One of the trademarks of living in Idaho seems to be wind. Learning how to
adapt can be challenging to any newcomer. Unless you are from, say,
Chicago? In any case, being aware of how wind affects your landscape can help
in protecting them during our often dry, windy fall and winter seasons.
Drying winds strip plants, turf, and the soil of much needed moisture. As the wind blows it wicks the moisture out of the plant, and the soil. As the low humidity and wind blow, plants can’t replenish the water they lose through their leaves, or needles. This is one reason you may have a brown cast on the edge of your evergreen needles.

There are several things to keep in mind about your landscape if you live in these windy areas.

1. Fall and winter watering is not an option. Failure to water your plants is the most common cause of plant stress I see in landscapes. And just because your landscape is mature, does not mean you can stop watering it. You don’t stop drinking water just because you've matured, do you?
2. Mulch can help retain moisture in the soil. Yes, I know,
it’s windy and the wind blows your mulch all the way to Kansas. Well, I am sure
the people of Kansas appreciate your contribution to their fine state. Really
though, mulching can make a big difference in how much water your soils will
hold.
3. Add organic matter to your soil. Incorporating 2-3 inches of plant based organic matter at a depth of 4-6 inches will help hold in water
if you have sandy soil, or help water drain if you have clayey soil. Either
way, adding organic matter such as composted plant material will benefit your
plants. Just be careful if you use animal manure as compost as these contain salts and heavy metals that build up in the soil over time, and can increase the risk of food borne pathogens if used improperly in vegetable gardens.
