got them for my palm tree
These are the same as epsom salts. They should not be used in gardens unless you need more magnesium. Too much is not a good thing, so all of the internet stuff recommending epsom salts are really bad advice. But, palm trees often need supplemental magnesium, so I got this. The effect takes time to show, so I am not going to lie and say my palms instantly look great, but this is a decent product and it should work just fine. But no, your tomatoes will not grow better if you add this.
