If you are spraying your roses, discontinue the spray program while the temperature is on the 90's. You’ll burn the leaves. When the temperature cools down, you can resume your spray program every 7-10 days. Spray early in the morning or early evening.
If you have blackspots, you might want to spray though it might be too late to control it now. With the high humidity, it is blackspot season. Blackspot known as Clean Air Syndrome in the plant world is rampant this time of year. Roses grown in industrial towns where air is too polluted don’t get blackspots.
Blackspot starts as tiny spore in the leaves and in about 3 to 5 weeks develops into a spot as big as a pencil eraser with a yellow band around it. If left untreated, leaves turn yellow and can defoliate the whole bush. The cure is to have a spray program regularly every 7 to 10 days. Bayer or Ortho systemic 3 in 1 (Fertilizer, insecticide and fungicide) is excellent. Neem Oil is another environmentally safe fungus control. If you don’t mind chemical, Manzate, Maneb, Triforine and Daconil are effective fungicides. But just like any other chemical spray, please read the label and follow the directions.
If you do spray, be very careful when spraying to keep the spray out of your skin, eyes and lungs. Wear a protective mask if at all possible without scaring your neighbor. Unless the situation is so grave, your roses will bounce back. Don’t worry too much about it!!Roses are easy plants to grow contrary to popular belief. Why do you think Roses have been around for millions of years? All they need are food, water and sunlight. Just like you and me.
