Spraying your roses off with water a couple of times a week will help reduce the aphid population. If a colony has gotten started, use Bayer Rose Spray or Safer Insecticide once a week per bottle instructions to wipe them out.

When the weather gets warmer, the dreaded Thrips will appear. They attack the rose blooms and turn them brown. Using a small plastic spray bottle, spray the buds directly with your chosen insecticide above, as they begin to open. Do this at least once a week.

Mildew can be kept in check by using a good fungicide. It is best to apply fungicide as a preventative for mildew on a weekly basis, rather than waiting for the problem to show up. It's harder to prevent damage once it's started.

70's water every 5 - 6 days.

80's water every 4 - 5 days.

Your roses should be receiving 10-15 gallons of water each time you water. You can calculate this by the size of the emitter (e.g. 1 gal/hour) x the number of emitters x duration of watering cycle) This should provide water to a depth of 18-24 inches deep, keeping the soil moist but not soggy. The soil should not dry out between waterings.

Continue to water your roses and increase the frequency to three times per week as the temperatures increase.
