Epsom Salt is magnesium sulfate so it isn't of any use for BER, and it all depends on what is the cause of the leaf wilt, whether it's due to a disease, environmental reasons, lack of water, or whatever,

Regardless of he cause I can't see Epsom Salts as helping with wilting leaves.

I should add that when soils are too acid, Ca++ is not taken up by a plant that addition of Epsom salts can alter those acidic conditions and allow for some Ca++ uptake, which refers to BER.

And if you have some Palm Trees where you are or any green tree or bush, that needs greening up, spraying with Epsom salts can help. And that's b;c the central ion in chlorophyll is Mg++ so that's why it works.

For many years the folks in FL sprayed their Palm Trees with Epsom Salts before the tourists arrived for the season so they could see green, not yellow, fronds swaying in the breeze. ( smile)

Summary? You need to know why the leaves are wilting before folks can make some suggestions, so if you could post a picture, that would be great, if not, if you could describe the situation in more detail that might also help.

Agree. Could you provide more details about what you mean by "leaf wilt"? Leaves may wilt for all sorts of reasons, some of them terminal, many of them fixable but not with epsom salts AFAIK. And a close up photo would be a big help.

IMO Epsom Salt is no a cure for wilting leaves. As stated it is just a source of Magnesium, and sulfur.
I think Dolomitic Lime is a better choice to prevent BER, provided you pH is not too high. If I remember it correctly, DL has also magnesium. Most tomato fertilizers have Magnesium and some (MG shake n feed slow release) have clacium too.

The best/ideal way to prevent BER is to maintain evenly moist soil/media.

Yes, it might be. But then it is easier to be said than done. Unless you have a sophisticated computerized moisture monitoring system to act automatically right on time.
BER is more involved than some think. and adding eggshell and antacid tablets is not going to cure it.
Genetics is the strongest factor. Say you plant San Marzano and Big Boy side by side. Bog boy does fine but SM get BER. Then that happens early in the season. So what is special about early season ? Maybe, cool soil temps, cool air temps. But still, Big boy does fine ? So it is the genetics of the variety that its root system is not capable of taking up calcium at that stage and growing conditions.

The original question was about wilted leaves, so that's what I'm waiting to hear about from the original poster,

Heaven knows there are several excellent recent threads here about BER , and I suppose I could link to what I thought was one of the best, but I'd rather try to help with the wilted leaf problem, if I could.
