calcium?
 

:hello I am hoping someone could give me a bit of advice. My water in Ontario is lacking in calcium as I am getting some light borders on some of my orchids (phals). I purchased some dolomitic lime pellets and have no idea if I am supposed to crush them up or drop a couple on the top of the pots, or dissolve them in water. The components are (CA) 21% (Mg) 12% (CaCO2) 70%. Will this be ok to use? I have just started giving my orchids epsom salt once per mo. as was recommended to me, if I use the dolomitic lime should I stop the epsom salts? I also have 1 maudiae slipper and I understand that they need lime, would this be ok to use on it? Thanks for the help :biggrin:

I'm not sure about the lime as you would need to find out how much to apply. However, if you use a well balanced fertiliser it will have all of the calcium you should need - but I may be wrong. ;)

Unfortunately all the fertilizer I can find up here has no calcium or magnesium in it. Hopefully someone can chime in to help me out. Thanks kelo :)

No worries bud. Try typing 'fertilizers' into the search bar at the top right and see what you dig up. There all be tons of info on the site. :D
