Q.Non-flowering Sugar Snap Peas
I have beautiful sugar snap peas trellised in raised beds. I planted in February and they are thriving. NO flowers have formed on the plants. They were planted using an inoculant for peas. Only organic compost with rock dust mineral has been added. I would think I would see the plants flowering by now.

If they are healthy but not blooming, they likely do have too much nitrogen. Give them some phosphorus to balance them back out. Bone meal is a good source of phosphorus.
