I have a s. alata that is fairly 'old'. I'd say about 8-10 years old. It's soil is composed of straight peat. I got it this way from a nursery earlier this year. I decided to divide it earlier this year and did so with a fair amount of sucess after debating the whole thing for some time. I put the divided plant in a mix of about 50/50 peat and sand. It is at my neighbors house for he loves these things but wants an easy plant to care for. That plant is doing exceptional, and the others that were left in the all peat mix are just kinda blah. Now I know that stress is a factor here and yeah, the plant at my neighbors house gets about 45 mins more sun, but could this be a case of soil exhaustion? same plant and the only real difference that I would connect would be the soil composition. I do not know if this plant has ever been repotted except for what I did. I am curious to know what everyone thinks. I will be repotting here soon. thanks...
