Green beans are the quintessential backyard vegetable crop, thanks to their relatively low maintenance nature and bountiful production of crisp bean pods. Provide your backyard bean plants with the specific growing environments they need, like adequate sunshine and harvest-boosting fertilizer, to optimize their growth and help them produce their pods as fast as possible.
Choose a gardening area. Green beans grow the fastest and healthiest when provided with lots of sunshine--a six hour minimum is ideal--and well-drained soil, according to Purdue University.
Wait until the soil temperature is a minimum of 60 degrees F, according to the University of New Hampshire. If the soil is colder than this, the green bean seeds germinate slowly and may experience stunted growth.
Amend the soil to provide the green beans with the soil nutrients they need to grow quickly and produce the greatest number of pods possible. Stir in a couple inches of aged compost--compost boosts the soil's organic matter content, increasing its fertility and helping it retain water--and follow with a 5-10-10 fertilizer. Purdue University suggests spreading the fertilizer at a rate of 1 cup for every 50 feet of bean rows.
Plant the green bean seeds, giving them adequate space to spread. Cramped bean plants will grow slower. Bury each bean seed 1 inch below the soil surface and 4 inches apart. If you're raising more than one row of green beans, space each row apart by approximately 2 feet, according to the University of Illinois.
Water the planting area twice daily until the beans germinate. Germination typically takes 10 to 14 days. Afterward, reduce watering to once a day. Apply enough water to moisten the soil to a depth of 6 inches. Beans that aren't provided sufficient water will experience slow growth, wilting and poor pod growth.
Spread a second application of fertilizer once the green plants start producing their first set of pods. This provides a midseason boost to encourage continued growth and rapid bean pod development.
Watch for pests. Common pests include beetles and caterpillars, according to the University of New Hampshire. The university recommends removing the pests by hand or treating your green bean plant with any pyrethrum-based herbicide labeled for use on vegetables.
