epsom salt on bonsai

Posted by mganga_mulapali MD (My Page) on

For years, I have used a tsp or tbs (depending on size of tree in pot) of epsom salt each spring and fall on all junipers and pines. The trees have good green color. Recently had a debate with someone about the value of this. I found nothing on the internet about the use of epsom salt. Any comments or directions?

It's really well known to be a good thing for them, and a fair number of people do it, so if it works for you, spread the word :-).

I'm lurking on the Bonsai forum. I potted a maple last summer and it is growing very well. I'm just looking for some tips. We used to show and judge seasonal flowers. The flower was 80 points and the leaves and stems were worth 20 points. The gorwers knew to add Epsom salts about 3-4 weeks before the shows to "green-up" the leaves and stems. It wasn't a secret, it was a well acknowledged fact. Epsom salts also promotes bud formation.

From good ol' Wikipedia, for some quick info:

Agricultural use

In agriculture and gardening, magnesium sulfate is used to correct magnesium deficiency in soil (magnesium is an essential element in the chlorophyll molecule). It is most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, roses, and tomatoes. The advantage of magnesium sulfate over other magnesium soil amendments (such as dolomitic lime) is its high solubility.
