Should I water it or leave it alone?
Saturday Garden Question:
It's getting colder, the growing season is ending, and your plants aren't actively growing the way they were in July.
So you can stop thinking about water now, right?
Not necessarily.
In much of the dry West, winter plant damage isn't always caused by cold alone.
Dry soil can be part of the problem too.
Trees, shrubs, perennials, and especially newer plantings may still need moisture during prolonged dry periods.
But that doesn't mean watering automatically.
Check the soil.
Consider recent rain or snow.
Look at the forecast.
And remember that a plant using less water isn't the same thing as a plant needing no water.
Sometimes winter plant care isn't about doing more.
It's about knowing when something is actually needed.
Have you ever lost a plant over winter that looked perfectly healthy going into fall?
For readers who ask for specifics in the comments, CSU's Colorado guidance is particularly useful: during prolonged dry periods without snow cover, water when air and soil temperatures are above about 40°F, preferably around midday so moisture can soak in before nighttime freezing. Newly planted trees, shrubs, and perennials are particularly vulnerable.
