2010 Peony Stem Counts

Wow! I just braved the midday 90+ degree heat (head index of 99 degrees) to start on my peony stem counts. This is going to have to be done a bit at a time because it is HOT out there! Counting the peony stems gives me a good idea of which peonies are growing and increasing well from year to year. It may also indicate whether they like their growing conditions. If they are not increasing well, they could have too much sun, too little sun, too little moisture, etc. Also it tells me which peonies I should be dividing this fall. I believe a good rule of thumb is if a peony has 7-8 stems or more, it is a good candidate for division. My intersectional peony 'Bartzella' actually increased from 10 stems last year to 17 stems this year, almost double!
