We have had a warm, dry September. Though it has allowed us to spend more time outdoors, some plants may be showing drought stress in any areas that do not have controlled irrigation. This is a crucial time for plants to have adequate water, as they prepare for winter dormancy. Most energy is being directed to root growth and they need moisture. Lack of water in fall can lead to winter burn and could be fatal to some trees or shrubs.
Check the soil around your gardens - if it seems dry and dusty, give the beds a drink. Slow and steady watering will help the water get deep into the ground and encourage roots to grow deeper as well. Consider using a drip hose that runs for extended periods for the most efficient application. Rain may help, but keep in mind that a quick downpour does not allow time for the water to be absorbed and usually results in runoff. Also, a dense tree canopy above will prevent most of the rain from touching the ground at all.
