Occasionally, during hot summer months, St. Augustine grass may suffer from iron chlorosis, which means that the plant is not getting enough iron. This is probably because the soil is too alkaline. Alternating yellow and green streaks running lengthwise along the grass blade is a clear indication of this. Apply an iron chelate to the lawn. Iron does stain concrete, so do not spread it across sidewalks or driveways.
In The Woodlands and in many areas of the state, water utilities employ The W.I.S.E. Guys (Woodlands Irrigation Systems Evaluations) to check their sprinkler systems. It is a free service.
Keep mower blades sharp so they make clean – not ragged- cuts. Ragged cuts damage the individual grass blades and weaken the structure of the lawn.
It’s possible to seed or sod a lawn this month, but remember, the summer heat will create much more watering.
