Plant/Pest of the Month 

September:  Lawn RustLawn rust

If walking across your lawn in late summer results in an orange powder on your shoes, your lawn may be infected with rust.  Rust is a fungal disease that can occur in turf with low fertility.  Cool nights with heavy dew and light, frequent rainfall add to the ideal conditions for rust to develop.  For information about lawn rust and its control see:
