Just wondering if I can mix Miracle Grow with some Epsom salt? OR would this burn the plants? In particular tomato plants, sago palms etc…I live in Yuma AZ and our winter this year has been cold….should I wait until spring?

I would wait till the plants are actively growing to apply any fertilizer.

Depending on the exact M.Gro mix, it may already have magnesium and sulfur in it, which is in epsom salts. Most of the time, extra will not hurt the plant, but will not do much otherwise.
You also can do a soil test to see what nutrients are lacking in the soil.

You may want to alternate using the M. Grow and the epsom salts. Here are more ideas on how to use epsom salts:
