Uses of Dolomitic Lime
Recently there have been some discussions regarding the use of Epsom Salt (MgSO4)on certain orchids. Others have recommended the use of Ca as part of the food mix and the MSU formula contains Ca along with other "stuff". I found a product called "Garden Lime" made by Espoma. Its composition is:
Ca ~ 21%
Mg ~ 10%
CaO ~ 29%
MgO ~ 17%
CaCO3 ~ 52%
MgCO3 ~ 35%
In small quantities think it would be safe to use, like 1/2 t per gal? This is just a guess/starting point. And it is something to use maybe once a month or so. What are your thoughts, please.
