High Drought Exposure
The county endured 6 weeks of drought over the last year, the highest among its peers. While current conditions are stable, the history of dry spells suggests that installing a smart irrigation system could save your turf in the long run.
Tough Grasses for Metcalfe
Heat-tolerant varieties like Tall Fescue or Bermudagrass are best for this environment. Plant your seeds between the last spring frost on April 26th and the first fall frost on October 18th to maximize the growing window.
