I groom pretty much daily. My filly can have her evening hay and her "grain" (strategy and supps) in front of her and she'll stand for me (without tying) as long as I want to groom her! So I usually give her a 30 min. Session in the eve at the very least.
I groom my horses before and after I ride I also groom them when ever I catch them. My horses are rugged 24/7 so they don't need as much grooming as the horses that are un-rugged. But every time I do groom them they love it lol.
I groom my horses before and after I ride. Each horse is groomed at least twice a week thoroughly and their hoofs are picked once a day. Grooming lasts from 30 min- 1 1/2 hours. I'm a grooming fanatic. We groom at the cross ties.
Before every ride & after every ride during the winter. Once the weather warms up I groom before I ride & hose off afterwards. I also groom on days I don't ride before I put them up for the night. It takes me about 15-20 minutes to groom.
