Pinto beans are staples in Mexican dishes and southern U.S. cooking. Farmers and home gardeners grow these beans throughout the country. Southeast Michigan, with its long sunny days in the summer, has a good climate for growing pintos. Grow them on a trellis or up a fence through the summer and you'll be harvesting dried beans by the first weeks in August.
Dig the soil to a depth of about 6 inches in an area that gets at least six hours of sun per day. Mix in a 4-inch layer of compost. Smooth the soil to a flat surface.
Insert trellises or poles if the planting site isn't near a fence.
Plant the pinto bean seeds about 1 inch deep and about 3 inches apart. Water the ground until it is saturated.
Train the bean vines when they start to develop runners, which are little vines to hold the plant up. Wind the stem around the trellis pole three or four times to ensure that it grows in the correct direction.
Give the pinto beans about 1 inch of water per week. Make up any shortage of 1 inch of rain by watering with a hose or sprinkler.
Pay close attention to the plants beginning the first week of August. Pick all the seed pods when the leaves and stems are dried out and dead-looking.
Crack open the pods and remove the dried pinto beans. Package the beans in clean glass jars or other airtight containers to store them through the winter.
