two tbsp per two gallons of water?
Hi Emma. I'm Cindy. Yes, you have the exact amount to be used. And, yes, it's safe to use this solution on your hostas. Be sure to pour it on the soil at the base of the plant, not the leaves. Good luck Emma.
Can you use this mixture on all plants?
Yes, Epsom salts help plants if it is diluted in water. I use 2 Tbsp per gallon, but yours will work for sure too.
You can use it on tomatoes so it should not hurt the hostas.
Hi Emma. It's Cindy again. Yes, you can use this mixture on all plants. You can also use it on your lawn. I usually use this solution every 2 weeks or more. It replaces the enzymes in the soil that are depleted over time. Plants thrive with it. Good luck Emma.
