I have one of my peony varieties that is getting within days of harvest and the stem is bursting apart right by the bud. I was wondering if this is due to weather (we have had a warm wet spring, resulting in earlier then normal season), or something else? So far I'm only seeing it on one variety, 'Many Happy Returns'. Ideally if I can find the cause I would like to prevent it if possible. On the off chance it has to do with the chemical products we apply, we have sprayed beneficial nematodes and Serenade fungicide, and will be applying Conserve SC VERY soon. Thanks for your time and consideration! LeAnne Lund
