If you ignore Grand Junction and La Junta, most of Colorado normally experiences the first frost of fall sometime in late September or October. And yet, it’s October 27 and there hasn’t been a fall frost. Weird. Colorado is definitely unpredictable.
So what does this extended fall mean to our landscape plants? Here’s a short video where I address that very question.
The golden nuggets from the video are the following:
- The extended fall has allowed plants to go into dormancy gradually. This is pretty unusual, but a good thing for most of our landscape plants. Most of the time their dormancy process gets rudely interrupted by dramatic temperature changes in fall.
- Those plants that haven’t yet gone into dormancy are still using water. It’s important to make sure your soil is sufficiently moist so your plants don’t dehydrate and possibly die. Our plants are using more water than they normally do in fall because they’ve retained more leaves than usual.
- The last week of October is a great time to fertilize your lawn one last time. Go here to learn more.
Here’s a nifty interactive map of Colorado that shows the average first fall frost. You can zoom in on your location and see what the average is. But remember, nothing in Colorado happens on the “average” date!
