Hello, I live in San Diego CA and I always enjoy reading this forum.
This time, I'd like to ask some advice for my hoya kerrii. I purchased this 2 months ago with 3 bottom leaves and 2 leafless stems. I hang it with my other hoyas in my backyard, bright indirect sunlight. It was doing good until today. The soil is a mixture of orchid soil, bark. leca and perlite. Since it been hot and dry lately (90s) I water them every 4 or 5 days. Today, I was surprise to see a big spot in one of the leaves. I must have not notice it yesterday since I check on them almost everyday. I immediately sprayed it with Bonide ready to use liquid copper fungicide thinking it was cause by fungus. will this save my plant?
