This time of year, it seems like we're still in limbo between winter and spring.  One day, it'll be in the mid 40's and the next, we top off near 80.

I look at my lawn every day when I get home.  It still looks dead but I can tell that some green is starting to poke through.  Does this mean I should start to water? 

Even if I wanted to, I can't because I live in one of many neighborhoods that uses a retention irrigation system.  I don't pretend to understand the mechanics but basically, storm water is captured by holding ponds throughout the year and that water is stored and later used in the neighborhood to irrigate.

So when should we start to water?  Dave Wright with Kimberly Nurseries has some suggestions.

Reminder:  If you irrigate in the city of Twin Falls, you have to stick to a weekly watering plan.

Even numbered addresses ending in 0, 2, 4, 6, 8 water on Tuesday, Thursday, and Saturday.
Odd numbered addresses ending in 1, 3, 5, 7, 9 water on Wednesday, Friday, and Sunday.
