Rose leaves are dying - black spot? Hi. I'm brand new (to gardening and also to this forum),...
Hi. I'm brand new (to gardening and also to this forum), and hold a new rose bush call "Golden Masterpiece Hybrid Tea." I don't see a latin name. I've be looking around and think it may enjoy black spot? It has spots. They are black. It didn't purloin too long to come up with that, but how do i know? And what do I do? Can I dispatch pics on here? I uploaded some to flickr:

Any help is appreciated! :)
Answers: Actually, that picture shows that you hold an insect that is ingestion the buds. So you may have more than one problem - at hand are special formulations in the garden shop that will minister to for molds and for insects. If the leaves are turning yellow and black and falling rotten - then that is to say black spot, one type of fungus. Because it is humid and warm here surrounded by the South, I treat my roses and redtips for blackspot by limbing them up and keeping the leaves off the lower piece of the canes - black spot is soil-borne, so precipitation water splashing support off the ground is how it get onto the plant, normally. Once you enjoy it in upright health, try to stay ahead of it by going away the canes for a moment taller (about 30-36") and removing leaves that form below this height - that will bound the amount of this is gets contained by the future.
Take the leaves past its sell-by date that have black spots and vigilantly throw them away without dropping any around the plant. Treat the rose near a fungicide -- Ortho makes a dutiful one for roses. If you caught it early you can stockpile your rose.
