Last time I posted here, I was recommended to fertilize with an azealea fertilizer since curry plants like alkaline soil. So I bought Azealea Miracle Gro and followed instructions and fertilized. Could this cause the leaves to turn black around the edges. Prior to that I used an all purpose fertilizer one mixes with water. Could the two types of fertilizers used so close apart caused this? I just now watered it heavily in its pot to rid of the remnants of the fertilizer if this was the cause. Could this help? Thanks for your response.
