When I did ran a landscaping company, this is what my horticulturist partner told our clients: If the chinook is extended, a tree(or shrub or even a perennial) will think spring is here and start to grow. Make sure it has some water during these times. As for your grass, same basic concept, but since grass gets alot more water from snow in ratio to what it needs, unless the chinook is long you wont need to consider it.


Grass is pretty hardy, I have planted sod in the middle of January and had it come in strong the next year. The main concept is if the plant is dormant, it doesnt really use anything, but if it starts to grow, the plant needs alot of water and if it cant find it, that is when the most damage can occur.
