I'd say yes! Peanut butter is probably one of the most-acid inducing foods because it is primarily fat. It requires more energy to digest (just like any other fatty food), which requires more acid to do the job. Lay off the PB, and switch to a low-fat carb-based diet. Simple sugars are easily digested.
Japanese millet is most successful when planted on prepared soil, although Japanese millet will germinate and grow just about anywhere. For Duck food plots, plant the Japanese millet early in the summer (June-July) depending on the start date of your duck season. Japanese millet seed heads will hold on longer than most millet varieties, even in standing water. The seed will slowly drop out of the seed head feeding the ducks over time.
Germinate Peony Seeds. Collect peony seeds from plant pods when the pods begin to open and seed coats are dark. The best time to collect is between July and September depending on the variety and climate. In dry climates, maturing happens earlier. Place the seeds in water for several days. Change the water daily to prevent disease. Remove seeds that are rotted or mushy.
