Green Bean Care

Phaseolus vulgaris

An easy-to-grow legume that fixes nitrogen from the air into the soil. Pole varieties need support; bush (dwarf) varieties grow without it.

Frost-tender (protect from frost) · 1 °C / 34 °F

Monthly care calendar

Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.

May
  • Watering: If there is no rain, water 1-2 times a week; the soil should not stay constantly wet.
  • Fertilizing: Beans fix their own nitrogen; mixing in compost alone before sowing is enough, and nitrogen fertilizer only encourages leaf growth.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: Sow the seeds directly 3-4 cm deep once the soil has warmed to 15 °C; leave 40-50 cm between rows for bush beans and 70-80 cm for pole beans. For pole varieties, set up 2-2.5 m stakes at sowing time.
  • Pests & diseases: Look for aphids (green or black clusters of small insects) on fresh shoot tips. If there are only a few, you can knock them off with a strong jet of water.
  • Frost risk: Cover emerging seedlings on cold nights; beans die if touched by frost.
June
  • Watering: Water deeply at the base 2-3 times a week, in the early morning; do not water again until the soil surface has dried 2-3 cm down.

  • General care: Do not work among wet leaves and do not water in a way that wets the leaves; diseases spread with water.

July
  • Watering: Water deeply at the base 2-3 times a week, in the early morning; do not water again until the soil surface has dried 2-3 cm down.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: You can extend the harvest into autumn by making a second sowing in late June-early July.
  • General care: Harvest: Pick the pods every 2-3 days while still tender enough to snap when broken, before the seeds inside become prominent.
  • General care: Do not work among wet leaves and do not water in a way that wets the leaves; diseases spread with water.
  • Pests & diseases: In hot and dry weather, look on the undersides of the leaves for fine webbing and speckled yellowing (spider mites). Washing the leaves during the cool hours reduces their numbers.
  • Pests & diseases: Check the undersides of the leaves for orange-brown pustules (rust).
August
  • Watering: Water deeply at the base 2-3 times a week, in the early morning; do not water again until the soil surface has dried 2-3 cm down.
