Many flowers thrive in fall's cooler weather.

In most parts of the country, September marks the time when the temperatures begin to drop. The days are still warm, but no longer hot, and nights are chilly. Fall colors begin to emerge and compete with flowers for attention in the garden. This is the time many cool weather annuals and perennials are available. These flowers will bloom in your garden until the first winter frost as you enjoy the last blooms of summer blooming plants.

Roses add color and scent to the fall garden.

Although roses are generally considered a summer blooming flower, most of them are still sending out flower buds in September. In hot climates, the roses may recover from high summer temperatures by a show comparable to the first spring flowers. In cooler climates, the flowers may be smaller and less frequent, but no less beautiful. Don’t feed your roses in September as this will cause the plant to grow new leaves right before it should go dormant.
