September in the garden is a special time!
This month marks the end of monsoon season. The intense heat and humidity of summer is mostly past, and the mercury is beginning to fall, especially overnight. Now is a good time to clean up any monsoon damage from storms or wind and prepare your beds for new plants.

Look forward to starting your fall vegetable crops as the temperatures begin to wane toward month's end. And do not forget to sit back and enjoy a cool evening breeze now and again while enjoying the fruits of your labor.
