How to Grow Snake Beans in Tropical Australia

Soil
Full sun and soil enriched with organic matter (Diggers). Well drained, because waterlogged soil causes crown and root rot (Seeds of Plenty).
Salt
Moderately sensitive. Copes with a little salt, but the harvest drops on salty bore water.
pH Range
5.5-7.5
Sunlight
Full sun (Diggers).
Spacing
30cm apart
Watering
Water regularly, especially in flowering and pod development. Keep the soil moist but not soggy, and water more in hot or windy weather (Seeds of Plenty). Southern areas need extra watering (Diggers).
Good companions
Nasturtium, Cucumber, Carrot, Sweet Corn, Rosemary
Keep away from
Fennel, Garlic, Onion
Grow before it
Roots and alliums (Carrot, Beetroot, Onion)
Grow after it
Leafy greens and brassicas (Lettuce, Silverbeet, Broccoli)

Give the bed 3 turns before legumes go back in. Beans and peas fix nitrogen, so they leave the bed richer than they found it.
