Snap beans, also called green beans, are grown for their edible pods. There are both bush varieties and pole varieties. Pole types of beans require a trellis or stake to support their climbing vines, while bush varieties are compact and upright, requiring no additional support. Snap beans are a warm-weather vegetable that requires minimal maintenance after being planted. Plant them in the garden in spring two to three weeks after all danger of frost has passed.
Choose a garden bed in a full-sun area that is well drained and not prone to collecting water.
Prepare the garden bed for planting after soil temperatures reach 70 degrees F. Lay a 2-inch layer of mature compost over the planting bed and till it into the soil to a 6-inch depth. Compost aids drainage while also providing organic matter and nutrients to the soil.
Sow bush bean seeds 2 inches apart in rows that are 18 inches apart. Sow pole beans 1 to 2 inches apart in rows 2 to 4 inches apart, placing a trellis or other support between each row for the vines. Plant seeds of both snap bean varieties to a 1- to 1½-inch depth.
Water the garden thoroughly immediately after planting. Provide approximately 1 inch of irrigation per week, with more frequent watering necessary during drought periods.
Weed between the bean rows until the plants germinate, approximately four to seven days after sowing. Apply a 2-inch layer of mulch around the plants after they are 5 inches tall to alleviate weed problems as the plants continue to grow and mature.
