"Don't put your plants outside until after Mother's Day"

[William Seger]

That was the advice we got when we moved to Colorado Springs, and most years it proves to be true, if not too early. This morning, we woke up to two inches of snow, and it's still coming down!

1. 5 inches (much more likely since the ground was so warm it took a lot to stick for the current

4-5 inches)--northern Colorado.

I always tell newcomers to wait until after Memorial Day. They scoff, but I have been proven right far too many times that they don't do it more than once.

3. A few years ago, we had a warm spell in May.

My sister, who is an avid gardener. decided to plant her entire vegetable garden. She starts everything from seed, indoors. It was a big garden. One night, the weather went from warm to 36 degrees. Everything died. It looked like a massacre. Since then, she waits until after Memorial Day.

4. I always ask for Ivy Geranium hanging baskets for Mother's Day

but it's perfectly fine for the hanging baskets not to be purchased until about Memorial Day or so.
