Adding Chalk to Paph mix for lime needs

[kaarthiik]

Hi Guys,

I would like to know if we can cad add Chalk to Paphs as supplement for lime ? Just got the idea that Chalk is a form of limestone.

In my area, I cannot get a horticulture grade lime to add, I had to import but it would take time.

For now I am adding some Egg shell powder (done by me).I add a pinch to two for a plant of BS (not big plants, medium) Is this enough?
I use MSU as fertilizer at 70 PPM N - 3 to 4 times a week.

Please also suggest any other easily available supplements for lime.


Thanks,
Kaarthiik
