Choose disease-resistant plants for your landscape

Purdue University Extension suggests one of the best ways to prevent serious plant disease outbreaks is by choosing disease-resistant plants. Using healthy, disease-resistant plants in the garden or landscape minimizes, or even eliminates, the need for pesticides and reduces maintenance.
By using plant species, varieties or cultivars that are genetically resistant to diseases, buyers immediately implement the most effective and sustainable means of plant disease control in the landscape. Although most plants do not have resistance to many common diseases, incorporating disease-resistant plants in the landscape whenever possible minimizes the impact of certain diseases in the home landscape and potentially reduces pesticide use.

In addition to disease resistance, it is important to remember that proper cultural techniques will help prevent powdery mildew, rust and leaf spots.
Phlox paniculata ‘David’, a Perennial Plant Association
Plant of the Year, has good resistance to powdery mildew.
