Phaseolus vulgaris 'Pinto'
vegetableThe classic Southwestern U.S. and Mexican bean. Mottled tan-and-brown skin when dry becomes a creamy beige when cooked. Earthy, creamy flavor that is the backbone of refried beans, chili, and many Mexican-American dishes. Easy bush bean that grows well in hot, dry climates that challenge other legumes.

When to Fertilize
Inoculate seeds with rhizobium before planting; no nitrogen fertilizer needed
Fertilizer
Low-nitrogen compost worked in before planting; no additional nitrogen
Direct sow after last frost when soil reaches 60 F. Pinto beans are bush-type, growing 18 to 24 inches without support. They are well-adapted to hot, dry conditions and produce well even with minimal supplemental watering once established. For dry beans, leave pods on the plant until brown and papery. Pull whole plants before fall frost and dry under cover if needed.

Proactive ways to stop trouble before it starts — tap a name with an arrow for its full guide
Row cover early season; neem oil spray; handpick beetles and larvae
Insecticidal soap; introduce ladybugs; water spray
Pyrethrin spray if severe; row cover early in season
Good drainage; avoid overhead watering; ensure spacing for airflow
For dry beans: leave pods on the plant until fully brown and rattling. Harvest before heavy rain causes re-wetting. Thresh by beating dried plants against the inside of a barrel. Winnow on a windy day. Dry beans store 2 to 3 years in airtight containers. Must be fully cooked before eating.
Excellent source of plant protein, fiber, folate, iron, and magnesium. Classic pairing with corn creates a complete protein. Very high in resistant starch that feeds beneficial gut bacteria.
