|Would Epsom salt be good for lawn?
I live in Oregon.
|Epsom salt is a good source of magnesium and sulfate, but chances are that your lawn does not require an excess of these elements. In the Portland area your soil is already acidic due to your heavy rainfall - additional sulfur will simply lower the soil pH that much more which can cause minerals to be bound up in the soil and not readily available to the roots of your turfgrass. Epsom salt is often proposed by home owners and tv-gardening gurus for a variety of gardening problems, but in reality it probably will not solve your problem - at least not for more than a week or two.
