Growing Tips
Never cultivate or harvest beans when foliage is wet; this spreads bacterial blight and other foliar diseases rapidly.
Succession-plant bush beans every 3 weeks for continuous harvest; a single planting only produces for 2-3 weeks.
Beans fix their own nitrogen; avoid high-nitrogen fertilizer which promotes lush foliage at the expense of pod production.
