Understanding Disease Resistance in Zone 8 Plants

Gardeners in Zone 8 face unique challenges when it comes to plant health. One of the most important factors for a successful garden is understanding disease resistance in plants suitable for this climate zone.

What Is Disease Resistance?

Disease resistance refers to a plant’s ability to prevent or withstand infections caused by pathogens such as fungi, bacteria, and viruses. Resistant plants can either avoid infection altogether or limit the spread and severity of diseases.
