Due to our highly saline soil and water supply here in SA we have difficulty growing dwarf/bush beans successfully See fact sheet here
I have had success with the climbing varieties Blue Lake and Purple King.
This year I am returning to the Blue Lakes after trialling other types from Seed Saver's Network last year and having no success with them.
These Blue Lake (from Eden Seeds) beans were planted direct into Bed 10 (on 22 Oct 07) which is also a trial Wicker Water Bed along with Tomatoes. The beans are growing at the rear (south end) of the bed on a 1800mm high trellis. They also share the 50% overhead shade structure with the Tomatoes.
Being in a wicker bed they are watered from beneath the surface although when first planted they were watered via an in-line dripper to ensure the germinating seeds were receiving enough water.
Latin Name: Phaseolus vulgaris
Soil: They like a fertile, non-acid, well drained soil.
Sow: Spring and Summer after all threat of frost.
pH: 6.5 - 7
Spacing: 15 cm apart along trellis.
Give a liquid feed of Epsom Salts twice during growing season.
As legumes they do not require high levels of nitrogen in the soil.
Should be harvested as soon as ready to promote further fruit set.
In crop rotation they can follow Fruiting plants like Tomatoes and can be followed by the Cabbage family or other greens.
