Lawns First Mowing of Spring
Spring is only a few weeks away. Many homeowners are anxious to mow flowering winter annual weeds and to remove much of the old dead leaf canopy from the previous summer. I receive several calls each spring asking if a lawn can be burned or mown very low (scalped) in early spring and the reply is yes but with reservations and restrictions.
I strongly discourage burning. This practice is usually not very uniform, the liability risk is great, it creates smoke and soot to deal with, and many communities have ordinances that forbid burning.
Lawns of bermudagrass or zoysia can be cut very low (scalped) since they have a strong network of rhizomes (below soil runners) and stolons (above ground stems) that will quickly replenish the turf canopy with new rejuvenated growth if soil and air temperatures are warm enough for growth. Centipede and St. Augustine lawns can also be cut slightly lower than their optimum mowing height but should not be “scalped” as they have only stolons to develop a new canopy. Scalping or close mowing should not be a continuous process throughout the season but only once when the lawn begins its initial spring growth.
Since there will be an excess of old clippings being removed, this may be a time to collect clippings rather than leaving them on the lawn. They then should be utilized as compost and not considered trash to fill our landfills.
