However, fields should be monitored much more closely for disease and insects. Pruning with mowers is just another way to remove the blueberry stem and stimulate the plant to put out new shoots from the rhizome. Flail mowers appear to be best suited for mower pruning because the configuration of the blades prevents damage to the mower in rocky conditions. Rotary mowing of small fields with a lawn-type mower is feasible if the operator is careful not to hit rocks and scalp knolls. Plant residue left on the soil surface improves water holding capacity of the field.
Soil erosion caused by raindrop splash and water run-off is reduced.
Increased levels of organic matter will reduce leaching of pesticides into the groundwater. As the organic matter content of the soil increases, the availability of plant nutrients should also increase. Increased organic matter on the soil surface may help rhizome spread because of moderated soil temperatures. Bush cutting done after harvest with a rotary mower to reduce weed stems is not needed. The flail mower will cut bushes one inch in diameter and larger, depending on the type of flail mower and the condition of the blades.
