Have some of this but none of that for gritty mix
I have decided to place one of my young palms into my first (well really 2nd) batch of gritty mix. It is a palm native to southern inland California/Nevada and are native to alkaline soils. I have a fertilizer that contains Mg but not calcium. Here is the problem my fert is in granular form not liquid form and I am having a hard time finding gypsum in my area. I do however have some d. lime on hand and was wondering if both the granular palm fert and adding d. lime to increase the ph will be acceptable for use in the gritty mix?
