Introduction to Mowing
« on: April 07, 2011, 04:03:31 PM »

Proper cultural practices are essential to the success of organic turfgrass. Although an organic management plan is always dictated by each field’s or lawn’s unique site and soil conditions, basic guidelines can be used when getting started. Important cultural practices in an organic management program include mowing, aerating, seed selection, overseeding, dethatching and irrigation.

Mowing height and frequency are key in the healthy development of organic turfgrass. Mowing is a major stressor of turfgrass and mowing practices should strive to minimize this stress as much as possible. To accomplish this, remove only 1/3 of the leaf at each cutting.  The height of the leaf length also has a large impact on turfgrass density, thickness and root depth.  Best results are seen through raising the height of the cut to 3 to 3-1/2 inches.

Leaf length is kept high in organic management for a variety of reasons. Long leaves lead to more energy production and consequentially more vigorous root growth.  Deep roots work to produce a more drought tolerant plant.  Taller leaf length shades the soil preventing weed germination and cooling the  soil surface preventing scorch during times of excessive heat. Long leaf length, overseeding and a deep root system work in concert to produce effective weed control.  

Longer leaf length is not always possible when maintaining athletic fields.  Look for periods of time where you can raise the cut and let turf build energy reserves. Schedule your cuttings immediately before important sport events.  If grass is always cut short, mowing more frequently can help control weed growth.
