Too early to fertilize?

Some bulbs are popping, irises have some new growth, and even some of my roses are budding. I’m from the area, so I’m well aware we’re not out of the woods at all as far as cold weather goes, but what is your opinion on fertilizing around this time of year?

I have a few yards of hemlock mulch arriving this morning, and my thinking was that I’d spread some slow release organic fertilizer around my beds before covering with mulch. Is it too early though? If I spread it now, it’ll take a while to break down and absorb, and I’m hoping that by the time plants come out of dormancy they’ll wake up to a nice breakfast around their roots.

I have a variety of shrubs, ferns, and bulbs in the beds I’m planning to do this in, and was thinking I’d use rose fertilizer for…the roses, then some general fertilizer (probably a 4-4-4?) around everything else. I usually use Down to Earth fertilizer, but what’s your fav brand?

Thanks!
