OH YEA Doris, those worms will be HAPPY
For those in the colder zones you may not want to add alfalfa or whatever until spring since you may not want your daylilies trying to grow when they may be wanting to get ready for winter. I have heard that most people in the colder zones do all their fertilizing and what have you in the spring because of this.
I was digging daylilies today to divide and my friend Kim said look there's a baby snake so I looked. Guess what, it was a big, fat worm
I had to laugh at her. My worms are very happy.
Ann, yes the ground alfalfa has the same effect, maybe even faster since the worms can eat it better since it's ground up for them
