Full spectrum nutrition for increased green bean quality

Green beans are arguably one of the lesser demanding vegetables when it comes to nutrient requirements. A balance of nitrogen, phosphorus and potassium is necessary – but too much can reduce plant quality, promoting soft growth and increasing the incidence of disease and insect infestation.

Nutritional needs

Fertilizer needs for green beans will vary depending on growing conditions and soil type, but do not generally require high levels of fertilizer. Green beans prefer slightly acidic soil with a pH of approximately 6.5.

Small amounts of calcium, manganese and iron are also required for optimal green bean growth. Soil testing can help determine if adequate amounts are available in the soil, or if these nutrients need to be added.

Watch your nitrogen

Green beans are members of the legume family, and, as other crops in this family, they have the ability to fix nitrogen through a symbiotic relationship with bacteria in the soil.  Because of this, little to no supplemental nitrogen is needed for green beans.  Adding too much nitrogen to the soil can result in too much leaf and stem growth and smaller beans, reducing plant vigor and increasing the chances of pest and disease pressures.

A lack of nitrogen, or nitrogen deficiency, in green beans can be identified by slow growth and pale green or yellow beans.

A balanced approach

Take the guess work out of balancing nutrient needs for green beans with Rainbow Plant Food. A homogenous granular fertilizer, Rainbow Plant Food delivers precise amounts of each nutrient – primary and secondary – along with micronutrients that are all chemically compounded to form a homogenous mixture.

Delivering full spectrum nutrition with all of the essential plant nutrients in one granule boosts yield potential and crop quality. With Rainbow Plant Food, no blending is necessary, since a perfect ratio of essential minerals is contained within each individual granule. No blending means no chance for segregation, and that translates to healthier, more vibrant green bean crops at harvest.
