green bean germination
Propagate by seed - Do not start seeds inside. Beans do not like to be transplanted.
Germination temperature: 70 F to 80 F - Germination is slow and poor when soil temperatures are below 60 F.
Days to emergence: 8 to 10 - Germination may take two weeks or more if soil temperatures are below 60 F.
Seed can be saved 5 years.
Maintenance and care: Do not plant until danger of frost has passed and soil has warmed. Germination is poor when soil temperature is below 60 F. Cold air temperatures (even above freezing) can injure plants and reduce yields.
Construct trellis, teepee, or single-pole support before seeding to avoid injurying plant roots later. Bamboo poles or saplings lashed together make easy, inexpensive supports. Do not locate trellis where it will shade other plants that need full sun.
Plant seed 1 inch deep (deeper if soil is dry), in hills of four to six seeds at the base of each pole. Plant 3 inches apart in rows along the base of linear trellises.
Soaking beans to hasten germination may damage seeds. Do not start seed inside.
Beans require even moisture - about 1 inch per week - especially when flowering and developing pods. If you water, avoid wetting foliage, which encourages disease. Water early in the day so foliage dries quickly. Mulch after second set of true leaves develops to help retain moisture.
Do not use nitrogen fertilizers. Inoculating seed with rhizobium bacteria may increase yields, especially in soils where beans have not been grown before.
Pod set is often poor when temperatures exceed 90 F.
Deformed pods may be the result of lack of moisture, poor soil fertility or insect damage during blooming.
A three-year rotation helps reduce some diseases.
Pests: Mexican bean beetles - Handpick and destroy beetles and eggs in small plantings. Plant early to avoid this pest. Turn under any infested plants after harvest.
Aphids - A hard stream of water can be used to remove aphids from plants. Wash off with water occasionally as needed early in the day. Check for evidence of natural enemies such as gray-brown or bloated parasitized aphids and the presence of alligator-like larvae of lady beetles and lacewings.
Leafhoppers - Small, light green to gray wedge-shaped insects that suck plant juices, causing stunting, and carrying virus diseases. No cultural control available.
Seedcorn maggot - Avoid heavy manure or organic matter in garden which attract maggot flies and encourages egg laying. Purchase insecticide-treated seed. Use gloves to plant.
Spider mites (two-spotted) - Wash off with water occasionally as needed early in the day. A hard stream of water can be used to remove many mites from plants.
Diseases: To reduce disease spread, do not work among wet plants.
Bacterial blights - Avoid wetting foliage if possible. Water early in the day so aboveground plant parts will dry as quickly as possible. Avoid crowding plants. Space apart to allow air circulation. Eliminate weeds around plants and garden area to improve air circulation. Do not save your own seed.
Bean common mosaic virus (BV-1 and NY 15) - Remove and discard or destroy entire infested plant along with immediately surrounding soil and soil clinging to roots. Use resistant varieties: Lancer, Provider, Blue Bush 274, Golden Butterwax, Royal Burgundy, Tendercrop, Improved Tendergreen. Manage insect vectors.
White mold - Avoid wetting foliage if possible. Water early in the day so aboveground plant parts will dry as quickly as possible. Avoid crowding plants. Space apart to allow air circulation. Eliminate weeds around plants and garden area to improve air circulation. In autumn rake and dispose of all fallen or diseased leaves and fruit.
