Tall fescue and/or Kentucky bluegrass
- Start watering as needed. If no rain occurs, water infrequently to a depth of 6 inches once or twice a week. Heavy soils may need 2-3 shorter pulses of water to prevent puddling and runoff. Don't overwater, as drought stress will be much less detrimental than overwatering. Water early in the morning rather than at dusk to reduce disease occurrence.
- Rapidly growing lawns may need frequent mowing (once a week). Taller mowing heights of 3 1/2 to 4 inches are required to enhance turf quality and reduce weed infestation.
- Only mow if the turf is growing, so do not mow drought-stressed turf. Restrict mowing saturated or water-logged areas which may cause ruts and will increase compaction.
- Use a mulch mower to integrate clippings. Collecting clippings will increase fertility need of lawn. Do not leave clippings on lawn surface as it will encourage disease. Rake in or mow again to incorporate clippings.
- If fertilization is necessary, apply at a very low rate of 0.25 – 0.5 lb N per 1000 sq ft. On established lawns, focus most fertilization efforts in September and October.
- Scout for brown patch disease and sod webworm damage and treat if necessary.
