My pH well below six ..
Can I use this product to raise my PH in my soil. I'm growing out of 13 litre pots.
In the pictures below in the pots I have about 2 and a half inches play should I add lime and soil together and spread it.
Listed on the box ingredients
Contains:
Calcium Oxide 46% Magnesium Oxide 15%
I should of added lime at start. Noob mistake .

Turf'-- That box is labeled wrong somehow! CaO is super caustic, so not safe or even intended for garden use 
... garden lime, agricultural lime, dolomite lime are the normal forms used, each having a slightly different formulation in terms of the Ca and Mg carbonates they have,.. dolomite is the slowest of them all, because of the slightly different arrangement of the molecules; particle size makes a big difference too... yes, they are all best used mixed into the soil, top dressing is slow, inefficient and possibly damaging if used in excess as such,... another "lime " is hydrated lime, Ca(OH)2, an very fast, powerful pH adjuster, not as nasty as quick lime, but it can certainly roast a plant if used wrong! Another problem is that even if you powder it, put it in solution, it still won't penetrate evenly into the soil, it will be filtered out by the soil, and can make a clay-like layer that messes with water penetration, nute chemistry, etc.,... all of this is unnecessary if you don't have a Ca-mg problem, and if you do, it can be solved by using a Ca-Mg product instead,... have you taken a soil pH reading yet? that's also very important , to determine if you should be raising the pH at all to begin with.. that's what limes do, beside slow release of Ca/Mg,.....
