How to Manage Pests

Pests in Gardens and Landscapes

Cold injury and frost damage

Cool and freezing temperatures may cause a number of symptoms. Plants may grow slowly or die. Pollination may be prevented, causing little or no fruit to develop. Fruit may be small, blistered, puckered (catfacing in tomatoes), and lack flavor or color. Leaves may be streaked, spotted, or wilted, and plants may flower prematurely, causing them to bolt. Plant to avoid cold and freezing injury. Cover susceptible plants when cold weather threatens.
