Rose Problems

You have a couple of problems here. The leaf damage is done by the rose slug bud worm. This larvae (tiny green worm) eats on the underside of the leaves leaving the top tissue in place. It is active from early June into about the third week of June in the northeast. The pest is probably gone now but make a note to spray the underside of all of your rose bushes with a product containing Spinosad next year in the first week of June. One application should be enough but you can always reapply in the third week of June if you see new damage.

Rose flowers that look like this have usually been hit with too much water/irrigation. It’s a fungal condition but the fungus (most likely botrytis) happens in cool and damp conditions. Are your roses being watered with a sprinkling system that comes on more frequently than once every four or five days? Are you watering at night or really early in the morning? Or are you hand-watering by spraying the plant and not the soil? Apply an organic fungicide such as copper, sulfur or one of the bacterial products like Serenade or Actinovate. (Use according to directions) and alter watering appropriately. Water deeply less often.
