) have yellowed and/or fell off. Might check a couple things though (in general)...how dry/wet is the soil? Better on the dry side than the wet, as plumies don't like "wet feet." (soil that's too wet/no drainage). Check the stem for softness (the firmer the better, otherwise could be root rot). Hope this helps... Mark

Hello Dennis and welcome to the forum. It's sad that you lost the big plant to rot, hopefully with everyone's help we can prevent that from happening again. It's a struggle to keep these plants looking pristine and mine have been through some really tough times believe me! I started growing them in 2004, from seeds off eBay and this year I have witnessed my first flowers to form properly and not drop off in the early bud stages like in previous years....though it would never happen! Now my second plant is about to produce blooms in the next week or so. The first plant is pink, the common colour and this second one is well on its way to be a white or some other very pale colour. I gave 8 from seed, 3 obesums and 3 Arabicums, plus two gifts, both obesums....but I've lost count of the ones I've lost, these 8 are now doing the best of all :-)) My plants are grown hard, they don't have any great size to them, but are short, stout and rather leafy with good hard caudexes. My mix is small bark chips, alpine gravel, seived perlite and general purpose bagged potting compost in roughly equal amounts. I can't get the turface,scoria and other ingredients a lot of the US growers use, so I have to adapt. I use Chempak 8 fertiliser once a week having been advised its a good alternative to the Dynagrow foliage pro that again, a lot of our American growers favour. If it's particularly sunny and they look/feel dry as in the past few weeks I use just plain water in between. The trick is to keep them on the dry side in winter as cold and wet=rot, (but sadly you know about that bit), and treat them as tropicals in the summer by watering more frequently. They can take a fair amount if water.....if they drain fast and properly, that is vital. Your pots are very attractive but I'm wondering as they fit rather tight, how do you water them? Do you water from a ve and then lift them out each time to drain fully ......as they certainly won't appreciate sitting in the run off? Others have mentioned that the small ones are over potted and yes I also agree. They will be far happier in a smaller pot. The other info you gave been given is good sound advise, please do come back again if you are unsure or need any more info, we like to help if we can. Goodness knows, I've asked for plenty of help in my time here! Gill.
