Bush beans sown while the soil was still cool and wet showed a poor germination rate and those plants that grew were diseased and attacked by pests. The beans sown a few weeks later when the soil had warmed up and dried out somewhat and the day and night time temperatures had risen, had an excellent germination rate and produce a bountiful crop of beans on healthy plants. Lesson learned – wait until the soil has warmed up before you sow your bean seeds.
