I saw an article pertaining to "Global Buckets" Self Watering Containers that showed a photo of the analysis panel on a bag "Garden Lime" with the Calcium Carbonate (CaCO3) at 53.93% and Magnesium (MgCO3) 45.36%.
I checked mine to see what ratio mine had and found it to be CaCO3 82.5%, and MgCO3 at 8.36%.
I was thinking I was not providing enough Magnesium, so I did some research and found that a 10/1 ratio of Calcium to Magnesium was preferred...but the articles were based on LAWN GRASSES, not house plants, garden plants, vegetables and the like.
I recall reading that too much Calcium can can cause problems with Magnesium uptake.
SO...is the 10/1 ratio good for all plants, or is it just a lawn thing?
