Is this the same as Epsom salt from a pharmacy?

Chemically yes, both are magnesium sulfate. This bag is sold as a fertilizer grade for soil and fertigation, so follow the label rate rather than bath or wellness doses.

How much do I apply per plant or per 1,000 sq ft?

Rates depend on your soil test and crop. Common garden guidance is about 1 tablespoon per gallon of water for a drench or roughly 1 lb per 100 sq ft, but confirm against the bag label.

Can I use it in a drip or fertigation system?

Yes. It is extremely soluble, which is why fertigation is a listed use. Dissolve it fully in water first and flush lines after the season.

Will it help sandy soil?

It adds magnesium and sulfur, which sandy, low-CEC soils lose quickly. It does not build water-holding capacity, so pair it with organic matter.

Is it safe around pets and livestock?

The listing says it suits every animal species and early lactating dairy cows. Keep the bag sealed and out of reach, and dose animals only on veterinary or extension advice.

When is the price lowest?

We have one dated price: $26.00 at Standish Milling Company as of November 6, 2026. Bulk mineral prices move with freight, so compare the four stores before a large order.
