Rose Tip #1: Do your research! Roses are rated on several characteristics. Choosing roses that are rated as resistant to fungal diseases such as black spot and powdery mildew should top your list.
Rose Tip #2: Roses require at least 6 hours of full sun (preferably in the morning), a well-drained and nutrient-rich soil, and moderate amounts of water. Water should only be applied directly to the root zone, not to the leaf surface. Adequate sunlight and water will help decrease the spread and incidence of fungal diseases.
Rose Tip #3: When pruning roses in early spring, prune with the understanding that opening up the center of the plant allows for light penetration and air circulation. Allowing light and air into the center of the plant will create an environment that is less favorable to fungal diseases.
Rose Tip #4: Eliminating dead, dying and diseased plants and plant parts from your garden will help to keep your garden healthy. This includes cleaning up potentially diseased rose leaves that have fallen from the plant. Fungal spores can overwinter and return to the plant from the fallen leaves.
Rose Tip #5: Not all bugs are bad! get to know the insects that visit your garden. Find out which insects truly pose a threat to the health of your plants (pests). Find out if the pest has any natural predators (beneficial insects). A healthy garden should have both. If necessary, you can introduce mail-order beneficial insects into your garden.
Rose Tip #6: Beneficial insects are often beneficial only at certain stages in their life cycle. For example, the syrphid fly only feeds on prey while they’re in their larval stage. Adult syrphids don’t eat other insects, they eat nectar and pollen. You should plant flowers that provide a variety of nectar and pollen sources throughout the growing season.
Rose Tip #7: Last one! Plant families that will help attract beneficial insects to your rose garden, including:
Apiaceae (or Umbelliferae) -Carrot Family- attracts lady bugs, parasitic wasps, and predatory flies.
Lamiaceae or Labiatae -Mint family
Asteraceae -Daisy Family- attracts hoverflies, lacewing, lady bug beetles, minute pirate bugs, and spiders.
