  1. Plant nectar flower mixture/wildflower strips

    A study in 2009 on a peanut-cotton farm in Georgia, USA (Tillman & Carpenter 2014) reported that tropical milkweed Asclepias curassavica plants placed between peanut and cotton fields were used by monarch butterflies Danaus plexippus. Milkweed plants were visited by 0–0.03 monarch butterflies/plant/observation. Monarch caterpillars were also observed feeding on milkweed plants and developing in to pupae. In 2009, four plots (23 × 61 m) were established between a 10-ha peanut field and 9-ha cotton field (each planted in May). Two weeks before cotton bolls appeared, 25 potted, greenhouse grown, flowering tropical milkweed plants/plot were placed 1.2 m apart along a 1-m-wide strip of bare ground between the crops. On eight days in August 2009, each milkweed plant was observed for 15 seconds/day to record adult monarchs feeding on the flowers, and the presence of caterpillars was noted.
