Epsom salts good for roses?

[MaggieM]

So, I've read that Epsom salts are good for roses?

This spring, I planted some climbing roses. I didn't know how to shop for them, so just grabbed the healthiest looking ones. Some are doing fine. One is slow to grow, and one appears dormant. I put a little commercial composted manure in the holes before planting them. They get plenty of water and sunlight. Kind of feel like I should do something else. Any ideas?

Epsom salts is magnesium sulphate.

I would use a proprietary rose fertiliser to give a balanced feed.

Relax Maggie.....i would simply keep your plants well watered for now
Hope you mixed that dried manure with soil though. A balanced feed at planting time and Fish blood and bone is ideal
However, epsom salts is always beneficial......a general tonic.....and something
I use on tomatoes and anything looking slightly "yellow"

Hi, if you got hold of a pack of pure MgSO4 /epsom salt then be careful while using it. Plant need a small quantity( trace). So, dilute it then use.

May be 48-60mg/L
