Tips for pea seeds
I have great luck in the garden, but planted around a hundred pea seeds and I bet only 15 came up. I forgot to apply noculent, but I always have problems with peas rain or shine. This year has been rainy, so the cooler weather should have been great.

Unfortunately, this rain is what caused the issue. Peas are very sensitive to rot, and wet conditions will cause this. A dusting of wettable sulfur, or a mix of 1/4 peroxide and 3/4 water will help to guard against this, but this will also kill an inoculate. Adding this back in after treatment will negate this.
