Ohhhhh.
Follow on.
Your Sprinklers are, if like mine, on their own branch circuit. So that may be a second issue.
As for your Freezer. Look at your breaker box and see if you have any spare (blanks) circuits. My box has zero. Hence wiring everything up under the Sun on one branch.
Get an electrician if you have open blanks to run a dedicated branch for that freezer (best method.. recommended). This can be done quite easily using metallic conduit..... direct..... no need to break into the walls
If you keep a lot of food, buy a quality UPS for the freezer, it will mitigate power surges and keep the freezer going for the short term , most presumably power will return shortly and all will be good.
Your freezer. It's motor does not like power spikes. It will just short out and stop working.
