Since we are reminding people about spring chores (Amonia thread) I got to thinking about mine.
I'm typing up my pip count spreadsheet. Last year one of you forum regulars said you kept track of your pip count each year. If the pip count is down, then you know there could be a problem, like root invasion, voles or rot. I can't remember if said person dug it up right away or if he/she waited and dug after two reduced years.
Anyway, I think its a good idea to help diagnose problems below ground.
