Can I Feed A Boston Fern With Epsom Salts?
Can I use this and do I only feed in the summer. If fertilizer is better, what numbers are best for a Boston? Thanks!

Epsom salt on its own is not a complete fertilizer. This will only provide magnesium and sulfur. These are but a very small part of what a plant will need to survive. This article will help you to feed Boston fern: https://www.gardeningknowhow.com/houseplants/boston-fern/boston-fern-fertilizer.htm
