Can I use Espom salt and or coffee grounds in my gardina plant it's in a large container. If so how much and how often? Also the same question for my hydrangea bush except it's in the ground. I live in Wortham Tx. Thanks so much. The gardina is in a container outside.
You can use either if the plant is deficient in something that either contains. Do you have a reason to believe that the plant has a magnesium deficiency (the reason for using Epsom salts)? Coffee grounds will not likely make the soil more acidic if that is what you are hoping, and in a container I would be careful not to use too much of it.

I agree with Sue that it is important to first determine if and what nutrients are lacking before adding anything. If your plants are doing well, then an occasional application of a complete fertilizer is warranted. Too much of any nutrient can cause damage.
