I'll usually let the fish decide. I've found once we have a few sunny days and the surface warms up the fish get hungry. Of course here in Arizona that happens around mid January.

Thanks Nimbley, LOL

I have read you should wait till the water is 50-55 degrees, but the cold weather food I have says you can feed them when the water is 42-70 with cold weather food. When my water temp is below 55 the fish hang out at the bottom.

We got into the 80s for a little over a week and I only fed them flake food a couple times (sparingly)We have since dropped back down to 30 or around that at night so I quit feeding them again. The early warm temps & sunshine provided an algae outbreak that they can feast on all they like for now.

I feed my fish plain cheerios to start the season it has worked for me for 20 yrs
