Space rows 4 to 5 feet apart. Fertilizer Apply lime and fertilizer according to a soil test. Lime should be applied 3 months before planting. Apply fertilizer 10 days to 2 weeks before planting. Irrigation Without irrigation, lima bean yields are inconsistent and quality may suffer.
Soil moisture is particularly important during blossoming and pod set.
Dry soils will result in blossom drop and small pods. Weed Control Keep cultivation shallow to prevent injury to the surface feeder roots. Do not cultivate when plants are wet, since this may spread disease. A number of herbicides are labeled for use on lima beans. Treflan or Prowl may be incorporated before planting.
