Using epsom salt to root cuttings

[figneer]

I know a lot of you like experimenting on new methods to improve rooting so has anyone tried using epsom salt right off the bat to help root new cuttings?

[dondan]

Why should that help? Have you any grounds for thinking it might?

Inert is the name of the game for rooting media. You're in the ballpark for texture, but the highly nutrient rich environment would surely kill anything in direct contact. Fertilizers, which Epsom is, usually are acidic & poison in high concentrations. Soils have numerous properties. Your texture is goodbut media (material using instrad of soil) isnt but youre on the right track! Maybe broken glass with limestone chunks & something with slight absorbent quality like peat or the Optisorb.
Cheers!

Thank you for your response

Epsom salts is still a salt. Sorry, it will kill the cuttings. It will also readily dissolve in contact with water. Likely the same issue with many fertilizers used as a media.

While the issue gets complex, an over abundance of one fertilizer ingredient can block or inhibit the availability of another nutrient(s). PH can also influence the availability.

I amended my post; the narrow range micronutrient between adequate and toxic is boron.

I use Epsom Salt at 1/4 tsp per gallon of water with 1/2 tsp Miracle-Gro All Purpose water soluble fertilizer to Pre-water my Cutting Mix. It provides an initial nutrient charge...

You may need to clarify your question...

Is this suggestion a troll, haha? Dont people pile straight Epsom salt on stumps from trees they cut down to kill them?

[figneer]

As I read and researched that epsom salt help plants absorption of nutrients and if so then the cuttings would be more efficient in absorbing them therefore it will leaf faster and would help getting roots faster, that’s the reason I asked the question

Its great for peppers n tomatoes. Or you can foliar spray CalMag. Epsom salt is nice and cheap. I will add it to my figs a few times a year as part of my feeding schedual.

Ah, ok. Yes, many members add Epsom salt to their fertilizing regimen. Not sure the best way to get it into a cutting in order to help rooting thogh. Maybe diluted in a soak? Not sure if this would be good or not.
