I've done a lot of experimenting with alcohol and my IBS-C, the bad news I'm afraid is that I really don't drink much anymore because NOTHING in the world is worth the IBS-C symptoms for 2 weeks afterwards (same as you).
Peas don't thrive in hot weather; they grow best in spring and summer when daytime temperatures average between 60 to 75 degrees. When selecting a seed, look at the varieties' days to maturity and plant early enough so that harvest will be complete before daytime temperatures consistently hit 80 degrees.
If you are going to grow black-eyed peas in a container, you should stick to bush varieties and your pots should be around 12-inches deep with very good drainage. Soil in a container will dry out faster than outside garden soil, but you still want to make sure you are not over-watering your plants.
