Hi Liz,
I use Azomite with bulb food in the fall and the spring. I have noted that my newer peonies have bloomed sooner, than my older peonies that had not been given Azomite. The pips on my peonies continue to increase in size during the winter, due to our mild weather here.
Presently, I have many plants that still have green leaves, and others that are going dormant. I spent some time clipping the dormant plants back today. I'll start the fertilizing process in the next few weeks, when our weather gets cooler.
