Pole beans are an abundant produce of snap beans in the home garden. They take up minimal room in garden beds, often being planted on the north side of beds so other plants can grow in front of them. Growing along poles or trellises enables easy harvest of the beans since they are easily accessible from all sides of each vine. Caring for your pole beans properly ensures they remain productive and healthy throughout the growing period.
Water the garden bed once a week, providing approximately 1 to 2 inches of water each time. Water more often during hot, dry weather or if the soil begins to dry out. Water in the morning so any water that gets on the bean leaves can dry before nightfall, which helps prevent disease.
Weed between the pole bean plants, particularly during the first six weeks after planting. Pull weeds by hand and break up the top 1 inch of soil around the plants with a hoe to inhibit weed germination. Avoid breaking up the soil too deeply as this may disturb the shallow roots of the pole beans.
Lay a 2-inch layer of straw or bark mulch around the plants to help inhibit weed growth and preserve soil moisture. Lay down the mulch once the bean vines are beginning to twine around the trellis or support.
Fertilize when plants begin producing pods if the pods appear yellow-tinged or are not forming well. Apply 2 lbs. of nitrogen fertilizer per 100-foot row, working it into the soil 3 inches from the base of the plants.
Inspect the underside of leaves and the vines of each plant weekly for signs of aphid or insect infestation. Signs include visible insects, leaf discoloration and damage. Wash aphids off the plants with a sharp spray of water or treat aphids and other insects with an insecticidal soap.
