    March
    1. Buy

    Buy plants and seeds if available at the garden center or via mail-order.
    2. Sow Seeds

    Sow seed indoors for planting outside next month once the plant has two sets of true leaves. Use a loose seed-starting mix and plant seed 1-inch deep. Moisten soil well prior to planting and refrain from watering again until seedlings emerge. Place in a sunny window once seedlings germinate.
    3. Special requirements

    Beans are shallow-rooted, so avoid cultivating around the root zone.
    April
    1. Buy

    Buy plants and seeds if available at the garden center or via mail-order.
    2. Plant

    Plant in a full-sun location with loose, well-draining soil.
    3. Sow Seeds

    Sow seed indoors for planting outside after mid-month once the plant has two sets of true leaves. Use a loose seed-starting mix and plant seed 1-inch deep. Moisten soil well prior to planting and refrain from watering again until seedlings emerge. Place in a sunny window once seedlings germinate. Sow seed outdoors in a full-sun location starting mid-month. Plant seed 1-inch deep in a loose, well-draining soil. Moisten the planting area well before planting and then refrain from watering again until seedlings emerge.
    4. Fertilize

    Feed once with an all-purpose, organic vegetable fertilizer when plants begin actively growing.
    5. Water

    Keep young bean plants evenly moist but not soggy. Mature bean plants can tolerate some dry conditions but require even moisture when they flower and form pods.
    6. Pest/Disease Inspection

    Check for aphids, cucumber beetles and giant whitefly.
    7. Treat for Pest/Disease

    Control aphids by applying a strong spray of water to plants. Repeat once or twice a day until the aphids are gone. Especially heavy infestations of giant whitefly can also be controlled with a strong spray of water. Whiteflies attract a beneficial parasitic wasp that will also destroy them, which is why it's preferable that you don't use any insecticides on the plants, but instead wait for the biological control to do its work. Cucumber beetles do the most damage feeding on young leaves, so cover plants with row cover to keep off the beetles until the plants are more mature.
    8. Transplant

    Transplant plants grown indoors last month outdoors in a full-sun location with loose, well-draining soil.
    9. Special requirements

    Beans are shallow-rooted, so avoid cultivating around the root zone.
    May
    1. Buy

    Sow seed outdoors in a full-sun location, planting 1-inch deep in a loose, well-draining soil. Moisten the planting area well before planting and then refrain from watering again until seedlings emerge.
    4. Fertilize

    Feed once with an all-purpose, organic vegetable fertilizer when plants begin actively growing. Fertilize a second time when plants start producing pods.
    5. Water

    Keep young bean plants evenly moist but not soggy. Mature bean plants can tolerate some dry conditions but require even moisture when they flower and form pods.
    6. Mulch

    Mulch around the root zone with a 1-inch layer of shredded bark.
    7. Pest/Disease Inspection

    Check for aphids, cucumber beetles and giant whitefly.
    8. Treat for Pest/Disease

    Control aphids by applying a strong spray of water to plants. Repeat once or twice a day until the aphids are gone. Especially heavy infestations of giant whitefly can also be controlled with a strong spray of water. Whiteflies attract a beneficial parasitic wasp that will also destroy them, which is why it's preferable that you don't use any insecticides on the plants, but instead wait for the biological control to do its work. Cucumber beetles do the most damage feeding on young leaves, so cover plants with row cover to keep off the beetles until the plants are more mature.
    9. Harvest

    Pick bean pods when the seed starts to swell slightly and they are bright green. Harvest regularly. Avoid letting the pods mature on the plant, as it will stop bearing.
    10. Special requirements

    Beans are shallow-rooted, so avoid cultivating around the root zone.

    Control aphids by applying a strong spray of water to plants. Repeat once or twice a day until the aphids are gone. Especially heavy infestations of giant whitefly can also be controlled with a strong spray of water. Whiteflies have a natural predatory parasitic wasp that will also destroy them, which is why it's preferable that you don't use any insecticides on the plants, but instead wait for the biological control to do its work. Cucumber beetles do the most damage feeding on young leaves, so cover plants with row cover to keep off the beetles until the plants are more mature.
