About two years ago a friend of mine gave me a Hoya that was in very sad shape. It had one leggy stringer with some shriveled leaves, the soil was a solid ball of concrete hard clay. I honestly did not think the thing would survive. I repotted it in some typical potting soil mixed with a bit of peat moss and perlite, popped it in a west facing room with tons of sunlight, but no direct sunlight, and hoped for the best. To my astonishment it lived! Since then it's put out quite a few new runners and leafed out. The problem: every leaf is curled slightly and has a shriveled look like it's not getting enough water. At first I wasn't too concerned, but now, 2 years later, I'm beginning to wonder if there is something wrong. The new leaves are shiny and healthy looking. I've checked the roots, they seem plump, no burns or rot that I can see. Besides the original leaves there's no leaf burn. I had some of those fungus gnats last year, but those have been taken care of. I live in Colorado and have a horribly low humidity, but I mist it often. Fertilize once a month in the spring summer time. Water once a week until it gets hot enough that it dries the soil faster, then I bump up to a five day water cycle. Ideas on why The leaves are looking like this?
