I live in the mountains of northern California. I'll probably have one more full flush of roses, but I stop dead heading around the first of October because I want the roses to set seed and harden off for winter. I'll still get blooms until the first frost, which may not arrive until mid-November.
In my climate, the day temps can go from the low 90s down to the 50s within a couple of days and night temps drop just as dramatically. I don't want to encourage new growth going into winter. Besides, the hips on some roses are simply beautiful in the winter garden.
Smiles,
Lyn
