I planted Pinto Beans in my garden this year. But am not sure when to harvest them. I believe let them dry them then pick and shell. Can you give me any info on this?
If you want to have dried beans, just allow the pod to dry on the bush.
Then pick them and store in a cool dry place.
Does it matter if you use tap water or purified water to germinate pinto beans? Which works best?
Germinating pinto beans with either tap water or purified water is fine. There will probably be no difference or only a very small difference. Purified or distilled water is best for certain very sensitive plants, like carnivorous plants, but most plants really don't care.
