We’ve had unusually warm and dry weather in many parts of Wyoming this fall and winter. If this trend continues and brings with it our typical western region yo-yoing temperatures (warmer spells followed by deep freeze events), we are likely to see a variety of effects on plants as spring and summer roll around. Here are some issues you might encounter this spring and summer and what, if anything, you can do about them.

Possible effects:

  • Increased amount of winter desiccation (a.k.a. “winter burn”) on evergreen plants such as spruce, pine trees, etc., especially if the soil was mostly dry over winter. Newly planted trees and also those in wind-prone areas can be particularly affected.
  • Sunscald on the trunks of newly planted or thin-skinned trees.
  • Cold damage on newly emerged leaves, flowers, and stems.
  • No or little fruit on some fruit trees, due to cold-damaged flowers.
