Coleus dying, please help!!!
Hello, everybody!! IÂ´m in an emergency. I have a Coleus that has ruffled leaves with yellowish border and some red (I think its called fiery something, or something like that). A few days ago, I saw one of the stalks losing leaves and kind of drooping and I watered it, thinking that I may have let too much time between waterings, although the whole plant look fine, except this stalk. The next day, the stalk was black and dead. I cut it out and started checking closely to the rest of the plant, but I didnÂ´t see any significative difference in the two following days. Today when I came from work I almost fainted, now out of the four stalks remaining, 2 are drooping and the plant as a whole looks not so good anymore. What can I do? I changed the soil when I got the plant (a few months ago), but I donÂ´t know if there could be something there. I tried planting another cutting of Coleus I got from a friend (white center) and it died, also starting to get black from the part that is stuck in the soil. I donÂ´t over water, I only water twice a week if itÂ´s not too humid or cold (which is not yet here in Philly). IÂ´m worried there is something in the environment, and IÂ´m fearing for the rest of my plants. What can you tell me about this?? can somebody help? Are Coleus supposed to die? are they annuals or perennials? Will I lose my Coleus??
Please, please, help!!
