May: When the purplish-red leaves have turned green and the buds are pea sized, mix your pesticide of choice according to label directions.
Add the following ingredients to each gallon of insecticide solution: 
- (1) one tablespoon epsom salts
- (1) one tablespoon apple cider vinegar,
- 1/2 teaspoon (.08 ounces or 3ml) Monty’s orange label (2-15-15)
Make sure leaves are sprayed from the underneath side as well as the top. Always add Monty’s when water is applied to your roses.
As temperatures warm into the mid 80 degrees watch for spider mites. These critters crawl from the ground up the stems of roses onto the underside of leaves and suck the chlorophyll out of the leaves. It is essential for the vigor of your roses to have healthy green leaves. Mites do not like water. So using a hose and sprayer nozzle wash through the leaves, particularly from the bottom up of your rose plants twice weekly. This is another good time to feed your roses through the leaves by adding Monty’s Liquid Plant Food.
