I am not familiar with your climate, but I would say that now is a good time to stop feeding, or otherwise nurturing them. You do not want any new growth on them, this late in the season.
Any new growth will be vulnerable to winter conditions. The plants need to start preparing for winter dormancy now, and any new growth will hamper that process.
As a general rule, I feel that the summer solstice is the cut-off point for any feeding in order to help the trees get ready for winter. Any feeding after that is counter productive to Mother Nature's plans.
