Many people ask me if they should keep watering their gardens during the fall season and I reply yes especially if you season is dry with no rain in the forecast. Several flowering plants will continue to flourish in the garden until there is a hard frost.
Know that I do not water daily but I do not let my gardens and spring-blooming shrubs dry out. I generally stop watering when there is a hard frost and plants go into a dormant state.
Fall is the season when the weather can be hot, cool, and cold all on the same day. This fluctuation in temperature is hard on plants and generally, they will start to die back. When a plant begins to die back I will clean up the flower bed by cutting the perennial down to the soil or removing the annual. Then add a layer of much to the garden bed.
it is okay to cut back flowers that have been spent. I cut back my Shasta daisies and my Asiatic lilies as soon as the weather changed and nights got cool, the mid-40s.=[ However the days are warm and some days are hot which means my zinnias, at 4 o’clock, black-eyed Susan’s, and Sunflowers still have blooms.
I water my garden plants, and container gardens and also water the spring bulb beds until there is a hard frost. Here are some photographs of late summer and early fall blooming flowers
