Euphorbia milii dropping leaves
Last March I kind of inherited a Euphorbia milii, about 1.5 feet tall. It was a bit beaten up, but otherwise okay, a lot of leaves missing from the bottom of the stems, but I understand it is a habit of this type of plant to drop the lower leaves. Soon after I had placed it to its new spot, it started growing and blooming and it has been in bloom constantly ever since. Then, about 3 months ago, I left for two weeks, leaving the poor thing to my husband, who forgot to water it, so by the time I arrived back 1/4 of the leaves were yellow and dropping. I do not completely understand this, because I thought 2 weeks without water should not be a problem for a succulent, but anyway, since then, I have been trying to save the plant: I tried to water it a little bit more, added fertilizer, then watered it less, but nothing helps, leaves are still dropping like crazy. I do not see any pests, discoloration or anything Ã¢Â" they just turn yellow, then brown and crispy... The funny thing is that at the same time the very tips of the branches are growing, new shoots are developing at the base of the stems, and the plant still has not stopped blooming, even though there are hardly any leaves left on it. In the past, it had short periods of dropping leaves, but never so excessively, and I managed to minimize the leaf loss by either adding more water or fertilizer. I also heard that Euphorbia is supposed to drop the leaves and then grow them back, but so far that never happened, new shoots and flowers do show up, but no new leaves on the stems.
Any thoughts on that? Is there something else I could try to save it, or should I just get used to my new, almost completely barren Euphorbia? :(
